动态脑电图在鉴别儿童头痛型癫痫和偏头痛的作用

THE VALUE OF AEEG IN CHILDREN WITH HEADACHE EPILEPSY AND MIGRAINE

目的:探讨儿童的头痛是头痛型癫痫发作引起还是偏头痛发作所致。方法: 对82例经常有头痛发作的患儿做动态脑电图检查,至少记录到一次头痛发作时的实时脑 电图,并对头痛发作前、发作中和发作后的脑电图结果进行分析。结果:24例患儿的动 态脑电图结果正常;58例异常,其中非特异性异常56例,脑电图表现为头痛发作时或发 作间期出现阵发性θ活动、δ活动;特异性异常2例,脑电图表现为头痛发作时出现棘 波、尖波与尖慢波。结论:临床上难以诊断是头痛型癫痫发作还是偏头痛发作所引起的儿 童发作性头痛,动态脑电图有帮助确诊的作用。

Objective: To explore children headache is the result of headache epilepsy or migraine. Methods: 82children with headache seizures detected by AEEG, taked down EEG in headache seizures at least one time, AEEG was analyzed in preseizures, intraseizures, posts ezures of headache. Results: AEEG of 24 patients was in normal in 82 patients with headache seizures, 58 patients were abnormal: AEEG of 56 patients was abnormal, then showed mainly paroxysmal θand δ activity, AEEG of 2 patients was specific abnormal, they showed epileptiform discharges in headache seizures. Conclusion: AEEG was of action in the diagnosis and differential diagnosis between headache epilepsy and migraine in children.
