Misophonia — Cannot Stand the Sound of Chewing

Wikipedia: Misophonia, literally "hatred of sound," was proposed in 2000 as a condition in which negative emotions, thoughts, and physical reactions are triggered by specific sounds. It is also called "select sound sensitivity syndrome" and "sound-rage." Misophonia has no classification as an auditory, neurological, or psychiatric condition, there are no standard diagnostic criteria, it is not recognized in the DSM-IV or the ICD-10, and there is little research on its prevalence or treatment. Proponents suggest misophonia can adversely affect ability to achieve life goals and to enjoy social situations. Treatment consists of developing coping strategies such as cognitive behavioral therapy and exposure therapy. As of 2016 the literature on misophonia was very limited (see below). Some small studies show that people with misophonia generally have strong negative feelings, thoughts, and physical reactions to specific sounds, which the literature calls "trigger sounds." One study found that around 80% of the sounds were related to the mouth (eating, yawning, etc.), and around 60% were repetitive.

The proposed criteria for high perceived misophonia in young healthy adults and the association between Misophonia symptoms and noise sensitivity.

Noise & health, 24(113):40-48.

Context: The association between noise sensitivity and misophonia has not been explored in any population, according to the available literature.

Aims: To assess the proportion of misophonia symptoms among young healthy adults, to propose the criteria for high perceived misophonia, and to explore the association between misophonia with noise sensitivity with adjustment for sex, age, perceived anxiety, and depression.

Settings and Design: A cross-sectional study on 1132 medical students, aged 21.4 ± 2.1 years.

Methods and Material: Misophonia symptoms were self-reported using the Amsterdam Misophonia Scale. Nine criteria for high perceived misophonia are proposed. Noise sensitivity was measured with Weinstein scale. Perceived anxiety and depression were measured using the Hamilton Anxiety Rating Scale and the Hamilton Depression Rating Scale, respectively.

Statistical Analysis Used: Multiple logistic regression.

Results: Almost half of the students reported the feeling of irritation against people making provoking sounds. Only one in 10 claimed the feeling of loss of self-control when exposed to provoking sounds. High noise sensitivity and high depression were associated with higher odds of meeting the criteria for high perceived misophonia.

Conclusion: Noise-sensitive students are at higher risk of reporting misophonia symptoms and of being classified with high perceived misophonia. The combination of at least four or more symptoms, which classifies every 10th student with high perceived misophonia, is proposed as a self-assessment tool for epidemiological studies among young healthy adults.

Audiological and Other Factors Predicting the Presence of Misophonia Symptoms Among a Clinical Population Seeking Help for Tinnitus and/or Hyperacusis.

Frontiers in neuroscience, 16:900065.

This paper evaluates the proportion and the audiological and other characteristics of patients with symptoms of misophonia among a population seeking help for tinnitus and/or hyperacusis at an audiology clinic (n = 257). To assess such symptoms, patients were asked "over the last 2 weeks, how often have you been bothered by any of the following problems? Feeling angry or anxious when hearing certain sounds related to eating noises, lip-smacking, sniffling, breathing, clicking sounds, tapping?". The results of routine audiological tests and self-report questionnaires were gathered retrospectively from the records of the patients. Measures included: pure tone audiometry, uncomfortable loudness levels (ULLs), and responses to the tinnitus impact questionnaire (TIQ), the hyperacusis impact questionnaire (HIQ), and the screening for anxiety and depression in tinnitus (SAD-T) questionnaire. The mean age of the patients was 53 years (SD = 16) (age range 17 to 97 years). Fifty four percent were female. Twenty-three percent of patients were classified as having misophonia. The presence and frequency of reporting misophonia symptoms were not related to audiometric thresholds, except that a steeply sloping audiogram reduced the likelihood of frequent misophonia symptoms. Those with more frequent misophonia symptoms had lower values of ULLmin (the across-frequency average of ULLs for the ear with lower average ULLs) than those with less frequent or no reported symptoms. The reported frequency of experiencing misophonia symptoms increased with increasing impact of tinnitus (TIQ score ≥9), increasing impact of hyperacusis (HIQ score >11), and symptoms of anxiety and depression (SAD-T score ≥4). It is concluded that, when assessing individuals with tinnitus and hyperacusis, it is important to screen for misophonia, particularly when ULLmin is abnormally low or the TIQ, HIQ or SAD-T score is high. This will help clinicians to distinguish patients with misophonia, guiding the choice of therapeutic strategies.

Emotion Processes Predicting Outbursts and Functional Impact in Misophonia.

Frontiers in psychology, 13:903142.

Misophonia involves a decreased tolerance to certain sounds and is associated with a range of emotions and emotion processes. In addition to the distress caused by misophonia, some individuals report having aggressive outbursts and significant impact on doing things they would like to be able to do. This study aimed to examine whether misophonia-specific cognitive and emotional processes were associated with misophonic outbursts and impact, and whether these relationships could be explained in part by emotion processes not specific to misophonia. A sample of 703 individuals, 315 of whom identified with having misophonia, completed measures of misophonia, depression and anxiety symptoms, anxiety and disgust sensitivity, interoception and beliefs about emotions. Exploratory correlation and regression analyses were used to build mediation models, which were tested using multiple linear regression. Externalising appraisals (blaming others for causing one's reaction to sounds) were positively associated with misophonic outbursts, and this relationship was partially explained by anxiety symptoms and disgust sensitivity. Sense of emotional threat in misophonia predicted functional impact of misophonia, and this was partially explained by depression symptoms and negative beliefs about emotions. Anxiety sensitivity and interoception were not significant independent predictors of misophonic outbursts or functional impact. These results provide support for the relevance of emotion processes in misophonia and highlight the importance of using multi-dimensional measures of misophonia to improve our understanding of the condition.

Sound Tolerance Conditions (Hyperacusis, Misophonia, Noise Sensitivity, and Phonophobia): Definitions and Clinical Management.

American journal of audiology [Epub ahead of print].

Purpose: For some people, exposure to everyday sounds presents a significant problem. The purpose of this tutorial was to define and differentiate between the various sound tolerance conditions and to review some options for their clinical management.

METHOD: We informally reviewed the literature regarding sound tolerance conditions. The terminology and definitions provided are mostly consistent with how these terms are defined. However, many inconsistencies are noted. Methods of assessment and treatment also differ, and different methodologies are briefly described.

RESULTS: Hyperacusis describes physical discomfort or pain when any sound reaches a certain level of loudness that would be tolerable for most people. Misophonia refers to intense emotional reactions to certain sounds (often body sounds such as chewing and sniffing) that are not influenced by the perceived loudness of those sounds. Noise sensitivity refers to increased reactivity to sounds that may include general discomfort (annoyance or feeling overwhelmed) due to a perceived noisy environment, regardless of its loudness. Phonophobia, as addressed in the audiology profession, describes anticipatory fear of sound. Phonophobia is an emotional response such as anxiety and avoidance of sound due to the "fear" that sound(s) may occur that will cause a comorbid condition to get worse (e.g., tinnitus) or the sound itself will result in discomfort or pain. (Note that phonophobia is a term used by neurologists to describe "migraineur phonophobia"-a different condition not addressed herein.) Conclusions: The literature addresses sound tolerance conditions but reveals many inconsistencies, indicating lack of consensus in the field. When doing an assessment for decreased sound tolerance, it is important to define any terms used so that the patient and all health care professionals involved in the care of the patient are aligned with the goals of the treatment plan. Treatment generally involves gradual and systematic sound desensitization and counseling.

[Misophonia in Childhood and Adolescence: A Narrative Review].

Zeitschrift fur Kinder- und Jugendpsychiatrie und Psychotherapie [Epub ahead of print].

Misophonia in Childhood and Adolescence: A Narrative Review Abstract. Misophonia describes a phenomenon in which the affected children and adolescents show a strong negative physiological and emotional reaction when confronted with specific (misophonic) auditory stimuli (most commonly eating or breathing sounds). Several studies with adults yielded prevalence rates between 6 % and 20 % in various (clinical) samples, but the representativeness of samples was largely limited. More than 80 % of the first manifestation of symptoms occurs during childhood and adolescence. Regarding comorbid disorders, studies show great heterogeneity, with estimates ranging from 28-76 % of comorbid mental disorders and approximately 25 % with comorbid physical disorders. The exact etiology is currently not well studied. Initial neurophysiological explanations and imaging studies point to a specific physiological response in misophonia patients. Although many case reports are now available, and diagnostic criteria and measurement tools have been developed, misophonia currently does not represent a distinct neurological, audiological, or psychiatric disorder in the DSM-5 or ICD-11.

Synopsis and Qualitative Evaluation of a Treatment Protocol to Guide Systemic Group-Cognitive Behavioral Therapy for Misophonia.

Frontiers in psychiatry, 13:794343.

Misophonia is a disorder in which patients suffer from anger or disgust when confronted with specific sounds such as those associated with eating or breathing, causing avoidance of cue related situations resulting in significant functional impairment. Functional magnetic resonance imaging studies suggest misophonia is associated with increased activity in the auditory cortex and salience network, which might reflect increased vigilance toward specific misophonia triggers. New treatments have been developed and investigated in the last years in which this vigilance plays an important role. This is a synopsis of the first group protocol for systemic Cognitive Behavioral Therapy (G-CBT) for misophonia. We discuss the model of CBT for misophonia, provide a detailed guide to the treatment illustrated with a case study, discuss advantages, limitations, and possible pitfalls by a qualitative evaluation of the protocol, and review evidence for the protocol.

Hyperacusis and Misophonia: A Systematic Review of Psychometric Measures.

Journal of the American Academy of Audiology [Epub ahead of print].

BACKGROUND: Hyperacusis can be defined as intolerance of certain everyday sounds, which are perceived as too loud or uncomfortable and which cause significant distress and impairment in the individual's day-to-day activities. Misophonia is defined as a high magnitude of emotional and behavioural reaction to certain sounds produced by human beings, such as eating sounds and breathing sounds. Several psychometric instruments have been developed to assess symptoms and the impact of hyperacusis and misophonia; however, to the author's knowledge, no study has evaluated and compared the methodological quality of the studies on psychometric properties of the existing instruments.

PURPOSE: To systematically review the research studies assessing the psychometric properties of the instruments used for hyperacusis and misophonia and assess the quality and appropriateness of the methodologies used.

RESEARCH DESIGN: Systematic review.

DATA COLLECTION AND ANALYSIS: A systematic literature search was performed using five electronic literature databases (PubMed, Scopus, PsycINFO, Google Scholar and Web of Science). Studies were included if they were written in English and reported information about the psychometric properties of instruments measuring hyperacusis or misophonia symptoms or their impact. The quality of the studies and that of the psychometric instruments were evaluated using the consensus-based standards for the selection of health measurement instruments (COSMIN) tool.

RESULTS: The title and abstracts of 916 articles were screened and 39 articles were selected for full-text evaluation, with 14 articles meeting the inclusion criteria. From these 14 articles, eight different instruments (5 for hyperacusis and 3 for misophonia) were identified and reviewed comprising: (1) Hyperacusis Questionnaire (HQ), (2) Inventory of Hyperacusis Symptoms (IHS), (3) questionnaire on hypersensitivity to sound (GUF), (4) Hyperacusis Handicap Questionnaire (HHQ), (5) Short Hyperacusis Questionnaire, (6) Amsterdam Misophonia Scale (A-MISO-S), (7) MisoQuest, and (8) the Misophonia Questionnaire (MQ).

CONCLUSION: None of the papers reviewed reported all the information required to meet the COSMIN standards. The studies' methodological quality varied between 'very good' and 'inadequate' depending on their grade on the COSMIN tool. There is a need for further research on the psychometric properties of the instruments included in this review.

The Relationship Between Self-Reported Misophonia Symptoms and Auditory Aversive Generalization Leaning: A Preliminary Report.

Frontiers in neuroscience, 16:899476.

Misophonia is characterized by excessive aversive reactions to specific "trigger" sounds. Although this disorder is increasingly recognized in the literature, its etiological mechanisms and maintaining factors are currently unclear. Several etiological models propose a role of Pavlovian conditioning, an associative learning process heavily researched in similar fear and anxiety-related disorders. In addition, generalization of learned associations has been noted as a potential causal or contributory factor. Building upon this framework, we hypothesized that Misophonia symptoms arise as a consequence of overgeneralized associative learning, in which aversive responses to a noxious event also occur in response to similar events. Alternatively, heightened discrimination between conditioned threat and safety cues may be present in participants high in Misophonia symptoms, as predicted by associative learning models of Misophonia. This preliminary report (n = 34) examines auditory generalization learning using self-reported behavioral (i.e., valence and arousal ratings) and EEG alpha power reduction. Participants listened to three sine tones differing in pitch, with one pitch (i.e., CS+) paired with an aversive loud white noise blast, prompting aversive Pavlovian generalization learning. We assessed the extent to which overgeneralization versus heightened discrimination learning is associated with self-reported Misophonia symptoms, by comparing aversive responses to the CS+ and other tones similar in pitch. Behaviorally, all participants learned the contingencies between CS+ and noxious noise, with individuals endorsing elevated Misophonia showing heightened aversive sensitivity to all stimuli, regardless of conditioning and independent of hyperacusis status. Across participants, parieto-occipital EEG alpha-band power reduction was most pronounced in response to the CS+ tone, and this difference was greater in those with self-reported Misophonia symptoms. The current preliminary findings do not support the notion that overgeneralization is a feature of self-reported emotional experience in Misophonia, but that heightened sensitivity and discrimination learning may be present at the neural level.

Disrupted computations of social control in individuals with obsessive-compulsive and misophonia symptoms.

iScience, 25(7):104617 pii:S2589-0042(22)00889-6.

Misophonia is a disorder in which certain sounds produced by other people lead to intense negative reactions. It remains unknown how misophonia relates to other psychiatric conditions or impairments. To identify latent constructs underlying symptoms, we conducted a factor analysis consisting of items from questionnaires assessing symptoms of misophonia and other psychiatric conditions. One thousand forty-two participants completed the questionnaires and a social exchange task in which they either could ("controllable") or could not ("uncontrollable") influence future monetary offers from other people. Misophonia and obsessive-compulsive (OC) symptoms loaded onto the same factor. Compared with individuals with low Miso-OC factor scores, individuals with high scores reported higher perceived controllability of their social interactions during the uncontrollable condition and stronger aversion to social norm violations in the uncontrollable compared with the controllable condition. Together, these results suggest misophonia, and OC symptoms share a latent psychiatric dimension characterized by aberrant computations of social controllability.

Autistic traits, emotion regulation, and sensory sensitivities in children and adults with Misophonia.

Journal of autism and developmental disorders [Epub ahead of print].

