Hearing aids slow cognitive decline

By Joe Baker, MA, CCC-A, Hearing Science

Hearing loss intervention can dramatically slow the rate of cognitive decline for people at higher risk. A new study published in September 2023 reveals that hearing aids can slow cognitive decline for those at high risk by as much as 48% over three years.

The cause of this connection is still being researched, but there are several theories. One holds that hearing loss may lead to social isolation and reduced cognitive stimulation, both of which can contribute to cognitive decline. In short, we are more likely to avoid social interactions when we cannot understand people as well as we used to. Once we enter our 50s and 60s, we often start thinking, “Why is everyone mumbling?”

Conversely, people with hearing loss are often misunderstood as having cognitive loss when they simply need hearing aids.

Another theory suggests that with hearing loss, we tend to rely more on the brain’s visual cortex (think lip reading). This encourages auditory neurons to change focus and do the work of visual neurons, which they are not fully qualified to do. It’s like asking an accountant to do the work of a lawyer.

The good news is, hearing aids stimulate the auditory cortex, keeping the brain properly structured and bringing more energy and blood to the brain, keeping it healthier.

The American Speech and Hearing Association (ASHA) recommends all adults over age 50 receive a baseline hearing test, and another test in five years so hearing health can be properly monitored. Medicare covers your annual hearing test as do most insurance companies. If you’ve never had a hearing test—or it’s been a while since you had your last one—it’s a good idea to get on our schedule now.
