Among the roughly 40 million adults in the U.S. who have hearing loss, most don’t use hearing aids. This means they may be missing out on more than just good hearing.

Research shows hearing loss, if left untreated, can increase the risk of frailty, falls, social isolation, depression and cognitive decline. One study from scientists at Johns Hopkins University found that even people with mild hearing loss doubled their risk of dementia.

Now a new study finds that restoring hearing loss with hearing aids may lengthen people’s lives.