Misophonia is an unusually strong aversion to everyday sounds such as chewing, crunching, or breathing. Previous studies have suggested that rates of autism might be elevated in misophonia, and here we examine this claim in detail. We present a comprehensive review of the relevant literature, and two empirical studies examining children and adults with misophonia. We tested 142 children and 379 adults for traits associated with autism (i.e., attention-to-detail, attention-switching, social processing, communication, imagination, emotion regulation, and sensory sensitivity across multiple domains). Our data show that autistic traits are indeed elevated in misophonics compared to controls. We discuss our findings in relation to models of the interface between autism, sensory sensitivities, and the specific features of misophonia.

The Berlin Misophonia Questionnaire Revised (BMQ-R): Development and validation of a symptom-oriented diagnostical instrument for the measurement of misophonia.

PloS one, 17(6):e0269428 pii:PONE-D-21-25396.

Misophonia is a clinical syndrome which is characterized by intense emotional and physical reactions to idiosyncratic sounds. However, its psychometric measurement is still in the early stages. This study describes the optimization of a self-report instrument, the Berlin Misophonia Questionnaire (BMQ), and addresses its strengths in comparison to existing psychometric measures. This new measure integrates contemporary empirical findings and is based on the latest criteria of misophonia. A cross-sectional online study was conducted using data of 952 affected as well as non-affected individuals. The final BMQ-R consists of 77 items in 21 scales, which were selected using a probabilistic item selection algorithm (Ant Colony Optimization). The results of confirmatory factor analyses, the assessment of reliability, and an extensive construct validation procedure supported the reliability and validity of the developed scales. One outstanding strength of the BMQ-R is its comprehensive measurement of misophonic emotional and physical responses. The instrument further allows for distinguishing between behavioral, cognitive, and emotional dysregulation; the measurement of clinical insight and significance; as well as discerning reactive and anticipating avoidance strategies. Our work offers several improvements to the measurement of misophonia by providing a reliable and valid multidimensional diagnostical instrument. In line with the scientific consensus on defining misophonia, the BMQ-R allows to formally recognize individuals with misophonia and so to compare findings of future studies. Undoubtedly, this measure fills a research gap, which we hope will facilitate the investigation of causes and treatment of misophonia.

Specificity of Affective Responses in Misophonia Depends on Trigger Identification.

Frontiers in neuroscience, 16:879583.

Individuals with misophonia, a disorder involving extreme sound sensitivity, report significant anger, disgust, and anxiety in response to select but usually common sounds. While estimates of prevalence within certain populations such as college students have approached 20%, it is currently unknown what percentage of people experience misophonic responses to such "trigger" sounds. Furthermore, there is little understanding of the fundamental processes involved. In this study, we aimed to characterize the distribution of misophonic symptoms in a general population, as well as clarify whether the aversive emotional responses to trigger sounds are partly caused by acoustic salience of the sound itself, or by recognition of the sound. Using multi-talker babble as masking noise to decrease participants' ability to identify sounds, we assessed how identification of common trigger sounds related to subjective emotional responses in 300 adults who participated in an online study. Participants were asked to listen to and identify neutral, unpleasant and trigger sounds embedded in different levels of the masking noise (signal-to-noise ratios: -30, -20, -10, 0, +10 dB), and then to evaluate their subjective judgment of the sounds (pleasantness) and emotional reactions to them (anxiety, anger, and disgust). Using participants' scores on a scale quantifying misophonia sensitivity, we selected the top and bottom 20% scorers from the distribution to form a Most-Misophonic subgroup (N = 66) and Least-Misophonic subgroup (N = 68). Both groups were better at identifying triggers than unpleasant sounds, which themselves were identified better than neutral sounds. Both groups also recognized the aversiveness of the unpleasant and trigger sounds, yet for the Most-Misophonic group, there was a greater increase in subjective ratings of negative emotions once the sounds became identifiable, especially for trigger sounds. These results highlight the heightened salience of trigger sounds, but furthermore suggest that learning and higher-order evaluation of sounds play an important role in misophonia.

Misophonia: A Systematic Review of Current and Future Trends in This Emerging Clinical Field.

International journal of environmental research and public health, 19(11): pii:ijerph19116790.

Misophonia is a scarcely known disorder. This systematic review (1) offers a quantitative and qualitative analysis of the literature since 2001, (2) identifies the most relevant aspects but also controversies, (3) identifies the theoretical and methodological approaches, and (4) highlights the outstanding advances until May 2022 as well as aspects that remain unknown and deserve future research efforts. Misophonia is characterized by strong physiological, emotional, and behavioral reactions to auditory, visual, and/or kinesthetic stimuli of different nature regardless of their physical characteristics. These misophonic responses include anger, general discomfort, disgust, anxiety, and avoidance and escape behaviors, and decrease the quality of life of the people with the disorder and their relatives. There is no consensus on the diagnostic criteria yet. High comorbidity between misophonia and other psychiatric and auditory disorders is reported. Importantly, the confusion with other disorders contributes to its underdiagnosis. In recent years, assessment systems with good psychometric properties have increased considerably, as have treatment proposals. Although misophonia is not yet included in international classification systems, it is an emerging field of growing scientific and clinical interest.

The prevalence and severity of misophonia in the Turkish population and validation of the Amsterdam Misophonia Scale-Revised.

Bulletin of the Menninger Clinic, 86(2):159-180.

The Amsterdam Misophonia Scale-Revised (AMISOS-R) is a self-report scale that measures the presence and severity of symptoms experienced in response to specific auditory stimuli. This cross-sectional, descriptive study aims to evaluate psychometric properties of the AMISOS-R in the Turkish language and to examine psychosocial factors associated with misophonia. A total of 374 individuals (female/male: 154/220) between 15 and 45 years of age were included in the study. Confirmatory factor analysis showed that the fit indices were at a good level, and they supported the single-factor structure. Test-retest results and Cronbach's alpha coefficient showed that the scale had high reliability. Misophonia scores were also found to be moderately correlated with obsessive-compulsive disorder and neuroticism. The AMISOS-R was found to be a valid and reliable tool to evaluate misophonia in the Turkish language.

The Ethics of Translational Audiology.

Audiology research, 12(3):273-280 pii:audiolres12030028.

Translational research moves promising primary research results from the laboratory to practical application. The transition from basic science to clinical research and from clinical research to routine healthcare applications presents many challenges, including ethical. This paper addresses issues in the ethics of translational audiology and discusses the ethical principles that should guide research involving people with hearing loss. Four major ethical principles are defined and explained, which are as follows: beneficence, nonmaleficence, autonomy, and justice. In addition, the authors discuss issues of discrimination and equal access to medical services among people with hearing loss. Despite audiology's broad field of interest, which includes evaluation and treatment of auditory disorders (e.g., deafness, tinnitus, misophonia, or hyperacusis) and balance disorders, this study focuses primarily on deafness and its therapies.

Poorer Well-Being in Children With Misophonia: Evidence From the Sussex Misophonia Scale for Adolescents.

Frontiers in psychology, 13:808379.

Objective: Misophonia is an unusually strong aversion to a specific class of sounds - most often human bodily sounds such as chewing, crunching, or breathing. A number of studies have emerged in the last 10 years examining misophonia in adults, but little is known about the impact of the condition in children. Here we set out to investigate the well-being profile of children with misophonia, while also presenting the first validated misophonia questionnaire for children.

Materials and Methods: We screened 142 children (10-14 years; Mean 11.72 SD 1.12; 65 female, 77 male) using our novel diagnostic [the Sussex Misophonia Scale for Adolescents (SMS-Adolescent)]. This allowed us to identify a group of children already manifesting misophonia at that age - the first population-sampled cohort of child misophonics examined to date. Children and their parents also completed measures of well-being (for convergent validation of our SMS-Adolescent) and creative self-construct (for discriminant validation).

Results: Data show that children with misophonia have significantly elevated levels of anxiety and obsessive compulsive traits. Additionally children with misophonia have significantly poorer life-satisfaction, and health-related quality of life. As predicted, they show no differences in creative self-construct.

Conclusion: Together our data suggest the first evidence in population sampling of poorer life outcomes for children with misophonia, and provide preliminary convergent and discriminant validation for our novel misophonia instrument. Our data suggest a need for greater recognition and therapeutic outlets for adolescents with misophonia.

Toward a Multidimensional Understanding of Misophonia Using Cluster-Based Phenotyping.

Frontiers in neuroscience, 16:832516.

Misophonia is a condition characterized by hypersensitivity and strong emotional reactivity to specific auditory stimuli. Misophonia clinical presentations are relatively complex and reflect individualized experiences across clinical populations. Like some overlapping neurodevelopmental and neuropsychiatric disorders, misophonia is potentially syndromic where symptom patterns rather than any one symptom contribute to diagnosis. The current study conducted an exploratory k-means cluster analysis to evaluate symptom presentation in a non-clinical sample of young adult undergraduate students (N = 343). Individuals participated in a self-report spectrum characteristics survey indexing misophonia, tinnitus severity, sensory hypersensitivity, and social and psychiatric symptoms. Results supported a three-cluster solution that split participants on symptom presentation: cluster 1 presented with more severe misophonia symptoms but few overlapping formally diagnosed psychiatric co-occurring conditions; cluster 3 was characterized by a more nuanced clinical presentation of misophonia with broad-band sensory hypersensitivities, tinnitus, and increased incidence of social processing and psychiatric symptoms, and cluster 2 was relatively unaffected by misophonia or other sensitivities. Clustering results illustrate the spectrum characteristics of misophonia where symptom patterns range from more "pure" form misophonia to presentations that involve more broad-range sensory-related and psychiatric symptoms. Subgroups of individuals with misophonia may characterize differential neuropsychiatric risk patterns and stem from potentially different causative factors, highlighting the importance of exploring misophonia as a multidimensional condition of complex etiology.

Misophonia: An Underrecognized Disease in Pediatric Patients.

Ear, nose, & throat journal [Epub ahead of print].

Misophonia is a chronic condition in which patients experience a strong negative, emotional, or psychologic reaction to specific sounds. These sounds cause the individual to have a sudden, uncontrolled, and disproportionate negative reaction affecting their daily activities. The literature describes several cases of misophonia in the adult population; however, only 2 pediatric case studies are reported. Herein, we present 2 additional cases. An exaggerated response to an auditory stimulus is observed in other disorders such as tinnitus, hyperacusis, migraines, and many psychiatric disorders. Sound aversion has a broad differential diagnosis and may require visits to numerous specialists, placing strain on the patient and the healthcare system. Furthermore, misophonia is underdiagnosed in the pediatric population as it requires self-reporting of symptoms. The pathophysiology, prevalence, and treatment of misophonia continue to be relatively unknown. We attempt to highlight this rarely reported pediatric diagnosis and elaborate on its clinical presentation to increase awareness among otolaryngologists.

A Feminist Ethic of Care for the Veterinary Profession.

Frontiers in veterinary science, 9:795628.

I can still see the dog's face as its eyes connected with mine, framed by the black bin bag it had been carried in. I can still hear the clicking sound, louder than the animal's shrill cries, made by a mass of maggots moving against one another beneath the dogs matted fur, moistened by fluids leaking from its damaged flesh. My hands were shaking with panic and rage and I could hardly draw up the euthatal into the syringe quickly enough. I wanted to put an end to this, immediately. As the lethal fluid flowed into the tiny vein the dog's body finally relaxed. At my hand, like so many others, she had ceased to exist. Through the window I could see her owners waiting outside in the sunshine to pay me and I thought about the silky feel of the fur which covered an expensively shaped head. I knew this dog was loved once. This paper develops two neglected areas of veterinary thought; anthropological studies of the veterinary profession and feminist care approaches in veterinary ethics. I argue that the development of veterinary anthropology is crucial to advancing our understanding of veterinary lived experiences, through highlighting the previously under acknowledged emotional, relational and contextual realities of veterinary practice. I further propose that an ethic of care for the veterinary profession, which meaningfully connects with veterinary lived experiences, may provide a valuable approach through which to further develop veterinary ethical thinking. I share an autoethnographic account of a difficult veterinary encounter, which I then analyse using a novel feminist care approach. Through analyses centered on both emotional and relational aspects of veterinary care, I challenge the boundaries of traditional veterinary ethical approaches in terms of the scope, scale and complexity of veterinary ethical decision making. I describe the concept of emotional sponge work in veterinary practice and outline its potential impact for advancing understanding of both veterinary well-being and the profession's societal role. Finally, I propose that a feminist ethic of care might provide a framework for redefining the focus of veterinary professional responsibility, beyond animal health and toward the maintenance of healthy relationships between humans and animals.

Consensus Definition of Misophonia: A Delphi Study.

Frontiers in neuroscience, 16:841816.

Misophonia is a disorder of decreased tolerance to specific sounds or their associated stimuli that has been characterized using different language and methodologies. The absence of a common understanding or foundational definition of misophonia hinders progress in research to understand the disorder and develop effective treatments for individuals suffering from misophonia. From June 2020 through January 2021, the authors conducted a study to determine whether a committee of experts with diverse expertise related to misophonia could develop a consensus definition of misophonia. An expert committee used a modified Delphi method to evaluate candidate definitional statements that were identified through a systematic review of the published literature. Over four rounds of iterative voting, revision, and exclusion, the committee made decisions to include, exclude, or revise these statements in the definition based on the currently available scientific and clinical evidence. A definitional statement was included in the final definition only after reaching consensus at 80% or more of the committee agreeing with its premise and phrasing. The results of this rigorous consensus-building process were compiled into a final definition of misophonia that is presented here. This definition will serve as an important step to bring cohesion to the growing field of researchers and clinicians who seek to better understand and support individuals experiencing misophonia.

Attention, flexibility, and imagery in misophonia: Does attention exacerbate everyday disliking of sound?.

Journal of clinical and experimental neuropsychology [Epub ahead of print].

INTRODUCTION: Misophonia is an unusually strong aversion to everyday sounds, such as chewing, crunching, or breathing. Here, we ask whether misophonia might be tied to an unusual profile of attention (and related traits), which serves to substantially heighten an otherwise everyday disliking of sounds.

METHODS: In Study 1, we tested 136 misophonics and 203 non-misophonics on self-report measures of attention to detail, cognitive inflexibility, and auditory imagery, as well as collecting details about their misophonia. In Study 2, we administered the Embedded Figures task to 20 misophonics and 36 non-misophonics.

RESULTS: We first showed that the degree to which sounds trigger misophonia reflects the pattern by which they are (more mildly) disliked by everyone. This suggests that misophonia is scaffolded onto existing mechanisms rather than qualitatively different ones. Compared to non-misophonics, we also found that misophonics self-reported greater attention to detail, cognitive inflexibility, and auditory imagery. As their symptoms worsen, they also become more accurate in an attentional task (Embedded Figures).

CONCLUSIONS: Our findings provide a better understanding of misophonia and support the hypothesis that dispositional traits of attention to detail may be key to elevating everyday disliking of sound into the more troubling aversions of misophonia.

