Misophonia is most-likely a neurological affliction that causes a fight/flight/freeze response to otherwise normal visual and audial stimuli. As of now, there is no official consensus on what exactly causes the disorder. Though it was coined in 2001 by Jastreboff and Jastreboff there has been little research published under the disorder’s current name.
Researchers such as Joseph E. LeDoux and Stephen Porges have been researching auditory over-responsivity. However, the name of the disorder matters little since researchers are more focused on what’s going on inside the brain and body and not merely perceived notions and sweeping generalizations.
Many that sufferer from misophonia struggle with similar symptoms. Commonly, tapping, whistling, chewing, and other repetitive sounds cause this severe reaction. Though the disorder manifests with aversions to sights and sounds, many are proposing that its cause is physiological and not psychological.
