青少年肌阵挛性癫(癎)的临床特点及误诊原因分析

目的研究青少年肌阵挛性癫痫（JME）的临床特点及导致误诊的主要原因。方法对61例JME患者的临床和脑电图（EEG）资料进行回顾性分析。结果肌阵孪是最常见的首发症状，其次为肌阵挛加全身强直一阵孪发作（GTCS）。导致误诊最常见的原因是医师对肌阵挛发作缺乏认识，其次是临床和EEG的非对称性表现。结论JME的正确诊断依赖于医师对此综合征的深刻了解，EEG只能作为辅助诊断工具。

Clinical features and misdiagnosis in juvenile myoclonic epilepsy

Objective To study the clinical features and main factors responsible for diagnostic errors in juvenile myoclonic epilepsy (JME).Methods We retrospectively analyzed clinical and EEG data of 61 JME patients referring to our hospital.Results Myoclonous was the most common symptom at the onset,followed by myoclonous plus generalized tonic-clonic seizure(GTCS).Failure to recognize the myoclonous was the most common misdiagnosis factor.Clinical and EEG asymmetries were the second most important cause.Conclusion A correct JME diagnosis is strictly dependent on the knowledge of this frequent epileptic syndrome whereas EEG is just an diagnostic tool.
