If the symptoms last longer than that, it is important to get medical attention. If you experience any of these symptoms, call 911 immediately and consult with a qualified physician.

When the brain does not receive enough blood to repair itself, it cannot function properly. If the blood is not flowing properly, small collateral arteries may not be able to deliver the blood needed to repair the damage. Therefore, the brain suffers from a stroke. However, even if the blood flow to the affected area is normal, the blood flow can be reduced to a point that the brain cannot function properly.

Some of the risk factors for CVA stroke include smoking, high blood cholesterol, and high blood pressure. Smoking contributes to plaque buildup in the arteries and causes an increased risk of a stroke. This buildup of plaque in the arteries reduces blood flow to the brain. The brain is severely damaged when the blood supply is cut off. Inactive lifestyles and certain medical conditions may also increase the risk of a stroke. People over 65 years old are at greatest risk for stroke.
