Charcot-Marie-Tooth Disease

Overview

Charcot-Marie-Tooth Disease is a genetic disorder that affects the peripheral nerves. These are the nerves outside the brain and spinal cord that control movement and sensation in the arms and legs. People with Charcot-Marie-Tooth Disease often experience weakness, muscle atrophy, and numbness in their extremities. This can make it difficult for them to walk, run, or use their hands effectively.

The disease is caused by mutations in genes that are important for the function of nerve cells. These mutations lead to problems with the production or structure of proteins needed for nerve function. As a result, the nerves are not able to send signals properly between the brain and muscles. Charcot-Marie-Tooth Disease is a progressive condition, meaning that symptoms tend to worsen over time. Treatment options focus on managing symptoms and maintaining mobility and quality of life for affected individuals.
