# Assessing misophonia as a potential comorbidity in migraine patients compared to controls: a cross-sectional study

## TL;DR

This study found that misophonia, a condition causing strong reactions to everyday sounds, is much more common and severe in people with migraines than in healthy individuals.

## Contribution

The study is the first to show a strong link between misophonia and migraine, highlighting shared sensory and psychological features.

## Key findings

- Migraine patients had a 44.9% prevalence of misophonia compared to 17.6% in controls.
- Misophonia in migraine patients was linked to higher migraine disability and sensory sensitivities.
- Stress, obsessive-compulsive symptoms, and allodynia predicted higher misophonia severity in migraine patients.

## Abstract

This study aimed to investigate the prevalence and symptom severity of misophonia among individuals with migraine, and to explore its clinical and psychological correlates.

Misophonia is a neurobehavioral condition characterized by intense emotional and physiological reactions to specific everyday sounds, such as chewing or tapping. Although misophonia has been associated with increased sensory sensitivity and psychiatric comorbidities, its relationship with other sensory processing disorders-particularly migraine-remains underexplored.

In this cross-sectional study, 205 migraine patients and 205 healthy controls completed validated scales assessing misophonia symptoms, psychiatric comorbidities, and migraine-related disability. Statistical comparisons and univariate linear regression analyses were performed to identify predictors of misophonia.

Our findings revealed a significantly higher prevalence of misophonia among individuals with migraine compared to healthy controls (44.9% vs. 17.6%). Misophonia symptoms were not only more common but also more severe in the migraine group. Migraine patients with comorbid misophonia scored significantly higher on the Headache Impact Test-6 and all components of the Migraine Disability Assessment Scale compared to those without misophonia. Sensory sensitivities such as photophobia, phonophobia, osmophobia, and allodynia were also more frequent and intense among migraine patients with misophonia. Furthermore, these patients exhibited significantly higher levels of anxiety, stress, and obsessive-compulsive symptoms. Regression analyses revealed that stress, obsessive-compulsive symptoms, allodynia, and migraine-related disability were significant predictors of misophonia scores.

Misophonia is a common and clinically significant comorbidity in migraine, associated with heightened sensory sensitivities, increased psychiatric burden, and greater functional impairment. The co-occurrence of these conditions may be underpinned by shared neurobiological mechanisms, particularly networks mediating sensory-emotional integration. Further longitudinal and neurobiological research is warranted to clarify causal relationships and inform targeted interventions.
