Migraine Sufferers at Increased Risk for Stroke

An association between migraine and ischemic stroke has been noted in several observational studies, particularly among patients who experience migraines with an aura. But whether an association exists between migraine and hemorrhagic stroke is less clear. To evaluate the relationship between migraine and hemorrhagic stroke (either intracerebral or subarachnoid hemorrhage), researchers in Italy conducted a meta-analysis of eight studies involving a total of 1,600 hemorrhagic strokes: four case-control trials and four with a cohort design.
