Seizures and Migraines Linked by Single Gene Mutation

Seizures and migraines may in fact be linked as they could be produced by a single gene mutation, says a recent study. The two brain events have always been considered separate physiological phenomena in the brain, as seizures are marked by electrical hyperactivity, while migraine auras, based on an underlying process called spreading depression, are marked by a silencing of electrical activity in part of the brain. Also, seizures spread rapidly, but migraines propagate ...
