An 11-year-old male patient developed weakness or right arm elevation after sudden movement at the age of eight. Reflex epilepsy was initially suspected; however, magnetic resonance imaging and electroencephalography (EEG) revealed no abnormality. Video-EEG monitoring was performed, but no change was noted during attacks of weakness. He was diagnosed with paroxysmal kinesigenic dyskinesia (PKD) and carbamazepine has stopped his attacks. PKD is a rare neurological disorder characterized by brief attacks of involuntary movement triggered by sudden voluntary movements, which may be confused with reflex epilepsy. PKD should be considered as a differential diagnosis of reflex epilepsy.
一位 11 岁男性患者在 8 岁时突然运动后出现右臂无力或抬起困难。最初怀疑为反射性癫痫；然而，磁共振成像和脑电图（EEG）均未见异常。进行了视频脑电图监测，但在无力发作期间未观察到变化。他被诊断为阵发性运动诱发性运动障碍（PKD），卡马西平已停止了他的发作。PKD 是一种罕见的神经系统疾病，其特征是短暂的无意识运动发作，由突然的自愿运动引发，可能与反射性癫痫混淆。PKD 应作为反射性癫痫的鉴别诊断。
