脑电图在偏头痛患者中的诊断价值

目的:探讨脑电图在偏头痛患者中的诊断价值.方法:连续收集武汉大学人民医院和武汉大学中南医院2015年6月至2016年6月确诊的偏头痛患者80例(实验组),总结其脑电图特点,同时按照1∶2配对设计的原则,选取同期成人体检者160例作为对照组.结果:实验组中脑电图异常38例,对照组40例,均为轻度及以下异常.实验组中脑电图特点总结:38例异常脑电图中有21例为轻度异常脑电图,表现具有相对特异性,主要为局灶性尖波,即局部导联的散发性低波幅尖波、小尖波,未见明显的尖慢波、棘波、棘慢复合波,以临床上疼痛的部位相对多见(13/21,61.9％).结论:偏头痛患者脑电图改变具有相对特异性,其对偏头痛患者的诊断具有较好的参考价值.

Value of electroencephalogram in the diagnosis of migraine patients

Objective:To evaluate the diagnostic value of electroencephalogram (EEG) in acute exacerbation of migraine.Methods:Eighty cases of migraine patients in Renmin Hospital of Wuhan University and Zhongnan Hospital of Wuhan University from June 2015 to June 2016 were collected,the EEG characteristics were analyzed.Meanwhile,healthy subjects were selected as the control group according to 1:2 design methods.Results:There were 38 cases of abnormal EEG in the migraine group and 40 cases in the control group.EEG features of migraine patients:38 cases of abnormal EEG patients were mild abnormalities,the performance of the relative specificity,mainly for the local lead of the sporadic high amplitude spikes and slow complex wave.There were 13 patients (13/21,61.9％) who met the site of clinical pain.Conclusion:EEG in patients with acute exacerbations of migraine is relatively specific.EEG has a good reference value for the diagnosis of migraine patients.
