Men with divorced parents are three times more likely to have a stroke than men whose parents are married, according to a study from the University of Toronto. The study, which will be published in the International Journal of Stroke, found that men who experienced a parental divorce before they turned 18 were at higher risk. Women from divorced families did not have a higher risk. The stress of this type of life event may carry forward into later life. Elevated risk does not mean everyone with this type of family history is doomed to have a stroke.
