Injury to Your Brain

Also called a "brain attack," a stroke is an injury to your brain.

Hemorrhagic vs. Ischemic Stroke

Blood Supply to Part of Brain Interrupted

A stroke happens when the blood supply to a part of your brain is interrupted. Insufficient blood supply prevents your brain from receiving the oxygen and nutrients it needs to stay healthy.

Causes Sudden Loss of Function

Within minutes, your brain tissue begins to die, causing a sudden loss of function. A stroke is a medical emergency and requires quick treatment. With proper treatment, damage to your brain can be minimized, but treatment must begin quickly.
