儿童非癫癎性发作事件的动态脑电图监测

目的：观察儿童非癫痫性发作事件24h动态脑电图（AEEG）的特点及其诊断意义。方法：对AEEG监测到的121例儿童非癫痫性发作事件临床发作期EEG进行分析，并以常规脑电图（REEG）进行对照。结果：REEG非特异性异常13例10.7%)，AEEG非特异性异常30例，（24.8%），痫样放电3例（2.5%），总异常率27.2%。非特异性异常检出率以偏头痛最高（34.8%），其次为晕厥（23.5%）及睡眠障碍（22.2%）。结论：儿童非癫痫性发作事件AEEG多为正常或非特异性异常，这有助于儿童非癫痫性发作事件的诊断和鉴别诊断。

AEEG monitoring in children with nonepileptic seizures

Objective:To analyze the features of AEEG (24-h EEG)and its diagnostic value in children with nonepileptic seizures. Methods:The ictal EEG of 121 children with nonepileptic seizures detected by AEEG monitoring was analyzed and compared with rountine EEG.Results:Rountine EEG found nonspecific abnormality in 13 patients with an abnormality rate of 10.7% ,However ,nonspecific abnormal EEG was found in 30 ones by AEEG, the abnormality rate was 24.8% and epileptiform discharges were found in 3 ones (2.5%).The total abnormality rate of AEEG was 27.2%.The nonspecific abnormality rate of EEG and the detection rate of epileptiform discharges were the highest in migraine (34.8%) and secondly in syncope (23.5%) and sleepness disorders (22.2%).Conclusions:AEEG in children with nonepileptic seizures might be mostly normal and nonspecific abnormal. It might be helpful in the diagnosis and defferentiatial diagnosis of children's nonepileptic seizures.
