Researchers at the University of Wisconsin have found a link between hearing loss and mild cognitive impairment. Their study is focused on people who have a parental history with Alzheimer's. Those with hearing loss actually scored poorer on cognitive tests compared to individuals with normal hearing. By identifying and treating hearing loss it may be possible to slow the signs of cognitive decline.
