Do you invest much time thinking about your nervous system? Most likely not all that frequently. Generally, you wouldn’t have to be concerned about how your neurons are communicating signals to the nerves of your body. But you will pay more attention when something isn’t working right and the nerves start to misfire.

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

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 a problem with how impulses move between your brain and your nerves. Functionally, this can cause both a loss in motor function and a loss of sensation.

A mix of genetic elements typically leads to the expression of symptoms, so CMT can be found in a few variations. Symptoms os CMT normally begin in the feet and work their way up to the arms. And, high-frequency hearing loss, curiously, has a high rate of occurrence in those who have CMT.

A Connection Between Hearing Loss And CMT: The Cochlear Nerve

There’s always been an anecdotal connection between loss of hearing and CMT (meaning that within the CMT community everybody has heard others talk about it). And it was tough to recognize the connection between loss of sensation in the legs and issues with the ears.

The connection was firmly established by a scientific study just recently when a group of scientists 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 with CMT. But high-frequency sounds (in the moderate region in particular) were easily heard by all of the participants. high-frequency hearing loss, according to this study, is likely to be connected to CMT.

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

The connection between high-frequency hearing loss and CMT might, at first, seem puzzling. But everything in your body, from your eyebrows to your toes, relies on the proper functioning of nerves. That also goes for your ears.

The theory is, CMT affects the cochlear nerve so sounds in the high-frequency range aren’t able to be translated. Certain sounds, including some voices, will be hard to hear. Trying to hear voices in a crowded noisy room is particularly difficult.

This form of hearing loss is usually treated with hearing aids. There’s no recognized cure for CMT. Modern hearing aids can offer considerable assistance in terms of fighting the effects of high-frequency loss of hearing, selecting only those ranges of sounds to boost. Also, most modern hearing aids can be calibrated to function well inside of noisy conditions.

There Can be Various Causes For Hearing Loss

Further than the untested hypothesis, it’s still not well understood what the link between high-frequency hearing loss and CMT is. But this form of hearing loss can be efficiently treated with hearing aids. That’s why lots of people who have CMT will make time to get a consultation with a hearing care specialist and get a fitting for a custom hearing aid.

There are a variety of causes for hearing loss symptoms. Frequently, it’s a matter of loud noise leading to injury to the ears. Blockages can be yet another cause. It also appears that CMT is another possible cause.
