Abstract
Misophonia is a complex neurobehavioral syndrome phenotypically characterized by heightened autonomic nervous system arousal and negative emotional reactivity, in response to a decreased tolerance for specific sounds1,2. Some people with Misophonia report aversive responses to certain visual and tactile stimuli. The small body of research on Misophonia suggests that individuals suffering from this condition experience extreme autonomic arousal1 when exposed to ordinary auditory stimuli. Sufferers report physical sensations, and actions such as teeth clenching and muscle tightening. Emotional reactions and feeling-states include extreme annoyance, anger, rage, and anxiety. Misophonia is not classified in DSM-V or ICD-10, and most people are self-diagnosed. Research from basic and applied fields are synthesized with studies explicitly designed to investigate misophonia in an effort to more specifically conceptualize this syndrome. The current study identifies several cognitive and affective aspects of Misophonia in over 300 misophones. Phonophilia, depression, anxiety, ADD, OCD and PTSD have the highest symptom overlap with Misophonia. Despite the suggested potentially clinical resemblance of Misophonia with OCSD, still the condition should be described as a separate condition2,3 in DSM-V, based on severity of the symptoms, and the distinctiveness of the combination of symptoms. Our data reveal co-morbidity with PTSD. Subjects with PTSD also report more severe Misophonic complaints than subjects without PTSD. Furthermore, according to our data, almost half of the Misophonics experience ASMR (Autonomous sensory meridian response) to various degrees. In our sample, 66 subjects report severe distress caused by their Misophonia, experiencing panic/rage reactions as well as reporting actual use of physical violence (often self-harming). Given the impairing nature of this condition, further research is clearly warranted regarding etiology, phenotypes, and cognitive and neurological properties of this condition.
