How frequently do you contemplate your nervous system? Probably not all that frequently. Usually, you wouldn’t have to worry about how your neurons are sending messages to the nerves of your body. But you will take a closer look when something isn’t working right and the nerves begin to misfire.

One specific disease called Charot-Marie-Tooth Disease that normally affects the extremities can also have a fairly wide-scale impact on the overall nervous system. high-frequency hearing loss can also be triggered by CMT according to some research.

Charot-Marie-Tooth Disease, What is it?

Charcot-Marie-Tooth disease is a set of inherited disorders. The protective sheathing around the nerves fail to function properly due to a genetic condition.

As a result, the signals sent from your brain to those nerves (and from those nerves back to your brain) don’t work all that well. A loss of motor function and sensation can be the result.

A mixture of genetic elements usually leads to the appearance of symptoms, so CMT can be present in a number of variations. For most people who have CMT, symptoms start in the feet and can work their way up into their arms. And, high-frequency hearing loss, oddly, has a high rate of occurrence among those with CMT.

A Link Between Loss of Hearing And CMT: The Cochlear Nerve

There’s always been an anecdotal connection between hearing loss and CMT (meaning that inside of the CMT community everyone has heard other people talk about it). And it seemed to mystify people who had CMT – the ear didn’t seem very related to the loss of feeling in the legs, for example.

The connection was firmly established by a scientific study just recently when a group of scientists examined 79 people with CMT at the University of Iowa Hospitals and Clinics.

The findings were quite decisive. Almost everyone who has CMT passed their low and moderate frequency hearing tests with flying colors. But high-frequency sounds (in the moderate region particularly) were effortlessly heard by all of the participants. According to this research, it seems probable that CMT can at least be linked to high-frequency hearing loss.

What is The Cause of Hearing Loss And How Can it be Treated?

The connection between high-frequency hearing loss and CMT could, at first, seem puzzling. Like every other part of your body relies on correctly functioning nerves. That’s also the same for your ears.

The hypothesis is, CMT affects the cochlear nerve so noises in the high-frequency range aren’t able to be translated. Certain sounds, including some voices, will be difficult to hear. Particularly, make out voices in crowded and noisy rooms can be a tangible challenge.

This form of hearing loss is commonly treated with hearing aids. There’s no known cure for CMT. Modern hearing aids can isolate the exact frequencies to amplify which can provide considerable help in battling high-frequency hearing loss. The majority of modern hearing aids can also perform well in noisy environments.

Hearing Loss Can Have Many Causes

Beyond the untested hypothesis, it’s still uncertain what the connection between high-frequency hearing loss and CMT is. But hearing aid tech offers a definite solution to the symptoms of that loss of hearing. So scheduling an appointment to get fitted for hearing aids will be a smart choice for people who have CMT.

There are a range of causes for hearing loss symptoms. In some cases, hearing loss is brought about by undesirable exposure to damaging noises. In other situations, hearing loss could be the consequence of a blockage. It also looks as if CMT is another possible cause.
