Epileptic seizures and EEG interictal paroxysmal activity (PA) usually occur in an apparently unpredictable fashion, and a small number of patients with truly epileptic seizures may not present any PA on repeated EEGs. With the aim of increasing the possibility of recording interictal or ictal PA, several activation procedures are routinely carried out. In rarer instances, seizures seem to be more or less specifically evoked by unusual triggering procedures, or are chronologically related to biological rhythms. These different activating procedures may have different effectiveness depending on the type of epileptic syndrome. In the present paper the Authors describe the different activating procedures, both routinely employed and unusual ones. Their possible differential use with regard to the different epileptic syndromes and to the specific epileptologic history of the patient are examined. A selective use of these procedures is suggested, as an accurate choice of such techniques may increase the diagnostic usefulness of the EEG, in particular in patients whose basal recording is not contributory.
癫痫发作和脑电图发作间期阵发性活动（PA）通常以明显不可预测的方式出现，少数真正患有癫痫发作的患者在多次脑电图检查中可能未出现任何PA。为了增加记录发作间期或发作期PA的可能性，通常会进行几种激活程序。在罕见的情况下，癫痫发作似乎或多或少是由不寻常的触发程序特异性诱发的，或者在时间上与生物节律相关。根据癫痫综合征的类型，这些不同的激活程序可能具有不同的效果。在本文中，作者描述了常规使用的和不寻常的不同激活程序。研究了它们在不同癫痫综合征和患者特定癫痫病史方面可能的差异使用。建议选择性地使用这些程序，因为准确选择此类技术可能会提高脑电图的诊断效用，特别是对于基础记录无诊断价值的患者。
