Tardive dyskinesia

Abstract

Tardive dyskinesia is described as a severe complication of treatment with neuroleptic agents such as butyrophenones and phenothiazines in patients. Earliest manifestations are reported including dyskinesia of the tongue and oral structures. A normal extrapyramidal system physiology is presented along with a comparison of tardive dyskinesia with parkinsonism. Treatment is suggested including prevention, early diagnosis and avoidance of drugs which would exacerbate this condition.
