Routine electroencephalogram (EEG) has many limitations, especially the inability to capture reported habitual events in question. A prolonged EEG with synchronized video (video-EEG) overcomes some of these limitations by improving the sensitivity, specificity and the diagnostic yield by attempting to record the habitual events when they are frequent and when indicated. Video-EEG is employed commonly for the diagnosis and classification of epilepsy/epilepsy syndromes, to distinguish between seizures and seizures mimickers, for pre-surgical evaluation and in the management of critically ill children. The duration of recording would vary depending on the indication and frequency of events. Ambulatory EEG is another cost effective and convenient alternative in certain circumstances. However, availability of the machines and expertise, accessibility, affordability and labor intensive nature of the procedure limit widespread use in India. This review explores the role of video-EEG in the management of children with epileptic and non-epileptic paroxysmal events with respect to routine clinical practice in India.
常规脑电图（EEG）有许多局限性，特别是无法捕捉到所询问的习惯性事件。通过尝试在习惯性事件频繁发生且有指征时记录这些事件，同步视频的延长脑电图（视频-EEG）克服了其中的一些局限性，从而提高了敏感性、特异性和诊断效果。视频-EEG 常用于癫痫/癫痫综合征的诊断和分类，以区分发作和发作模拟物，用于术前评估和危重症儿童的治疗。记录的持续时间将根据指征和事件的频率而有所不同。在某些情况下，动态脑电图是另一种具有成本效益且方便的替代方法。然而，机器和专业知识的可用性、可及性、可负担性以及该程序的劳动密集型性质限制了其在印度的广泛使用。本综述探讨了视频-EEG 在管理癫痫和非癫痫阵发性事件中的作用，以及其在印度常规临床实践中的应用。
