非惊厥性发作性症状的动态脑电图监测

目的:探讨动态脑电图(AEEG)在非惊厥性发作性症状诊断中的价值。方法:对361例临床上常见的非惊厥性发作性症状患者进行24小时AEEG监测,其中128例与自身的普通脑电图(REEG)对照。结果:128例患者的AEEG异常率(82.0％)、痫样放电检出率(60.0％)、临床发作出现率(34.4％),均明显高于REEG(30.5.、7.0％、0)。在361例患者中异常285例(78.9％),检出痫样放电163例(45.2％),而以短暂性意识丧失阳性率最高(54.2％)。根据临床发作与AEEG的关系,诊断癫痫163例,排除癫痫64例。结论:AEEG对非惊厥性发作性症状的诊断及鉴别有重要价值。

AEEG MONITORING IN THE SYNDROME OF NON-CONVULSIVE ATTACK

Objectives: To explore the value of ambulatory electroencephalography (AEEG)in the diagnosis for the syndrome of non-convulsive attack. Methods: AEEG was performed in 361 patients with syndrome of non-convulsive attack and compared with examinations of routine EEG (REEG) in 128 patients. Results: The detection of abnormal rate, epileptiform diacharge and clinocal seizure in 128 patients were apparently higher in AEEG than in REEG (P<0. 001). Epileptiform discharge wea detected in 163 of 361 patients (45. 2%), the detection rate of epileptiform discharge was the highest (54. 2%) in patients with transient loss of consciousness. According to the relations of clinical attack and AEEG, Epilepsy was diagnosed in 163 patients, the diagnosis of epilepsy was excluded in 64 patients. Conclutions: AEEG is of significance for diagnosis of epilepsy and differ-entinl diagnosis of symptom of non-convulsive attack.
