treatment with metil-prednisolone at dose of 1 gram intravenous, each
24 hours during 5 days followed by prednisone oral at dose of 60 mg/
day, plus 25 mcg/day of thyroxin. After the first month the patient
demonstrate neurological improvement. The irritability and behavior
disorders disappeared and the stereotypic movements also improved.
However, the ataxic signs still persisted.