Psychiatric and audiologic features of misophonia: Use of a clinical control group with auditory over-responsivity.

Journal of psychosomatic research, 156:110777 pii:S0022-3999(22)00062-9 [Epub ahead of print].

OBJECTIVE: This cross-sectional study was designed to add to the emerging empirical literature characterizing the psychiatric and audiologic features of misophonia. Because most research to date has not compared misophonia to clinical control groups, the present study used both participants who did not report any sound intolerance problems and a clinical control group of participants with auditory over-responsivity not formally meeting criteria for a diagnosis of misophonia using proposed diagnostic criteria by Schroeder et al. (2013). Severity of misophonia symptoms, frequency of current or lifetime psychiatric disorders, loudness discomfort, and hearing loss were compared across groups.

METHODS: Structured interviews, questionnaires, and objective measures of audiologic functioning were administered to a sample of adult participants (N = 156). Measures included an interviewer-rated diagnostic assessment of misophonia, the MisoQuest, (Siepsiak et al., 2020), M.I.N·I (Sheehan et al., 1998), loudness discomfort level (LDL), and hearing loss (PTA).

RESULTS: Group differences in misophonia symptom severity among all three groups were observed: FWelch (2,50.57) = 149.92, p < .001, n2 = 0.64, validating group assignment. Psychiatric disorders were significantly more frequent in the misophonia group (71%) than in the auditory over-responsivity group (40%) and control group (40%): X2 (2, N = 142) = 14.3; p = .001; V = 0.317. A wide range of psychiatric disorders were observed in the misophonia group, (e.g., major depressive episode, suicidality and panic disorder were the most common). There were no significant differences between groups with regards to audiologic functioning.

CONCLUSION: Misophonia co-occurs with a variety of psychiatric disorders but does not appear to be associated with loudness discomfort or hearing impairments.

The reliability and validity of decreased sound tolerance scale-screening.

Brazilian journal of otorhinolaryngology pii:S1808-8694(21)00212-3 [Epub ahead of print].

OBJECTIVES: Decreased Sound Tolerance (DST) is a negative reaction to a sound that does not cause any reaction in an individual with normal hearing. DST's subclasses include hyperacusis, phonophobia, and misophonia, which are distinct and have therapy variations. There is no diagnostic method or scale that distinguishes them in the literature. This study's purpose was to develop a screening scale that distinguishes these three DSTs.

METHODS: The study comprised 257 willing participants with normal hearing. Cronbach alpha coefficient, item-total correlation, and item differentiation of the Decreased Sound Tolerance Scale-Screening (DSTS-S) were evaluated. Structural validity of DSTS-S was performed by Varimax rotation with Kaiser normalization using Explanatory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA) was performed to assess its structural compatibility. The scale's total scores from each section were compared using the Mann-Whitney U test in symptom (+) and symptom (-) participants.

RESULTS: The Cronbach alpha value for hyperacusis, phonophobia, and misophonia sections of DSTS-S was calculated as 0.881, 0.775, and 0.938, respectively. The difference between the independent samplet-test and the variables was statistically significant (p < 0.01). The Mann-Whitney U test showed a significant difference between the median values of the total groups' scores with and without hyperacusis, phonophobia, and misophonia (HTS, PTS, and MTS, respectively) (p < 0.05). Evaluation by ROC analysis showed that hyperacusis was useful in predicting the presence of hyperacusis, phonophobia was useful in predicting the presence of phonophobia, and misophonia was useful in predicting the presence of misophonia (p < 0.001). Hyperacusis and misophonia sections showed high reliability, and phonophobia section showed a moderately reliable level. The Kappa test showed that the compatibility between test-retest for the total scores was statistically significant (p < 0.001).

CONCLUSION: The study's results indicated that DSTS-S is a valid and reliable scale for identifying subtypes/problems/classes of decreased sound tolerance.

Examining emotional functioning in misophonia: The role of affective instability and difficulties with emotion regulation.

PloS one, 17(2):e0263230 pii:PONE-D-21-04070.

Misophonia is a newly described condition characterized by sensory and emotional reactivity (e.g., anxiety, anger, disgust) to repetitive, pattern-based sounds (e.g., throat clearing, chewing, slurping). Individuals with misophonia report significant functional impairment and interpersonal distress. Growing research indicates ineffective coping and emotional functioning broadly (e.g., affective lability, difficulties with emotion regulation) are central to the clinical presentation and severity of misophonia. Preliminary evidence suggests an association between negative emotionality and deficits in emotion regulation in misophonia. Still, little is known about (a) the relationships among specific components of emotional functioning (e.g., emotion regulation, affective lability) with misophonia, and (b) which component(s) of misophonia (e.g., noise frequency, emotional and behavioral responses, impairment) are associated with emotional functioning. Further, despite evidence that mood and anxiety disorders co-occur with misophonia, investigation thus far has not controlled for depression and anxiety symptoms. Examination of these relationships will help inform treatment development for misophonia. The present study begins to disambiguate the relationships among affective lability, difficulties with emotion regulation, and components of misophonia. A sample of 297 participants completed questionnaires assessing misophonia, emotional functioning, depression, anxiety, and COVID-19 impact. Findings indicated that misophonia severity was positively associated with each of these constructs with small to medium effect sizes. When controlling for depression, anxiety, and COVID-19 impact, results from this preliminary study suggest that (a) difficulties with emotion regulation may be correlated with misophonia severity, and (b) misophonic responses, not number of triggers or perceived severity, are associated with difficulties with emotion regulation. Overall, these findings begin to suggest that emotion regulation is important to our understanding the risk factors and treatment targets for misophonia.

Online Emotion Regulation for an Adolescent With Misophonia: A Case Study.

Journal of cognitive psychotherapy pii:JCP-2021-0015 [Epub ahead of print].

Misophonia is a novel diagnosis characterised by extreme and uncontrollable autonomic reactions and emotional responses to selective auditory stimuli, which can significantly impair an individual's daily life. No agreed diagnostic criteria are currently available for misophonia, and any therapeutic guidance is yet to be formalised. In this case study, a tailored psychological intervention based on the cognitive model and developed around emotion regulation principles and techniques was adopted to treat misophonia in a 16-year-old female from the United Kingdom. The treatment lasted for 15 weeks and was delivered online due to the ongoing COVID-19 social distancing regulations. The results showed that the intervention was feasible and acceptable, and effective at reducing levels of misophonic symptoms from severe to moderate/mild while also improving emotion dysregulation and overall anxiety and depression. Particular improvements were observed for specific skills such as acceptance and awareness of emotional responses and increased access to emotion regulation strategies. These findings also translated into a number of reported daily life improvements in the client's psychological and social well-being. As the current evidence base on misophonia continues to develop, more methodologically rigorous research is warranted to build on the present findings and inform the adoption of further psychotherapeutic approaches to treat this new condition.

β-Blockers for the Treatment of Misophonia and Misokinesia.

Clinical neuropharmacology, 45(1):13-14.

ABSTRACT: Misophonia is an adverse physical and emotional reaction to certain repetitive trigger sounds, usually generated by other people. Misokinesia refers to visual triggers that are sometimes (but not always) related to trigger sounds. Despite how common and disabling these conditions can be, medication treatment of misophonia and misokinesia is largely unexplored. We present the first case of using a β-blocker (propranolol) to successfully treat a patient experiencing misophonia and misokinesia. A moderate dose (60 mg) of propranolol completely eliminated multiple auditory and visual trigger symptoms related to other people eating. His trigger response symptoms included overwhelming negative emotions and prominent sympathetic overactivity (fight-or-flight response). These symptoms were so severe that he had avoided most meals with friends and family for the past several years. Propranolol eliminated the emotional and physiological effects of both the auditory and visual triggers, with an Amsterdam Misophonia Scale score reduction from 15 to 2. This enabled him to resume eating meals with family and friends with no distress. The medication was well tolerated. In summary, we report the novel finding that β-blockers were markedly effective at treating the physical and emotional symptoms of a patient with misophonia and misokinesia. This suggests a novel treatment approach for these conditions.

Family Accommodation of Symptoms in Adults With Obsessive-Compulsive Disorder: Factor Structure and Usefulness of the Family Accommodation Scale for OCD-Patient Version.

Journal of psychiatric practice, 28(1):36-47 pii:00131746-202201000-00005.

For individuals with obsessive-compulsive disorder (OCD), family accommodation of symptoms, such as over-reassurance, participation in rituals, or facilitation of avoidance, is one of the key factors associated with symptom severity, maintenance, and related impairment. Most studies have assessed accommodation behaviors based on reports from family members or other loved ones. Recently, a patient-rated questionnaire, the Family Accommodation Scale for OCD-Patient Version (FAS-PV) was developed to assess family accommodation from the patient's perspective. This study investigated the factor structure of the FAS-PV and clinical variables associated with patient-reported family accommodation in a sample of 151 treatment-seeking adults with OCD. A confirmatory factor analysis suggested that a 4-factor model best characterized the scale, with the following factors: (1) participation in symptoms, (2) avoidance of OCD triggers, (3) taking on responsibilities, and (4) modifying responsibilities. Internal consistency was high for the total score and for scores on the 4 subscales of the FAS-PV. Approximately 87% of the sample reported accommodation behaviors at some level. Family accommodation was positively correlated with OCD symptom severity and functional disability, and partially mediated the associations between these 2 factors, so that greater OCD severity was associated with greater accommodation, which, in turn, was associated with greater disability. Our findings parallel those of studies that have employed other versions of the FAS and suggest that the FAS-PV is a useful tool for assessing family accommodation of OCD symptoms from the patient's perspective.

Item Response Theory Investigation of Misophonia Auditory Triggers.

Audiology research, 11(4):567-581 pii:audiolres11040051.

Misophonia is characterised by a low tolerance for day-to-day sounds, causing intense negative affect. This study conducts an in-depth investigation of 35 misophonia triggers. A sample of 613 individuals who identify as experiencing misophonia and 202 individuals from the general population completed self-report measures. Using contemporary psychometric methods, we studied the triggers in terms of internal consistency, stability in time, precision, severity, discrimination ability, and information. Three dimensions of sensitivity were identified, namely, to eating sounds, to nose/throat sounds, and to general environmental sounds. The most informative and discriminative triggers belonged to the eating sounds. Participants identifying with having misophonia had also significantly increased odds to endorse eating sounds as auditory triggers than others. This study highlights the central role of eating sounds in this phenomenon and finds that different triggers are endorsed by those with more severe sound sensitivities than those with low sensitivity.

Development and Initial Validation of the Duke Misophonia Questionnaire.

Frontiers in psychology, 12:709928.

Misophonia is characterized by decreased tolerance and accompanying defensive motivational system responding to certain aversive sounds and contextual cues associated with such stimuli, typically repetitive oral (e. g., eating sounds) or nasal (e.g., breathing sounds) stimuli. Responses elicit significant psychological distress and impairment in functioning, and include acute increases in (a) negative affect (e.g., anger, anxiety, and disgust), (b) physiological arousal (e.g., sympathetic nervous system activation), and (c) overt behavior (e.g., escape behavior and verbal aggression toward individuals generating triggers). A major barrier to research and treatment of misophonia is the lack of rigorously validated assessment measures. As such, the primary purpose of this study was to develop and psychometrically validate a self-report measure of misophonia, the Duke Misophonia Questionnaire (DMQ). There were two phases of measure development. In Phase 1, items were generated and iteratively refined from a combination of the scientific literature and qualitative feedback from misophonia sufferers, their family members, and professional experts. In Phase 2, a large community sample of adults (n = 424) completed DMQ candidate items and other measures needed for psychometric analyses. A series of iterative analytic procedures (e.g., factor analyses and IRT) were used to derive final DMQ items and scales. The final DMQ has 86 items and includes subscales: (1) Trigger frequency (16 items), (2) Affective Responses (5 items), (3) Physiological Responses (8 items), (4) Cognitive Responses (10 items), (5) Coping Before (6 items), (6) Coping During (10 items), (7) Coping After (5 items), (8) Impairment (12 items), and Beliefs (14 items). Composite scales were derived for overall Symptom Severity (combined Affective, Physiological, and Cognitive subscales) and Coping (combined the three Coping subscales). Depending on the needs of researchers or clinicians, the DMQ may be use in full form, individual subscales, or with the derived composite scales.

EMDR therapy for misophonia: a pilot study of case series.

European journal of psychotraumatology, 12(1):1968613 pii:1968613.

Background: Misophonia is a disorder in which patients suffer from anger or disgust when confronted with specific sounds such as loud chewing or breathing, causing avoidance of cue-related situations resulting in significant functional impairment. Though the first treatment studies with cognitive behavioural therapy (CBT) showed promising results, an average of 50% of the patients has not improved much clinically.

Objective: The aim of this pilot study was to assess the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy as a trauma-focused approach in treating misophonia symptoms.

Method: A sample of 10 adult participants with misophonia was studied at the outpatient clinic of the Academic Medical Center in Amsterdam. Participants were either on the waiting list for CBT or non-responders to CBT. EMDR was focused on misophonia-related emotionally disturbing memories and delivered in a mean of 2.6 sessions of 60-90 minutes. Pre- and post-treatment self-assessed ratings of misophonia symptoms (AMISOS-R, primary outcome), of general psychopathology (SCL-90-R) and of quality of life (SDS) were administered. The co-primary outcome was the Clinical Global Impression Improvement scale (CGI-I).

Results: A paired t-test (n = 8) showed improvement on the primary outcome (-6.14 [MD], 5.34 [SD]) on the AMISOS-R (P = .023). Three of the eight patients showed clinically significant improvement measured with the CGI-I. No significant effect on secondary outcomes was found.

Conclusions: These preliminary results suggest that EMDR therapy focused on emotionally disturbing misophonia-related memories can reduce misophonia symptoms. RCTs with sufficient sample sizes are required to firmly establish the value of EMDR therapy for misophonia.

Validation of the Rage Attack Questionnaire-Revised (RAQ-R) in a Mixed Psychiatric Population.

Frontiers in psychiatry, 12:724802.

