There are many risk factors associated with stroke. The more risk factors a person has, the greater the chance that he or she will have a stroke. Some of these you have no control of, such as increasing age, family health history, race and gender. But you can change or treat most other risk factors to lower your risk. The chance of having a stroke more than doubles every decade after the age of 55. The chance is greater in people who have a family history of stroke. African Americans have a much higher risk of disability and death from a stroke than whites, in part because blacks have a greater incidence of high blood pressure, a major stroke risk factor. Overall, the incidence of stroke is about equal for men and women. However, at all …show more content…
Hemorrhagic stroke accounts for about 17 percent of stroke cases. It results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.

Ischemic stroke accounts for about 83 percent of all cases. It results from an obstruction, typically a blood clot. These clots are called a cerebral thrombus (a blood clot that develops in the clogged part of the vessel) or a cerebral embolism (a blood clot that forms at another location in the circulatory system then breaks loose, enters the bloodstream and travels through the brain's blood vessels until it reaches vessels too small to let it pass).

CVA (Cerebrovascular Accident), commonly known as a stroke, is a cardiovascular disease affecting the blood vessels that supply blood to the brain. A stroke occurs when a blood vessel that brings oxygen and nutrients to the brain bursts (hemorrhagic) or is clogged by a blood clot or some other mass (ischemic). When a vessel bursts or is clogged it deprives the brain of blood and oxygen it needs. If the brain does not receive the nutrients supplied by the blood after several minutes the cells and tissue begin to die, causing irreversible damage.
