Hearing Aids and Dementia

What is the connection between hearing aids and dementia?

There has been a lot or recent media attention on the link between dementia and people with a hearing loss.

More specifically, attention has focused on how some dementia cases could be prevented with “hearing loss prevention”. Hearing aids in other words.

The link between dementia and hearing loss is strong.


The Lancet reports that hearing impairment is the most prominent risk factor for dementia—midlife hearing loss accounts for approximately 9% of dementia cases. You can read the full report here.

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

Or, in plain 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. However, there does seem to be a clear relationship between auditory processing and global cognitive function in such cases.

Why could this be happening?

When you’re struggling to hear a noise, such as a conversation among your family members in a loud restaurant, your brain is forced to allocate more cognitive resources to help you hear better. This means that noisy or distracting environments can often make it much harder to process auditory stimuli. Over time, the strain on these cognitive functions can contribute to dementia pathology.
