目的:探讨24 h长程脑电图(EEG)对婴儿良性癫�(BIE)的诊断价值。方法:对26例临床诊断为BIE的患儿进行24 h长程EEG检查,并对检查结果及随访进行分析。结果:所有患儿EEG背景活动正常,5例(19%)未检测到 EEG异常,21例(81%)共检测到25次异常放电,其中清醒时17次,睡眠时8次。25次异常放电均为局灶起源。2年随访时,所有患儿临床症状消失,23例EEG正常,3例EEG偶示低波幅的小棘波。结论:24 h长程EEG对BIE诊断有重要价值。%Objective:To investigate diagnostic value of the 24‐hour long‐term EEG for infants with benign epilepsy .Methods:To conduct 24‐hour long‐term EEG inspection in 26 infants with benign epilep‐sy in clinical diagnosis and analyze the results of inspection and follow‐up .Results:Background activity of EEG of all infants was normal .Abnormal EEG involving 5 cases (19% ) were not detected .25 abnormal discharges occurred in 21 cases (81% ) including 17 in wakefulness and 8 in sleep .All of 25 abnormal discharges were in focal origin .Through follow‐up visit 2 years later ,clinical symptoms of all cases disap‐peared in 23 cases with normal EEG and 3 cases with EEG of occasional small spike waves of low ampli‐tude .Conclusion:24‐hour long‐term EEG has important diagnostic value for infants with benign epilepsy .
