Hearing loss currently affects two-thirds of adults over 60. It’s been theorized that hearing loss affects cognitive function in multiple ways. The first is through lower social engagement due to difficulty communicating. Those with hearing loss tend to pull away from social settings and therefore have less engagement to challenge their brains. Additionally, when the brain is using all its resources to help with hearing, this takes brain power away from thinking and memory abilities, which protect against dementia. Lastly, reduced auditory input to the brain can cause parts of the brain to atrophy, or shrink. Taking all these theories into consideration, treating hearing loss can make a real difference in how our brain ages.
Definition: Dementia
A 2023 study found that hearing aids reduced cognitive decline by nearly 50% in older adults at risk. NIH-funded research compared cognitive function over three years between adults with hearing aids and those in a healthy aging program. Results showed that hearing aid users had improved communication and, among those with dementia risk factors, a 50% slower rate of cognitive decline.
Hearing loss is prevalent and easy to treat – intervention comes at no risk and is an easy way to prevent dementia in many individuals. An added benefit: hearing aids help improve quality of life for people with hearing loss at any age.
