In recognition of Dementia Action Week, hearing aid provider, Oticon, explained why successfully addressing hearing loss could reduce the risk of early on-set dementia. For some time, it has been suspected that hearing loss and dementia are linked, and now two new studies have demonstrated a possible connection. These findings provide new evidence supporting the theory that actively wearing aids, to help ease and encourage social interaction, has the potential to delay cognitive decline. Hearing loss was recently reported as the #1 modifiable risk factor contributing to dementia in a study authored by the Lancet commissions on Dementia Prevention, Intervention, and Care. In fact, the research shows that effective treatment for hearing loss may reduce the risk of dementia by a significant 9%. That’s greater than quitting smoking (5%), getting treatment for depression (4%), exercising more (3%) and being free of the “dementia gene” ApoE4 (7%).

Hearing loss is the no.1 modifiable risk factor contributing to dementia  

This was backed by further research published this year which confirmed strong links between hearing status and the risk of disability, dementia, and depression in older adults. The 25-year study, which looks at the effects of hearing problems on health, concludes that untreated hearing loss can increase the risk of developing dementia by 21%.

Most people would associate hearing with their ears, when in fact, better hearing starts with your brain. The brain manages sound and converts it into information that is comprehendible, however hearing loss makes this process more demanding, especially in environments where there are lots of people speaking and background noise complicates the soundscape. Hearing loss essentially puts extra load on the brain as it works harder to ‘understand’, and without effective management can make a person feel tired, disengaged, even unmotivated. 

Being socially active enables us to exercise and enhance our cognitive ability, keeping the brain healthy and active for longer. People who are hard of hearing often find social engagement challenging because of the side effects of the effort to hear and understand speech and would rather choose to avoid them. Unfortunately, this can lead to social withdrawal and isolation, effectively starving the brain of stimulation and potentially accelerating dementia. 

“Hearing loss is a health condition which affects over 5% of the global population” said Thomas Behrens, Chief Audiologist at Oticon. “Sadly, many are living with their hearing loss completely unaware of the adverse effects that it could be having on their overall health. Socialising at family dinners, and on nights out with friends, is a great way to exercise the brain and could help reduce the risk of cognitive conditions, including dementia, especially in later life. Hearing well not only makes interaction possible, but also more enjoyable.”
