One way to help ward off dementia is to make sure your hearing is as good as possible. Frank R. Lin is director of the Cochlear Center for Hearing and Public Health, Johns Hopkins Bloomberg School of Public Health and professor of otolaryngology, head and neck surgery. He joins Krys Boyd to discuss why we shouldn’t brush off hearing loss as a symptom of old age and the connection between good hearing and cognitive health. His study “Hearing intervention versus health education control to reduce cognitive decline in older adults with hearing loss in the USA” was published in The Lancet.
