Strokes are scary, seemingly leaping out of nowhere. They are the third leading cause of death in the United States and for those who survive, they are the leading cause of disability in adults. But strokes don’t have to be mysterious. In fact, research shows 90 percent of strokes are caused by dietary and lifestyle factors, which means you can lower your risk with a few changes to how you live.
A stoke occurs when an artery that carries blood to the brain either becomes blocked or ruptures. This starves the brain of blood and oxygen, often causing permanent brain damage. A stroke can leave someone with impaired speech, memory, or movement. How this damage affects the person depends on which parts of the brain were damaged and to what degree.
