How often do you think about your nervous system? For the majority of people, the answer would probably be not very frequently. Generally, you wouldn’t have to be concerned about how your neurons are communicating messages to the nerves of your body. But when those nerves start to misfire – that is when something isn’t working properly – you begin to pay a lot more attention to your nervous system.
One particular disease known as Charot-Marie-Tooth Disease that typically affects the extremities can also have a pretty 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 disorders. Effectively, these genetic conditions cause something to go wrong with your nerves or with the protective sheathing surrounding your nerves.
This means that the impulses sent from your brain to those nerves (and from those nerves back to your brain) don’t work all that well. A loss in motor function and sensation can be the result.
CMT can be present in numerous varieties and a combination of genetic considerations normally result in its expressions. Symptoms of CMT normally start in the feet and go up to the arms. And, high-frequency hearing loss, curiously, has a high rate of occurrence among those who have CMT.
A Link Between Loss of Hearing And CMT: The Cochlear Nerve
There has always been an anecdotal link between loss of hearing and CMT (which means that within the CMT culture everyone has heard others talk about it). And it was tough to grasp the link between loss of sensation in the legs and issues with the ears.
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 conclusive. Low to moderate frequencies were heard nearly perfectly by those who had CMT. But high-frequency sounds (in the moderate region in particular) were easily heard by all of the individuals. high-frequency hearing loss, according to this research, 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 loss of hearing and CMT might, at first, seem puzzling. But everything in your body, from your eyebrows to your toes, relies on the correct functioning of nerves. Your ears are the same.
What many researchers hypothesize occurs is that the cochlear nerve is impacted by the CMT – disrupting your ear’s ability to translate and convey sounds in a high-frequency range. Anybody with this kind of hearing loss will have a hard time hearing certain sounds, including people’s voices. In particular, make out voices in crowded or noisy rooms can be a tangible obstacle.
Hearing aids are usually used to treat this form of hearing loss. There’s no recognized cure for CMT. Modern hearing aids can isolate the precise frequencies to amplify which can give considerable help in combating high-frequency hearing loss. Most modern hearing aids can also do well in noisy environments.
Many Causes of Hearing Loss
Further than the untested theory, it’s still not well understood what the connection between CMT and high-frequency hearing loss. But this form of hearing loss can be successfully treated using hearing aids. So making an appointment to get fitted for hearing aids will be a good decision for people who have CMT.
Hearing loss symptoms can arise for several reasons. In many instances, hearing loss is brought about by undesirable exposure to harmful sounds. In other situations, loss of hearing could be the result of a blockage. It turns out that CMT can be still another cause of hearing loss.
