Abstract
| Background/Purpose | Background- • Misophonia involves reduced tolerance to certain sounds and is linked to functional impairments and psychiatric comorbidities. • BD patients are known to exhibit sensory processing deficits and impaired auditory filtering, potentially predisposing them to misophonia. • Misophonia shares neurobiological features with autism spectrum disorder (ASD), especially in sensory sensitivity and insular cortex involvement. • Emotion regulation deficits are common in misophonia and BD and are associated with worse outcomes and increased psychopathology. Purpose- • Determine misophonia prevalence in bipolar disorder (BD) patients. • Assess the relationship between misophonia and autistic traits and emotion regulation skills in BD. • Compare results with a demographically matched healthy control group. • Hypotheses: Misophonia would be more prevalent in BD; misophonia severity would correlate with emotion dysregulation and autism traits. |
| Participants/samples | • 105 BD patients (DSM-5 diagnosis; in remission ≥3 months). • 105 matched healthy controls (age, gender, education). • Age range: 18–65 years. • Exclusion: other major psychiatric diagnoses, cognitive impairment, intellectual disability. |
| Measures | • Hamilton Depression Rating Scale (HDRS) – Depression severity. • Young Mania Rating Scale (YMRS) – Mania severity. • AMISOS-R – Misophonia symptoms. • ERSQ – Emotion regulation. • AQ – Autism spectrum traits. |
| Procedures | • Clinical interview for BD diagnosis and remission verification. • Self-report scales administered post-consent. • BD and control groups compared on scale scores and misophonia prevalence. • Regression analysis conducted to identify predictors of misophonia severity. |
| Results | • Prevalence: • Misophonia more common in controls (63.8%) than BD group (48.6%) (p=0.026). • BD patients with misophonia had higher AQ scores (p=0.003) and greater history of suicide attempts (p=0.026). • Severity: • Within BD: 29.4% subthreshold, 45.1% mild, 19.6% moderate, 5.9% severe misophonia. • AMISOS-R severity not significantly correlated with ERSQ or AQ scores in bivariate analysis. • Regression: • Suicide attempt history and AQ score significantly predicted misophonia severity. • Triggers and Reactions: • Chewing and breathing sounds were top triggers. • Discomfort and disgust were more common reactions in controls. • Gender/Hormonal Findings: • 7 of 16 reproductive-aged females reported worsened symptoms during menstruation. • Auditory Processing: • BD patients had more self-reported hearing difficulties than controls (p=0.020). |
| Discussion/Limits | Conclusion- • Contrary to hypotheses, misophonia was more prevalent in the control group. • In BD, misophonia was linked to higher autistic traits and suicide attempt history. • Emotion regulation skills were poorer in BD patients, particularly with high autistic traits. • Misophonia severity predicted by suicide attempt history and autism spectrum traits. • Misophonia may not be fully captured by current nosological frameworks; subtypes may exist. |
| Limitations:: | • Cross-sectional design limits causal inference. • Single-site sample may limit generalizability. • Medication use not analyzed—possible confounder. • Hearing status based on self-report; objective testing recommended. |
| Future Directions:: | • Explore misophonia subtypes (pure vs. comorbid). • Clarify the role of pharmacology in symptom expression. • Use objective sensory testing and broader community sampling. • Further investigate emotion regulation components and hormonal influences (e.g., menstrual cycle). |
| Relevance:: | • study looking at the prevalence of Misophonia → Bipolar disorder (BD) comorbidity , the link between Misophonia and autistic traits and emotional regulation skills in BD. they found Misophonia to be more common in those without BD • they suggest that there may be subtypes of Misophonia that warrant further study (pure vs comorbid ) |
Notes
key terms
-
Misophonia – A condition marked by intense negative emotional reactions (e.g., anger, disgust) to specific auditory stimuli such as chewing or breathing sounds. Not yet formally classified in diagnostic manuals.
-
Autism Spectrum Quotient (AQ) – A self-report scale assessing autistic traits across five domains: social skills, attention switching, attention to detail, communication, and imagination.
-
Emotion Regulation Skills Questionnaire (ERSQ) – A self-report scale measuring individuals' skills in regulating emotions.
-
Amsterdam Misophonia Scale-Revised (AMISOS-R) – A scale used to assess misophonia symptom severity and functional impairment, scored from 0 (none) to 40 (extreme).
-
Salience Network – A brain network (including the insular cortex) implicated in identifying and filtering relevant sensory stimuli; associated with misophonia and autism.
