Sen S, Androulakis XM, Rosamond W, et al. Recent reports have highlighted the fact that 90 of strokes are preventable, which reflects an opportunity to decrease stroke related mortality and morbidity. Etiology of the observed association is currently being evaluated in this population,” they concluded. The World Health Organization lists stroke as the second leading cause of death and the third leading cause of serious long-lasting disability. Further, we report a stronger and significant association with the cardioembolic stroke subtype, with a significant but smaller association with thrombotic strokes. “Results from this prospective cohort are consistent with previous studies demonstrating an association between MA and ischemic stroke. No association was observed between migraine with aura and lacunar stroke. The benefit was most pronounced in migraine with frequent aura. Overall, those participants who experienced migraine with aura were 2.4 times more likely to experience ischemic stroke, 3 times more likely to have a stroke caused by a mass or clot in the heart (cardioembolic), and 2 times as likely to have a stroke caused by a clog in the brain (thrombotic) than patients who had migraine without aura. In a patient-level pooled analysis of patients with migraines both with and without aura, patent foramen ovale (PFO) closure was shown to be safe and reduced the average number of monthly migraine days and attacks compared with medical therapy. Strokes were classified as either thrombotic brain infarction, lacunar infarction, or cardioembolic stroke. Stroke diagnoses were based on medical record reviews. Participants were given an in-person questionnaire to determine the presence of migraine, either with or without aura, or non-migraine headaches. To further explore this relationship, researchers examined data from the Atherosclerosis Risk in Communities study, an ongoing prospective cohort study of 12,844 participants. Previous research has shown that migraine with aura is an independent risk factor for ischemic stroke, but its relationship with specific stroke subtypes is less well documented.Ĭould Epilepsy Drugs Treat Ischemic Stroke?Ĭerebral Venous Sinus Thrombosis Presenting as Hemorrhagic Stroke And finally, it puts these risks into a meaningful context with a risk/benefit assessment.Īura hormonal contraceptive migraine stroke risk.Migraines with aura are associated with increased risk of stroke, particularly cardioembolic stroke, according to recent research. However, this contraindication is based on data from the 1960s and 1970s, when oral contraceptives contained much higher doses of estrogen. It also examines how stroke risk is altered by the estrogen content of the CHC, by contributing factors such as smoking, age and hypertension, and by aura frequency. Combined hormonal contraceptives are contraindicated in women who have migraine with aura, in whom these drugs can increase the risk of ischemic stroke. This article clarifies the stroke risk of CHCs and examines their impact on migraine. Yet studies consistently show that stroke risk is not increased with today's very low dose CHCs containing 20-25 µg ethinyl estradiol (EE), and continuous ultra low-dose formulations (10-15 µg EE) may even reduce aura frequency, thereby potentially decreasing stroke risk. People who experience aura might have increased tendency to form blood clots due to temporarily narrowed blood vessels, which can predispose them to stroke, Tietjen said, which studies suggest may increase stroke risk. Their use, however, is still restricted by current guidelines due to concerns of increased stroke risk - concerns that originated over half a century ago in the era of high dose contraceptives. Migraine with Aura is a risk factor for stroke, particularly for women, even those younger than 45 or even 35, Tietjen said. Clearing this confusion is a key issue for headache specialists, since most women with migraine have menstrual-related migraine (MRM), and some CHCs can prevent this particularly severe migraine. Unnecessary confusion still surrounds the use of combined hormonal contraceptives (CHCs) in the setting of migraine with aura (MwA).
