However, when the participants had to make mouth sounds, this activity did not show the same connectivity, which led the researchers to think the old research “was not capturing true orofacial cortex.”Īdditionally, the brain imaging captured when the participants were tapping their fingers showed more activity in the insula area of the brain. As was the case with the older study, they saw that the people who scored higher for misophonia had a stronger connection in the auditory cortex and orofacial motor cortex regions of the brain. The researchers scanned the brains of participants who were in a resting state to see if they could replicate the results of a 2021 study. These states allowed the researchers to determine which parts of the participants’ brains were activated at different times. The participants underwent MRI scanning in three states: Some of the participants had no misophonia symptoms while others experienced the condition.
Prior misophonia research has mostly focused on how chewing sounds affect people with the condition.įor the new study, OSU researchers recruited 19 participants. Misophonia: More than just chewing sounds By contrast, another study from 2018 shows that some people with misophonia could find ASMR to be agitating. Research from 2018 shows that about half of people who have misophonia may also experience autonomous sensory meridian response (ASMR), which is a “euphoric feeling” people feel with certain sounds. People who have more severe reactions to their misophonia triggers may wish to seek out sound therapy. People can also keep noise-canceling headphones nearby to wear when difficult situations occur. There is no cure for misophonia, but there are some measures people can take to lessen the effects, such as avoiding situations they know can be triggering. Sniffling, cracking joints, and tapping can also cause an intense reaction. While feeling upset over chewing sounds is one of the most well-known triggers of misophonia, there are other sounds that may trigger anxiety and annoyance. The Misophonia Institute reports that approximately 20% of the population has misophonia.Īccording to a 2018 study, misophonia is defined as a “condition where patients experience a negative emotional reaction and dislike (e.g., anxiety, agitation, and annoyance) to specific sounds.” The results were recently published in the journal Frontiers in Neuroscience. The scientists discovered which parts of the brain involved in misophonia are associated with tapping sounds, and learned that the parts of the brain that contribute to chewing-related misophonia may be different than previously thought. To learn more about what causes the disorder, researchers at The Ohio State University (OSU) studied people with misophonia and people without misophonia to see what happens in the brain when certain sounds are present. Misophonia, or sound aversion, is a disorder that causes extreme negative reactions to certain noises. The results yielded a surprising discovery that could lead to a better understanding of the disorder.In a new study, scientists used MRI scans to replicate previous misophonia research on chewing to see what happens in the brain with different sound triggers.
