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

How often do you contemplate your nervous system? Most likely not all that regularly. Normally, you wouldn’t have to be concerned about how your neurons are sending messages to the nerves of your body. But you tend to take a closer look when something isn’t working right and the nerves begin to misfire.

There’s one specific condition, known as Charcot-Marie-Tooth (CMT) disease, which can influence the nervous system on a fairly large scale, though the symptoms usually manifest primarily in the extremities. high-frequency hearing loss can also be the result of CMT according to some evidence.

Charot-Marie-Tooth Disease, What is it?

Charcot-Marie-Tooth disease is a set of inherited conditions. Essentially, these genetic disorders 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 cause both a loss in motor function and a loss of sensation.

CMT can be found in numerous variations and a combination of genetic considerations normally result in its expressions. Symptoms os CMT usually begin in the feet and go up to the arms. And, strangely, among those who have CMT, there is a higher rate of occurrence of high-frequency hearing loss.

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

The link between CMT and hearing loss has always been colloquially recognized (that is, everyone knows somebody who has a story about it – at least inside of the CMT culture). And it was difficult to understand the link between loss of sensation in the legs and problems with the ears.

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

The results were rather conclusive. Almost everyone with CMT passed their low and moderate frequency hearing tests with flying colors. 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 research, is likely to be linked to CMT.

The Cause of Hearing Loss and How to Deal With It

At first, it could be puzzling to attempt to recognize the link between high-frequency hearing loss and CMT. But everything in your body, from your toes to your eyebrows, relies on the correct functioning of nerves. Your ears are no different.

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

This kind of hearing loss is commonly managed with hearing aids. CMT has no renowned cure. Modern hearing aids can isolate the exact frequencies to boost which can provide considerable assistance in fighting high-frequency hearing loss. In addition, most modern hearing aids can be adjusted to function well inside of noisy surroundings.

Multiple Reasons For Hearing Loss

Experts still aren’t entirely certain why CMT and loss of hearing seem to co-exist quite so frequently (above and beyond their untested hypothesis). But hearing aid technology offers a definite treatment for 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.

Hearing loss symptoms can arise for numerous reasons. Often, it’s a matter of loud noise contributing to injury to the ears. Obstructions can be yet another cause. It also appears that CMT is another possible cause.
