Over the last decade, research has established strong connections between hearing loss and cognitive decline in older people. Now, a new study presents compelling evidence that hearing aids could actually help slow that decline, especially for people at risk of dementia. Dr. Frank Lin, director of the Cochlear Center for Hearing & Public Health at Johns Hopkins, talks with Stephanie Desmon about the newest research and why the evidence bolsters the case for making sure older adults can (and should) access hearing aids and the support they need about how best to use them.
