TUESDAY, May 1 (HealthDay News) -- Women who experience migraines while they're pregnant are significantly more likely to suffer a stroke, heart attack or other vascular problems, a new study suggests.

Although many questions remain, there are steps women can take to protect themselves, said the authors of the study, to be presented Tuesday at the American Academy of Neurology annual meeting, in Boston.

"Clearly this is not proving a cause and effect. It's an association that we find, and it has to be looked at in more studies," said study author Dr. Cheryl Bushnell, an assistant professor of medicine (neurology) at the Duke Center for Cerebrovascular Disease at Duke University Medical Center.

"But I think that we can assume that women who have migraines seem to also have vascular disease, and women who have migraines and vascular risk factors should be trying their best to modify or control those risk factors while they're pregnant. That's a common-sense approach," Bushnell added.

Dr. Richard Lipton, director of the Montefiore Headache Center and professor of neurology and epidemiology at Albert Einstein College of Medicine in New York City, said: "People with migraine should view migraine the same way they would view diabetes or high cholesterol, as a medical problem that should be managed to make life better today and prevent complications tomorrow. Rather than being alarmed, people with migraine should get the migraines treated and make sure they modify risk factors for heart disease and stroke by maintaining a normal body weight and treating high blood pressure."

Previous research by the study authors had shown that migraines were a risk factor for having a stroke during pregnancy. Migraines had also shown up as a predictor of heart disease during pregnancy.

Migraines have also been associated with stroke and heart disease in non-pregnant women.

"Migraine, particularly migraine with aura, is known to be a risk factor for heart disease and stroke, and there's lots of evidence for that," Lipton confirmed.
