Charcot-Marie-Tooth disease CMT is the eponym for non-syndromic inherited neuropathies that affect motor and sensory axons of the peripheral nervous system. The clinical onset may be as early as infancy or childhood or as late as middle age. The genetics of CMT is complicated. Two further complications are that different mutations in the same gene can cause different phenotypes, and that the same phenotype can be caused by mutations different genes. A unifying principle is that both the dominantly CMT1 and the recessively CMT4 inherited forms of demyelinating CMT are caused by mutations in genes expressed by myelinating Schwann cells. Thus, a cell autonomous effect of the mutant gene in myelinating Schwann cells caused demyelination. Similarly, with a few potential exceptions, the dominantly CMT2 and recessively inherited forms of axonal CMT, as well as the related conditions of HMN and HSAN, are caused by mutations in neuronally expressed genes; the mutant gene has cell autonomous effects in neurons. Beginning with the pioneering work of Dyck and colleagues, CMT was separated into type 1 and type 2 Shy et al. Based on their analysis of patients of known genotypes, Kennerson et al.

I grew up in a small town in Texas, where everyone knew everything about everyone. With five generations of CMT in my family, I want to break that chain once and for all. As a recent college graduate pursuing a Ph. Who better to lead a new wave of research than someone with CMT who cares deeply and has a personal connection to the work? My mother was the band director for our local middle and high schools and a leader in the community.
If you have received conflicting advice about the role of exercise in CMT, you are not alone! Not a CMT clinic day goes by without my being asked:. We are not focusing on only one muscle or area of the body. We are looking at the person as a whole with the goal of making gains in mobility, independence and overall well-being. One would not use the same dose of a medication in an adult and a child, or for people who have different symptoms.
Likewise, the exercise program and its methods and objectives must be tailored to each individual based on the type of CMT and several other clinical factors. Exercise for CMT revolves around four modalities: balance, stretching, endurance and strength. Each modality can be considered a piece of a larger puzzle and needs to be combined with the other modalities for optimal results.
Expert guidance from a physical therapist who has experience with CMT is invaluable and should be considered before engaging in any exercise program. Balance problems are nearly universal with CMT. While this problem cannot be easily solved and assistive devices may still be needed, several simple balance exercises exist and can be performed at home.
A chair may be used for support. Tai-chi and modified chair yoga have been shown to help with balance in other diseases. Stretching exercises help prevent pain and loss of range of motion at joints affected by CMT, such as the ankles.

I saw something about invisible disabilities the other day. To me, that means a chronic illness that has flare-ups or any type of disorder that you cannot really see. I have heard people say that Charcot-Marie-Tooth is an invisible disability. Is it noticeable if I am sitting or standing? Probably not at first glance. You may see me stumble or lose my balance when standing for a long period, but that can be chalked up to many different things.
Maybe I was just tired or lost my focus on what I was doing. You may not even notice that I stumbled or had a harder time getting up from the chair. However, once I walk, you will notice that something is not quite right. You will most likely see the awkward gait and unbalanced walk.

Charcot-Marie-Tooth disease CMT is the most common inherited neuromuscular condition, affecting approximately 1 in in every 2, people. It is named after the three neurologists who first described the condition in CMT affects the motor and sensory peripheral nerves. These are the nerves that connect the spinal cord to the muscles, joints and skin and carry messages in both directions. When these nerves do not function properly weakness and wasting of the muscles below the knees and hands occurs.
Many people with CMT also have loss of feeling in the hands and feet. CMT is not in fact a single disorder but a group of conditions that have some similarities. They are genetic conditions and more than 30 different genes have been shown to cause the different types of CMT. Disease onset usually occurs during the first decades of life and gets worse slowly. Severity is highly variable, even within families, but the condition only rarely leads to severe disability. What are the types and causes of Charcot-Marie-Tooth disease?
These DNA errors are within genes that contain the instructions for the production of proteins that are important for the functioning of the peripheral nerves. There are more than 30 different types of CMT, each caused by a mutation in a different gene. However, the main distinction is based on the results of nerve conduction studies which measure the speed that signals travel down the nerves.

CMT is a group of genetic conditions affecting the peripheral nerves, which connect the brain and spinal cord to the rest of the body. It is commonly referred to as hereditary motor and sensory neuropathy HMSN , which refers to its two primary features: it is hereditary and affects the function of the motor and sensory peripheral nerves. The motor nerves carry messages from the brain and spinal cord to our muscles, telling them to contract.
The sensory nerves convert specific external stimuli, such as touch and pain, into signals that are transmitted back to the brain. CMT causes the motor and sensory nerves to become damaged and eventually die.

What would dating be like in a dating app society? What do you talk about on a first date with a stranger? Would men care about the wrinkles forming around my eyes, the sunspots appearing on my chest? And the most anxiety-inducing question of all: would they notice the signs of my neurological disorder? How different is chronic illness dating and finding love with a chronic illness than what it used to be?
Now in my thirties, I was still apprehensive about dating, but eventually, I succumbed to the pressure from friends who said things like:. Adding to the list of things-that-suck-about-dating a genetic disease that makes you walk funny and it was almost too much for me to bear. The first struggle I encountered, basic but consequential, was deciding what shoes to wear.
