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.
