Hearing Loss and Dementia
Did you know that hearing loss in midlife can significantly increase your risk of developing dementia later on? It’s true—and the earlier hearing loss begins, the greater the risk.
- And individuals with severe hearing loss are five times more likely to develop dementia
- People with mild hearing loss are twice as likely to develop dementia.
- Those with moderate hearing loss face three times the risk.(Source)
Why does hearing loss affect the brain?
The exact reason isn’t fully understood, but researchers have proposed several possible explanations:
- Depression: Hearing loss can lead to feelings of isolation and depression, which are known risk factors for dementia.
- Cognitive strain: Struggling to hear puts extra stress on the brain, which may affect memory and thinking.
- Social isolation: When people withdraw from conversations due to hearing difficulties, they lose valuable mental stimulation.
While none of these factors alone explain the full connection, they may all contribute to the increased risk.
Common Causes of Hearing Loss
Hearing loss can result from a variety of factors, including:
- Genetics
- Exposure to loud noises
- Diabetes
- Kidney disease
- Head injuries
- Hardening of the arteries
While loud music is often blamed, farming is actually one of the top three occupations linked to hearing loss. Farmers working with heavy machinery should use ear protection such as earplugs, canal caps, or earmuffs. (Hearing Loss Prevention – AgriSafe Network)
Can Hearing Aids Help?
Unfortunately, dementia linked to hearing loss doesn’t appear to be reversible. However, hearing aids can help slow its progression, especially the part caused by hearing loss. Despite this, many people who need hearing aids either don’t realize it or are hesitant to wear them.
Over 40% of people over age 50 have hearing loss, but only a small percentage use hearing aids. Since even mild hearing loss can increase dementia risk, it’s important to get tested by an audiologist and consider hearing aids if needed.
