[摘要] 目的：探讨动态脑电图（AEEG）对癫痫的诊断价值。方法：对96例癫痫患者和78例非癫痫发作性疾病患者进行常规脑电图（REEG）和AEEG进行对比研究。结果：癫痫组REEG和AEEG的总异常率差异有统计学意义（P＜0.01）；癫痫组与非癫痫组AEEG的总异常率差异有统计学意义（P＜0.01）；清醒期共出现痫样放电29例（72.5%），睡眠期共出现38例（95.0%），二者比较差异有统计学意义（P＜0.01），睡眠期痫样放电多于清醒期。结论：AEEG对癫痫的诊断和鉴别诊断有重要意义。

[Abstract] Objective: To explore the diagnostic value of AEEG to epilepsy. Methods: The contrast study of routine electroencephalography (REEG) and ambulatory electroencephalography (AEEG) of 96 patients with epilepsy and 78 patients with non-epileptic attack disorder were conducted. Results: The total abnormal rate of REEG and AEEG in group epilepsy had statistical difference (P＜0.01). The total abnormal rate of AEEG between epilepsy andnon-epileptic attack disorder had statistical difference (P＜0.01). 29 cases (72.5%) occurred epileptic discharge in awake period and there were 38 cases in sleep period (95.0%), it had significant difference (P 动态脑电图是目前癫痫的辅助诊断及治疗评价最为有效的手段。动态脑电图对某些神经性症状的鉴别诊断尤为重要，如晕厥、发作性头痛、头昏，可用以鉴别其病源。对于心理原因引起的病症，动态脑电图可确认其心理因素与疾病发作的联系，以明确诊断。临床上动态脑电图可用于脑死亡的判断，此对脏器的移植具有重要意义，还可对颅脑外伤和昏迷及呼吸暂停综合征患者的动态监测，协助判断预后[6-7]。本组资料显示，非癫痫发作性疾病患者AEEG的总异常率为20.5%，且发作间期于睡眠中易出现脑电活动异常，无论临床表现还是脑电变化都提示癫痫有夜间发作倾向。说明虽然癫痫是一种反复性、发作性疾病，但并非在发作性的症状都是癫痫，AEEG可用于癫痫的鉴别诊断。
