儿童失神癫痫46例脑电图分析

目的：探讨儿童失神癫痫（ CAE）患儿脑电图表现。方法对46例临床确诊CAE的患儿进行脑电图描记。结果46例患儿中有44例（96％）描记到全导两侧对称3 Hz棘慢复合波暴发，其中16例在3 Hz棘慢复合波上描记到多棘慢波，1例同时描记到中央颞区棘波；46例患儿中描记到枕区3 Hz δ活动者34例。结论 CAE患儿一般均具有典型脑电图特征，少数患儿脑电图表现不典型应结合临床注意鉴别。

Study on EEG of childhood absence epilepsy

Objective To investigate the characteristics of electroencephalograms （ EEGs ） of patients with childhood absence epilepsy （ CAE ） .Methods EEG of 46 patients with CAE were analyzed .Results Of 46 patients,there were 44 cases （95.6%） with guided bilateral symmetry 3Hz spike-and-wave.16 cases were character-ized by multiple spike-and-wave on the 3Hz spike and slow wave;and the centrotemporal spikes was found in 1 case. Additionally,the 3Hzδactivity in occipital region has been traced in 34 cases of these 46 patients.Conclusion In general,the EEGs of CAE patients have typical characteristics ,and few of them showed atypical manifestation ,which must be verified by clinical attention .
