Many people are annoyed to the point of being unable to stand the sound of chewing food or gum from the person next to them. Or even the sound of a pen being pressed or breathing can be irritating. In fact, the problem may not be with the person doing it, but rather with a brain disorder called misophonia.
Misophonia is a disorder in which people are hypersensitive to sounds that are cause by the actions of others and are usually sounds that people do not normally pay attention to. Such as chewing gum, food, breathing, pens being pressed. Keyboards being pressed, or coins being clanged. These sounds can trigger a response called the fight-or-flight response.
It causes those who experience the sound to feel negative, irritated, and even angry or want to escape from the source of the sound.
A team of researchers from Newcastle University in the UK discovered that people with misophonia have abnormalities in the brain’s frontal lobe and anterior insular cortex (AIC), areas of the brain involved in emotional regulation, which makes patients more sensitive to specific sounds. Known as “trigger sounds.”
The researchers used magnetic resonance imaging (MRI) to measure brain activity in volunteers. With and without misophonia while listening to a variety of sounds. The sounds were divided into neutral sounds, such as rain, boiling water, and a commotion in a cafe ; ทางเข้า https://ufabet999.app and unpleasant sounds. Such as a baby crying or screaming. Trigger sounds were breathing and chewing. The study found that the stimulating sounds caused the brains of people.
With misophonia to function differently than those without the disorder. However, there was no significant difference between the neutral and unpleasant sounds.
The anterior insula plays a key role in processing emotions and regulating responses to external stimuli. The results of the test show. That when the subjects were exposed to sound stimuli. The brain images of those with mesophonia show significantly increased activity in the frontal cortex. And anterior insula, particularly in areas responsible for long-term memory, fear, and emotions. In contrast, those without the disorder had increased activity in the anterior insula but decreased activity in the frontal cortex. The researchers also found that the sound stimuli could evoke physiological responses of increased heart rate and sweating.
The data suggest that the abnormal control mechanisms of the two brain regions and the differences in the patterns of their connections are likely to lead to the clinical diagnosis of misophonia. Although misophonia has no medical diagnosis. The results of the study provide concrete evidence that aversion to sounds, especially those produced by chewing or breathing, is one of the clinical symptoms. The researchers believe that these findings will help to evaluate treatment options.
If anyone thinks they have symptoms of misophonia or is unsure. About their symptoms, it is recommended that they see a doctor to receive proper treatment.
