Sound On For A Sound Mind: Study Links Treatment Of Hearing Loss To Slowdown In Cognitive Decline
Many tend to dismiss the gradual impairment of our senses as part and parcel of the ageing process – as natural as the greying of our hair, or the wrinkling of skin; not as worthy of attention compared to more pressing matters like the onset of chronic illnesses.
Hearing loss affects about one in three seniors over the age of 65.

Results from the recently published Ageing and Cognitive Health Evaluation in Elders (ACHIEVE) study show that treating hearing loss can significantly reduce cognitive decline in older adults by 48% over a three-year period.

This effect was seen in a cohort of 250 adults recruited from an ongoing heart study in the United States, who were older and at a higher risk of getting dementia.
The remaining population of 739 newly recruited adults from nearby communities, who weren’t as likely to get dementia, did not exhibit a similar significant effect. The participants’ ages ranged from 70 to 84.

The ACHIEVE study results show that hearing intervention – treating hearing loss with hearing may help older adults maintain their thinking and memory abilities as they get older, particularly in those groups of older adults at increased risk for cognitive decline.
Why is hearing so crucial in preventing cognitive decline?
We’ve known for over a decade that hearing loss is strongly linked with the risk of dementia and cognitive decline.
However, we didn’t know if treating hearing loss could in fact reduce cognitive decline and potentially lower the risk of dementia.
There are three main mechanisms that may explain why hearing loss may be associated with
Hearing loss is very common in older adults but often goes untreated. Treatment of hearing loss with hearing aids does not carry any health risks.
We recommend that clinicians encourage patients to get their hearing tested, and that people who have concerns about their hearing and their risk factors for cognitive decline discuss these concerns with their doctor and a hearing care professional who can help them address their hearing and communication issues.
