Charcot-Marie-Tooth disease, known as CMT, is a neurological disorder that damages peripheral nerves that are responsible for sensations such as pain and touch, according to the Muscular Dystrophy Association. CMT is named after Jean-Martin Charcot, Pierrre Marie and Howard Tooth, the three physicians who first identified the disease in 1886.
CMT is one of the most common hereditary neurological disorders, notes the National Institute of Neurological Disorders and Stroke. It affects about one in 2,500 in the United States. Other names for the disorder include HMSN, or hereditary motor and sensory neuropathy, and peroneal muscular atrophy.
As of 2015, there are no known treatments to stop the progression of CMT, according to the Charcot-Marie-Tooth Association. Physical and occupational therapies may help improve and maintain muscle strength and coordination.
