非惊厥性发作性症状的动态脑电图监测

Ambulatory electroencephlography monitoring in the syndrome of non-convulsive attack

目的 了解动态脑电图 (AEEG)对非惊厥性发作性症状的应用价值。方法 对 3 68例临床上常见的非惊厥性发作性症状的患者作 2 4hAEEG监测 ,其中 12 9例与其普通脑电图 (REEG)对照。结果 12 9例患者的AEEG异常率、痫样放电检出率、临床发作出现率 (82 .2 %、60 .4 %、3 4.9% )均明显高于REEG组 (3 0 .2 %、7.0 %、0 )P <0 .0 0 1。在 3 68例中共检出痫样放电 166例 (45 .1% ) ,以短暂性意识丧失阳性率最高 (5 3 .9% )。根据临床症状发作与AEEG的关系 ,诊断癫痫 166例 ,排除癫痫 65例。结论 AEEG对癫痫的诊断及非惊厥性发作性症状的鉴别有重要意义。

Objective To explore the value of ambulatory electroencephlography (AEEG)in the diagnosis for the syndrome of non-convulsive attack.Methods AEEG was performed in 368 patients with examinations of non-convulsive attack,compared with examinations of routine EEG (REEG) in 129 patients.Results In the AEEG group,The detection rate of abnormality,epileptic form discharge and clinical seizure were 84.2%,60.4% and 34.9% respeolively,which were significantly higer than that of REEG group (30.2%,7.0% and 0%) respectively ,P<0.001.In total AEEG group epileptic-form discharge were 45.1% (166/368),and were more frequent in patients with transient loss of consiousness (53.9%).With the help of AEEG and related with the clinical attack,epilepsy were diagnosed in 166 patients.and in other 65 patients the diagnosis of epilepsy were excluded.Conclusion AEEG is of clinical significance for the diagnosis of epilepsy and to identify the syndromatic character of non-convulsive attack.
