目的：本前瞻性研究的目的是比较睡眠剥夺脑电图（EEG）与计算机辅助16通道动态EEG在具有癫痫病史信息但初始常规EEG正常或非诊断性的患者中的有用性。方法：46例患者同时进行30-60 min睡眠剥夺脑电图和计算机辅助24 h动态脑电图。每个EEG都被分配了一个编号，并由两名委员会认证的脑电图师独立审查发作间期癫痫样放电和癫痫发作的存在。结果如下：剥夺睡眠的脑电图和动态脑电图改善检测癫痫样放电的相似的金额（24%对33%），然而，动态脑电图检测到癫痫发作的7/46（15%）的患者，和3例癫痫发作仅由计算机检测。结论：我们的结论是，计算机辅助动态脑电图提供了更大的好处比睡眠剥夺记录，因为除了检测发作间期癫痫样放电，它也可以捕捉癫痫发作。意外癫痫发作的发现可以显著影响临床管理。(C)1998 Elsevier Science B.

Purpose: The objective of this prospective study was to compare the usefulness of a sleep-deprived electroencephalogram (EEG) versus a computer-assisted 16-channel ambulatory EEG in patients with historical information consistent with epilepsy but with a normal or non-diagnostic initial routine EEG. Methods: A total of 46 patients had both a 30-60 min sleep-deprived EEG and a computer-assisted ambulatory 24 h EEG. Each EEG was assigned a number and reviewed independently by two board-certified electroencephalographers for the presence of interictal epileptiform discharges and seizures. Results: Both the sleep-deprived EEG and ambulatory EEG improved detection of epileptiform discharges by a similar amount (24% versus 33%); however, the ambulatory EEG detected seizures in 7/46 (15%) patients, and in three patients the seizures were solely detected by the computer. Conclusions: we conclude that the computer-assisted ambulatory EEG offers greater benefit than a sleep-deprived recording because in addition to detecting interictal epileptiform discharges, it may also capture seizures. The discovery of unsuspected seizures can significantly impact clinical management. (C) 1998 Elsevier Science B.V. All rights reserved.
