Cerebrovascular reactivity in subjects with migraine: Age paradox?

Migraine, and especially migraine with aura, is a recognized risk factor for stroke [1]; however, the mechanisms underlying the association between migraine and stroke are unclear. Notably, previous studies found that the contribution of migraine to the risk of stroke is more significant in younger women compared with the older ones [2,3] and in women with active migraine compared with those with past history of migraine [4], suggesting the presence of a migraine-specific factor increasing the risk of stroke.
