Migraine and stroke: from a questioned relationship to a supported comorbidity

Abstract

Migraine and stroke are two common and prevalent diseases. The relationship between them is an ongoing, intriguing matter of debate. About 40 years ago, some different reports on this topic raised the question of the existence of a relationship between the two diseases. To date the existence of a comorbidity between migraine and ischaemic stroke is supported by population and clinical series studies. Literature data on this subject are reviewed in this report.
