Migraine May Increase Risk of Stroke

A recent study found that adults who suffer from migraine headaches have twice the risks of ischemic stroke as compared to those who do not suffer from migraines. According to a Johns Hopkins press release, researchers from Johns Hopkins have affirmed that migraine sufferers are twice as likely to develop and experience the most common type of stroke. Ischemic stroke occurs when blood supply to the brain is suddenly cut of due to plaque buildup or a blood clot blocking a blood vessel in the brain.

The said project involved polling the results from 21 studies that involved 622,381 male and female participants, mostly from North America and Europe and aged between 18 and 70. None of the participants have suffered from stroke at the start of the study. The results showed that those who experience migraine symptoms such as seeing flashing lights, auras, zigzag lines and blurred side vision have more than twice the risk of ischemic stroke- 2.5 times for males and 2.9 times for women.

There is a once popular theory that migraines are caused by the rapid changes going through blood vessels in the brain. This might have explained the relationship between migraines and the risk of ischemic stroke. But that theory has since been proven incorrect. Although the risk is there, researchers still need to further study what the real relationship between migraine and stroke is.