Rage Attacks (RA) represent a clinically relevant symptom in patients with different psychiatric disorders. However, only recently the Rage Attack Questionnaire Revised (RAQ-R, 22 items, range, 0-66) has been developed as a new instrument for the assessment of RA. This study aimed to validate the RAQ-R in a large mixed psychiatric and psychosomatic sample. We tested internal consistency, convergent and discriminant validity as well as factor structure. In order to further explore the relationship of RA to other psychiatric symptoms, we calculated Pearson correlations between the RAQ-R and several other self-assessments including measurements for general psychological distress, quality of life, depression, anxiety, attention deficit/hyperactivity disorder (ADHD), impulsivity, and self-regulation abilities. Most relevant predictors of RA were examined in a multiple regression with stepwise elimination. In order to assess the manifestation of RA in different psychiatric disorders, group differences between diagnostic categories and healthy controls were calculated. Additionally, psychiatric patients were compared to patients with Tourette syndrome along RAQ-R scores. Data from healthy subjects and patients with Tourette syndrome were obtained from a previous study of our group. In this study, we included 156 patients with a wide and typical spectrum of psychiatric diseases. The RAQ-R was found to have excellent internal consistency and strong construct validity in this sample (Cronbach's α = 0.97, Average Variance Extracted = 0.58). Thus, the RAQ-R was shown to be a psychometrically sound assessment of RA in patients with different psychiatric disorders. Close constructs to RA were found to be aggression and hostility (r = 0.68) as well as low frustration tolerance and impulse control (r = 0.69). Compared to healthy controls, RA were significantly more common in the psychiatric sample (p < 0.001). More specifically, RAQ-R scores in all diagnostic categories assessed were higher compared to controls. Highest scores and effect sizes were found in patients with ADHD and borderline personality disorder (p < 0.001). Our results suggest that RA are a common and relevant symptom in many psychiatric disorders. As depression and RA showed only a moderate relation, RA should be distinguished from the concept of anger attacks, which are described as a core symptom of depression.

Family Experiences of Decreased Sound Tolerance in ASD.

Journal of autism and developmental disorders [Epub ahead of print].

Decreased sound tolerance (DST) is the most common sensory difficulty experienced by autistic individuals. Parents of 88 autistic children and young adults between the ages of 3 and 30 described coping strategies and physical and emotional responses used to deal with distressing sounds, and their impact on daily activities. Loud, sudden, and high-pitched sounds were most commonly endorsed as distressing, most often causing autistic children and young adults to cover their ears or yell, while producing stress, irritation, fear, and anxiety. Parents reported warning their child, providing breaks, or avoiding noisy settings as the most used coping strategies. Overall, findings indicate that DST leads to fewer opportunities for autistic children and young adults to participate at home, at school, and in the community. Further, results suggest hyperacusis, misophonia, and phonophobia, subtypes of DST, are present in autistic children and young adults.

White matter abnormalities in misophonia.

NeuroImage. Clinical, 32:102787 pii:S2213-1582(21)00231-X [Epub ahead of print].

Misophonia is a condition in which specific ordinary sounds provoke disproportionately strong negative affect and physiological arousal. Evidence for neurobiological abnormalities underlying misophonia is scarce. Since many psychiatric disorders show white matter (WM) abnormalities, we tested for both macro and micro-structural WM differences between misophonia patients and healthy controls. We collected T1-weighted and diffusion-weighted magnetic resonance images from 24 patients and 25 matched controls. We tested for group differences in WM volume using whole-brain voxel-based morphometry and used the significant voxels from this analysis as seeds for probabilistic tractography. After calculation of diffusion tensors, we compared group means for fractional anisotropy, mean diffusivity, and directional diffusivities, and applied tract-based spatial statistics for voxel-wise comparison. Compared to controls, patients had greater left-hemispheric WM volumes in the inferior fronto-occipital fasciculus, anterior thalamic radiation, and body of the corpus callosum connecting bilateral superior frontal gyri. Patients also had lower averaged radial and mean diffusivities and voxel-wise comparison indicated large and widespread clusters of lower mean diffusivity. We found both macro and microstructural WM abnormalities in our misophonia sample, suggesting misophonia symptomatology is associated with WM alterations. These biological alterations may be related to differences in social-emotional processing, particularly recognition of facial affect, and to attention for affective information.

Explainable AI-based clinical decision support system for hearing disorders.

AMIA ... Annual Symposium proceedings. AMIA Symposium, 2021:595-604.

In clinical system design, human-computer interaction and explainability are important topics of research. Clinical systems need to provide users with not only results but also an account of their behaviors. In this research, we propose a knowledge-based clinical decision support system (CDSS) for the diagnosis and therapy of hearing disorders, such as tinnitus, hyperacusis, and misophonia. Our prototype eTRT system offers an explainable output that we expect to increase its trustworthiness and acceptance in the clinical setting. Within this paper, we: (1) present the problem area of tinnitus and its treatment; (2) describe our data-driven approach based on machine learning, such as association- and action rule discovery; (3) present the evaluation results from the inference on the extracted rule-based knowledge and chosen test cases of patients; (4) discuss advantages of explainable output incorporated into a graphical user interface; (5) conclude with the results achieved and directions for future work.

The development and validation of the Misophonia response scale.

Journal of psychosomatic research, 149:110587.

OBJECTIVE: Most current Misophonia scales are not validated, do not include both emotional and physiological responses to triggers, and/or focus only on auditory triggers. This research aimed to develop and validate a measure of the magnitude of the Misophonic response that addressed these omissions.

METHOD: Three studies were carried out with individuals with self-diagnosed Misophonia. In study 1, expert opinion and participants commented on initial items to determine both face and content validity. In study 2, scale structure, reliability, and convergent and discriminant validity were determined using correlations, principal component analysis (PCA), and reliability analysis. In study 3, factor structure was confirmed in another sample of participants using confirmatory factor analysis (CFA).

RESULTS: The final 22-item scale assesses the magnitude of responses to triggers across any sensory modality. There are three subscales (emotional, physiological, and participation in life), with three additional items measuring frequency of triggers, avoidance of triggers, and time taken to recover from the triggers. The final scale showed suitable discriminant and convergent validity, with good internal consistency (Cronbach's alphas range 0.77 to 0.89). The three-component solution extracted using PCA explained 53.97% of variance, with all items loading between 0.45 and 0.84. The structure was confirmed with CFA (χ2 = 269.01, p < .001; CFI = 0.96; TLI = 0.96 and RMSEA = 0.045 (CI 0.037-0.053).

CONCLUSION: The Misophonia Response Scale, which is valid and reliable, will facilitate understanding of Misophonia as it is short and easy to use for self-report in research.

Evaluation and Management of Misophonia Using a Hybrid Telecare Approach: A Case Report.

Seminars in hearing, 42(2):123-135.

Decreased sound tolerance (DST) is a negative reaction to environmental sounds and is estimated to affect 3.5% of the population. This case report presents the evaluation and management of an adult female with severe, longstanding misophonia. Her evaluation included comprehensive audiometric testing (including uncomfortable loudness levels) and a detailed assessment of the impact of DST on her life. She enrolled in tinnitus retraining therapy and began receiving treatment aiming to facilitate habituation of bothersome environmental sounds. This case was complicated by the advent of the coronavirus disease 2019 (COVID-19) pandemic and a telemedicine hybrid approach was employed to increase access to audiologic care. Using this structure, some appointments occurred in person in the clinic and others occurred via a telemedicine video visit format. Telemedicine video visits facilitated in-depth discussions, afforded the opportunity to answer questions, and provided the option of cloud-based remote programming of on-ear devices. Future care will continue to employ a hybrid approach.

Exposure Therapy for Misophonia: Concepts and Procedures.

Journal of cognitive psychotherapy, 35(3):156-166.

Misophonia, a condition marked by extreme intolerance to certain classes of sounds (e.g., respiratory or gustatory noises), has recently attracted increased research attention. As yet there are no evidence-based treatments, although some promising options are under empirical consideration. This paper presents a stress management and exposure therapy-based treatment protocol for adults with misophonia. The protocol details considerations specific to exposure therapy for misophonia, including unique considerations for developing hierarchies and example misophonia exposure exercises and exposure homework. Stress management approaches employed to facilitate engagement with exposure are also described. Two case examples are included, which illustrate the application of the misophonia treatment protocol. The first case describes treatment for a client whose misophonia symptoms are the primary focus and the second case describes treatment for a client whose misophonia symptoms are secondary to relationship difficulties. This protocol can be used to stimulate further treatment research for misophonia and guide treatment for individuals with misophonia.

The prevalence and characteristics of misophonia in Ankara, Turkey: population-based study.

BJPsych open, 7(5):e144.

BACKGROUND: Misophonia is defined as significant distress (anger, distress or disgust) when exposed to certain sounds that would not affect most people, such as lip smacking or gum chewing. Although misophonia is common, the aetiology, prevalence and effective treatments are largely unknown.

AIMS: Based on our proposed diagnostic criteria, we examined the prevalence of misophonia and its relationship with clinical and demographic variables in a large representative population sample.

METHOD: We used a household sample (N = 541) of all residents aged >15 years, living in 300 homes randomly selected in Ankara city centre, Turkey. All participants were assessed at their homes by trained interviewers, for sociodemographic variables, misophonic sounds and related factors, using a semi-structured interview (the Misophonia Interview Schedule) developed for the current research.

RESULTS: The current misophonia diagnosis prevalence was 12.8% (n = 69 of 541), although 427 (78.9%) participants reported at least one sound that was distressing. The mean number of misophonic sounds was 8.6 (s.d. 8.9, range 0-44); the figure was 17.6 in those with misophonia compared with 7.3 in those without misophonia. Of those with misophonia, only 5.8% contacted services for their condition. Predictors of misophonia diagnosis included younger age, family history of misophonia and previous contact with mental health services.

CONCLUSIONS: Our study showed that misophonia is common in the general population, may cause significant disruption in daily life and is undertreated. Although more evidence is needed to classify misophonia as a psychiatric disorder, our findings support others who claim that the condition belongs to the group of mental disorders.

Tinnitus, Hyperacusis, Otalgia, and Hearing Loss.

Continuum (Minneapolis, Minn.), 27(2):491-525.

PURPOSE OF REVIEW: This article reviews the causes of tinnitus, hyperacusis, and otalgia, as well as hearing loss relevant for clinicians in the field of neurology.

RECENT FINDINGS: Important causes of unilateral and bilateral tinnitus are discussed, including those that are treatable or caused by serious structural or vascular causes. Concepts of hyperacusis and misophonia are covered, along with various types of neurologic disorders that can lead to pain in the ear. Hearing loss is common but not always purely otologic.

SUMMARY: Tinnitus and hearing loss are common symptoms that are sometimes related to a primary neurologic disorder. This review, tailored to neurologists who care for patients who may be referred to or encountered in neurology practice, provides information on hearing disorders, how to recognize when a neurologic process may be involved, and when to refer to otolaryngology or other specialists.

Investigating tinnitus subgroups based on hearing-related difficulties.

International journal of clinical practice, 75(10):e14684.

PURPOSE: Meaningfully grouping individuals with tinnitus who share a common characteristics (ie, subgrouping, phenotyping) may help tailor interventions to certain tinnitus subgroups and hence reduce outcome variability. The purpose of this study was to test if the presence of tinnitus subgroups are discernible based on hearing-related comorbidities, and to identify predictors of tinnitus severity for each subgroup identified.

METHODS: An exploratory cross-sectional study was used. The study was nested within an online survey distributed worldwide to investigate tinnitus experiences during the COVID-19 pandemic. The main outcome measure was the tinnitus Handicap Inventory- Screening Version.

RESULTS: From the 3400 respondents, 2980 were eligible adults with tinnitus with an average age of 58 years (SD = 14.7) and 49% (n = 1457) being female. A three-cluster solution identified distinct subgroups, namely, those with tinnitus-only (n = 1306; 44%), those presenting with tinnitus, hyperacusis, hearing loss and/or misophonia (n = 795; 27%), and those with tinnitus and hearing loss (n = 879; 29%). Those with tinnitus and hyperacusis reported the highest tinnitus severity (M = 20.3; SD = 10.5) and those with tinnitus and no hearing loss had the lowest tinnitus severity (M = 15.7; SD = 10.4). Younger age and the presence of mental health problems predicted greater tinnitus severity for all groups (β ≤ -0.1, P ≤ .016).

CONCLUSION: Further exploration of these potential subtypes are needed in both further research and clinical practice by initially triaging tinnitus patients prior to their clinical appointments based on the presence of hearing-related comorbidities. Unique management pathways and interventions could be tailored for each tinnitus subgroup.

Sounds of Silence in Times of COVID-19: Distress and Loss of Cardiac Coherence in People With Misophonia Caused by Real, Imagined or Evoked Triggering Sounds.

Frontiers in psychiatry, 12:638949.

The extreme, unprecedented situations in the current COVID-19 pandemic are risk factors for psychosocial stress for the entire population. However, strict confinement had a particular impact on people suffering from misophonia and their families. Misophonia is a condition in which hearing certain sounds triggers intense anger, disgust and even severe autonomic nervous system responses. This prospective cohort study examined the impact of strict confinement (Spain, March 14-June 21, 2020) on a sample of 24 people (16 women and eight men) who had been diagnosed with moderate to extreme misophonia and were regularly attending a medical psychology center in Barcelona. The 3-month period of confinement caused general emotional maladjustment, distress, and a transitory crisis. Long-term biomonitoring of their heart variability rate (HRV) enabled to identify a significant increase in physiological arousal after the confinement period, which had already been recorded in a loss of cardiac coherence under basal rest/relaxation conditions. Certain auditory stimuli triggered adverse responses, lowered HRV scores, and an increased stress level and heart rate. Loss of cardiac coherence in their responses to these auditory stimuli (triggering mouth, nose and other sounds), as well as to non-triggering mouth, nose and other sounds was increased when compared to two assessments performed during the previous year. Despite the limited sample size, sex differences were observed in the incidence. Loss of cardiac coherence worsened with the severity of the misophonia. Most importantly, imagined or evoked triggering sounds, as well as real ones, were enough to cause the aversive responses, as displayed by the increased loss of cardiac coherence with respect to the at-rest basal level. A semi-structured interview revealed the exceptional nature of the situations, increased hyper-sensorial sensitivity, fear of being infected with or dying from COVID-19, the patients' coping strategies, and the difficulties and constraints they faced. Finally, the article gives recommendations for better management of misophonia. Improved knowledge of this disorder would help address the current lack of health and social care, hopefully preventing this shortfall's impact on social and affective relationships, which are particulary important for well-being now and in the coming periods of physical distancing measures.

Structural and functional brain abnormalities in misophonia.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology, 52:62-71 pii:S0924-977X(21)00244-3 [Epub ahead of print].

Misophonia is a newly described condition in which specific ordinary sounds provoke disproportionately strong negative affect. Since evidence for neurobiological abnormalities underlying misophonia is scarce, we tested whether misophonia patients differed from healthy controls in grey matter volumes and resting-state functional connectivity. We collected structural magnetic resonance imaging and resting-state functional magnetic resonance imaging data from 24 misophonia patients and 25 matched controls. Compared to controls, voxel-based morphometry showed larger right amygdala volume in misophonia patients. Follow-up seed-based functional connectivity analysis of the amygdala showed a different pattern of connectivity with the cerebellum, driven by greater connectivity with the left amygdala. Additional data-driven independent component analysis showed greater connectivity within lateral occipital cortices and fusiform gyri in the ventral attention network. We propose that the amygdala enlargement may be associated with heightened emotional reactivity in misophonia. The higher connectivity between left amygdala and cerebellum might be linked to a tendency to exhibit reflex-like physical reactions to triggers. Higher attention network connectivity may reflect sensory enhancement of visual triggers or visual imagery related to trigger sounds. In sum, we found structural and functional abnormalities which implicate dysfunction of emotional and attentional systems in misophonia.

