Misophonia - a disease of obsessive sounds: patients can be relieved of it

People often encounter such a phenomenon when certain sounds can cause them not only irritation but also rage. It can be the sounds of swallowing too loudly, tapping on the table, humming out loud, the sound of a whistle and many others that constantly accompany a person. Part of the world's population does not notice them or notices but does not respond. But another part of people is painful to these sounds.

They cause discomfort. Research conducted by scientists suggests that an irritating reaction to sounds is a disease. It is associated with the frontal lobe of the brain. The disease is called misophonia. It manifests itself as a neurological condition. It describes unreasonable emotions that are amplified if a person exposed to misophonia hears sounds unpleasant for him.

Patients can experience irritation and rage from a click of the keyboard, from the rustle of a packet of chips and other minor sounds. A study of the causes of the spread of misophonia was conducted for the first time in 2000 and was immediately limited, as most experts concluded that such a reaction is just a separate sense of hearing.

The Diagnostic and Statistical Manual of Mental Disorders does not contain official criteria by which to determine whether it is a disorder, a disease, or simply a reaction to sound. In 2014, another study in Australia found that misophonia could affect up to 20 per cent of the population.

A year later, scientists found that misophonia is directly related to aggressively-compulsive disorder and anxiety and can potentially be considered as a disorder in itself. In 2017, a team led by researchers from the University of Newcastle in the UK found evidence of new evidence that the reaction to external factors cannot be ignored by doctors.

Misophonia is associated with changes in the frontal lobe of the brain. And these changes can explain the emotional response caused by sounds. A group of 20 volunteers was created. All of them reported that they were experiencing discomfort at certain sounds, they were annoyed by a boiling kettle, crying, breathing, loud chewing.

Their neurological and physiological reactions were compared with another group of volunteers who had no reactions to extraneous sounds. They were offered to listen to annoying sounds and the participants of the first group showed an increase in heart rate, which indicates the manifestation of misophonia.

Brain scans also revealed a marked difference in the neurology of the subjects. In patients with misophonia, triggering noises correlated with increased activity in various areas of the brain, including the frontal lobe. Scientists believe that it is possible to choose options for complex treatment to save people from this disorder.
