Misophonia From Wikipedia, the free encyclopedia Misophonia, literally hatred of sound, is a neurological disorder in which negative experiences (anger, flight, hatred, disgust) are triggered by specific sounds.[1] The sounds can be loud or soft.[2] The term was coined by American neuroscientists Pawel Jastreboff and Margaret Jastreboff[3] and is often used interchangeably with the term selective sound sensitivity.[4] Misophonia has not been classified as a discrete disorder in DSM-5 or ICD-10, but in 2013 three psychiatrists at the Academic Medical Center in Amsterdam formulated diagnostic criteria for it based on the largest cohort of misophonia patients so far, and suggested that it be classified as a separate psychiatric disorder.[5] The disorder comprises a unique set of symptoms, most likely attributable to neurological causes unrelated to hearing-system dysfunction. It can be described as an immediate and extremely negative emotional response accompanied by an automatic physiological flight response to identifiable auditory, visual, and olfactory stimuli. The disorder disrupts daily living and can have a significant impact on social interactions. A 2013 review of the most current neurological studies and fMRI studies of the brain as it relates to the disorder[6] postulates that abnormal or dysfunctional assessment of neural signals occurs in the anterior cingulate cortex and insular cortex. These cortices are also implicated in Tourette Syndrome, and are the hub for processing anger, pain, and sensory information. Other researchers concur that the dysfunction is in central nervous system structures.[7] It has been speculated that the anatomical location may be more central than that involved in hyperacusis.
