Decreased Hearing in Older Adults May Cause Decrease in the Amount of Gray Matter in Auditory Centers of the Brain
Hearing loss is one of the most prevalent health complaints in adults over the age of 60 and a major factor in speech comprehension difficulties. The goal for researchers at the Departments of Neurology and Neuroscience at the University of Pennsylvania in Philadelphia and the Volen National Center for Complex Systems at Brandeis University in Waltham, Massachusetts was to examine the effects of hearing ability on the brain processes supporting spoken language processing in adult humans.
The study, published in The Journal of Neuroscience, utilized functional magnetic resonance imaging (MRI) to monitor activity in the brain while older adult subjects with normal-level hearing for their age listened to sentences that varied in the amount of linguistic comprehension needed to understand them...
