Do you have trouble remembering everything on your to-do list? Memory and cognitive function often decline with age, although there are steps you can take to preserve your mental acuity. New research indicates that hearing loss can play a large role in how the brain processes information, and, subsequently, how a person performs on cognitive tests. The audiology staff at Glacier Ear Nose & Throat and Glacier Hearing Services in Kalispell, MT, explain the close connection between hearing and cognitive function.

Hearing Loss & Cognitive Decline

Tinnitus & MCI

Tinnitus—a symptom of hearing loss—is something 50 million Americans experience. Ringing, buzzing, and other sounds can be a constant nuisance and heavily impact your quality of life. Coupled with hearing loss, it can lead to isolationism and depression and negatively affect seniors’ lives. Age-related hearing loss is another contributor, with one in three seniors between the age of 65 and 74 living with it.

Mild cognitive impairment (MCI) or decline is something many seniors also deal with, as it affects roughly 15% to 20% of people aged 65 or older. They may have trouble remembering things, making sound decisions, or planning out complex tasks. In some cases, it can lead to more severe forms of dementia.

What’s the Connection?

Seniors living with MCI and hearing loss face a number of challenges, and the effects could accelerate cognitive decline. A study published in the Journal of American Geriatrics Society followed 3,670 seniors aged 65 or older for 25 years. In that time, 137 patients reported significant hearing loss; 1,139 reported moderate hearing loss; and 2,394 reported none. Simultaneously, cognitive skills were tested every few years. Research showed that patients with both hearing loss and MCI experienced decline much more quickly than those with MCI who used hearing aids. 

When the brain can’t process sound, it has difficulty comprehending what’s being said and storing memories. As it tries to compensate, other areas of the brain are overworked, which can lead to forgetfulness, confusion, and other symptoms of MCI. Hearing aids may reduce this issue by keeping the brain balanced.

How Can MCI Be Prevented?

Hearing aids may not only slow cognitive decline, but also possibly delay or prevent the onset of more advanced stages of dysfunction, like dementia. Using a hearing aid also helps people feel more connected with the outside world, communicate with friends and family, and feel more content.
