Hearing aids show promise for cognitive recovery, but dementia prevention remains unproven

People who live long enough have a high chance of losing some of their hearing as they grow older. By age 60, about one in three adults has presbycusis, an age-related decline in hearing caused by changes inside the ear, including the loss of sensory hair cells and damage to the auditory nerve. Hearing aids can help bring sounds back into reach, making conversations easier to follow and helping older adults stay connected with the people around them. Some studies have found that hearing loss is linked to a higher risk of cognitive decline and dementia.
