儿童额叶性癫痫的临床和脑电图特点

The electroencephalographic and clinical characteristics of frontal lobe epilepsy in children

目的 了解儿童额叶性癫痫的临床和脑电图特点。方法 对２４ 例额叶性癫痫患儿进行临床观察和录像脑电图监测。结果 额叶性癫痫具有强直性姿势性及扭转性发作等多种发作形式，每日平均发作２０ 次，持续时间平均３０ 秒，１８ 例有夜间发作。９１％ 的患儿在录像脑电图监测中出现发作，发作期与发作间期痫样放电率分别为９５％ 和９６％ 。结论 额叶性癫痫发作形式多样，发作频繁，发作持续时间短暂，夜间好发。录像脑电图阳性率高，痫样放电波形多样，易于播散。

Objective Frontal lobe epilepsy (FLE) in children has not been well characterized in China The authors studied the EEG and clinical manifestations in a cohort of 24 children with FLE Methods Clinical manifestations of FLE were recorded and video EEG monitoring was performed on all the 24 patients Results The clinical manifestations of FLE included tonic postural signs and torsive movements et al The average seizure frequency was about 20 times/day Mean duration of episode was 30 seconds Nocturnal seizure was found in 18 patients During the video EEG monitoring, seizures were traceable in 91% patients The epileptic form EEG patterns were found in 95% and 96% of ictal and interictal EEG, respectively Conclusion The clinical manifestation of FLE varied The common features of FLE included high seizure frequency, short duration and nocturnal preponderance There is high positive rate of video EEG in detecting epileptic discharges The epileptic waves varied and spread quickly
