In later life, hearing loss can affect our connections with others and is linked with cognitive decline.

As we get older, our hearing plays an important role in keeping us connected to the people and world around us.

Research has linked hearing loss with cognitive decline, and a major trial found that hearing care slowed decline among some older adults at higher risk.

Emma and I recently had our hearing tested. My hearing was ok, but Emma discovered that she would benefit from hearing aids. She now has them, and we were amazed by how many excellent options are available today. Hers are practically invisible—and she can even use them to answer phone calls or listen to audiobooks.

Dr Frank Lin explains what researchers are learning about hearing, social connection and cognitive health.

Arrange a hearing test—even if you haven’t noticed a problem. Hearing checks are inexpensive, widely accessible and well worth doing. They can give you peace of mind or identify a change early, while it is easier to address. Either way, you’ll establish a useful baseline for the years ahead.

Hearing loss is one of the dementia risk factors we can act on. Everyday signs include asking people to repeat themselves, struggling to follow conversations in busy rooms and turning up the television.

Noticing these changes early gives you the opportunity to address a treatable problem. That can make conversations easier now and may also help protect your cognitive health over time.

Our experience reminded me that there is no need to put off a hearing test—or to be daunted by the prospect of hearing aids. Getting tested is simple, and today’s hearing aids can be discreet, highly capable and surprisingly useful.
