Abstract:

It is difficult to diagnose non-convulsive status epilepticus (NCSE) clinically because of the complicated etiology and various clinical and electroencephalographic features of NCSE without a universally accepted definition. Although the diagnosis of NCSE relies largely on electroencephalogram (EEG) findings, the determination of NCSE on EEG is inevitably subjective, and the EEG changes of most patients is lack of specificity. As the diagnosis of NCSE is related to clinical and electroencephalographic manifestations, diagnostic criteria for NCSE should take into account both clinical and electroencephalographic features, and their response to antiepileptic drugs (AEDs).

Key words: Status epilepticus, Electroencephalography, Review

摘要：

非惊厥性癫痫持续状态病因复杂，临床表现和脑电图特征繁多，目前尚缺乏公认的定义，明确诊断较为困难。脑电图是诊断非惊厥性癫痫持续状态必不可少的工具，已有学者建立了非惊厥性癫痫持续状态脑电图诊断标准，但脑电图的判读具有主观性且大多数患者的脑电图变化缺乏特异性。在实际工作中，结合临床症状与相应的脑电图特征，同时观察二者对抗癫痫药物治疗的反应，是诊断非惊厥性癫痫持续状态的理想方法。
