Migraines double stroke risk

People who suffer from migraines are twice as likely to have a stroke as others, according to researchers. As the BBC http://www.bbc.co.uk reports, a review of 14 studies by scientists in the US, Canada and Spain found that migraines roughly doubled the stroke risk, and women with migraines who are also on the pill are eight times more at risk of a stroke that those who do not. The findings are published in the British Medical Journal http://www.bmj.org .
