ResumoThe association between migraine and epilepsy is intriguing and perplexing, and its nature remains to be determined. Epilepsy may present as a complication of migraine, but the alliance between epilepsy and migraine is far wider in scope. The subject has been reviewed extensively and explored in great depth in book form.1 The relationship is explored in this article in terms of the general concept that migraine is a primary brain response evoked either by variant physiology or by structural change. There are three major issues regarding epilepsy and migraine: Does epilepsy occur in the course of the migraine attack, that is, in the form of true migraine-induced epilepsy (migralepsy)? Does migraine cause epilepsy because of predisposing epileptogenicity of the brain? Can epilepsy present as a migraine syndrome? This article defines the conditions under which each of these circumstances may be operative in migraine subjects and gives clinical examples. A genuine association between migraine and epilepsy has been obscured by uncertainty in the definitions of the disorders. Now, separate classifications of epilepsy and headache exist that were developed and refined in this decade,8, 12 so there is less variability to the recent epidemiologic reporting. The authors believe that, in addition to the epidemiologic value of classifying the specific relationships between the two disorders, such classification is important for differential diagnosis and may provide insight into the cause of migraine. Accordingly, the authors propose a classification of migraine-related epilepsy, which is outlined and justified in the following text.
