Informations about the disease

Clinical Comment

Subacute encephalopathy, confusion, seizures, movement disorder, often after febrile illness; bilateral lesions in basal ganglia in childhood, life-threatening if untreated, symptoms can be reversed/progression prevented by high doses of biotin and thiamine.
