目的探讨发作期及发作间期脑电图对癫痫诊断的意义。方法对５６例癫痫患者常规脑电图（ＲＥＥＧ）与２４ｈ脑电图（ＡＥＥＧ）进行比较研究。结果①ＲＥＥＧ的阳性率为３０％，而ＡＥＥＧ的阳性率为８６％；②不同类型癫痫在发作期和发作间期大脑活动的规律和特点，ＲＥＥＧ无１例记录到癫痫发作，而ＡＥＥＧ有２７例（４８％）记录到癫痫发作全过程的大脑电活动变化。结论发作期的ＥＥＧ对确定癫痫类型有重要意义，全身性癫痫在发作的同时发作波在两侧半球同时出现，而部分性发作患者在临床发作的同时ＥＥＧ常局限在某一脑叶有单个棘波发放，此棘波处是癫痫的病灶的部位，这种局限棘波可扩散至全脑而临床出现全身阵挛发作，此类患者为部分性癫痫并非全身性癫痫。
Objective To investigate the significance of epilepsy in seizure and interictal EEG. Methods Fifty-six patients with epilepsy were studied by routine electroencephalogram (EEG) and 24-hour electroencephalogram (AEEG). Results ① The positive rate of REEG was 30%, while the positive rate of AEEG was 86%. ② The regularity and characteristics of brain activity in different types of epilepsy during the attack and interictal periods. None of the REEGs recorded epileptic seizures. AEEG had 27 cases (48%) recorded changes in brain electrical activity during the whole process of seizure. Conclusions The onset of EEG is of great importance in determining the type of epilepsy. Systemic epilepsy occurs simultaneously with seizures in both hemispheres, whereas in patients with partial seizures, the clinical manifestations of EEG are often limited to having a single spine Wave distribution, this spike is the site of epilepsy lesions, this spike can spread to the whole brain and clinical onset of generalized clonic seizures, such patients are not part of the generalized epilepsy epilepsy.
