Can Treating Hearing Loss Protect Your Memory?

Today is World Hearing Day. If you only act on one changeable risk to your thinking this year, this is a strong candidate, and it is one of the least discussed.

Why Would Hearing Affect Thinking?

There are two explanations and they are not mutually exclusive.

The first is effort. If understanding speech takes most of your concentration, there is less left for holding onto what was said. People with untreated hearing loss often describe this as a memory problem, because that is what it feels like.

The second is withdrawal, and it is the one families notice. Following a conversation in a restaurant becomes exhausting, so you go out less. You stop ringing people. Less conversation means less of the mental and social activity that keeps thinking sharp.

Do Hearing Aids Help?

World Health Organization guidance recommends hearing aids as part of reducing dementia risk, which is a meaningful endorsement for a device rather than a drug.

What is harder to say is how much. Trials have been mixed, and the people who benefit most appear to be those at higher risk to begin with. What is not in doubt is that hearing aids help you hear, and that the withdrawal they prevent is real.

How Do You Know If You Should Get Tested?

The usual signs are social rather than clinical. The television is louder than it was. You avoid places with background noise. You ask people to repeat themselves, or you have started nodding along instead.

One more worth knowing: if someone has been told their memory is failing and nobody has checked their hearing, that should be checked first.
