Overview

Most of us are so busy going about our lives, we don't often think of how our brain actually works as the master control of all we do. It's true. At any given moment, our brains are carefully—often seamlessly—coordinating our every move, thought and emotion. But like any organ in the body, the brain needs a steady supply of oxygen- and nutrient-rich blood.

Stroke happens when a blood vessel in the brain is suddenly blocked or bursts. It's a leading cause of death and disability among adults. In fact, someone has a stroke every 40 seconds in the U.S.

Experts say the good news is that most strokes—4 out of 5—could be prevented. Survival is also much more likely these days thanks to advances in medical care and access to more timely treatment.
