Successful treatment of tardive and spontaneous dyskinesias with corticosteroids.

Three patients, 2 with tardive dyskinesia and 1 with senile chorea, were successfully treated with corticosteroids during an observation period of up to 5 months. Permanent complete relief or pronounced improvement of the dyskinesias was observed at a dosage of 5 mg prednisolone/day. Possible interactions between the putatively hyperactive dopaminergic system and corticosteroids are discussed.
