Can Migraine Increase Your Risk of Stroke?

According to a study in a recent online issue of Neurology, new research suggests older people who experience migraines may have an increased risk of stroke, but only if they are smokers. For the study, 1,292 people from the Northern Manhattan Study with an average age of 68 who reported migraine were followed for an average of 11 years to see who developed heart attacks or stroke. Of those, 187 had migraine without aura and 75 had migraine with aura. During the study, a total of 294 strokes, heart attacks and deaths occurred. The study did not find an association between migraine with or without aura and the risk of either stroke or heart attacks. However, among smokers, migraine was associated with a three-fold increased risk of stroke, whereas among smokers, migraine was not associated with a stroke risk. “Our findings may provide more evidence as to why quitting smoking is important for people who experience migraine,” said the study author. “While this investigation of migraine and vascular events in older people found that only smokers with migraine have an increased risk of stroke, earlier studies have shown that women younger than 45 who have migraine with aura are also at an increased risk of stroke, whether or not they smoke.” To learn more about this study, click here.
