Understanding misophonia: A growing focus in mental health

Misophonia has moved from an obscure audiological footnote to a recognised focus of neuropsychiatric and mental health research in under two decades. The shift reflects both growing patient advocacy — millions of people recognising their experience in descriptions of the condition — and expanding neuroscience that has begun to explain why certain sounds trigger what feels like an involuntary, overwhelming response. Here is where the science currently stands.

Why Misophonia Is Getting More Attention

Several converging factors have elevated misophonia's clinical profile. First, social media and patient communities enabled people with misophonia to find each other and name their shared experience — creating the kind of patient pressure that historically precedes formal diagnostic recognition (as it did with ADHD, fibromyalgia, and complex PTSD). Second, neuroimaging studies — particularly Kumar et al. (2017) in Current Biology — provided objective evidence of abnormal brain activity patterns distinguishing misophonia from voluntary aversive reaction to sound. Third, the COVID-19 pandemic, which put many people with misophonia into prolonged close contact with household members, dramatically increased the number of people seeking help.

The Connection to ADHD and Other Neurodevelopmental Conditions

Misophonia shows substantial co-occurrence with ADHD, autism spectrum disorder (ASD), and OCD. Among clinical samples of people with misophonia, ADHD is present in approximately 30–50% and ASD features in 20–30%. A 2020 study by Dietz and colleagues found that sensory over-responsivity — a broader trait involving heightened sensitivity across multiple sensory modalities — was elevated in ADHD, ASD, and misophonia and may represent a shared underlying dimension.

In ADHD specifically, the connection may partly relate to difficulties with attentional filtering. The ADHD brain has weaker suppression of irrelevant stimuli, which means repetitive background sounds that neurotypical brains habituate to remain salient. When a sound is simultaneously unfilterable and aversive, the misophonia response — disproportionate anger or disgust — may develop through conditioning: the sound becomes associated with emotional arousal that builds into the near-automatic trigger response characteristic of the condition.

Where Misophonia Sits Diagnostically

Despite increasing research attention, misophonia does not yet appear as a standalone diagnosis in either DSM-5 or ICD-11. Proposals for its inclusion have been submitted and are under active consideration. The absence of an official diagnostic code creates practical difficulties: insurance coverage for misophonia-specific treatment is inconsistent, clinicians vary in their familiarity with the condition, and some patients continue to receive dismissive responses when seeking help.

A 2022 international expert consensus paper (Swedo et al.) proposed a formal definition and diagnostic criteria for misophonia that may inform future classification decisions. The proposed criteria require: a specific trigger sound; a conditioned aversive emotional response (anger, disgust, or panic rather than fear as in phonophobia); functional impairment; and exclusion of better-explained conditions.

Living With Misophonia: What Actually Helps

In the absence of validated medication treatments, people with misophonia typically rely on a combination of cognitive behavioural strategies, environmental modifications, and harm reduction. Wearing ear protection or noise-cancelling headphones in triggering environments can substantially reduce the frequency of trigger exposure. Communicating with family members or colleagues about specific triggers — while difficult — prevents the secondary relationship damage from unexplained angry responses.

Mindfulness-based approaches do not eliminate the trigger response but can reduce the secondary response to the response — the shame, self-criticism, and avoidance behaviour that compounds the primary aversive reaction. Acceptance and Commitment Therapy (ACT) frameworks that work with the distress without requiring it to disappear are increasingly reported as helpful by people with misophonia who have tried multiple approaches.

For people with comorbid ADHD, treating the ADHD effectively may reduce the overall sensory burden — improved attentional filtering can reduce the degree to which sounds are intrusive, even if the conditioned misophonia response to specific triggers persists.
