Leukodystrophy What is Leukodystrophy Leukodystrophy refers to a group of genetic disorders that are characterized by the imperfect development or maintenance of the white matter (myelin sheath covering nerve fibers in the brain). The myelin sheath is an extremely complex fatty substance made of many components. Each of the leukodystrophies affects one of these components. The most common signs seen in most leukodystrophies include gradual changes in an infant or child who previously appeared well. Changes may appear in body tone, movements, gait, speech, ability to eat, vision, hearing, behavior, memory, or thought processes. The symptoms, which vary according to the specific type of leukodystrophy, may be difficult to recognize in the early stages of the disease. | |
