录像脑电图监测并暗示诱发试验对儿童癔症的诊断价值

Value of suggestive provocative test combined with Video-EEG recordings of hysteria diagnosis in children

目的:寻找鉴别儿童癔症性发作与癫癎发作的有效方法。方法:对52例7-14岁发作性疾病患儿进行录像脑电图监测并行暗示诱发试验。结果:癔症组、抽搐原因待查组、癔症合并癫癎组和癫癎组儿童中暗示诱发试验阳性率分别为94％(17／18)、62％(9／14)、38％(3／8)和0(0／12),其中癔症组的阳性率明显高于癔症合并癫癎组,差异有极显著意义(X2=9．49,P<0．01)。各组记录到发作间期癎样放电分别为1、6、7、11例。结论:录像脑电图监测并行暗示诱发试验可能是鉴别儿童癔症与癫癎发作的一种有效试验方法。

Objective; To differentiate the hysteria seizures from epileptic seizures in children. Methods： Video-EEG with suggestive provocative test was performed in 52 patients aged 7- 14 with hysteria. They were divided into four groups： Group 1 （18 patients） who had a definite diagnosis of hysteria; Group 2 （14 patients） who had seizures with unknown causes; Group 3 （8 patients） who had a definite diagnosis of hysteria combined with epilepsy; Group 4 （12 patients） who had a definite diagnosis of epilepsy. Result： The positiveness rate of suggestive provocative test was 94 %, 62 %, 38 %, 0 in Group 1-4 respectively. The positiveness rate in the hysteria group was obviously higher than in the hysteria-epilepsy group（x^2= 9.49, P〈0.01 ） . 1,6,7,11 cases were captured the patients with interictal epileptiform discharge in Group 1-4 respectively. Conclusion： The suggestive provocative test combined with Video- EEG would be an effective means to distinguish hysteria from epilepsy in children.