Misophonia Successfully Treated of With Fluoxetine: A Case Report.

Clinical neuropharmacology, 44(5):191-192.

OBJECTIVE: A large number of people experience misophonia. In 2013, the Amsterdam Study Group recommended diagnostic criteria for misophonia. However, misophonia is not yet included in the Diagnostic and Statistical Manual of Mental Disorders. This report is the first report on drug use that directly affects misophonia and demonstrates a 14-year-old adolescent girl with misophonia successfully treated with fluoxetine.

METHODS: The patient's misophonia symptoms had been continuing for approximately 2 years, and her quality of life was significantly reduced. Psychotherapy conditions could not be applied, and fluoxetine 10 mg/d was started and increased to 20 mg/d after a week. At the second-month follow-up, because of partial improvement, fluoxetine dose was increased to 30 mg/d.

RESULTS: At the fourth-month follow-up, there was a 40% decrease in Amsterdam Misophonia Scale score with a 70% decrease in the children's global assessment scale scores. By the 16th week, the overall functionality level was good at the end.

CONCLUSIONS: Fluoxetine may be used as an effective drug in the treatment of misophonia.

["Ear rage": misophonia : Review and current state of knowledge].

HNO [Epub ahead of print].

Misophonia is a devastating disorder. It is known as an affective sound-processing disorder characterized by the experience of strong negative emotions (e.g., anger, distress) in response to human sounds such as eating/swallowing/breathing. Other sounds produced by humans but not directly by human bodies can also be misophonic triggers (e.g. pen clicking) or environmental sounds (animal sounds/sounds of machines). The type of aversive triggers is individual. The reaction to trigger sounds can depend on many factors, such as assessment of the sound, personal experience, social context or psychological profile. However, there is currently no consensus in defining misophonia. Misophonia is also not yet classified by any official diagnostic system, although it seems to be a separate disorder. There are also associations with other disorders such as activity disorders, tinnitus, hyperacusis, and autism spectrum disorders. In 2013, the first definition criteria were published for the diagnosis of misophonia. Specifically, fMRI showed abnormal activation of the anterior insular cortex (AIC) and other brain areas responsible for the processing and regulation of emotions. To date, no randomized controlled trials evaluating treatments have been published. The use of cognitive and behavioral interventions have been reported as well as external sound systems and sound masking systems as known in the tinnitus retraining therapy. Sufferers try to minimize the trigger sounds by wearing ear plugs or music headphones. Otolaryngologists may also encounter patients with symptoms of misophonia, e.g., when hearing screening is requested or advice should be given on different therapeutic options. This report provides an overview of the current state of knowledge in misophonia and its diagnosis and treatment.

Autonomous Sensory Meridian Response self-reporters showed higher scores for cognitive reappraisal as an emotion regulation strategy.

PeerJ, 9:e11474.

Background: Autonomous Sensory Meridian Response (ASMR) describes the experience of a pleasant tingling sensation along the back of the head, accompanied with a feeling of well-being and relaxation, in response to specific audio-visual stimuli, such as whispers, soft sounds, and personal attention. Previous works have assessed individual variations in personality traits associated with ASMR, but no research to date has explored differences in emotion regulation associated with ASMR. This omission occurred even when ASMR, a sensory-emotional experience, has been proposed to be located in a sound sensitivity spectrum as the opposite end of misophonia, a phenomenon associated with difficulties regulating emotions. The present work aimed to assess group differences between ASMR self-reporters and non-ASMR controls associated with emotion regulation strategies.

Methods: We used the validated Spanish version of the Emotion Regulation Questionnaire to assess individual differences in the use of cognitive reappraisal and expressive suppression.

Results: Our results showed that participants who experience ASMR had higher scores in the cognitive reappraisal subscale of the emotion regulation questionnaire than the non-ASMR group.

Conclusions: Individuals who experience ASMR reported higher use of cognitive reevaluation of emotionally arousing situations, suggesting more effectiveness in regulating emotions. Our finding further elucidates individual differences related to this experience, supporting that ASMR is a real psychophysiological phenomenon associated with other psychological constructs and has remarkable consequences in affective/emotional dimensions and general well-being.

What sound sources trigger misophonia? Not just chewing and breathing.

Journal of clinical psychology [Epub ahead of print].

OBJECTIVES: Misophonia is a highly prevalent yet understudied condition characterized by aversion toward particular environmental sounds. Oral/nasal sounds (e.g., chewing, breathing) have been the focus of research, but variable experiences warrant an objective investigation. Experiment 1 asked whether human-produced oral/nasal sounds were more aversive than human-produced nonoral/nasal sounds and non-human/nature sounds. Experiment 2 additionally asked whether machine-learning algorithms could predict the presence and severity of misophonia.

METHOD: Sounds were presented to individuals with misophonia (Exp.1: N = 48, Exp.2: N = 45) and members of the general population (Exp.1: N = 39, Exp.2: N = 61). Aversiveness ratings to each sound were self-reported.

RESULTS: Sounds from all three source categories-not just oral/nasal sounds-were rated as significantly more aversive to individuals with misophonia than controls. Further, modeling all sources classified misophonia with 89% accuracy and significantly predicted misophonia severity (r = 0.75).

CONCLUSIONS: Misophonia should be conceptualized as more than an aversion to oral/nasal sounds, which has implications for future diagnostics and experimental consistency moving forward.

Confinement and the Hatred of Sound in Times of COVID-19: A Molotov Cocktail for People With Misophonia.

Frontiers in psychiatry, 12:627044.

Forced strict confinement to hamper the COVID-19 pandemic seriously affected people suffering from misophonia (M+) and those living with them. Misophonia is a complex neurophysiological and behavioral disorder of multifactorial origin, characterized by an intense physiological and emotional response produced by intolerance to auditory stimuli of the same pattern, regardless of physical properties. The present work studied the secondary impact that strict confinement caused in 342 adults (224 women: 118 men) regularly attending a medical psychological center in Barcelona. Misophonia, usually underdiagnosed, showed a prevalence of 35%, the same for women (37%) than men (31%). A retrospective analysis using a physical-psychological-social inventory of 10 variables evaluated the number of individuals that during confinement and self-confinement (March 11 - June 29, 2020) canceled (mostly M-) and/or requested a therapeutic intervention, the reasons for their request, and the strategies they used to self-manage the situation. Ten main variables indicated that the confinement exponentially increased the effects of misophonia compared with results from the same individuals during the last quarter of 2019. Most people diagnosed with misophonia continued with tele-assistance during the confinement because of this impact's self-concern. Besides the impacts as part of the general population, M+ also developed different symptoms causing significant personal, social, and job/occupational imbalance, as compared to M-. Health, fears, conflicts with neighbors, study-related difficulties were outstanding reasons for consultations. The LSB-50 test for 'Psychological and Psychosomatic Symptoms' applied to M+ revealed the increase of 8 of 9 items of this psychopathological test. Sleep disorders (coronasomnia), hostility, depression, and somatization were more severe than in previous assessments. Women presented the worst psychological and psychosomatic states (eight out of nine, as compared to one out of nine in males). The study unveiled the complex physical-psychological-social burden, the need for dissemination and a gender perspective to understand the secondary impact of COVID-19 pandemic on the mental health of the population with misophonia. The results also show that in this new COVID era people suffering from misophonia need to develop coping strategies addressing modifiable risk and protective factors. They deserve familial/social comprehension, stronger clinical support and a gender medicine perspective.

A psychoacoustic test for misophonia assessment.

Scientific reports, 11(1):11044.

Misophonia is a condition where a strong arousal response is triggered when hearing specific human generated sounds, like chewing, and/or repetitive tapping noises, like pen clicking. It is diagnosed with clinical interviews and questionnaires since no psychoacoustic tools exist to assess its presence. The present study was aimed at developing and testing a new assessment tool for misophonia. The method was inspired by an approach we have recently developed for hyperacusis. It consisted of presenting subjects (n = 253) with misophonic, pleasant, and unpleasant sounds in an online experiment. The task was to rate them on a pleasant to unpleasant visual analog scale. Subjects were labeled as misophonics (n = 78) or controls (n = 55) by using self-report questions and a misophonia questionnaire, the MisoQuest. There was a significant difference between controls and misophonics in the median global rating of misophonic sounds. On the other hand, median global rating of unpleasant, and pleasant sounds did not differ significantly. We selected a subset of the misophonic sounds to form the core discriminant sounds of misophonia (CDSMiso). A metric: the CDS score, was used to quantitatively measure misophonia, both with a global score and with subscores. The latter could specifically quantify aversion towards different sound sources/events, i.e., mouth, breathing/nose, throat, and repetitive sounds. A receiver operating characteristic analysis showed that the method accurately classified subjects with and without misophonia (accuracy = 91%). The present study suggests that the psychoacoustic test we have developed can be used to assess misophonia reliably and quickly.

The Motor Basis for Misophonia.

The Journal of neuroscience : the official journal of the Society for Neuroscience, 41(26):5762-5770.

Misophonia is a common disorder characterized by the experience of strong negative emotions of anger and anxiety in response to certain everyday sounds, such as those generated by other people eating, drinking, and breathing. The commonplace nature of these "trigger" sounds makes misophonia a devastating disorder for sufferers and their families. How such innocuous sounds trigger this response is unknown. Since most trigger sounds are generated by orofacial movements (e.g., chewing) in others, we hypothesized that the mirror neuron system related to orofacial movements could underlie misophonia. We analyzed resting state fMRI (rs-fMRI) connectivity (N = 33, 16 females) and sound-evoked fMRI responses (N = 42, 29 females) in misophonia sufferers and controls. We demonstrate that, compared with controls, the misophonia group show no difference in auditory cortex responses to trigger sounds, but do show: (1) stronger rs-fMRI connectivity between both auditory and visual cortex and the ventral premotor cortex responsible for orofacial movements; (2) stronger functional connectivity between the auditory cortex and orofacial motor area during sound perception in general; and (3) stronger activation of the orofacial motor area, specifically, in response to trigger sounds. Our results support a model of misophonia based on "hyper-mirroring" of the orofacial actions of others with sounds being the "medium" via which action of others is excessively mirrored. Misophonia is therefore not an abreaction to sounds, per se, but a manifestation of activity in parts of the motor system involved in producing those sounds. This new framework to understand misophonia can explain behavioral and emotional responses and has important consequences for devising effective therapies.SIGNIFICANCE STATEMENT Conventionally, misophonia, literally "hatred of sounds" has been considered as a disorder of sound emotion processing, in which "simple" eating and chewing sounds produced by others cause negative emotional responses. Our data provide an alternative but complementary perspective on misophonia that emphasizes the action of the trigger-person rather than the sounds which are a byproduct of that action. Sounds, in this new perspective, are only a "medium" via which action of the triggering-person is mirrored onto the listener. This change in perspective has important consequences for devising therapies and treatment methods for misophonia. It suggests that, instead of focusing on sounds, which many existing therapies do, effective therapies should target the brain representation of movement.

Transdiagnostic cognitive behavioral therapy for misophonia in youth: Methods for a clinical trial and four pilot cases.

Journal of affective disorders, 291:400-408.

BACKGROUND: Misophonia is a condition marked by dysregulated emotions and behaviors in response to trigger sounds, often chewing, breathing, or coughing. Evidence suggests that misophonia develops in adolescence and the emotions and behaviors are a conditioned response to distress, resulting in social avoidance, stress, and family conflict. In addition, co-occurrence with other psychiatric illnesses such as anxiety, OCD, and Tourette syndrome is common. A transdiagnostic cognitive behavioral therapeutic (CBT) approach appears appropriate. There are currently no controlled studies of youth with misophonia. The current paper describes the approach to a pilot randomized, blinded family-based treatment study for youth ages 8-16 years. Preliminary results from a pilot open trial also are described.

METHODS: A 2-phase dual site telehealth treatment study using a transdiagnostic CBT approach, the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders in Children and Adolescents (UP-C/A; Ehrenreich-May et al., 2018), is proposed. Phase 1 consisted of a 4-case pilot of UP-C/A. Phase 2 includes a randomized trial comparing the UP-C/A to a standard relaxation and education protocol.

RESULTS: Preliminary results from the pilot show modest improvements in evaluator-rated misophonia symptoms on the Clinical Global Impression Severity and Improvement scales.

LIMITATIONS: There is little research to inform evidence-based practice for youth with misophonia. Study limitations include lack of standardized misophonia assessment instruments and an absence of formal diagnostic criteria.

CONCLUSIONS: The current paper describes proposed methods for the first randomized controlled trial for youth with misophonia and their families along with results from a 4-case pilot.

The Role of Community Health Workers in HIV Care Engagement: A Qualitative Study of Stakeholder Perspectives in Tanzania.

The Journal of the Association of Nurses in AIDS Care : JANAC pii:00001782-900000000-99795 [Epub ahead of print].

ABSTRACT: Suboptimal retention in HIV care is a major driver of the global epidemic, including in sub-Saharan Africa. In Tanzania, the national Community-Based HIV Services program integrates volunteer community health workers (CHWs) to support patient care engagement and reduce the burden placed on HIV clinic nurses; however, few studies have assessed the value of CHWs supporting HIV care. Qualitative interviews were conducted with 48 administrators, nurses, CHWs, and patients to explore strengths and limitations of the Community-Based HIV Services program. Stakeholders believed CHWs are uniquely positioned to establish trust and provide patient support. Patients who had frequent contact with CHWs described them as valued sources of education and encouragement, but fewer than half of the patients interviewed had ever met with a CHW. Clinic nurses described feeling disconnected from CHWs, and stakeholders highlighted the need for financial, logistical, and educational support to rejuvenate the program and effectively address care engagement challenges.

Decreased Sound Tolerance in Tinnitus Patients.

Life (Basel, Switzerland), 11(2):.

(1) Background: Decreased sound tolerance is a significant problem in tinnitus sufferers. The aim of the study was to evaluate the relationship between tinnitus and decreased sound tolerance (hyperacusis and misophonia). (2) Methods: The study sample consisted of 74 patients with tinnitus and decreased sound tolerance. The procedure comprised patient interviews, pure tone audiometry, impedance audiometry, measurement of uncomfortable loudness levels, and administration of the Hyperacusis Questionnaire, Tinnitus Handicap Inventory, and Visual Analogue Scales. (3) Results: The majority (69%) of the patients reported that noise aggravated their tinnitus. The correlation between tinnitus and hyperacusis was found to be statistically significant and positive: r = 0.44; p < 0.01. The higher the tinnitus severity, the greater the hyperacusis. There was no correlation between misophonia and hyperacusis (r = 0.18; p > 0.05), or between misophonia and tinnitus (r = 0.06; p > 0.05). (4) Conclusions: For tinnitus patients the more significant problem was hyperacusis rather than misophonia. The diagnosis and treatment of decreased sound tolerance should take into account not only audiological, but also psychological problems of the patients.

