Migraine With Aura Raises Stroke Risk 73% in Middle-Aged and Older Adults

Migraine affects over a billion people worldwide, but its link to serious cardiovascular events like stroke is often underappreciated. A new study published in Neurology Open Access adds important evidence that migraine — particularly the type accompanied by visual disturbances called aura — significantly raises the risk of ischemic stroke in middle-aged and older adults.

Researchers analyzed data from 11,381 participants in the REGARDS cohort, all aged 45 or older. Over a mean follow-up of 6.4 years, those with migraine with aura had a 73% higher risk of ischemic stroke compared to people without migraine. Migraine without aura showed no statistically significant increase in stroke risk, suggesting the aura phenomenon itself may play a mechanistic role in cerebrovascular vulnerability.

One of the most striking and unexpected findings was the elevated risk seen in men under age 72. In this group, any migraine — with or without aura — more than tripled ischemic stroke risk (HR 3.67). This runs counter to prior research showing young women bear a disproportionate stroke burden from migraines, possibly due to hormonal factors or oral contraceptive use.

The study adjusted for major confounders including hypertension, diabetes, smoking, atrial fibrillation, dyslipidemia, and BMI, strengthening its credibility. Still, migraine history was self-reported and visual changes were used as a proxy for aura, which may introduce some misclassification. The cohort was also older on average, limiting generalizability to younger populations.

For health-conscious adults, these findings reinforce the importance of treating migraine with aura as more than just a pain condition — it is a potential cardiovascular risk signal. People with aura migraines, especially middle-aged men, should discuss stroke prevention strategies with their physicians, including aggressive management of modifiable risk factors like blood pressure, cholesterol, and smoking.
