RESPONSE TO LOUD SOUND AND HYPERSENSITIVE BRAIN CONNECTIONS
To people who respond to sounds such as loud chewing or breathing may have an hypersensitive brain connection. This new finding, scientists have revealed, could help treat people suffering from mizophonia.
People who react to certain sounds, particularly loud chewing and breathing, may have hypersensitive brain connectivity, according to a new study.
Neurology scientists at Newcastle University have discovered a growing link between the auditory cortex and motor control areas associated with the face, mouth and throat in people suffering from mizophony.
Mizophony, which means hatred of sound, is a condition that people experience by giving intense and involuntary reactions to certain sounds made by others and called triggers.

FIRST IDENTIFIED
Research fallowed at the Institute of Biosciences at Newcastle University, of research: “our findings show that there is abnormal communication between auditory and motor brain regions in people with mizophony. You can define this as an over-sensitized connection. This is the first time such a link has been detected in the brain for the condition.” Mizophony is a condition that affects about 15% of adults worldwide and is more common in women than in men. Discomfort has long been considered a sound processing disorder, but findings from Newcastle University suggest it’s much more than that.

WHAT IS A MIRROR SYSTEM?
The scientists performed brain scans on those with and without mizophony and found that in people with mizophony, communication between the auditory cortex and motor control areas related to the face, mouth and throat increased. Dr. “What surprised us was that we found a similar pattern of communication between visual and motor regions, reflecting that mizophony can also occur when triggered by something visual,” was said. These results lead us to believe that movements made by other individuals activate something called the ‘mirror system’, which helps us process our own brain in a similar way – as if we are making these movements ourselves.

NEW TREATMENT METHODS CAN BE DEVELOPED
In patients with mizophony, we believe that excessive activation of the mirror system leads to a perception that sounds made by others are intruding on their bodies outside their control. Interestingly, some people with mizophony can reduce their symptoms by mimicking the action that creates the triggering sound. Using this information could help us develop new treatments for people with mizophonia.”
