How frequently do you contemplate your nervous system? Probably not all that regularly. Generally, you wouldn’t have to worry about how your neurons are sending messages to the nerves of your body. But you will take a closer look when something isn’t working right and the nerves begin to misfire.
One specific disease called Charot-Marie-Tooth Disease which typically affects the extremities can also have a pretty wide-scale impact on the whole nervous system. high-frequency hearing loss can also be triggered by CMT according to some research.
Charot-Marie-Tooth Disease, What is it?
Charcot-Marie-Tooth disease is a set of inherited disorders. The protective sheathing around the nerves fail to function properly due to a genetic disorder.
As a result, the signals sent from your brain to those nerves (and from those nerves back to your brain) don’t travel all that well. Functionally, this can result in both a loss in motor function and a loss of feeling.
CMT can be present in numerous variations and a combination of genetic considerations normally result in its expressions. Symptoms of CMT normally begin in the feet and work their way up to the arms. And, oddly, among those who have CMT, there is a higher rate of occurrence of high-frequency hearing loss.
A Link Between Hearing Loss And CMT: The Cochlear Nerve
The connection between CMT and loss of hearing has always been colloquially established (that is, everyone knows someone who has a story about it – at least inside of the CMT community). And it seemed to mystify people who had CMT – the ear didn’t appear very related to the loss of sensation 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 findings 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 across 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 Treat It
At first, it might be perplexing to attempt to figure out the link between high-frequency hearing loss and CMT. Like every other part of your body relies on properly functioning nerves. Your ears are the same.
What the majority of researchers hypothesize happens is that the cochlear nerve is affected by the CMT – disrupting your ear’s ability to interpret and transmit sounds in a high-frequency range. Some sounds, including some voices, will be hard to hear. Trying to understand voices in a crowded noisy room is especially difficult.
This type of hearing loss is commonly managed with hearing aids. CMT has no renowned cure. Modern hearing aids can provide tremendous assistance in terms of fighting the effects of high-frequency loss of hearing, selecting only those ranges of sounds to amplify. The majority of modern hearing aids can also work well in noisy settings.
Many Reasons For Hearing Loss
Further than the unconfirmed hypothesis, it’s still uncertain what the relationship between high-frequency hearing loss and CMT is. But this kind of hearing loss can be successfully treated with hearing aids. So making an appointment to get fitted for hearing aids will be a smart choice for people who have CMT.
Hearing loss symptoms can occur for numerous reasons. In many situations, loss of hearing is brought about by excess exposure to harmful sounds. Blockages can be another cause. It also looks like CMT is another possible cause.
