A stroke occurs when a blood vessel in the brain is blocked, leaks, or bursts.
A stroke occurs when a blood vessel in the brain is blocked, leaks or bursts. Without blood and the oxygen it carries, part of the brain begins to die. The part of the body controlled by the damaged area of the brain can't function properly. An ischemic stroke occurs when a blood vessel is blocked by a blood clot in the brain. With a hemorrhagic stroke, there is bleeding into the brain tissue.
What is the major risk factor for stroke?
The risk of stroke varies directly with the blood pressure. As blood pressure rises, so does the risk of stroke. The role of hypertension as a risk factor for stroke is further magnified by how common it is. Close to one in three adults in America has hypertension.
Strokes rarely occur in people under 65.
A stroke can happen to anyone. However, the older you are, the higher your risk. Still, nearly one-quarter of strokes occur in people under the age of 65. The chance of having a stroke approximately doubles for each decade of life after age 55.
Who is more likely to die from a stroke?
Because women live longer than men, more women than men die of stroke each year. Women tend to have strokes when they're older and are more likely to die. Men are more likely to have strokes at younger ages, so their survival rate is higher.

A stroke is not necessarily an emergency.
A stroke is an absolute emergency. Immediate medical attention is necessary for symptoms that appear to be a stroke, even if the symptoms disappear quickly.
Note: Patients who arrive at the emergency room within three hours of their first symptoms tend to be healthier three months after stroke than those who delayed care.
