儿童发作性症状与异常放电关系分析

目的：研究儿童发作性症状与异常放电的关系。方法：分析归属明确的１６５例儿童发作性障碍在２４小时监测期间的临床发作和ＡＥＥＧ变化。结果：存在三种关系；异常放电与临床发作时相一致；时相不一致；发作与发作间期均无异常放电。癫痫发作时不一定总能记录到异常放电，非癫痫发作和亦有癫痫样波，癫痫发作可与非癫痫发作并存。结论：使发作性障碍诊断复杂化的因素多种多样，诊断时性能以病史为基础结合ＥＥＧ所见全面分析。

Analysis of the relations between clinical attacks and epileptiform EEG discharge in children with paroxysmal disorder

: To study the relations between the time of clinical attacks and electroencephalogram(EEG ) abnormal discharges. Methods: The simultaneous recordings of the clinical events and the 24 - hourambulatory EEG (AEEG ) of 165 children with paroxysmel disorders who had one or more attacks during the 24hour recording session. were analyzed. Results : The results showed that the clinical events may or may not associatewith the associate synchronous EEG epileptiform activity; and that the EEG recording may be still normal duringepileptic seizure ,hut epileptiform EEG discharges may be recorded in those with nonepileptic seizure. In addition,Epileptic and nonepileptic seizures may coexist. Conclusions: Varied factors made the diagnosis and differentialdiagnosis of paroxymal disorders complex. and comprehesive analysis of the clinical manifestations and EEGchanges combined with illness history and EEG findings should be made when considering to have paroxymaldisorders.[
