If you react with anger or disgust to certain trigger sounds, such as chewing, slurping, heavy breathing, snoring, sniffling, foot tapping, and typing, you might suffer from misophonia. Once coined a condition, new research has misophonia considered an actual disorder.

In February 2017, a team of scientists lead by Newcastle University in the U.K. took brains scans of people with misophonia. When researchers played the trigger sounds, the subjects experienced "hyperactivity" and "abnormal functional connectivity" in the medial frontal, medial, parietal, and temporal regions of their brains. Some subjects also experienced an increased heart rate and sweating. Their study suggests that people with misophonia experience dramatic emotional and physical responses to commonly occurring sounds. The study does note that more research must be done to decide whether misophonia is a cause or consequence of atypical interoception.
