How often do you contemplate your nervous system? Most likely not all that frequently. Normally, 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 specific disease known as Charot-Marie-Tooth Disease which typically affects the extremities can also have a fairly wide-scale affect on the entire nervous system. high-frequency hearing loss can also be the result of CMT according to some research.
What Is Charcot-Marie-Tooth Disease?
Charcot-Marie-Tooth disease is a set of inherited conditions. The protective sheathing surrounding the nerves fail to function properly due to a genetic condition.
There is an issue with how impulses move between your brain and your nerves. A loss in motor function and sensation can be the outcome.
A mixture of genetic elements typically results in the manifestation of symptoms, so CMT can be found in several varieties. For the majority of people who have CMT, symptoms begin in the feet and can work their way up into their arms. And, strangely, 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’s always been an anecdotal connection between hearing loss and CMT (which means that inside of the CMT community everybody has heard others talk about it). And it seemed to confuse people who had CMT – the ear didn’t appear all that related to the loss of feeling in the legs, for example.
A scientific study firmly established the connection just recently when a group of scientists evaluated 79 people with CMT at the University of Iowa Hospitals and Clinics.
The results were rather decisive. Low to moderate frequencies were heard nearly perfectly by those with CMT. But all of the individuals showed hearing loss when it came to the high-frequency sounds (usually across the moderate levels). high-frequency hearing loss, according to this study, is likely to be associated with CMT.
What is The Cause of Hearing Loss And How Can it be Addressed?
The connection between high-frequency hearing loss and CMT could, at first, seem puzzling. Like every other part of your body relies on correctly functioning nerves. Your ears are no different.
The theory is, CMT affects 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 some sounds, including people’s voices. Notably, make out voices in crowded or noisy rooms can be a tangible challenge.
Hearing aids are commonly used to treat this type of hearing loss. There’s no recognized cure for CMT. Modern hearing aids can isolate the exact frequencies to boost which can offer appreciable assistance in battling high-frequency hearing loss. In addition, most modern hearing aids can be calibrated to work well within noisy environments.
There Can be Various Causes For 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 kind of hearing loss can be effectively managed using hearing aids. That’s why countless individuals who have CMT will take the time to sit down with a hearing care professional and get fitted for a custom hearing aid.
Hearing loss symptoms can arise for a wide variety of reasons. In some cases, loss of hearing is brought about by excess exposure to damaging sounds. In other circumstances, loss of hearing could be the result of an obstruction. It turns out that CMT can be still another reason for loss of hearing.
