150例发作性疾病动态脑电图的诊断价值

Diagnostic value of active-electroencephalogram for 150 cases of paroxysmal events

目的分析150例发作性疾病24h动态脑电图(AEEG),以评估其对发作性疾病的诊断价值。方法对150例发作性疾病常规脑电图(REEG)无痫样放电的患者行24h AEEG检查。结果150例发作性疾病患者中,85例初诊癫痫性发作,经24h AEEG监测60例出现痫样放电(70.58%),非特异性异常7例(8.23%),65例初诊非癫痫性发作中,经24h AEEG监测,12例显示痫样放电(18.46%),6例有非特异性异常(9.23%),150例中共72例有痫样放电(48%)。结论24h动态脑电图对发作性疾病的诊断和鉴别诊断有较高的临床价值。

Objective To analyze and evaluate the significance of the active -electroencephalogram （AEEG） in the diagnosis of paroxysmal diseases. Methods The AEEGs of 150 paroxysmal events with normal route EEGs were examined. Results Among all the 150 cases, 85 and 65 cases were diagnosed epileptic seizures （ES） and non - epileptic seizures （NES） at first, respectively. There were 60 （ 60/85, 70.58% ） cases and 12 （ 12/65,18.46% ） diagnosed as epilepsy in ES group and NES group, respectively. The uncharacteristic abnormality of AEEG were 7（7/85, 8.23% ） and 6 （6/65,9.23%） in ES group and NES group, respectively. 72 cases were diagnosed as epilepsy in the all （72/150,48%）. Conclusion AEEG is a valuable method in the diagnosis and differential diagnosis of paroxysmal events.
