Tardive dyskinesia in northern Israel: preliminary study

Abstract

Tardive dyskinesia (TD) is an iatrogenic syndrome caused by long-term treatment with neuroleptics and is characterized by abnormal involuntary movements in the orofacial region, lingual dyskinesia and in some cases dyskinesia also in the extremities, head and trunk. In the present study we found 20% TD in chronic-neuroleptic-treated patients with a significantly greater prevalence in females (27% of the total population), and a higher frequency in older patients. In males, patients who received electroconvulsive therapy had a significantly lower prevalence of TD. 23 patients had seizures; 7 of these suffered from TD, all of them female.
