Experts from the South American University of South Carolina have warned that middle-aged heavy migraines are a major warning sign for the risk of stroke.
One study found that people over 50 years of age with migraine, a common type of vision, had a risk of stroke over the next 20 years. Researchers found that those with migraine at a younger age did not have an increased risk of stroke.
Experts followed the case of 11,600 people for two decades and found that patients with aura after 50 years of age had a chance of having a stroke of 8.3%, 2.17 times more likely than those who did not migrate. Patients who had migraine without aura had no increased risk, regardless of the onset of the disease.
Study leader Xiao Michele Androklis, Head of Neurology at WJB Dorn VA, said
»South Carolina Medicine: I think this is very useful because many people who have a long history of migraine are concerned about the risk of stroke, especially when they grow up and when they have the risk of other cardiovascular diseases.
As far as we know, this is the first major prospective study to assess the relationship between years of migraine exposure and ischemic stroke.
