视频录像脑电图对癫癎诊断的应用价值

APPLIED VALUE OF VEEG IN DIAGNOSIS OF EPILEPSY

目的:探讨视频录像脑电(VEEG)的睡眠时相与癫癎的关系及其对癫癎病的诊断价值。方法:225例常规脑电(EEG)无痫样放电患者分为癫癎组和可疑癫癎组进行VEEG监测并分析结果。结果:临床癫癎组癎样放电总发生率为59%,,可疑癫癎组总发生率为3%,癫癎样放电主要出现于NREM睡眠Ⅰ-Ⅱ期。结论:睡眠期癎样放电检出率明显高于觉醒期,VEEG可提高癎样放电的检出率,对癫癎的诊断有重要意义。

Objective： To explore the relation of VEEG between sleeping phase and epilepsy, and its diagnostic value for epilepsy. MethodsVEEG was carried out in 225 patients （derided into clinical diagnosed epilepsy group and doubtful epilepsy group） with no epileptiform discharges in routine EEG and findings were analyzed. Results： The positive rate of epileptiform discharges in patients with epilepsy was 59%, and it was 3% in the doubtful epilepsy group. The epileptiform discharges were mainly found in the Ⅰ-Ⅱ stages of NREM sleep. Conclusions： The rate detected of epileptiform discharges during sleep was higher than that during awakening. VEEG might increase the rate detected of epileptiform discharges. It might be of important significance in the diagnosis of epilepsy.
