According to the latest research from John Hopkins Bloomberg School of Public Health, there were 32% less cases of dementia reported in people with moderate to severe hearing difficulties who used hearing aids to support their hearing loss.
The study was published in the latest Journal of the American Medical Association and was compiled using nationally representative US Medicare datasets from the NHATS (National Health and Aging Trends Study).
Over 2,413 people were analysed for the study, half of whom were aged 80 plus, to look for any correlation between the signs and symptoms of hearing loss and the prevalence of dementia. The findings were staggering, with participants with moderate/severe hearing loss being 61% more at risk for developing dementia than those with normal hearing.
Alison Huang, senior research associate with the Bloomberg School’s Department of Epidemiology says that “the study refines what we’ve observed about the link between hearing loss and dementia and builds support for public health action to improve hearing care access.”
Out of the 853 participants who had moderate/severe hearing loss, hearing aid use was associated with a 32% lower prevalence of dementia, which indicates a direct link between the two.
