Paroxysmal kinesigenic dyskinesia (PKD) is characterized by sudden episodes of involuntary movements. PKD is a very rare movement disorder, and correct clinical diagnosis is often a challenge.
We present the case of a 23-year-old female with PKD. The patient showed episodes of twisting movements for 3 years. The symptoms lasted for about 5-10 minutes and subsided spontaneously. She was diagnosed as having epilepsy, and depressive and anxiety disorders successively. However, her symptoms did not alleviate after taking sodium valproate and antidepressants. Though there were no mutations in her gene, carbamazepine was used for treatment and was effective in controlling her symptoms.
The clinical features of PKD patients are not always typical; therefore, it is important to distinguish PKD from the other subtypes of paroxysmal dyskinesia and psychogenic disorders.
发作性运动诱发性运动障碍（PKD）的特征是突然发作的不自主运动。PKD是一种非常罕见的运动障碍，正确的临床诊断往往具有挑战性。
我们报告一例23岁患有PKD的女性病例。该患者出现扭转运动发作3年。症状持续约5 - 10分钟后自行缓解。她先后被诊断为癫痫、抑郁和焦虑症。然而，服用丙戊酸钠和抗抑郁药后她的症状并未缓解。尽管她的基因没有突变，但使用卡马西平进行治疗并有效控制了她的症状。
PKD患者的临床特征并不总是典型的；因此，将PKD与其他类型的发作性运动障碍和精神性疾病区分开来很重要。
