Body

A 2017 study by Kumar and colleagues examined structural and functional brain abnormalities in individuals with misophonia by exposing participants to three sound classes (trigger, generally aversive, neutral) while collecting fMRI, heart rate, galvanic skin response, and subjective self-reports. In addition to neural and autonomic differences, analysis of self-report measures indicated that misophonic participants reported altered perception of their own bodily states, consistent with atypical interoception. The authors note that these findings suggest abnormal processing of internal body signals in misophonia, but state that the current data cannot determine whether misophonia is a cause or consequence of atypical interoception.
