The routine EEG study may prove inadequate in selected patients with recurrent and unprovoked seizures. Video-EEG monitoring is an important diagnostic innovation that may be used to confirm the diagnosis of a seizure disorder and classify seizure type. The methodologies and clinical applications of video-EEG monitoring are reviewed. Long-term EEG recordings may be performed as an outpatient or in an epilepsy monitoring unit. Potential techniques for video-EEG monitoring include prolonged conventional routine EEG, ambulatory EEG, and computer-assisted EEG recordings. Periictal SPECT studies performed during long-term EEG recordings in the epilepsy monitoring unit may increase the diagnostic yield of a presurgical evaluation. Video-EEG monitoring is essential for surgical localization in patients with intractable partial epilepsy being considered for a focal cortical resection. The studies may also be necessary to confirm the presence of nonepileptical clinical episodes.
对于某些有反复发作且无明显诱因癫痫发作的患者，常规脑电图检查可能并不充分。视频脑电图监测是一项重要的诊断创新技术，可用于确诊癫痫发作疾病并对发作类型进行分类。本文综述了视频脑电图监测的方法及临床应用。长期脑电图记录可在门诊或癫痫监测单元进行。视频脑电图监测的潜在技术包括延长常规脑电图检查时间、动态脑电图监测以及计算机辅助脑电图记录。在癫痫监测单元进行长期脑电图记录期间同步进行发作期单光子发射计算机断层扫描（SPECT）研究，可能会提高术前评估的诊断率。对于考虑进行局灶性皮质切除术的顽固性局灶性癫痫患者，视频脑电图监测对于手术定位至关重要。这些研究对于确认非癫痫性临床发作的存在也可能是必要的。
