An observational study has found that hearing loss may predict increased cognitive decline in older adults. During six years of follow-up researchers found a 24% higher risk of cognitive deficit in those with hearing loss compared to those with normal hearing. Much more research is needed to understand the mechanisms behind these findings, and whether improving hearing (with hearing aids) would reduce cognitive loss.
PositiveTip: Good hearing hygiene, such as using ear plugs or hearing protecting ear muffs in loud, noisy environments, can help prevent hearing loss.
