伴中央颞区棘波儿童良性癫痫的脑电图分析

Analysis of EEG of benign epilepsy in childhood with centrotemporal spikes

目的探讨伴中央颞区棘波儿童良性癫痫(BECT)患儿的脑电图特征和临床意义。方法选择2013年6月至2014年7月BECT患儿22例,分析其脑电图表现及发作时间。结果 22例全部在睡眠中出现癫痫样波,在清醒描记时出现15例;癫痫样波仅出现在中央和(或)颞区者17例,除见于中央、颞区外亦散在性出现于其他脑区者5例;左侧中央颞区明显者9例,右侧中央颞区明显者8例;晚上睡眠发作者10例,中午睡眠发作2例,晨起觉醒前发作者2例,晚上和觉醒前均有发作者8例。结论 BECT是一种特殊癫痫综合征,预后良好,认识其临床和EEG演变的特点及规律可提高对BECT的检出率。

Objective To investigate the EEG features and clinical significance of benign epilepsy in childhood with centro- temporal spikes（BECT）. Methods From June 2013 to July 2014, twenty two patients with BECT were selected, EEG features and seizure time were analyzed. Results All of 22 cases in the sleep epilepsy wave, there were 15 cases in EEG when awak- ened, 17 cases to only appear at central and （or） temporal region, 5 cases to appear in same time at other brain regions, 9 cases obvious at left side of the temporal region, 8 cases in right side of that, 10 cases of seizure in night sleep, 2 cases in noon sleep, 2 cases before awakening, 8 cases at night and before awakening. Conclusion BECT is an age-related epilepsy syndrome. It can increase the correction rate of diagnosis to know the clinical and EEG characteristics and roles of BECT.
