The oro-facial dyskinesias were totally or significantly relieved in 17 cases. During the active treatment period the involuntary movements of the extremities and dystonic spasms were also significantly relieved in 7 out of 9 patients. In two patients, however, the extrapyramidal symptoms became slightly worse. A significant improvement was noted in the psychiatric symptoms of 14 out of 32 patients during sodium valproate administration. The psychiatric state of 4 out of 32 patients deteriorated. There was no correlation between the serum concentration of sodium valproate and its effect on the dyskinesia or on the psychiatric symptoms. Some of the elderly subjects showed a slight accumulation of the
