Charcot (shahr-KOH)-Marie-Tooth disease is a group of hereditary disorders that damage the nerves in your arms and legs (peripheral nerves). Charcot-Marie-Tooth is also known as hereditary motor and sensory neuropathy.
The main signs and symptoms of Charcot-Marie-Tooth disease are muscle weakness and decreased muscle size. You may also notice decreased sensation in affected areas. Foot deformities such as hammertoes and high arches are common in Charcot-Marie-Tooth disease. Symptoms usually begin in your feet and legs, but they may eventually affect your hands and arms.
Muscle weakness and loss of balance can make walking difficult. Symptoms of Charcot-Marie-Tooth disease typically appear in adolescence or early adulthood, but this condition can develop in midlife too.
