摘要
目的探讨伴中央—颞棘波灶的儿童良性癫痫的临床和脑电图（ＥＥＧ）特点。方法对１９８６年以来确诊的２４６例患儿的临床和ＥＥＧ资料进行回顾性分析。结果发现所有患儿发作间期都有特征性的ＥＥＧ改变，即在正常的背景活动基础上，中央一中颞区出现成串或单一的高波幅的棘波。这种改变可局限于一侧半球，也可从一侧半球转移至对侧半球或双侧半球。患儿临床上伴面部、半身或全身的强直－阵挛性抽搐。年龄超过１５岁后癫痫发作几乎全部停止。结论ＥＥＧ是诊断本症的根本依据。
Objectives To observe the benign epilepsy of children with centrotemporal spikes. Methods The characteristics of the clinical manifestations and EEG were restrospectively studied in 246 children with benign epilepsy with centrotemporal spikes Results The result showed that all the characteristics of EEG change were noted during seizures,revealing numerous or single slow spikes of high amplitude on the centrotemporal area under the background of the normal activity of the children.The changes could be limitted in unilateral hemisphere and could also move from one side to the opposite side or to both hemisphere.All cases presented facial convulsions or partial/generalized tonic-clonic seizures.The time of clinical seizrures were mainly during sleep(81.7%). The attack ceased after the age of 15. Conclusions EEG is a important diagnostic basis for this disease.
