Do you spend much time considering your nervous system? For most individuals, the answer would most likely be not very frequently. Normally, you wouldn’t have to be concerned about how your neurons are sending messages to the nerves in your body. But when those nerves start to misfire – that is when something isn’t working properly – you begin to pay much more attention to your nervous system.

One particular disease called Charot-Marie-Tooth Disease that generally affects the extremities can also have a pretty wide-scale affect on the overall nervous system. high-frequency hearing loss can also be triggered by CMT according to some evidence.

Charot-Marie-Tooth Disease, What is it?

Charcot-Marie-Tooth disease is a set of inherited disorders. The protective sheathing surrounding the nerves fail to function properly due to a genetic condition.

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 outcome.

A mixture of genetic elements usually results in the expression of symptoms, so CMT can be present in several varieties. Symptoms os CMT commonly start in the feet and go up to the arms. And, curiously, among those who have CMT, there is a higher rate of occurrence of high-frequency hearing loss.

The Cochlear Nerve: A Connection Between CMT and Loss of Hearing

There has always been an anecdotal connection between hearing loss and CMT (which means that within the CMT culture everybody has heard others tell stories about it). And it seemed to mystify people who suffered from CMT – the ear didn’t seem very related to the loss of sensation in the legs, for example.

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

The findings were rather conclusive. Almost everyone who has CMT passed their low and moderate frequency hearing exams with flying colors. But all of the participants showed loss of hearing when it came to the high-frequency sounds (usually around the moderate levels). According to this study, it seems probable that CMT can at least be connected to high-frequency hearing loss.

The Cause of Hearing Loss and How to Deal With It

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

The hypothesis is, CMT impacts the cochlear nerve so noises in the high-frequency range aren’t able to be interpreted. Anybody with this form of hearing loss will have difficulty hearing certain sounds, and that includes people’s voices. In particular, understand voices in crowded and noisy rooms can be a real challenge.

This type of hearing loss is commonly treated with hearing aids. There’s no known cure for CMT. Modern hearing aids can select the precise frequencies to amplify which can offer considerable assistance in fighting high-frequency hearing loss. Most modern hearing aids can also perform well in noisy environments.

Many Factors Behind Hearing Loss

Further than the untested hypothesis, it’s still not well understood what the connection between CMT and high-frequency hearing loss. But this type of hearing loss can be effectively managed using hearing aids. That’s why lots of people who have CMT will make time to sit down with a hearing specialist and get a fitting for a custom hearing aid.

Hearing loss symptoms can surface for many reasons. In some situations, loss of hearing is caused by undesirable exposure to harmful sounds. Obstructions can be another cause. It appears that CMT can be still another cause of loss of hearing.
