Stroke is a Cardiovascular Accident (CVA) or disease that affects the flow of blood to the brain. A stroke occurs when part of the brain is deprived of oxygen due to a blocked (blood clot) or ruptured blood vessel. When part of the brain is deprived of oxygen, nerve cells within the affected area are unable to function and they die within minutes. This will also affect parts of the body controlled by the oxygen- deprived brain cells.
