The Connection Between Hearing Loss & Dementia

Hearing Loss and Dementia

Were you aware that dementia impacts roughly 55 million individuals around the world, and this number is anticipated to triple by 2050?* In accordance with global research, those with severe hearing loss are estimated to be five times more susceptible to developing dementia.

As we grow older, hearing loss is a prevalent occurrence. However, it's crucial to realise that hearing loss not only impacts our ability to hear, but may also have substantial implications on our cognitive abilities, potentially leading to dementia.

Managing Hearing Loss

The severity of cognitive decline is more likely to increase as hearing problems worsen, and untreated hearing loss can lead to dementia as a possible consequence. A study revealed that older adults with hearing loss had a similar rate of cognitive decline as their normal-hearing peers in 7.7 years and 10.9 years, respectively.

Preventing midlife hearing loss could reduce up to 9% of new dementia cases, which is the highest percentage among all potentially controllable risk factors identified in a commissioned report published in The Lancet in 2017.

How Hearing Loss can lead to Dementia

The correlation between hearing loss and dementia is significant. Experts suggest that hearing loss may contribute to dementia through various means, such as cognitive overload, brain structure, and social isolation.

• Cognitive load - Continuously straining to hear and comprehend puts undue stress on the brain. The resources typically devoted to storing spoken information in memory are instead expended on comprehending it initially.


• Brain structure - Hearing loss could impact the brain's structure, leading to cognitive problems. Imaging studies of older adults with hearing loss show that they have less grey matter in the area of the brain that receives and processes sounds from the ears. Certain brain cell structures may shrink when they don't receive enough stimulation.


• Social isolation - When it becomes difficult to hear and participate in conversations, you may choose to remain at home instead of going out and socializing. However, withdrawing from your friends, family, and activities can lead to reduced social engagement. Insufficient stimulation throughout the day increases the risk of developing dementia.
