Types of Strokes
About 87 percent of all strokes are ischemic strokes. These 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 account for only 13 percent of all strokes, but are much more serious. In these cases, an artery in the brain leaks or bursts, causing bleeding in the brain or near its surface.
Do not disregard stroke symptoms that quickly disappear. They could be the sign of a transient ischemic attack, also known as a TIA or 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 of a stroke, so it's important to recognize symptoms and act quickly. Quick response may mean the difference between short-term and permanent disability, as well as less chance of brain damage and greater chance of full recovery.
