title: [Therapeutic trial of gamma-vinyl GABA, an inhibitor of GABA transaminase, in tardive dyskinesias induced by neuroleptics].
abstract: Oral gamma-vinyl GABA, an irreversible inhibitor of GABA-transaminase, was given to 10 patients with neuroleptic-induced tardive dyskinesia (7 chronic simple schizophrenics and 3 chronic paranoid schizophrenics). Dyskinesia was reduced in 8 of 10 cases. Aggravation of dyskinesia and major psychomotor sedation was observed in two elderly patients with senile dementia. In addition, with regard to schizophrenic symptoms, gamma-vinyl GABA appeared to have beneficial effects on affective withdrawal and retardation, while hallucinations seemed to be aggravated.