A Preliminary Investigation of the Association Between Misophonia and Symptoms of Psychopathology and Personality Disorders.

Frontiers in psychology, 11:519681.

Misophonia is a condition characterized by defensive motivational system emotional responding to repetitive and personally relevant sounds (e.g., eating, sniffing). Preliminary research suggests misophonia may be associated with a range of psychiatric disorders, including personality disorders. However, very little research has used clinician-rated psychometrically validated diagnostic interviews when assessing the relationship between misophonia and psychopathology. The purpose of this study was to extend the early research in this area by examining the relationship between symptoms of misophonia and psychiatric diagnoses in a sample of community adults, using semi-structured diagnostic interviews. Results indicated higher misophonia symptoms were associated with more clinician-rated symptoms of personality disorders, but not other disorders. Anxiety partially mediated the relationship between personality disorder symptoms and misophonia. These results suggest misophonia may be associated with a range of psychiatric symptoms and highlight the role of anxiety in this poorly understood condition.

The Effectiveness of Cognitive-behavioral Therapy on Anger in Female Students with Misophonia: A Single-Case Study.

Iranian journal of medical sciences, 46(1):61-67.

Background: Misophonia is an unpleasant condition, in which the feeling of excessive anger is triggered by specific sounds. The main objective of the present study was to investigate the effectiveness of cognitive-behavioral therapy (CBT) on anger in female students with misophonia.

Methods: A study based on a non-concurrent multiple baseline design was conducted in 2018 at the School of Education and Psychology, Shahid Chamran University of Ahvaz, Ahvaz, Iran. Three female students aged 20-22 years were recruited using the multi-stage random sampling method. The study was conducted in three stages, namely baseline, intervention, and follow-up sessions. The Novaco anger questionnaire was used during the baseline sessions, intervention sessions (sessions three, six, and eight), and six weeks follow-up (two, four, and six weeks after the last intervention session). Data were analyzed using visual analysis, reliability change index (RCI), and recovery percentage formula.

Results: CBT reduced the feeling of anger after the intervention and follow-up sessions. The recovery percentage at the end of the intervention sessions were 43.82, 42.28, and 9.09 for the first, second, and third participants, respectively.

Conclusion: The findings of the present study confirm the effectiveness of CBT in reducing the feeling of anger in female students with misophonia.

Simultaneous auditory agnosia: Systematic description of a new type of auditory segregation deficit following a right hemisphere lesion.

Cortex; a journal devoted to the study of the nervous system and behavior, 135:92-107.

We investigated auditory processing in a young patient who experienced a single embolus causing an infarct in the right middle cerebral artery territory. This led to damage to auditory cortex including planum temporale that spared medial Heschl's gyrus, and included damage to the posterior insula and inferior parietal lobule. She reported chronic difficulties with segregating speech from noise and segregating elements of music. Clinical tests showed no evidence for abnormal cochlear function. Follow-up tests confirmed difficulties with auditory segregation in her left ear that spanned multiple domains, including words-in-noise and music streaming. Testing with a stochastic figure-ground task-a way of estimating generic acoustic foreground and background segregation-demonstrated that this was also abnormal. This is the first demonstration of an acquired deficit in the segregation of complex acoustic patterns due to cortical damage, which we argue is a causal explanation for the symptomatic deficits in the segregation of speech and music. These symptoms are analogous to the visual symptom of simultaneous agnosia. Consistent with functional imaging studies on normal listeners, the work implicates non-primary auditory cortex. Further, the work demonstrates a (partial) lateralisation of the necessary anatomical substrate for segregation that has not been previously highlighted.

Cognitive behavioral therapy for misophonia: A randomized clinical trial.

Depression and anxiety [Epub ahead of print].

BACKGROUND: Patients with misophonia suffer from anger or disgust confronted with specific sounds such as smacking or breathing. Avoidance of cue-related situations results in social isolation and significant functional impairment. This is the first randomized, controlled cognitive behavioral therapy (CBT) trial for misophonia, evaluating the short- and long-term efficacy.

METHODS: The evaluator-blinded, randomized clinical trial was conducted from May 2017 until December 2018 at an academic outpatient clinic. Misophonia patients were randomly assigned to 3 months of weekly group-CBT or a waiting list and tested at baseline, 3 months (following CBT or waiting list), 6 months (after cross-over), and 15/18 months (1-year follow-up). CBT consisted of task concentration and arousal reduction, positive affect labeling, and stimulus manipulation. Co-primary outcomes were symptom severity assessed by the Amsterdam Misophonia Scale-Revised (AMISOS-R) and improvement on the Clinical Global Impression-Improvement (CGI-I). Secondary outcomes were self-assessed ratings of general psychopathology (Symptom Checklist-90-Revised [SCL-90-R]) and quality of life (five-dimensional EuroQol [EQ5-D], Sheehan Disability Scale [SDS], WHO Quality of Life-BREF [WHOQoL-BREF]).

RESULTS: In all, 54 out of 71 patients were included (mean age, 33.06 [SD, 14.13] years; 38 women [70.4%]) and 46 (85%) completed the study. In the randomized phase, CBT resulted in statistically significant less misophonia symptoms in the short-term (-9.7 AMISOS-R; 95% CI, -12.0 to -7.4; p < .001, d = 1.97). The CBT group had an observed clinical improvement (CGI-I < 3) in 37% compared to 0% in the waiting list group (p < .001). The effect of CBT was maintained at 1-year follow-up on primary and secondary outcomes.

CONCLUSIONS: This first randomized control trial shows both short-term and long-term efficacy of CBT for misophonia.

A review of decreased sound tolerance in autism: Definitions, phenomenology, and potential mechanisms.

Neuroscience and biobehavioral reviews, 121:1-17.

Atypical behavioral responses to environmental sounds are common in autistic children and adults, with 50-70 % of this population exhibiting decreased sound tolerance (DST) at some point in their lives. This symptom is a source of significant distress and impairment across the lifespan, contributing to anxiety, challenging behaviors, reduced community participation, and school/workplace difficulties. However, relatively little is known about its phenomenology or neurocognitive underpinnings. The present article synthesizes a large body of literature on the phenomenology and pathophysiology of DST-related conditions to generate a comprehensive theoretical account of DST in autism. Notably, we argue against conceptualizing DST as a unified construct, suggesting that it be separated into three phenomenologically distinct conditions: hyperacusis (the perception of everyday sounds as excessively loud or painful), misophonia (an acquired aversive reaction to specific sounds), and phonophobia (a specific phobia of sound), each responsible for a portion of observed DST behaviors. We further elaborate our framework by proposing preliminary neurocognitive models of hyperacusis, misophonia, and phonophobia that incorporate neurophysiologic findings from studies of autism.

How everyday sounds can trigger strong emotions: ASMR, misophonia and the feeling of wellbeing.

BioEssays : news and reviews in molecular, cellular and developmental biology, 42(12):e2000099.

We propose that synesthetic cross-activation between the primary auditory cortex and the anatomically adjacent insula may help explain two puzzling conditions-autonomous sensory meridian response (ASMR) and misophonia-in which quotidian sounds involuntarily trigger strong emotional responses. In ASMR the sounds engender relaxation, while in misophonia they trigger an aversive response. The insula both plays an important role in autonomic nervous system control and integrates multiple interoceptive maps representing the physiological state of the body to substantiate a dynamic representation of emotional wellbeing. We propose that in ASMR cross-activation of the map for affective (sensual) touch leads to an increase in subjective wellbeing and parasympathetic activity. Conversely, in misophonia the effect of the cross-activation is to decrease emotional wellbeing and increase sympathetic activity. Our hypothesis also illuminates the connection between hearing and wellbeing more broadly and helps explain why so many people experience decreased wellbeing from modern urban soundscapes.

The Mediating Role of Emotion Regulation Within the Relationship Between Neuroticism and Misophonia: A Preliminary Investigation.

Frontiers in psychiatry, 11:847.

Misophonia is a newly described condition characterized by heightened emotional reactivity (e.g., anger, anxiety, and disgust) to common repetitive sounds (e.g., oral or nasal sounds made by others), accompanied by difficulties responding to these sounds (e.g., intolerance, avoidance, and escape) and associated impairment in functioning. Although research indicates that problematic emotional responses are a key characteristic of misophonia, it is unknown whether individual differences in experiencing and regulating emotional responses influence severity of misophonia symptoms. Examination of individual differences in emotional functioning will help to guide treatment development for misophonia. Accordingly, the present study examined the associations among trait neuroticism, difficulties with emotion regulation, and symptoms of misophonia. For this study, a sample of 49 adults completed the Difficulties with Emotion Regulation Scale, the Misophonia Questionnaire, and the neuroticism subscale of the NEO-Personality inventory. Findings indicated that difficulties with emotion regulation and neuroticism were significantly positively correlated with symptoms of misophonia. Bootstrapped mediation analyses suggested that difficulties controlling impulsive behavior while experiencing intense negative emotions fully mediated the relationship between neuroticism and symptoms of misophonia. Results from this study suggest that neuroticism and difficulties with emotion regulation may be important risk factors and treatment targets for adults with misophonia, and difficulties controlling impulsive behavior when distressed may be an important individual difference accounting for the relationship between neuroticism and misophonia.

Misophonia: An Evidence-Based Case Report.

American journal of audiology, 29(4):685-690.

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.

Intraperitoneal injection of lipopolysaccharide prevents seizure-induced respiratory arrest in a DBA/1 mouse model of SUDEP.

Epilepsia open, 5(3):386-396.

Objective: Sudden unexpected death in epilepsy (SUDEP) is the cause of premature death of 50% patients with chronic refractory epilepsy. Respiratory failure during seizures is regarded as an important mechanism of SUDEP. Previous studies have shown that abnormal serotonergic neurotransmission is involved in the pathogenesis of seizure-induced respiratory failure, while enhancing serotonergic neurotransmission in the brainstem suppresses it. Because peripheral inflammation is known to enhance serotonergic neuron activation and 5-HT synthesis and release, we investigated the effect of intraperitoneal lipopolysaccharide (LPS)-induced inflammation on the S-IRA susceptibility during audiogenic seizures in DBA/1 mice.

Methods: After DBA/1 mice were primed by exposing to sound stimulation for three consecutive days, they were tested for seizure severity and seizure-induced respiratory arrest (S-IRA) induced by sound stimulation under different conditions. We determined the dose and time course of the effects of intraperitoneal administration of LPS on audiogenic seizures and S-IRA. The effects of blocking TLR4 or RAGE receptors and blocking 5-HT receptors on the LPS-induced effect on S-IRA were investigated. Statistical significance was evaluated using the Kruskal-Wallis test.

Results: Intraperitoneal injection of LPS significantly had dose-dependent effects in reducing the incidence of S-IRA as well as seizure severity in DBA/1 mice. The protective effect of LPS on S-IRA peaked at 8-12 hours after LPS injection and was related to both reducing seizure severity and enhancing autoresuscitation. Blocking TLR4 or RAGE receptor with TAK-242 or FPS-ZM1, respectively, prior to LPS injection attenuated its effects on S-IRA and seizure severity. Injection of a nonselective 5-HT receptor antagonist, cyproheptadine, or a 5-HT3 receptor antagonist, ondansetron, was effective in blocking LPS-induced effect on S-IRA. Immunostaining results showed a significant increase in c-Fos-positive serotonergic neurons in the dorsal raphe.

Significance: This is the first study that demonstrates the effect of intraperitoneal LPS injection-induced inflammation on reducing S-IRA susceptibility and provides additional evidence supporting the serotonin hypothesis on SUDEP. Our study suggests that inflammation may enhance brainstem 5-HT neurotransmission to promote autoresuscitation during seizure and prevent SUDEP.

The Prevalence and Severity of Misophonia in a UK Undergraduate Medical Student Population and Validation of the Amsterdam Misophonia Scale.

The Psychiatric quarterly, 92(2):609-619.

Misophonia is a condition of abnormal emotional responses to specific auditory stimuli. There is limited information available on the prevalence of this condition. This study aimed to estimate the prevalence of misophonia in an undergraduate medical student population at the University of Nottingham. A secondary aim of this study was to assess the psychometric validity of the Amsterdam Misophonia Scale (A-Miso-S) questionnaire tool in this population. The A-Miso-S was administered online to medical students at the University of Nottingham. To assess the validity of the A-Miso-S, a factor analysis was conducted. To determine prevalence and severity the results of the questionnaire were quantitatively analysed using SPSS. Actor analysis was conducted. Free text responses to one questionnaire item were analysed using a thematic approach. Responses were obtained from 336 individuals. Clinically significant misophonic symptoms appear to be common, effecting 49.1% of the sample population. This is statistically significantly higher prevalence than previous studies have found (p < 0.00001). Using the classification of the A-Miso-S, mild symptoms were seen in 37%, moderate in 12%, severe in 0.3% of participants. No extreme cases were seen. The A-Miso-S was found to be a uni-factorial tool, with good internal consistency. This study has provided new information on misophonia and validity of the A-Miso-S questionnaire in a sample population of UK undergraduate medical students. The results indicate that misophonia is a phenomenon that a significant proportion of medical students experience though only a small subset experience it severely.

Prevalence of Misophonia and Correlates of Its Symptoms among Inpatients with Depression.

International journal of environmental research and public health, 17(15):.

Misophonia is an underexplored condition that significantly decreases the quality of life of those who suffer from it. It has neurological and physiological correlates and is associated with a variety of psychiatric symptoms; however, a growing body of data suggests that it is a discrete disorder. While comorbid diagnoses among people with misophonia have been a matter of research interest for many years there is no data on the frequency of misophonia among people with psychiatric disorders. This could be the next step to reveal additional mechanisms underlying misophonia. Until recently, the use of a variety of non-validated questionnaires and the dominance of internet-based studies have been also a major obstacles to a proper definition of misophonia. A total of 94 inpatients diagnosed with depression were assessed for misophonia with face-to-face interviews as well as with MisoQuest-a validated misophonia questionnaire. The prevalence of misophonia among these patients and the congruence of MisoQuest with face-to-face interviews were evaluated. Additionally, the patients filled in a series of questionnaires that measured a variety of psychiatric symptoms and psychological traits. Anxiety, depression, impulsivity, somatic pain, vegetative symptoms, post-traumatic stress disorder (PTSD) symptoms, gender, and age were analyzed in relation to the severity of symptoms of misophonia. Between 8.5 to 12.76% of inpatients with depression were diagnosed with misophonia (depending on measurement and inclusion criteria). MisoQuest accuracy was equal to 92.55%, sensitivity-66.67% and specificity-96.34%. Severity of misophonia symptoms was positively correlated to the greatest extent with anxiety. Moderate positive correlation was also found between severity of misophonia symptoms and depressive symptoms, intrusions, and somatic pain; a weak positive correlation was found between severity of misophonia and non-planning impulsivity, motor impulsivity, avoidance, and vegetative symptoms. There was no relationship between the severity of misophonia symptoms and attentional impulsivity or the age of participants.

