What is a Stroke?
A stroke happens when blood flow to a part of the brain stops. Because the brain needs oxygen, this can cause brain cells to die. As a result, a stroke is a medical emergency. Early treatment can help save lives and reduce long-term problems. According to the CDC, stroke is a leading cause of death and disability worldwide. Knowing about stroke can help you act quickly if you or someone you know is at risk.
