Having Trouble Hearing? It May Be A Sign Of Dementia Later In Life

When you think of dementia pathology, you likely think of genetics first (e.g., the APOE4 gene and Alzheimer’s disease risk).

Next, you may consider modifiable lifestyle habits that can help prevent the disease or its progression—like a well-balanced diet, physical activity, stress management, and restful sleep. 

While we typically associate hearing problems with natural aging, they can be a red flag for cognitive issues to come. According to The Lancet, hearing impairment is the most prominent risk factor1 for dementia—midlife hearing loss accounts for approximately 9% of dementia cases2.

While research into why and how these conditions are linked is ongoing, scientists theorize that neuronal mechanisms related to hearing loss can play a role in and exacerbate dementia pathology—and vice versa. 

In other words, in cases where dementia patients also have hearing loss, the science isn’t definitive on whether dementia exacerbates hearing loss or hearing loss can directly lead to dementia.

First and foremost, protecting your hearing health is critical. When you’re struggling to hear a noise (e.g., a conversation among your family members in a loud restaurant), your brain is forced to allocate additional cognitive resources to help you hear better.

This means that noisy or distracting environments can make it even more difficult to process auditory stimuli. Over time, the strain on these cognitive functions can contribute to dementia pathology.

If you’re already struggling with hearing loss, consider speaking to your doctor about a hearing aid. While they don’t cure your hearing problems, they do amplify noises—which, in turn, ensures that your cognitive resources don’t become depleted. Avoiding loud, noisy environments (like concerts) or taking extra precautions (like using ear plugs) can also help protect your hearing capabilities.
