Do you invest much time considering your nervous system? For most individuals, the answer would most likely be not that often. As long as your body is performing as it is supposed to, you’ve no reason to think about how your neurons are firing or whether nerves are sending proper messages along the electrical pathways in your body. But you tend to pay more attention when something goes wrong and the nerves start to misfire.

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. 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 disorders. Essentially, these genetic conditions cause something to go wrong with your nerves or with the protective sheathing surrounding your nerves.

The result is that the signals sent from your brain to those nerves (and from those nerves back to your brain) don’t progress all that well. A loss in motor function and sensation can be the outcome.

CMT can be found in a number of variations and a combination of genetic factors usually lead to its expressions. Symptoms of CMT normally begin in the feet and go up to the arms. And, oddly, 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

The link between CMT and hearing loss has always been colloquially established (that is, everyone knows someone who has a tells about it – at least inside of the CMT culture). And it seemed to mystify people who suffered from CMT – the ear didn’t seem all that 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 evaluated 79 people with CMT at the University of Iowa Hospitals and Clinics.

The findings were rather conclusive. Nearly everyone who has CMT passed their low and moderate frequency hearing tests with flying colors. But high-frequency sounds (in the moderate region in particular) were effortlessly heard by all of the individuals. 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 Addressed?

At first, it might be puzzling to attempt to figure out the connection between high-frequency hearing loss and CMT. But all of your body, from your eyebrows to your toes, relies on the proper functioning of nerves. That also goes for your ears.

What most researchers hypothesize occurs is that the cochlear nerve is impacted by the CMT – interfering with your ear’s ability to interpret and transmit sounds in a high-frequency range. Anyone with this type of hearing loss will have a hard time hearing certain sounds, including voices. Particularly, understand voices in crowded and noisy rooms can be a real obstacle.

Hearing aids are commonly used to manage this kind of hearing loss. There’s no known cure for CMT. Modern hearing aids can offer significant assistance in terms of overcoming the effects of high-frequency hearing loss, isolating only those ranges of sounds to boost. Also, most modern hearing aids can be adjusted to function well in noisy surroundings.

Multiple Causes of Hearing Loss

Experts still aren’t completely sure why CMT and hearing loss seem to co-exist quite so often (beyond their untested theory). But this type of hearing loss can be successfully managed using hearing aids. So making an appointment to get fitted for hearing aids will be a good choice for individuals who have CMT.

There are numerous causes for hearing loss symptoms. Often, it’s a matter of loud sound causing damage to the ears. Obstructions can be another cause. It also looks as if CMT is another possible cause.
