反射性癫痫的24h脑电图监测

目的探讨反射性癫痫的ＥＥＧ变化。方法对３４例不同类型反射性癫痫在特定刺激下作动态ＥＥＧ监测，以常规ＥＥＧ作比较。结果动态ＥＥＧ异常率（６２％）与痫样放电检出率（５３％）均高于常规ＥＥＧ的３５％与２６％。痫样放电的部位主要涉及到额、前颞。诱发异常占所有动态ＥＥＧ异常的７６％。结论ＡＥＥＧ对提示反射性癫痫是原发还是继发及对预后判断有帮助。

Twenty-four-hour ambulatory EEG monitoring in patients with reflex epilepsy.

Objectives To study electroencephalogram(EEG) changes of reflex epilepsy. Methods Its were summarized that EEG materials of 34 various types of reflex epilepsy patients who performed 24-hour ambulatory EEG(AEEG) monitoring while exposed under special stimulating. Results The results showed that abnormalities rate 62% and the detection rate of epileptiform EEG discharge 53% by AEEG were significantly higher than the abnormalities rate of 35% and 26%by routine EEG.Locations of epileptiform discharge were mainly involved in frontal lobe and anterotemporal lobe.AEEG abnormalities evoked by special stimulating accounted for 76% of overall AEEG abnormalities. Conclusions AEEG changes could indicate whether reflex epilepsy was primary or secondary,and predict prognosis.
