Dementia

Association of hearing loss with dementia

This article in JAMA Network Open reports an association of hearing loss with the development of dementia in Taiwan. Similar associations have been reported in the United States.

Prevention of hearing loss and provision of hearing aids might help, but I prefer prevention in the first instance.  After all, prevention is almost always better and cheaper than treatment, especially for auditory disorders, and noise-induced hearing loss is 100% preventable.

So to preserve your hearing and more, avoid loud noise or use hearing protection if you can’t. And remember: if something sounds too loud, it IS too loud.

Better hearing and sight can help keep memory sharper

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.

Can preventing hearing loss now prevent dementia later?

We have written about this report before but important news bears repeating: A study using functional MRI techniques found that relatively young people with very mild hearing loss were using parts of their brain not normally used to try to understand speech. The researchers think that this added stress on the brain now may lead to an increased rate of dementia later.

The relationship between hearing loss and dementia is being studied in many ways. It has long been known that there was a correlation between hearing loss and dementia, with studies showing that people with worse hearing are more likely to develop dementia.

And one large study is trying to see if giving hearing aids to older people with hearing loss prevents dementia.

But it’s a whole lot easier–both a whole lot better, and a whole lot cheaper–to just avoid hearing loss by avoiding loud noise now. Hearing loss, after all, is not an inevitable part of aging.

Remember: if it sounds too loud, it IS too loud.
