October 29 is World Stroke Day. All around the world, the goal of this event is to raise awareness of stroke symptoms and emphasize the critical importance of calling 911 immediately when these symptoms are recognized.

What is a stroke?

A stroke is a medical emergency that occurs when blood flow to part of the brain is interrupted or reduced, preventing brain tissue from getting the oxygen and nutrients it needs. Brain cells begin to die within minutes, so immediate treatment is critical.