Misophonia: Phenomenology, comorbidity and demographics in a large sample.

PloS one, 15(4):e0231390.

OBJECTIVE: Analyze a large sample with detailed clinical data of misophonia subjects in order to determine the psychiatric, somatic and psychological nature of the condition.

METHODS: This observational study of 779 subjects with suspected misophonia was conducted from January 2013 to May 2017 at the outpatient-clinic of the Amsterdam University Medical Centers, location AMC, the Netherlands. We examined DSM-IV diagnoses, results of somatic examination (general screening and hearing tests), and 17 psychological questionnaires (e.g., SCL-90-R, WHOQoL).

RESULTS: The diagnosis of misophonia was confirmed in 575 of 779 referred subjects (74%). In the sample of misophonia subjects (mean age, 34.17 [SD = 12.22] years; 399 women [69%]), 148 (26%) subjects had comorbid traits of obsessive-compulsive personality disorder, 58 (10%) mood disorders, 31 (5%) attention-deficit (hyperactivity) disorder, and 14 (3%) autism spectrum conditions. Two percent reported tinnitus and 1% hyperacusis. In a random subgroup of 109 subjects we performed audiometry, and found unilateral hearing loss in 3 of them (3%). Clinical neurological examination and additional blood test showed no abnormalities. Psychological tests revealed perfectionism (97% CPQ>25) and neuroticism (stanine 7 NEO-PI-R). Quality of life was heavily impaired and associated with misophonia severity (rs (184) = -.34 p = < .001, p = < .001).

LIMITATIONS: This was a single site study, leading to possible selection-and confirmation bias, since AMC-criteria were used.

CONCLUSIONS: This study with 575 subjects is the largest misophonia sample ever described. Based on these results we propose a set of revised criteria useful to diagnose misophonia as a psychiatric disorder.

Development and Psychometric Properties of MisoQuest-A New Self-Report Questionnaire for Misophonia.

International journal of environmental research and public health, 17(5):.

Background: Misophonia is a condition related to experiencing psychophysiological sensations when exposed to specific sound triggers. In spite of progress in research on the subject, a fully validated questionnaire assessing misophonia has not been published yet. The goal of this study was to create and validate a new questionnaire to measure misophonia. Methods: MisoQuest is based on the diagnostic criteria proposed by Schröder et al. in 2013, with minor changes implemented by the authors of MisoQuest. A total of 705 participants took part in the study, completing the online questionnaires. Exploratory Factor Analysis (EFA) and analyses using the Item Response Theory (IRT) were performed. Internal consistency was evaluated with Cronbach's alpha. Results: The reliability of the MisoQuest was excellent (α = 0.955). The stability at five weeks was strong. There was a significant difference in results between people classified as those with misophonia and those without misophonia. Conclusions: MisoQuest has good psychometric values and can be helpful in the identification of misophonia. A deeper analysis showed that certain triggers might be more specific for people with misophonia. Consideration of violent behavior in response to misophonic triggers as a symptom of misophonia was undermined.

Severity of misophonia symptoms is associated with worse cognitive control when exposed to misophonia trigger sounds.

PloS one, 15(1):e0227118.

The present study aimed to investigate the extent to which the severity of misophonia symptoms is linked with cognitive control under misophonia symptom-provocation circumstances in the general population sample. Participants (N = 79) completed a measure of cognitive control-a Stroop color naming task, which consists of congruent and incongruent stimuli, and requires inhibition of a prepotent response (reading a word) in the service of a less predominant response (naming a color), while listening to misophonia symptom-provocation or universally unpleasant sounds. Participants' misophonia sound sensitivity, and emotional behaviors towards trigger sounds were assessed using the Misophonia Questionnaire. Stronger emotional behavioral reactions to misophonia trigger sounds were significantly associated with the larger Stroop effect when participants were exposed to the misophonia trigger sounds, but not when they were exposed to the universally unpleasant sounds. This effect held when controlling for the personality trait of Neuroticism and for baseline levels of anxiety. Both elevated misophonia sound sensitivity and emotional behaviors towards trigger sounds significantly correlated with higher self-reported anxiety when performing the Stroop task. However, only elevated emotional behaviors towards trigger sounds were linked with higher anxiety levels at baseline, suggesting that people who experience stronger emotions and behavioral reactions to misophonia trigger sounds may have higher anxiety at a trait level. Limitations and future directions are discussed.

Cognitive Behavioral Therapy For Alleviating The Distress Caused By Tinnitus, Hyperacusis And Misophonia: Current Perspectives.

Psychology research and behavior management, 12:991-1002.

This article reviews the evidence related to the efficacy of Cognitive Behavioral Therapy (CBT) for alleviating the distress caused by tinnitus, hyperacusis and misophonia. Where available, the review was focused on meta-analyses of randomized controlled trials (RCTs) using either passive control groups (typically waiting list or education only) or active control groups (receiving some other form of treatment). Where data from RCTs were not available, case studies and retrospective studies were reviewed. Analyses were conducted separately for studies of patients with tinnitus, hyperacusis and misophonia. RCTs show that CBT is effective in alleviating the distress caused by tinnitus in comparison to passive control groups and sometimes active control groups. CBT for tinnitus can be effective both in individual and in group settings, whether delivered by psychiatrists, clinical psychologists, or specially trained audiologists. CBT for tinnitus can also be effective when delivered via the internet, when combined with help from audiologists. Usually, CBT does not reduce the loudness of tinnitus but it can improve quality of life. Case studies and some limited RCTs suggest that CBT can also be effective in alleviating the distress caused by hyperacusis and misophonia. However, RCTs with active control groups are currently lacking. There is strong evidence supporting the effectiveness of CBT in alleviating the distress caused by tinnitus. However, it is not yet clear whether CBT is more effective than some other forms of treatment. RCTs with active control groups are needed to establish more clearly the extent to which CBT is effective in alleviating the distress caused by hyperacusis and misophonia.

Neural Basis of Response Bias on the Stop Signal Task in Misophonia.

Frontiers in psychiatry, 10:765.

Objective: Misophonia is a newly described condition in which specific ordinary sounds provoke disproportionately strong negative affect. Since evidence for psychobiological dysfunction underlying misophonia is scarce, we tested whether misophonia patients, like many patients with impulse control or obsessive-compulsive spectrum disorders, show impaired ability to inhibit an ongoing motor response. Methods: We collected functional magnetic resonance imaging data during a stop signal task in 22 misophonia patients and 21 matched healthy controls. Results: Compared to controls, patients tended to show longer stop signal delays, which is the time between stimuli signaling response initiation and inhibition. Additionally, patients tended to activate left dorsolateral prefrontal cortex more during responding rather than successful inhibition, as was seen in controls. Furthermore, patients lacked inhibition success-related activity in posterior cingulate cortices and activated the superior medial frontal gyri less during inhibition success compared to failure, a feature correlated with stop signal delays over the sample. Conclusions: Misophonia patients did not show impaired response inhibition. However, they tended to show a response bias on the stop signal task, favoring accuracy over speed. This implies perfectionism and compulsive, rather than impulsive, behavior. Moreover, brain activations were in line with patients, compared to controls, engaging more cognitive control for slowing responses, while employing more attentional resources for successful inhibition.

Inattention in misophonia: Difficulties achieving and maintaining alertness.

Journal of clinical and experimental neuropsychology, 42(1):66-75.

Introduction: Misophonia is marked by abnormal negative reactions to specific and idiosyncratic sounds. Despite unclear etiology and diagnostic conceptualization, neuropsychology may be able to help characterize the syndrome. In the current study, we administered the Attention Network Test (ANT) under symptom provocation conditions, as well as secondary measures of concept formation, perseveration, processing speed, and frustration tolerance. We assessed treatment seeking individuals with misophonia and non-clinical controls. We hypothesized higher alerting, orienting, and conflict effects on the ANT suggesting overall poorer performance for the misophonia group.Methods: The sample consisted of symptomatic individuals recruited from a randomized treatment trial prior to the mandatory waitlist (n = 11) and age, gender matched controls (n = 11). Symptomatic individuals were screened with the Misophonia Questionnaire, as well as a number of additional self-report and diagnostic measures.Results: Robust Bayesian estimation in multi-level models suggested worse alerting attention for symptomatic individuals, βMedian = 2.766, βSD = 1.253, 95% CI [0.322, 5.2876], Bayes factor = 31.41. There were no effects respective to block (i.e., blocks before versus during and after symptom provocation) or interaction effects. There were also no effects particular to executive functioning measures but some evidence this domain should be further explored (e.g., ANT conflict effects, perseveration, and serial math accuracy).Conclusions: We propose that symptom provocation alone does not explain the observed group difference in alerting attention, which could reflect a long-standing neuropsychological weakness. Future studies should attempt to characterize misophonia with more comprehensive neuropsychological batteries and larger samples.

Misophonia - a review of research results and theoretical concepts.

Psychiatria polska, 53(2):447-458.

Misophonia is a new and relatively under-explored condition characterized by experiencing strong emotions (mainly anger and disgust) and a physical response (such as muscle constriction, increased heart rate) when exposed to specific sounds. Among the most frequent aversive triggers are the sounds of eating, breathing, or typing. The experience of misophonia is associated with suffering and a significant decrease in quality of life. The phenomenon was first described in 2002. Since then, numerous case studies and data from psychophysiological and neurological and survey research on this phenomenon have been published. These data indicate that misophonia is a consistent phenomenon and preliminary identification is possible. The most recent results show that misophonia occurs independent of other disorders. There are still, however, many questions regarding the definition and diagnostic criteria to be answered. The most important diagnostic issues that are faced during clinical work with people with misophonia are described in this article. Furthermore, the main theoretical concepts and research on misophonia are reviewed and analyzed.

Misophonia is associated with altered brain activity in the auditory cortex and salience network.

Scientific reports, 9(1):7542.

Misophonia is characterized by intense rage and disgust provoked by hearing specific human sounds resulting in social isolation due to avoidance. We exposed patients with symptom provoking audiovisual stimuli to investigate brain activity of emotional responses. 21 patients with misophonia and 23 matched healthy controls were recruited at the psychiatry department of the Amsterdam UMC. Participants were presented with three different conditions, misophonia related cues (video clips with e.g. lip smacking and loud breathing), aversive cues (violent or disgusting clips from movies), and neutral cues (video clips of e.g. someone meditating) during fMRI. Electrocardiography was recorded to determine physiological changes and self-report measures were used to assess emotional changes. Misophonic cues elicited anger, disgust and sadness in patients compared to controls. Emotional changes were associated with increases in heart rate. The neuroimaging data revealed increased activation of the right insula, right anterior cingulate cortex and right superior temporal cortex during viewing of the misophonic video clips compared to neutral clips. Our results demonstrate that audiovisual stimuli trigger anger and physiological arousal in patients with misophonia, associated with activation of the auditory cortex and salience network.

Misophonia and comorbid psychiatric symptoms: a preliminary study of clinical findings.

Nordic journal of psychiatry, 73(4-5):219-228.

Objective: Misophonia is a neurophysiological disorder, phenotypically characterized by heightened autonomic nervous system arousal which is accompanied by a high magnitude of emotional reactivity to repetitive and pattern-based auditory stimuli. This study identifies the prevalence of psychiatric symptoms in misophonia sufferers, the association between severity of misophonia and psychiatric symptoms, and the association between misophonia severity and gender. Methods: Fifty-two misophonia sufferers, 30 females (mean age = 40.93 ± 15.29) and 22 males (mean age = 51.18 ± 15.91) were recruited in our study and they were diagnosed according the criteria proposed by Schröder et al. The participants were evaluated by the A-MISO-S for the severity of misophonia and the MINI to assess the presence of psychiatric symptoms. Results: The most common comorbid symptoms reported by the misophonia patients were respectively PTSD (N = 8, 15.38%), OCD (N = 6, 11.53%), MDD (N = 5, 9.61%), and anorexia (N = 5, 9.61%). Misophonia severity was associated with the symptoms of MDD, OCD, and PTSD as well as anorexia. There was an indication of a significant difference between men and women in the severity of misophonic symptoms. Conclusion: Our findings highlight the importance of recognizing psychiatric comorbidity among misophonia sufferers. The presence of these varying psychiatric disorders' features in individuals with misophonia suggests that while misophonia has unique clinical characteristics with an underlying neurophysiological mechanism, may be associated with psychiatric symptoms. Therefore, when assessing individuals with misophonia symptoms, it is important to screen for psychiatric symptoms. This will assist researchers and clinicians to better understand the nature of the symptoms and how they may be interacting and ultimately allocating the most effective therapeutic strategies.

Cross-Sensory Stimuli Modulate Reactions to Aversive Sounds.

Multisensory research, 32(3):197-213.

We propose that cross-sensory stimuli presenting a positive attributable source of an aversive sound can modulate negative reactions to the sound. In Experiment 1, participants rated original video sources (OVS) of eight aversive sounds (e.g., nails scratching a chalkboard) as more aversive than eight positive attributable video sources (PAVS) of those same sounds (e.g., someone playing a flute) when these videos were presented silently. In Experiment 2, new participants were presented with those eight aversive sounds in three blocks. In Blocks 1 and 3, the sounds were presented alone; in Block 2, four of the sounds were randomly presented concurrently with their corresponding OVS videos, and the other four with their corresponding PAVS videos. Participants rated each sound, presented with or without video, on three scales: discomfort, unpleasantness, and bodily sensations. We found the concurrent presentation of videos robustly modulates participants' reactions to the sounds: compared to the sounds alone (Block 1), concurrent presentation of PAVS videos significantly reduced negative reactions to the sounds, and the concurrent presentation of OVS videos significantly increased negative reactions, across all three scales. These effects, however, did not linger into Block 3 when the sounds were presented alone again. Our results provide novel evidence that negative reactions to aversive sounds can be modulated through cross-sensory temporal syncing with a positive attributable video source. Although this research was conducted with a neurotypical population, we argue that our findings have implications for the treatment of misophonia.

Misophonia: A scoping review of research.

Journal of clinical psychology, 75(7):1203-1218.

OBJECTIVE: To scope the literature describing misophonia populations, management, and research opportunities.

METHOD: Literature searches for research studies describing patients diagnosed with misophonia, defining a patient profile, or outlining development or testing of an intervention for misophonia. A data extraction form was developed and piloted before data from each article were independently charted by two researchers. Researchers then agreed on a final data set for each article.

