目的 总结伴有中央颞区棘波的小儿良性癫痫 (BECT)临床和脑电图特点。方法 对 44例本病患儿的临床资料和脑电图进行分析。结果 本组发病年龄为 2～ 12a ,其中 5～ 10a占 79.5 %。 42例发作与睡眠密切相关 ,2例于睡眠和白天觉醒时均有发作。部分性发作 35例中16例伴全身泛化 ,6例伴Todd麻痹。发现时即为全身性发作9例。发作间期脑电图均有一侧或双侧中央和 (或 )中颞区尖波或棘波 ,清醒脑电图阳性率 45 % ,睡眠脑电图阳性率82 .9%。结论 BECT临床发作和睡眠密切相关 ,发作的基本类型为部分性发作 ,部分患儿可伴全身泛化。发作间期脑电图均有一侧或双侧中央和 (或 )中颞区尖波或棘波 ,睡眠脑电图阳性率显著高于清醒脑电图
Objective To summarize the clinical and electroencephalographic features of benign epilepsy (BECT) in children with central temporal spikes. Methods 44 cases of children with clinical data and EEG analysis. Results The onset age of this group was 2 ~ 12a, of which 5 ~ 10a accounted for 79.5%. Seventy-two episodes were closely related to sleep, and two had seizures during sleep and awakening during the day. Partial seizures in 35 cases, 16 cases with generalized generalized, 6 cases with Todd paralysis. Found to be systemic attack in 9 cases. Interictal electroencephalogram Either one or both sides of the center and (or) in the temporal spikes or spikes, the positive rate of 45% of the clear electroencephalogram, sleep EEG positive rate of 82.9%. Conclusion The clinical seizure and sleep of BECT are closely related. The basic type of seizure is partial seizure, and some children may be generalized. Interictal electroencephalogram Either one or both sides of the center and (or) of the temporal spikes or spikes, the positive rate of sleep EEG was significantly higher than the sober EEG
