Some people are bothered by common sounds that don’t bother others, such as noise from chewing. The technical name for this disorder is “misophonia.”
For many years, misophonia has been thought to be a psychological problem, but new research shows that the problem may be neurological in origin. People with misophonia have differences seen on brain scans from those without misophonia.
Medical science is replete with examples of diseases thought initially to be due to psychological causes, but later found to have biological bases. For example, stomach ulcers were long thought to be caused by stress, with a contribution from spicy food or alcohol, but then they were found to be caused by bacteria.
In the auditory field, hyperacusis–a sensitivity to sound, in which noises that don’t bother others are perceived as painful by those with this condition–was also long thought to be psychological. Then researchers found pain fibers in the auditory nerves, and the biological basis of this condition was better understood.
So kudos to the researchers studying misophonia. For those who suffer from this disorder, having the science world focus on identifying the biological basis for the problem may be the first step to treating it.
