According to a new study from UK, wearing hearing aids slow dementia by up to 75%.
Scientists believe that keeping older adults engaged and active by adopting these devices can significantly reduce age-related cognitive decline.
They followed the progress of 2,040 individuals between 1996 and 2014, asking them to complete word memory tests at various stages and monitoring the rate of decline before and after getting a hearing aid.
The research team found that while the aids did not halt or reverse cognitive decline, they slowed it down by three-quarters.
The team at the University of Manchester said the strength of the association between hearing aids and mental deterioration meant policy makers should consider hearing and sight loss screening for all older adults.
Dr Piers Dawes said: “These studies underline just how important it is to overcome the barriers which deny people from accessing hearing and visual aids.
“It’s not really certain why hearing problems have an impact on cognitive decline, but I’d guess that isolation, stigma and the resultant lack of physical activity that are linked to hearing problems might have something to do with it.
“And there are barriers to overcome – people might not want to wear hearing aids because of stigma attached to wearing them, or they feel the amplification is not good enough or they’re not comfortable.”
The new research was published in PLOS ONE and the Journal of the American Geriatrics Society.
