World Stroke Day is Thursday, Oct 29. Stroke is the second leading cause of death worldwide. In the U.S., almost 800,000 people have a stroke annually.
A stroke can occur when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen. Within minutes, brain cells begin to die.

Though the risk for stroke rises with age, Dr. Miller says anyone at any age can suffer a stroke.
"If any of these symptoms happen, no matter how old you are, don't wait; call 911," says Dr. Miller. "Due to concerns around COVID-19, many people are skeptical to come to the hospital, but the faster we can diagnose and treat a stroke, the better the outcome."
