In the United States stroke has been reported as the third leading cause of death. There are approximately 795,000 cases of strokes that are reported each year in the United States. Over 143,579 of these people die each year from having a stroke. Strokes can be very serious and result in death if not treated immediately. There are several types of strokes that one may have and different injuries that may occur depending on what type of stroke someone has (Center for Disease Control and Prevention, 2007). There are also different risk factors associated with a stroke. Some of these risk factors can be controlled while some risk factors are hereditary (American Stroke Association, 2009). A stroke can occur in different ways. One way is by having parts of the brain blocked from the blood supply. When a blood vessel bursts within the brain it can also cause a stroke. Having blood supply blocked or a blood vessel burst causes damage to the brain. Stroke is the number one cause of disability that last for a long time and can occur at any age. There are three different types of strokes. Ischemic stroke is one type, it occurs when an artery is blocked that supplies blood and oxygen to the brain. The most common cause of an artery blockage is blood clots. Hemorrhagic stroke is another type of stroke, which occurs when an artery bursts in the brain. Hemorrhagic stroke can occur in several ways, such as; an aneurysm, which is a weak or thin area on an artery wall that can expand like a balloon. The thin walls of the artery can rupture or break. Hemorrhagic stroke can also occur when arterial walls lose their elasticity and become thin. Once an arterial wall becomes thin it can crack and bleed. Another risk of a hemorrhagic stroke is high blood pressure. Transient ischemic attacks is...
