To study the usefulness of short-term recording of video electroencephalography (VEEG) as an outpatient procedure with placebo induction (PLIN) and intravenous saline in cases of pseudoseizures (Psz).
Fifty cases of suspected Psz were enrolled. They were divided into 2 groups: Group 1 consisted of patients with frank Psz, Group 2 those where diagnosis was uncertain. VEEG recording was done and 10 ml of saline used for placebo-induction.
Of 50 patients, 24 (48%) were in Group 1 and 26 (52%) in Group 2. Fifteen (30%) had a spontaneous event during VEEG and 33% had an event only on PLIN. The diagnosis was confirmed in 60 %. In 24% of patients anti-epileptic drugs were discontinued.
Short-term monitoring with VEEG using PLIN is a useful initial screening procedure and in patients where it is inconclusive, long term recordings may be done.
研究门诊视频脑电图（VEEG）短期记录联合安慰剂诱导（PLIN）及静脉注射生理盐水在假性癫痫（Psz）病例中的应用价值。
纳入50例疑似Psz患者。将其分为2组：第1组为明确诊断为Psz的患者，第2组为诊断不明确的患者。进行VEEG记录，并使用10ml生理盐水进行安慰剂诱导。
50例患者中，第1组有24例（48%），第2组有26例（52%）。15例（30%）在VEEG检查期间出现自发事件，33%的患者仅在PLIN期间出现事件。60%的患者诊断得到证实。24%的患者停用了抗癫痫药物。
使用PLIN的VEEG短期监测是一种有用的初始筛查方法，对于结果不明确的患者，可进行长期记录。
