Stroke is a type of cardiovascular disease. It affects the arteries leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it starts to die.
What Are the Types of Stroke?
Stroke can be caused either by a clot obstructing the flow of blood to the brain (ischemic strokes) or by a blood vessel rupturing and preventing blood flow to the brain (Hemorrhagic or bleeding strokes).
Diagnosis of Stroke
When someone has shown symptoms of a stroke or a TIA (transient ischemic attack), a doctor will gather information and make a diagnosis. A doctor may use many different tests. The ones listed here are just some of the more common options.
Impact of stroke
Stroke is the No. 3 cause of death in the United States, behind diseases of the heart and cancer.
