There are many myths circling around about the use of hearing aids, for example, wearing one can make you feel old. Of course, that might be true since one in three individuals over the age of 65 have a type of hearing loss called presbycusis. So many elderly do wear a hearing aid. That’s not the end of the story, though. These days, medical researchers have proven that wearing a hearing aid will actually keep you from feeling your age. To figure out why this happens, you must know more about how the brain works.

Neuroplasticity: What is That?

Neuroplasticity is a complex word that describes how the brain adapts based on the changes around you. Consider this scenario; you spend your morning walking for exercise. Each day, you follow the same path, but one day, you notice a hole blocking your route. Do you stop walking — no, you find a way to change your route, so you can avoid the hole.

The human brain works the same way. There are nerve channels in the brain that allow you do everyday things like take a walk or read a book. When something happens to you like a stroke, for example, the brain needs to find a way to reroute those pathways through neuroplasticity. Your adaptable brain is also how you learn new skills. If you take a tap dance class, for instance, the brain develops new channels called neural pathways to accommodate what you have learned.

Most the time neuroplasticity works perfectly. When someone has a stroke, the original pathways that allow them to speak might be blocked or damaged. The brain reroutes neural routes so that they can relearn language and speech.

When Neuroplasticity Fails

When a person loses their ability to hear, whether it is due to aging, noise exposure or disease, the brain stops getting the electrical signals from the hair cells or gets fewer of them. At that point, it may decide that the area of the brain that manages the hearing is free real estate. It can start to make new pathways in that section that have nothing to do with hearing. The brain attempts to use space efficiently, but it backfires.

A 2015 study conducted by researchers at the University of Colorado would seem to confirm this concept. They did EEG recordings, that’s a tool that measures electrical activity in the brain, on both children and adults with various degrees of hearing loss. They found that functions like vision and touch can actually take over the part of the brain responsible for hearing.

Hearing Loss and Memory Problems

Researchers already know there is a connection between an increased risk of dementia and hearing loss. Studies indicate that an older individual with hearing loss may suffer mental decline 40 percent faster than someone with good hearing. When the brain stops getting signals from the ears, it starts to decline.

It’s not clear why this decrease might happen, but it is possible neuroplasticity causes it. When the brain struggles to pick up sounds that are faint and it has to pull in resources from other critical functions like short-term memories to compensate.

Why Hearing Aids are the Hero of the Story

These problems all have one thing in common, the brain is no longer receiving the electrical signals from the inner ear that allow it to translate sound. For many individuals, merely filtering sound and amplifying it with hearing aids makes that possible again.

A hearing aid will stimulate the brain, so it tries to hear again. When that happens, it can regenerate the necessary cells and develop new neural pathways. That effect can slow the cognitive decline that leads to memory issues and protects short-term memory.

Having a hearing aid will open you up to new opportunities, too, and that strengthens the brain to keep you young. You can watch TV, take classes and learn new things. Remaining mentally active is really the key to feeling like someone half your age. Too often, older people with hearing loss end up isolated because they can’t take part in discussions or understand what is going on around them.

Hearing aids will change how you live and how your brain works. If you are wondering how well you hear these days, it’s time to schedule a professional hearing exam to see if hearing aids will make you feel young again.
