About people in the United States have CMT, according to the National Institute of Neurological Disorders and Stroke. It’s named after the three doctors who first described it in 1886. Other names for it are peroneal muscular atrophy and hereditary motor and sensory neuropathy.
5. Complex regional pain syndrome (CRPS)
