How frequently do you think about your nervous system? Probably not all that regularly. Usually, you wouldn’t have to be concerned about how your neurons are sending messages to the nerves of your body. But when those nerves start to misfire – that is when something fails – you begin to pay a lot more attention to your nervous system.

One particular disease known as Charot-Marie-Tooth Disease that generally affects the extremities can also have a fairly wide-scale impact on the entire nervous system. high-frequency hearing loss can also be triggered by CMT according to some research.

What Is Charcot-Marie-Tooth Disease?

Charcot-Marie-Tooth disease is a set of inherited conditions. In essence, these genetic conditions cause something to go wrong with your nerves or with the protective sheathing around your nerves.

There is an issue with how impulses travel between your brain and your nerves. Functionally, this can lead to both a loss in motor function and a loss of sensation.

A mixture of genetic factors typically results in the appearance of symptoms, so CMT can be present in a few variations. For many people who have CMT, symptoms start in the feet and go up into their arms. And, oddly, among those who have CMT, there is a higher rate of occurrence of high-frequency hearing loss.

The Cochlear Nerve: A Link Between CMT and Hearing Loss

There has always been an anecdotal connection between loss of hearing and CMT (which means that within the CMT culture everyone has heard others talk about it). And it was hard 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 researchers evaluated 79 people with CMT at the University of Iowa Hospitals and Clinics.

The findings were quite conclusive. Low to moderate frequencies were heard very nearly perfectly by those who had CMT. But all of the participants showed hearing loss when it came to the high-frequency sounds (usually around the moderate levels). high-frequency hearing loss, according to this study, is likely to be connected to CMT.

The Cause of Hearing Loss and How to Treat It

At first, it may be perplexing to attempt to figure out the connection between high-frequency hearing loss and CMT. Like all other parts of your body rely on correctly functioning nerves. Your ears are the same.

The theory is, CMT affects the cochlear nerve so sounds in the high-frequency range aren’t able to be interpreted. Anybody with this form of hearing loss will have difficulty hearing some sounds, including peoples voices. Particularly, understand voices in crowded or noisy rooms can be a real obstacle.

Hearing aids are commonly used to deal with this kind of hearing loss. CMT has no renowned cure. Modern hearing aids can select the precise frequencies to amplify which can give significant help in combating high-frequency hearing loss. Additionally, most modern hearing aids can be calibrated to work well within noisy conditions.

Hearing Loss Can Have Many Causes

Beyond the unconfirmed theory, it’s still uncertain what the connection between high-frequency hearing loss and CMT is. But this form of hearing loss can be efficiently addressed with hearing aids. That’s why many people with CMT will make time to sit down with a hearing care professional and get fitted for a custom hearing aid.

Hearing loss symptoms can develop for numerous reasons. Frequently, it’s an issue of loud sound causing damage to the ears. Obstructions can be another cause. It also looks as if CMT is another possible cause.
