Abstract: Objective To evaluate the diagnostic value of long-term video EEG (LT-VEEG) in epileptic and non-epileptic seizure disorders.  Methods  The LT-VEEG data of 279 patients who was diagnosed as epilepsy or suspected epilepsy due to paroxysmal events were analyzed retrospectively.  Results  Among 279 cases, 122 cases (43.73%) were detected clinical seizures. Among them, 84 cases who had been found synchronous epileptic discharge in fit period were diagnosed as epilepsy, and 38 cases without synchronous epileptic discharge were diagnosed as non-epileptic seizures. In 157 cases (56.27%) who were not detected seizures, there were 102 cases being monitored interictal epileptiform discharges. In 188 patients who had been monitored epileptic attack or interictal epileptic discharge, 97 cases were identified seizure types, among whom 75 cases were further diagnosed as epilepsy syndrome.  Conclusions  The LT-VEEG has important clinical value in the diagnosis and typing of epilepsy and differential diagnosis with non-epileptic seizures.

摘要： 目的 评价长程视频脑电图对癫痫和非癫痫发作性疾病的诊断价值。方法 对因发作性事件就诊并拟诊为癫痫或可疑癫痫的279 例患者的长程视频脑电图资料进行回顾分析。结果 279 例患者中122 例（43.73%）长程视频脑电图监测到临床发作，其中84 例可见发作期同步样放电而确诊为癫痫发作，38 例发作期无同步样放电而确诊为非癫痫发作；157 例（56.27%）未监测到临床发作，其中102 例可见发作间期样放电。监测到发作期或发作间期样放电的188 例患者中97 例明确癫痫发作类型，其中75 例进一步确定为癫痫综合征。结论 长程视频脑电图在癫痫的诊断、分型及其与非癫痫发作性疾病的鉴别诊断中具有重要临床价值。
