Migraines and strokes linked in major study
18th November 2009

Strokes have been linked to another condition which affects millions of people across the globe.

After looking through 21 studies and 622,381 individual cases, researchers at Johns Hopkins University School of Medicine and its Heart and Vascular Institute found that migraine headaches are associated with a doubled chance of the most common kind of stroke.

Strokes where blood supply to the brain is suddenly cut off by the build-up of plaque or a blood clot is 2.3 times more likely with those experiencing migraines, with women slightly more at risk.

Assistant professor at Johns Hopkins Saman Nazarian, who authored the report, said the largest study of its kind on the topic reinforces the links between migraine and stroke.

The expert continued: "Identifying people at highest risk is crucial to preventing disabling strokes. Based on this data, physicians should consider addressing stroke risk factors in patients with a history or signs of light flashes and blurry vision associated with severe headaches."

According to the NHS, migraines are common and affect around one in four women and one in 12 men in the UK.
