Can char-co marie tooth disease (cmt) disable a person?

Yes: Charcot-marie-tooth is one of the most common nerve-related disorders passed down through families (inherited). Charcot-marie-tooth disease slowly gets worse. Genetic counseling and testing is advised if there is a strong family history of the disorder.

Highly variable: The spectrum of CMT varies in terms of age of onset, type of heredity, and characteristics of nerve pathology. If the coverings of the nerve only are involved, outcome better than if the central axon involved. An EMG study would be very helpful regarding this prognosis. However, several subtypes are known and there is a broad spectrum of severity. See a neuromuscular expert at local med school.
