Study Shows How Tests of Hearing Can Reveal HIV’s Effects on the Brain

When comparing the FFR results of 68 HIV-positive adults to 59 HIV-negative adults, the investigators found that the auditory-neurophysiological responses to certain speech cues were disrupted in HIV-positive adults, even though they performed normally on hearing tests—confirming that these hearing difficulties are grounded in the central nervous system.

How Might the Brain Change When We Reintroduce Sound? Interview with Anu Sharma, PhD

New research shows that after wearing professionally fit quality hearing aids, a patient’s brain may “re-organize” its auditory processing centers back towards its original state prior to the hearing loss—with corresponding gains in auditory speech perception abilities and improvements in global cognitive function, executive function, processing speed, and visual working memory performance. Anu Sharma discusses the research findings with Douglas Beck.

Vision and Hearing Loss Associated with Increased Dementia Risk in Older Adults

One study showed having either visual or hearing impairment increased the risk of developing dementia by 11% and Alzheimer’s by 10%, and having both visual and hearing impairment raised the risk of developing dementia by 86% and Alzheimer’s by 112%. Another study demonstrated “testing for changes in multisensory function may help identify those at high risk for dementia.”
