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

Do you invest much time considering your nervous system? For the majority of individuals, the answer would probably be not very often. Ordinarily, you wouldn’t have to be concerned about how your neurons are sending signals to the nerves of your body. But when those nerves begin to misfire – that is when something isn’t working properly – you tend to pay much 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. And there’s some evidence that implies that CMT can also lead to high-frequency hearing loss.

What Is Charcot-Marie-Tooth Disease?

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

There is a problem with the way impulses move between your brain and your nerves. A loss in motor function and sensation can be the outcome.

CMT can be present in numerous variations and a combination of genetic factors normally result in its expressions. Symptoms of CMT usually start 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 with CMT.

A Link Between Hearing Loss And CMT: The Cochlear Nerve

There’s always been an anecdotal connection between hearing loss and CMT (which means that inside of the CMT culture everybody has heard other people talk about it). And it was tough to understand the link 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 researchers evaluated 79 people with CMT at the University of Iowa Hospitals and Clinics.

The findings were quite decisive. Low to moderate frequencies were heard very nearly perfectly by those with CMT. But all of the participants showed hearing loss when it came to the high-frequency sounds (usually around the moderate levels). According to this study, it seems pretty likely that CMT can at least be associated with high-frequency hearing loss.

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

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

What the majority of researchers hypothesize happens is that the cochlear nerve is affected by the CMT – disrupting your ear’s ability to translate and transmit sounds in a high-frequency range. Certain sounds, including some voices, will be difficult to hear. Particularly, make out voices in crowded or noisy rooms can be a real obstacle.

Hearing aids are commonly used to manage this kind of hearing loss. CMT has no known cure. Modern hearing aids can give considerable assistance in terms of overcoming the effects of high-frequency hearing loss, isolating only those ranges of sounds to boost. In addition, most modern hearing aids can be adjusted to function well in noisy settings.

Many Factors Behind Hearing Loss

Researchers still aren’t entirely certain why CMT and hearing loss seem to co-exist quite so often (above and beyond their untested theory). But this form of hearing loss can be efficiently treated with hearing aids. So making an appointment to get a fitting for hearing aids will be a smart choice for individuals who have CMT.

Hearing loss symptoms can surface for a wide variety of reasons. Commonly, it’s a matter of loud sound resulting in damage to the ears. In other circumstances, hearing loss may be the result of an obstruction. It appears that CMT can be still another cause of loss of hearing.
