Types of Strokes

About 87 percent of all strokes are ischemic strokes, strokes that occur when a blood vessel to the brain is suddenly blocked. Without the oxygen carried by blood, the brain will die, resulting in the body's inability to work properly. Hemorrhagic strokes, which account for 13 percent of all strokes, occur when an artery in the brain leaks or bursts causing bleeding in the brain or near its surface. Although hemorrhagic strokes are less common than ischemic strokes, they are much more serious.

Do not disregard stroke symptoms that quickly disappear. They could be the sign of a transient ischemic attack, also known as a mini stroke. TIAs serve as a warning sign that a real stroke is imminent, but early treatment for TIAs can help prevent full-blown strokes.

Brain damage can start within minutes after a stroke, so it is important to recognize stroke symptoms and act quickly. Quick response to a stroke may mean the difference between short-term or permanent disability, as well as less chance of brain damage and greater chances for a full recovery.
