Hearing loss is linked with accelerated cognitive decline in older adults, but the use of hearing aids may help safeguard seniors' memory and thinking skills.

In a study of 137 older adults with major hearing loss, 1139 with moderate problems, and 2394 with no hearing trouble, hearing loss was significantly associated with greater cognitive decline scores at the start of the study and during a 25-year follow-up period. Participants with hearing loss, but not those with hearing loss who used hearing aids, had greater declines in cognitive function during follow-up compared with controls.

The results are published in the Journal of the American Geriatrics Society.
