The Link Between Hearing Loss & Dementia

Did you know that approximately 55 million people globally are affected by dementia and this figure is expected to triple by 2050?*


International studies estimate that people with severe hearing loss are five times more likely to develop dementia.

As we age, it's common to experience hearing loss. However, it's important to understand that hearing loss not only affects our ability to hear, but can also have significant effects on our cognitive functions, causing dementia. 


Managing hearing loss


As hearing problems worsen, the likelihood of cognitive decline increases, with dementia being one potential effect of untreated hearing loss. In fact, a study found that older adults with hearing loss experienced the same cognitive decline in 7.7 years as their counterparts with normal hearing experienced in 10.9 years.

Addressing midlife hearing loss could prevent up to 9% of new cases of dementia – the highest of any potentially modifiable risk factor identified by a commissioned report published in The Lancet in 2017.

Untreated hearing loss can lead to dementia


The link between hearing loss and dementia is significant. Researchers believe that hearing loss could contribute to dementia in various ways, including cognitive load, brain structure, and social isolation. 

Continuously straining to hear and comprehend puts undue stress on the brain, leading to cognitive problems.

Hearing loss could also impact the brain's structure, with older adults with hearing loss showing less gray matter in the area of the brain that receives and processes sounds from the ears. 

In addition, withdrawing from social engagements due to difficulty with hearing can lead to reduced social engagement, increasing the risk of developing dementia.
