This report describes studies showing that giving hard of hearing older patients hearing aids reduced memory loss, as did cataract surgery in another study. It makes sense that more sensory input keeps the brain connections active. There are a number of studies with similar results.
As I get older, I’m intrigued by aging. People of the same chronological age can have dramatically different health profiles, activity levels, and intellectual capabilities. Why? Certainly genetics plays a role, as does diet, physical activity, smoking, alcohol intake, and many factors not yet understood. Yet despite our best efforts, we all eventually die. I think the goal should be compression of morbidity, that is, living full and active lives until one gets sick and dies relatively quickly.
That we have treatment of medical problems is great, but prevention is better. This applies to hearing and vision, too.
Avoiding loud noise prevents noise-induced hearing loss, the most common cause of hearing loss in the U.S. and probably in the developed world. There’s some evidence that what is called age-related hearing loss is really noise-induced hearing loss. And cataracts can largely be prevented by avoiding sun exposure and wearing sunglasses when outside.
But there’s no excitement in prevention, and little if any profit to be made for pharmaceutical companies, doctors, and hospitals. So the obviously better option–preventing damage to sight and hearing in the first place–is given short shrift.
Until prevention prevails, make sure your elderly relatives have their hearing and sight checked–hearing aids and cataract surgery might help prevent dementia.
