[Clinical picture and course of hereditary extrapyramidal diseases in children].

The report contains a description of the clinical development of hepato-cerebral dystrophy in 11 children and of deformans muscular dystrophy in 7 children. The authors indicate to expressed visceral disorders in patients with hepato-cerebral dystrophy and to positive results in the treatment by thiol preparations. The paper also contains an observation with an inheritance of deformans muscular dystonia of a dominant type. Due to a clinical polymorphism of hepato-cerebral dystrophy and deformans muscular dystrophy in children a possibility of a wide phenocopy of this pathology should be taken into consideration.
