Tardive dyskinesia frequently occur during neuroleptic-treatments. Prevalence and risk factors, clinical characteristics, relation to other extrapyramidal disorders are reviewed. The presumed pathophysiology is that tardive dyskinesia are caused by a neuroleptic-induced dopamine receptor hypersensitivity. Several trials of treatment are compared with respect to this hypothesis.
迟发性运动障碍常在抗精神病药物治疗期间出现。本文综述了其患病率、危险因素、临床特征以及与其他锥体外系疾病的关系。推测的病理生理学机制是,迟发性运动障碍由抗精神病药物诱发的多巴胺受体超敏反应所致。针对这一假说,对多项治疗试验进行了比较。
