电视录相脑电监测在小儿癫痫诊断中的应用

目的评价电视录相脑电图（Ｖｉｄｅｏ－ＥＥＧ）监测在小儿癫痫诊断中的应用价值。方法对２０３例具有发作性症状的患儿进行连续６小时的包括清醒、睡眠、诱发试验及必要的认知测验的Ｖｉｄｅｏ－ＥＥＧ监测。结果经发作期Ｖｉｄｅｏ－ＥＥＧ监测证实，６０例初诊为癫痫性发作的患儿中，２１例（３５％）为非癫痫性发作；２８例其他症状发作中，２４例（８６％）为非癫痫性发作。１０２例痫样放电患儿中８２例（８０．４％）确定了发作类型，３５例（３４．３％）确定了癫痫类型。Ｖｉｄｅｏ－ＥＥＧ监测可发现短暂轻微的癫痫发作及痫样放电引起的一过性认知损伤的表现。结论Ｖｉｄｅｏ－ＥＥＧ在排除非癫痫性发作、确定癫痫性发作的类型、评价脑电－临床关系方面可提供准确可靠的证据，可进一步提高癫痫的临床诊断水平

Video EEG monitoring in diagnosis of epilepsy in childhood

Objective To evaluate the significance of Video EEG in diagnosis of epilepsy in childhood.Methods Video EEG monitoring under the state of awaking and sleeping and with evoked tests and congnitive tests, was performed continuously for 6 hours in 203 children with episodic symptoms.Results Twenty one of 60 children (35.0%) whose episodes had been diagnosed as epileptic seizures were identified as non epileptic attacks by ictal Video EEG. Twenty four of 28 cases (85.7%) with other seizures were identified as non epileptic attacks. Seizure types were defined in 82 of 102 children (80.4%) with epileptic discharges, and epilepsy or epileptic syndromes were defined in 35 of them (34.3%). Some of slight seizures or transient cognitive impairment caused by discharges could be identified by Video EEG reviewing. Conclusions Video EEG can provide accurate and reliable information in diagnosis and classification of epilepsy and also improve the level of diagnosis of epilepsy.
