Why Misophonia Belongs in Diagnostic Manuals
Misophonia is real and it's time that the diagnostic manuals catch up.

Key points
- Misophonia triggers intense emotional and physical reactions, severely disrupting daily life activities.
- Neurobiology links misophonia to the anterior insular cortex and disrupted salience network connectivity.
- Lived experiences reveal misophonia's emotional, social, and financial toll on sufferers and families.
Imagine sitting down for a family meal, only to feel a sudden surge of anger or panic as the sound of chewing fills the room. Or perhaps you're at work, trying to concentrate, but the repetitive tapping of a pen makes it impossible to focus. For individuals with misophonia, these scenarios are daily realities that disrupt their lives in profound and often isolating ways.
Understanding Misophonia
Misophonia, literally meaning “hatred of sound,” is more than just a strong dislike for certain noises. It is a neurological condition where specific auditory or visual stimuli, such as chewing, tapping, or repetitive movements, trigger intense emotional and physiological reactions. These responses can include anger, panic, disgust, and physical symptoms like increased heart rate and sweating.
Research reveals that these reactions are not merely behavioral quirks but are deeply rooted in the brain. Studies have shown hyperactivity in the anterior insular cortex (AIC), a region associated with emotional processing and sensory integration. This heightened activity underscores why these stimuli feel overwhelmingly intrusive to those with misophonia (Kumar et al., 2017).
The condition often begins in childhood or adolescence and can worsen over time, leading to avoidance behaviors that affect daily life. Social events, classrooms, workplaces, and even family gatherings can become minefields of potential triggers, leaving sufferers feeling isolated and misunderstood.
Prevalence and Misunderstanding
Although misophonia is not yet widely recognized in medical diagnostic systems like the ICD-11, it is far from rare. Estimates suggest that between 6% and 20% of the population experiences misophonia to varying degrees (Jakubovski et al., 2022). Despite its prevalence, the condition remains poorly understood by many clinicians, leaving patients without adequate treatment or validation.
This lack of recognition perpetuates a cycle of stigma and neglect. People with misophonia often encounter skepticism about their experiences, with others dismissing their reactions as exaggerated or attention-seeking. This dismissiveness not only deepens their sense of isolation but also hinders their ability to seek help.
The Neurobiology of Misophonia
The neurobiological profile of misophonia distinguishes it from other sensory processing conditions. Research points to a dysregulated salience network in the brain, which governs the integration of sensory and emotional information. This network’s atypical functioning explains why certain sounds or sights are perceived as disproportionately distressing (Eijsker et al., 2019).
Moreover, misophonia has been linked to interoceptive dysregulation—an impaired ability to interpret internal bodily signals. This may amplify the intensity of emotional and physical responses to triggers, further complicating the condition’s management (Schmitt & Schoen, 2022).
The Human Toll
While science provides critical insights into misophonia, the lived experiences of those who endure it offer a deeper understanding of its impact. Testimonies from sufferers paint a vivid picture of the challenges they face.
One individual shared, “Misophonia has taken over my life. I can’t enjoy meals with my family or work in an office environment without feeling overwhelmed.” For many, simple pleasures like dining out or attending a movie become sources of anxiety.
Families, too, are profoundly affected. Parents of children with misophonia describe the difficulty of navigating a world filled with potential triggers. “Our entire life revolves around avoiding my son’s triggers,” one parent explained, illustrating the far-reaching implications of the condition.
Why Diagnostic Recognition Matters
The absence of misophonia from diagnostic manuals like the ICD-11 has tangible consequences. Without formal recognition, patients struggle to access appropriate care, insurance coverage, and accommodations in educational or workplace settings. This lack of support exacerbates the emotional and financial toll on individuals and their families.
Inclusion in diagnostic manuals would mark a significant step forward. It would validate the experiences of those with misophonia, reduce societal stigma, and pave the way for improved research and treatment. Importantly, it would also encourage clinicians to recognize and address the condition, ensuring that sufferers are no longer dismissed or left without options.
A Call for Understanding
Misophonia is a complex and often misunderstood condition that demands greater attention from the medical and psychological communities. By incorporating it into diagnostic frameworks, we can begin to provide the validation, support, and resources that individuals with misophonia so desperately need. The International Misophonia Foundation submitted a proposal to the ICD-11 for consideration of classifying misophonia.
For those affected, recognition would not just be a step forward in treatment—it would be an acknowledgment that their struggles are real, significant, and deserving of compassion. It’s time for misophonia to take its rightful place in the diagnostic landscape.
