Blood Type May Influence Stroke Risk

Following a review of health histories of nearly 17,000 people, researchers report that individuals with type A blood are 16% more likely suffer a stroke before age 60 than those with other blood types. On the other hand, the risk is lowest for those with type O blood. The researchers explain that type O blood contains fewer proteins that are known to contribute to clot formation, which is necessary for a stroke to occur. Neurology, August 2022
