Image of a neural disease that would cause high-frequency hearing loss.

How frequently do you think about your nervous system? For most people, the answer would most likely be not very often. Normally, you wouldn’t have to be concerned about how your neurons are communicating signals to the nerves in your body. But you tend to take a closer look when something goes wrong and the nerves begin to misfire.

One particular disease known as Charot-Marie-Tooth Disease that normally affects the extremities can also have a fairly wide-scale affect on the overall nervous system. high-frequency hearing loss can also be the result of CMT according to some research.

Charot-Marie-Tooth Disease, What is it?

Charcot-Marie-Tooth disease is a set of inherited conditions. The protective sheathing around the nerves malfunction due to a genetic disorder.

There is an issue with the way impulses move between your brain and your nerves. A loss in motor function and sensation can be the result.

CMT can be found in several variations and a combination of genetic considerations normally lead to its expressions. For many people with CMT, symptoms begin in the feet and can work their way up into their arms. And, oddly, among those who have CMT, there is a higher rate of occurrence of high-frequency hearing loss.

A Link Between Hearing Loss And CMT: The Cochlear Nerve

There has always been an anecdotal connection between loss of hearing and CMT (which means that inside of the CMT community everybody has heard other people talk about it). And it was tough to understand the link between loss of sensation in the legs and problems with the ears.

A scientific study firmly established the connection 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. Nearly everyone who has CMT passed their low and moderate frequency hearing tests with flying colors. But high-frequency sounds (in the moderate region in particular) were effortlessly heard by all of the individuals. high-frequency hearing loss, according to this research, is likely to be linked to CMT.

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

The connection between high-frequency loss of hearing and CMT could, at first, seem puzzling. Like every other part of your body relies on correctly functioning nerves. Your ears are no different.

What many researchers hypothesize happens is that the cochlear nerve is impacted by the CMT – disrupting your ear’s ability to translate and transmit sounds in a high-frequency range. Anybody with this type of hearing loss will have difficulty hearing specific sounds, including people’s voices. Trying to understand voices in a crowded noisy room is particularly hard.

Hearing aids are commonly used to manage this kind of hearing loss. There’s no recognized cure for CMT. Modern hearing aids can isolate the precise frequencies to boost which can provide appreciable assistance in combating high-frequency hearing loss. The majority of modern hearing aids can also work well in loud environments.

There Can be Various Causes For Hearing Loss

Beyond the untested hypothesis, it’s still uncertain what the relationship between high-frequency hearing loss and CMT is. But this type of hearing loss can be effectively treated using hearing aids. So scheduling an appointment to get a fitting for hearing aids will be a smart choice for individuals who have CMT.

Hearing loss symptoms can arise for a number of reasons. In some cases, hearing loss is brought about by excess exposure to harmful noises. In other cases, hearing loss could be the result of an obstruction. It also looks like CMT is another possible cause.
