Abstract

We studied 14 patients with migraine with aura (group 1) and 16 patients with migraine without aura (group 2), 92.8% had EEG alterations in ictal and 57% in the interictal phase in group 1. 37.5% had EEG alterations in ictal and 18.7% in the interictal phase in group 2. There was a statistical difference between the two groups and between both phases. We think that patients with EEG alterations during both phase, may have a lower ischemic threshold.

摘要

我们研究了14例伴有先兆的偏头痛患者（第1组）和16例无先兆的偏头痛患者（第2组），第1组中92.8%的患者在发作期脑电图有改变，57%在发作间期有改变。第2组中37.5%的患者在发作期脑电图有改变，18.7%在发作间期有改变。两组之间以及两个阶段之间均存在统计学差异。我们认为在两个阶段脑电图均有改变的患者，其缺血阈值可能较低。
