If older adults with moderate hearing loss wear hearing aids for three months, they often feel like their daily life gets better and listening to people becomes less tiring.

Even if an older person has worse memory or thinking skills, it doesn’t change how much better they feel or how much easier it is to listen after getting hearing aids — the hearing aids help just as much no matter their brain health.

Older people with moderate hearing loss who wear hearing aids are less likely to develop dementia over seven years than those who don’t—about 5 out of 100 vs. 7 or 8 out of 100—so hearing aids might help protect the brain, even if other factors could be influencing the result.

If you're older and have trouble hearing, using hearing aids might help keep your brain sharper and lower your chances of developing dementia.

For older people with moderate hearing loss, using hearing aids for seven years doesn’t seem to make their memory or thinking skills noticeably better or worse than not using them.

No matter how old you are, if you have hearing loss and use a hearing aid, your age won’t change how well you understand speech or how hard you feel you have to listen.
