SANTIAGO DE COMPOSTELA - People who have migraines are twice as likely to suffer a stroke than those who do not experience the throbbing headaches, researchers said.

Women who experience migraines and who are also on the pill are up to eight times more at risk of a stroke than those not taking the oral contraceptive, according to a review of studies by scientists in the US, Canada and Spain.

The findings, published in the journal BMJ Online First, also suggest that those who suffer interrupted vision with their migraine are at slightly higher risk than those who do not - 2.27 times as likely to have a stroke against 1.86 times.

The extra threat to health may be caused by the reduced blood flow which usually occurs in a migraine, the researchers suggest. They include specialists from the University of Santiago de Compostela in Spain, Washington University, Washington DC, and the Royal Victoria Hospital, Montreal.

About a quarter of women in their mid to late 30s suffer migraines. The new research suggests that the increased risk of stroke for women who suffer migraines and take the pill is far higher than was previously thought. But the team says more work is needed since only three of the 14 migraine and stroke studies they looked at included the added threat from contraceptives.

"Given that use of oral contraceptives is prevalent among young women, the potential risk of stroke among women with migraine who are also users of oral contraceptives must be further investigated," they said.
