Leukodystrophy/hair. Yes it has been described with leukodystrophy.
Leukodystrophy. The most common symptom of a leukodystrophy disease is a gradual decline in an infant or child who previously appeared well. Progressive loss may appear in body tone, movements, gait, speech, ability to eat, vision, hearing, and behavior. There is often a slowdown in mental and physical development. Symptoms vary according to the specific type of leukodystrophy, and may be difficult to recognize.
Not a usual feature. However, many medications can induce hair loss, and would expect many leukodystrophy patients to be treated with a variety of medications.
