具有中央-颞区棘波的儿童良性癫痫临床及脑电图特点

目的 总结具有中央一颞区棘波的儿童良性癫痫(BECCT)的临床及脑电图(EEG)特点。方法 对78例BECCT患儿的临床资料和脑电图进行回顾性分析。结果 发病年龄3-14a，其中5～10a发病者62例(80％)；发作频度变异大，以短期发作数次者及偶发者为主，占67％(67／78)；72例(92．3％)发作与睡眠密切相关；部分性发作63例(80．8％)，其中继发全身性发作者24例，发现时即为全身性发作15例(19．2％)；发作间期脑电图可见一侧或双侧中央和／或中颞区有尖波或棘波发放，清醒脑电图阳性率55．4％，睡眠脑电图阳性率92％；绝大多数患儿应用抗癫痫药物(AEDs)治疗疗效满意，占93．2％(69／74)，但发作停止≥1年者复查EEG仅部分恢复正常。结论 BECCT是一种与睡眠密切有关的部分性癫痫，发作的基本类型为部分性发作，部分患儿可伴有全身泛化，脑电图为中央、颞区局灶发电，脑电图睡眠诱发试验可提高脑电图辅助诊断的阳性率。本病预后良好，早期诊断有助于对患儿的良好预后尽早做出判断，从而减轻患儿及家庭的心理负担。

Clinical and EEG Characteristics of Benign Epilepsy of Childhood with Centro- temporal Spikes

Objective To summarize the clinical and EEG characteristics of benign epilepsy of childhood with centro-temporal spikes(BECCT). Methods The clinical and EEG data of 78 children with BECCT were retrospectively analyzed. Results The onset age of this disease was 3 to 14 years, and 62 patients aged 5 to 10 years(62/78,80%). The seizures of 72 cases(72/78,92.3%)were associated with sleep. 63 cases(73/78,80.8%)were partial seizures, and 15 cases(15/78,19.2%) were generalized seizures. EEG demonstrated that there were sharp or spike waves of interior discharge in the centro-temporal area of one or two sides, 55.4% cases were positive in awake EEG, and 92% cases were positive in sleep EEG. 93.2% cases were responsive to antiepileptic drugs. Conclusion The characteristics of BECCT were as follows: partial epilepsy related to sleep, partial seizure types and sharp or spike waves of EEG in centro-temporal area. EEG sleep induction test could increase positive diagnostic rate of this disease, and the prognosis of this disease was fine. The early diagnosis is helpful for the patients' prognosis, and can alleviate psychological suffering of the patients and their families.
