What is the risk of stroke associated with migraine with aura in women?
The risk of stroke associated with migraine with aura in women is higher than in men. The most recently published meta-analysis reported an increase in ischemic stroke in patients with migraine with aura, with an odds ratio of 2.51. Furthermore, the risk increases even more in women with migraine with aura who use oral contraceptives (OR, 7.02; 95% CI, 1.51 32.68) and in cigarette smokers (OR, 9.03; 95% CI, 3.11–27.11). Despite this, the absolute risk of migraine-associated stroke is relatively low.
