The prevalence of dyskinesia was studied in 4 samples of elderly Chinese people in Hong Kong--a psychogeriatric clinic, a mental hospital, a geriatric day hospital and a senior citizen centre. Research Diagnostic Criteria were used to identify cases of tardive dyskinesia. The overall prevalence of spontaneous dyskinesia was 2.4% and tardive dyskinesia was 25.9%. The rate of spontaneous dyskinesia differs across the study samples and is related to nervous system conditions associated with increased age. On the other hand, the rate of dyskinesia associated with antidepressants may not be significantly different from that of spontaneous dyskinesia.
研究人员在香港的4组老年华人样本中对运动障碍的患病率进行了研究，这4组样本分别来自一家老年精神科诊所、一家精神病医院、一家老年日间医院和一个老年人中心。采用研究诊断标准来识别迟发性运动障碍病例。自发性运动障碍的总体患病率为2.4%，迟发性运动障碍为25.9%。自发性运动障碍的发生率在各研究样本中有所不同，并且与随年龄增长而增加的神经系统疾病有关。另一方面，与抗抑郁药相关的运动障碍发生率可能与自发性运动障碍的发生率没有显著差异。
