New research suggests people with misophonia have increased connectivity in the brain between the auditory cortex and the motor control areas related to the face, mouth and throat.

A ‘supersensitised’ brain connection has been identified in people who suffer an extreme reaction to trigger sounds such as chewing or loud breathing.

For many people the sound of someone eating or clicking a pen can be annoying, but sufferers of the condition misophonia feel disgust and even rage when exposed to certain noises.

Now, research led by Newcastle University has discovered increased connectivity in the brain between the auditory cortex and the motor control areas related to the face, mouth and throat.

“Our findings indicate that for people with misophonia there is abnormal communication between the auditory and motor brain regions – you could describe it as a ‘supersensitised connection’,” said lead author of the study, Dr Sukhbinder Kumar.
