摘　　要：目的：探讨发作性头痛者２４ ｈ 动态脑电图（ＡＥＥＧ） 监测的价值。方法：对１２０ 例发作性头痛患者进行２４ ｈ ＡＥＥＧ 监测，分析发作期和间期脑电活动特点，并与常规ＥＥＧ 作自身对照。结果：ＡＥＥＧ 非特异性异常５４ 例（４５ ％ ） ，捕捉到癎样放电１１ 例（９－２ ％ ） ，ＥＥＧ 非特异性异常３１ 例（２５－８ ％ ） ，捕捉到癎样放电仅４ 例（３－３ ％ ） ，ＡＥＥＧ 异常率（５４－２ ％ ） 明显高于ＥＥＧ（２９－２ ％ ） 。ＡＥＥＧ 癎样放电多见于觉醒期和发作期。结论：发作性头痛患者确有一小部分属于头痛型癫癎，２４ ｈ 脑电监测对其鉴别诊断有重要意义。Objectives:To study the value of 24 hour AEEG in patients with paroxysmal headache.Methods:Twenty four hour AEEG monitoring was performed on 120 patients with paroxysmal headache. The ictal and interictal EEG features were analysed and compared with the routine EEG of the same patients. Results: AEEG showed nonspecific abnormatity in 54 ones(45%) and epileptiform discharges in 11 patients (9.2%). Rountine EEG only showed nonspecific abnoramatity in 31 ones(25.8%) and epileptiform discharges in 4 patients(3.3%). The abnormality rate of AEEG(54.2%) was higher than that of routine EEG(29.2%). The epileptiform discharges were mostly seen during seizures and wakefulness.Conclusions: A small portion of the patients with paroxysmal headache might really belong to epilepsy, 24 hour hour AEEG might be of important significance in the differential diagnosis of paroxysmal headache.
