Stroke

Frequently Asked Questions

1. What is stroke?

A stroke is serious, just like a heart attack. A stroke is sometimes called a "brain attack." Most often, stroke occurs when blood flow to the brain stops because it is blocked by a clot. When this happens, the brain cells in the immediate area begin to die.

Some brain cells die because they stop getting the oxygen and nutrients they need to function. Other brain cells die because they are damaged by sudden bleeding into or around the brain.

The brain cells that don't die immediately remain at risk for death. These cells can linger in a compromised or weakened state for several hours. With timely treatment these cells can be saved. Knowing stroke symptoms, calling 911 immediately, and getting to a hospital as quickly as possible are critical.
