Strokes don’t occur often in young adults, but having Type A blood increases your risk of having a debilitating early onset stroke 16% while having type O blood reduces that risk by 12%.  Epidemiologists at the University of Maryland’s School of Medicine draw these conclusions from their meta-analysis of 16,927 stroke victims who participated in 48 different multi-national studies. 
The control group consisted of nearly 600,000 persons without a stroke history.

These blood group associations were stronger in younger patients. The analysis also demonstrated an association of the same blood groups with early venous thromboembolism, a key driver of early stroke.
