Please, Stop that Crunching!
If you find yourself beyond irritated by the sound of someone munching popcorn in a movie theater, snapping gum or clicking a pen in the office, or the way your partner noisily sips his coffee or slurps his soup, you may have a condition called misophonia.
This aversion to repetitive sounds was first identified in 2001, but in the years since then, many scientists were unsure about whether the condition actually existed or not. New research now shows that there is an actual difference in the brain's frontal lobe in people with misophonia compared with those who do not have the condition.
For the study, researchers conducted MRI scans of the brains of people with and without misophonia as they listened to a variety of sounds—neutral sounds like rain, unpleasant sounds like a baby crying, and trigger sounds like eating and loud breathing. Trigger sounds produced different brain activity in people with misophonia, proving the condition is an actual disorder.
