Treating your hearing loss can be good for your brain. At least, that’s according to a new study by a team of researchers out of the University of Manchester. These researchers looked at a group of more than 2000 participants over the course of nearly twenty years (1996 to 2014). The attention-getting findings? Treating your hearing loss can slow dementia by up to 75%.
That is not a small number.
That’s a head-turning kind of number. And yet, it’s not all that surprising. That’s not to take away from the importance of the finding, of course–that kind of statistical correlation between hearing loss treatment and the fight against dementia is important and eye-popping. But it aligns well with what we already know: treating your hearing loss is vital to slowing cognitive decline as you age.
What Does This Research on Dementia Mean for Me?
Scientific studies can be confusing and contradictory (should I eat eggs, should I not eat eggs? What about wine? Will drinking wine help me live longer?). The reasons for that are lengthy, varied, and not all that relevant to our discussion here. Because here’s the bottom line: this new research is yet another piece of evidence that suggests untreated hearing loss can lead to or exacerbate cognitive decline–now including dementia.
So what does this mean for you? In some ways, it’s pretty simple: if you’ve been noticing any possible signs of hearing loss, you should go see a hearing specialist soon. And, if the hearing specialist recommends you wear a hearing aid, you should definitely start wearing that hearing aid as directed.
Hearing Aids Help Prevent Dementia – When You Wear Them Regularly
Unfortunately, not everyone falls right into the habit of wearing a prescribed pair of hearing aids. This can be for a variety of reasons:
- The hearing aid doesn’t feel like it fits well (problems with fit can be addressed by your hearing specialist).
- The hearing aid doesn’t feel like it works as advertised (calibration problems can also be addressed by your hearing specialist).
- Voices are difficult to make out (in some cases, it takes time for your brain to adjust to hearing voices again).
- You’re concerned about how hearing aids look (many hearing aid styles are designed to be minimally visible).
Clearly wearing your hearing aids are important to your overall health. If you’re struggling with any of the above, go back to your hearing specialist for an adjustment. Sometimes the solution will take time or patience, but working with your hearing professional to ensure your hearing aids work for you is generally part of the process.
And in light of these new findings, treating your hearing loss is more important than ever. Hearing aids are protecting your hearing health and your mental health–so it’s important to take that treatment seriously.
What’s the Link Between Hearing Aids and Dementia?
So why are these two conditions–hearing loss and dementia–even linked in the first place? Scientists themselves aren’t exactly sure (after all, the study was designed to find correlation not cause–with science, it’s one variable at a time!).
But there are some theories. Let me paint you a picture. Let’s say your hearing is fading. You go out to a restaurant and ask about the menu. The waiter tells you the specials, but the restaurant is loud and you can’t quite understand, so you ask the waiter to repeat. And the same thing happens. It sounds like the waiter is mumbling, for some reason, but that doesn’t make sense. You can tell the waiter is getting upset with you. You can feel people at other tables staring at you.
So you might be a little less likely to go out to dinner, right? You might–if you’re anything like others who suffer from hearing loss–be less likely to out altogether. And that’s the problem: that social isolation can exacerbate hearing loss and cognitive decline issues.
Another theory is that your brain needs stimulation and activity to stay nimble, and auditory signals are part of that stimulation.
Hearing Aids Help Your Brain
Your hearing aid helps you hear better. And that can help keep your brain active, providing a more robust natural defense against dementia and cognitive decline. That’s why a connection between the two seems reasonable–and why hearing loss treatments can slow dementia by up to 75%. Wonder what else you didn’t know about hearing loss?