RESULTS: Thirty-one records were included. The misophonia population was described in terms of onset age, triggers, reaction, coping strategies, and comorbid conditions. We identified nine outcome measures. Case studies on treatments included cognitive behavioral therapy, counterconditioning, mindfulness and acceptance, dialectical behavioral therapy, and pharmaceuticals. Future research priorities identified included clarifying the phenomenology and prevalence of misophonia, and randomized controlled trials of treatments.

CONCLUSION: Misophonia is under-researched but there are strong foundations for future research to finalize diagnostic criteria, validate outcome measures, and trial treatments.

Tics and stereotypies: A comparative clinical review.

Parkinsonism & related disorders, 59:117-124.

Tics and stereotypies are the most common pathological repetitive complex motor behaviors occurring during the neurodevelopmental period. Although they may appear transiently during development without acquiring a pathological status, when they become chronic they may be distressing, socially impairing, or even, in the case of malignant tics, potentially physically harmful. Despite a certain similarity in their phenomenology, physicians should be able to distinguish them for their different variability over time, topographical distribution, association with sensory manifestations, and relationship with environmental triggers. The complex phenomenology of tics and stereotypies is constantly enriched by the characterization of novel variants, e.g. tics triggered by auditory stimuli in association with misophonia and stereotypies associated with intense imagery activity. Their pathophysiology remains partially elusive, but both animal model and brain imaging studies confirm the involvement of all the three major loops (sensorimotor, associative and limbic) within the cortico-basal ganglia circuitry. From a management perspective, the greatest advances witnessed in the last decade involve the diffusion of behavioral strategies (e.g. habit reversal training or response interruption and redirection), including the development of protocols for telehealth on online training in order to optimise access. In the context of severe tics, e.g. in refractory Tourette syndrome, there is increasing experience with deep brain stimulation of the intralaminar thalamic nuclei or the globus pallidus internus, although more research is needed to fine tune target choice and stimulation setting definition.

Increased misophonia in self-reported Autonomous Sensory Meridian Response.

PeerJ, 6:e5351.

Background: Autonomous Sensory Meridian Response (ASMR) is a sensory experience elicited by auditory and visual triggers, which so far received little attention from the scientific community. This self-reported phenomenon is described as a relaxing tingling sensation, which typically originates on scalp and spreads through a person's body. Recently it has been suggested that ASMR shares common characteristics with another underreported condition known as misophonia, where sounds trigger negative physiological, emotional and behavioural responses. The purpose of this study was to elucidate whether ASMR is associated with heightened levels of misophonia.

Methods: The Misophonia Questionnaire (MQ) was administered to individuals reporting to experience ASMR and to age and gender matched controls.

Results: Compared to controls ASMR group scored higher on all subscales of MQ including the Misophonia Symptom Scale, the Misophonia Emotions and Behaviors Scale and the Misophonia Severity Scale.

Discussion: Individuals reporting ASMR experience have elevated levels of misophonia.

Misophonia and Potential Underlying Mechanisms: A Perspective.

Frontiers in psychology, 9:953.

There is a growing research interest in the diagnosis rate of misophonia, a condition characterized by a negative emotional/autonomic reaction to specific everyday sounds. Diagnosis of misophonia requires a thorough case history and audiological test procedures. Associative and non-associative learning models for understanding the underlying mechanisms of misophonia have been presented. Currently, there is no cure or pharmaceutical agent for misophonia; however, therapy programs addressing misophonia and its characteristics do exist. Investigation of comorbid conditions and other psychological therapy strategies might help to reveal more about the underlying mechanisms and potentially lead to a successful treatment method.

Misophonia in Singaporean Psychiatric Patients: A Cross-Sectional Study.

International journal of environmental research and public health, 15(7):.

Misophonia, also known as selective sound sensitivity syndrome, is a condition characterized by strong dislike of specific sounds with accompanying distressing reactions. To date, misophonia is still poorly understood. This study aimed to identify factors associated with severity of misophonic symptoms in Singaporean psychiatric patients. Ninety-two psychiatric patients were recruited from a large teaching hospital in Singapore in a cross-sectional study. Socio-demographics, severity of depression, anxiety and stress, and severity of misophonic symptoms were analyzed. Correlation analysis showed that anxiety, depression, and stress scores&mdash;as measured by the Depression, Anxiety and Stress Scales-21 (DASS-21)&mdash;were significantly positively correlated with the Amsterdam Misophonia Scale (A-MISO-S) scores. After adjustment for confounding factors, multivariate regression analysis showed that anxiety (β = 0.385, p = 0.029) remained significantly associated with A-MISO-S. Age, gender, depression, and stress were not significantly associated with the severity of misophonia. The findings showed that the severity of anxiety was associated with severity of misophonia in Singaporean psychiatric patients. Further research is needed to explore the nature of misophonia and its relationship with other psychiatric disorders.

Uncomfortable loudness levels among children and adolescents seeking help for tinnitus and/or hyperacusis.

International journal of audiology, 57(8):618-623.

OBJECTIVE: To assess the prevalence of hyperacusis and severe hyperacusis among children and adolescents seen at an audiology outpatient tinnitus and hyperacusis service.

DESIGN: This was a retrospective study. Hyperacusis was considered as present if the average uncomfortable loudness level (ULL) at 0.25, 0.5, 1, 2, 4 and 8 kHz for the ear with the lower average ULL, which is denoted as ULLmin, was ≤77 dB HL. Severe hyperacusis was considered as present if the ULL was 30 dB HL or less for at least one of the measured frequencies for at least one ear.

STUDY SAMPLE: There were 62 young patients with an average age of 12 years (SD = 4.1 years, range 4-18 years).

RESULTS: Eighty-five percent of patients had hyperacusis and 17% had severe hyperacusis. On average, ULLs at 8 kHz were 9.3 dB lower than ULLs at 0.25 kHz. For 33% of patients, ULLs were at least 20 dB lower at 8 than at 0.25 kHz.

CONCLUSIONS: Among children and adolescents seen at an audiology outpatient clinic for tinnitus and hyperacusis, hyperacusis diagnosed on the basis of ULLs is very prevalent and it is often characterised by lower ULLs at 8 than at 0.25 kHz.

Evaluation of selective attention in patients with misophonia.

Brazilian journal of otorhinolaryngology, 85(3):303-309.

INTRODUCTION: Misophonia is characterized by the aversion to very selective sounds, which evoke a strong emotional reaction. It has been inferred that misophonia, as well as tinnitus, is associated with hyperconnectivity between auditory and limbic systems. Individuals with bothersome tinnitus may have selective attention impairment, but it has not been demonstrated in case of misophonia yet.

OBJECTIVE: To characterize a sample of misophonic subjects and compare it with two control groups, one with tinnitus individuals (without misophonia) and the other with asymptomatic individuals (without misophonia and without tinnitus), regarding the selective attention.

METHODS: We evaluated 40 normal-hearing participants: 10 with misophonia, 10 with tinnitus (without misophonia) and 20 without tinnitus and without misophonia. In order to evaluate the selective attention, the dichotic sentence identification test was applied in three situations: firstly, the Brazilian Portuguese test was applied. Then, the same test was applied, combined with two competitive sounds: chewing sound (representing a sound that commonly triggers misophonia), and white noise (representing a common type of tinnitus which causes discomfort to patients).

RESULTS: The dichotic sentence identification test with chewing sound, showed that the average of correct responses differed between misophonia and without tinnitus and without misophonia (p=0.027) and between misophonia and tinnitus (without misophonia) (p=0.002), in both cases lower in misophonia. Both, the dichotic sentence identification test alone, and with white noise, failed to show differences in the average of correct responses among the three groups (p≥0.452).

CONCLUSION: The misophonia participants presented a lower percentage of correct responses in the dichotic sentence identification test with chewing sound; suggesting that individuals with misophonia may have selective attention impairment when they are exposed to sounds that trigger this condition.

Misophonia in Children with Tic Disorders: A Case Series.

Journal of developmental and behavioral pediatrics : JDBP, 39(6):516-522.

OBJECTIVE: Misophonia is a condition characterized by the dislike or hatred (miso) of specific sounds (phonia) that results in an extreme emotional response. There has been growing interest in misophonia, with emerging evidence from neurodevelopmental populations and ongoing debate regarding the psychiatric classification and the mechanisms underlying this phenomenon. This is the first article to report on misophonic experiences and associated clinical characteristics in young people with tic disorders.

METHOD: In this article, we present the cases of 12 children and young people with tic disorders who have attended clinics in the United Kingdom and Italy who report misophonia. Misophonia was classified as a selective aversive response in accordance with the criteria proposed by Schröder.

RESULTS: These cases support the view that a range of auditory stimuli may lead to negative/aversive emotional responses of varying degrees, with misophonia seeming to contribute to behavioral reactions. Among these, the most frequent was anger outbursts, followed by an increase in tics, trigger avoidance, repetition of the sound, and self-injurious behavior. No single treatment approach was effective, with some patients responding to cognitive behavioral therapies and others to pharmacological support.

CONCLUSION: We postulate that misophonia could be an underestimated causative phenomenon for abrupt emotional dysregulation in individuals with tic disorders and should be considered as part of a comprehensive clinical assessment. This article presents findings of relevance to general discussions regarding the classification of misophonia, as well as the potential relationship between sensory abnormalities and the broader phenotype of tic disorders during development.

Profile Analysis of Psychological Symptoms Associated With Misophonia: A Community Sample.

Behavior therapy, 49(2):286-294.

Misophonia is characterized by extreme aversive reactions to certain classes of sounds. It has recently been recognized as a condition associated with significant disability. Research has begun to evaluate psychopathological correlates of misophonia. This study sought to identify profiles of psychopathology that characterize misophonia in a large community sample. A total of N = 628 adult participants completed a battery of measures assessing anxiety and anxiety sensitivity, depression, stress responses, anger, dissociative experiences, obsessive-compulsive symptoms and beliefs, distress tolerance, bodily perceptions, as well as misophonia severity. Profile Analysis via Multidimensional Scaling (PAMS) was employed to evaluate profiles associated with elevated misophonia and those without symptoms. Three profiles were extracted. The first two accounted for 70% total variance and did not show distinctions between groups. The third profile accounted for 11% total variance, and showed that misophonia is associated with lower obsessive-compulsive symptoms for neutralizing, obsessions generally, and washing compared to those not endorsing misophonia, and higher levels of obsessive-compulsive symptoms associated with ordering and harm avoidance. This third profile extracted also showed significant differences between those with and without misophonia on the scale assessing physical concerns (that is, sensitivity to interoceptive sensations) as assessed with the ASI-3. Further research is called for involving diagnostic interviewing and experimental methods to clarify these putative mechanisms associated with misophonia.

Investigating Misophonia: A Review of the Empirical Literature, Clinical Implications, and a Research Agenda.

Frontiers in neuroscience, 12:36.

Misophonia is a neurobehavioral syndrome phenotypically characterized by heightened autonomic nervous system arousal and negative emotional reactivity (e. g., irritation, anger, anxiety) in response to a decreased tolerance for specific sounds. The aims of this review are to (a) characterize the current state of the field of research on misophonia, (b) highlight what can be inferred from the small research literature to inform treatment of individuals with misophonia, and (c) outline an agenda for research on this topic. We extend previous reviews on this topic by critically reviewing the research investigating mechanisms of misophonia and differences between misophonia and other conditions. In addition, we integrate this small but growing literature with basic and applied research from other literatures in a cross-disciplinary manner.

Sensory determinants of the autonomous sensory meridian response (ASMR): understanding the triggers.

PeerJ, 5:e3846.

The autonomous sensory meridian response (ASMR) is an atypical sensory phenomenon involving electrostatic-like tingling sensations in response to certain sensory, primarily audio-visual, stimuli. The current study used an online questionnaire, completed by 130 people who self-reported experiencing ASMR. We aimed to extend preliminary investigations into the experience, and establish key multisensory factors contributing to the successful induction of ASMR through online media. Aspects such as timing and trigger load, atmosphere, and characteristics of ASMR content, ideal spatial distance from various types of stimuli, visual characteristics, context and use of ASMR triggers, and audio preferences are explored. Lower-pitched, complex sounds were found to be especially effective triggers, as were slow-paced, detail-focused videos. Conversely, background music inhibited the sensation for many respondents. These results will help in designing media for ASMR induction.

Familial misophonia or selective sound sensitivity syndrome : evidence for autosomal dominant inheritance?.

Brazilian journal of otorhinolaryngology, 84(5):553-559.

INTRODUCTION: Misophonia is a recently described, poorly understood and neglected condition. It is characterized by strong negative reactions of hatred, anger or fear when subjects have to face some selective and low level repetitive sounds. The most common ones that trigger such aversive reactions are those elicited by the mouth (chewing gum or food, popping lips) or the nose (breathing, sniffing, and blowing) or by the fingers (typing, kneading paper, clicking pen, drumming on the table). Previous articles have cited that such individuals usually know at least one close relative with similar symptoms, suggesting a possible hereditary component.

OBJECTIVE: We found and described a family with 15 members having misophonia, detailing their common characteristics and the pattern of sounds that trigger such strong discomfort.

METHODS: All 15 members agreed to give us their epidemiological data, and 12 agreed to answer a specific questionnaire which investigated the symptoms, specific trigger sounds, main feelings evoked and attitudes adopted by each participant.

RESULTS: The 15 members belong to three generations of the family. Their age ranged from 9 to 73 years (mean 38.3 years; median 41 years) and 10 were females. Analysis of the 12 questionnaires showed that 10 subjects (83.3%) developed the first symptoms during childhood or adolescence. The mean annoyance score on the Visual Analog Scale from 0 to 10 was 7.3 (median 7.5). Individuals reported hatred/anger, irritability and anxiety in response to sounds, and faced the situation asking to stop the sound, leaving/avoiding the place and even fighting. The self-reported associated symptoms were anxiety (91.3%), tinnitus (50%), obsessive-compulsive disorder (41.6%), depression (33.3%), and hypersensitivity to sounds (25%).

CONCLUSION: The high incidence of misophonia in this particular familial distribution suggests that it might be more common than expected and raises the possibility of having a hereditary etiology.

ESP Quick Facts

ESP Origins

In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.

ESP Support

In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.

ESP Rationale

Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.

ESP Goal

In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.

ESP Usage

Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.

ESP Content

When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.

ESP Help

Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.

ESP Plans

With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.

Papers in Classical Genetics

The ESP began as an effort to share a handful of key papers from the early days of classical genetics. Now the collection has grown to include hundreds of papers, in full-text format.

Digital Books

Along with papers on classical genetics, ESP offers a collection of full-text digital books, including many works by Darwin (and even a collection of poetry — Chicago Poems by Carl Sandburg).

Timelines

ESP now offers a much improved and expanded collection of timelines, designed to give the user choice over subject matter and dates.

Biographies

Biographical information about many key scientists.

Selected Bibliographies

Bibliographies on several topics of potential interest to the ESP community are now being automatically maintained and generated on the ESP site.
