Long-term EEG in adults includes three modalities: sleep deprived-EEG lasting 1 to 3 hours, 24 hours ambulatory-EEG and continuous prolonged video-EEG lasting from several hours to several days. The main indications of long-term EEG are: syndromic classification of epilepsy; search for interictal discharges when epilepsy is suspected or for the purpose of therapeutic evaluation; positive diagnosis of paroxysmal clinical events; and pre-surgical evaluation of drug-resistant epilepsy. Sleep deprived-EEG and ambulatory-EEG are indicated to detect interictal discharges in order to validate a syndromic classification of epilepsy when standard EEG is negative. These exams can help in evaluating treatment efficacy, especially when clinical evaluation is difficult. Long-term video EEG is indicated for drug-resistant epilepsy, to analyze electro-clinical correlations in a pre-surgical evaluation context, and to refine a positive diagnosis when paroxysmal clinical events are frequent.
持续1至3小时的剥夺睡眠脑电图、24小时动态脑电图以及持续数小时至数天的长时间视频脑电图。长期脑电图检查的主要适应证包括：癫痫的综合征分类；疑似癫痫时寻找发作间期放电或用于治疗评估；阵发性临床事件的阳性诊断；以及耐药性癫痫的术前评估。当标准脑电图检查结果为阴性时，可采用剥夺睡眠脑电图和动态脑电图来检测发作间期放电，以验证癫痫的综合征分类。这些检查有助于评估治疗效果，尤其是在临床评估困难时。长时间视频脑电图适用于耐药性癫痫，用于在术前评估背景下分析电-临床相关性，以及在阵发性临床事件频繁发生时完善阳性诊断。
