"5.5 million people in the United States have survived a stroke but live with its impact every day."
is a stroke?
Stroke is a disease that affects 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 or is clogged by a blood clot or some other mass. Because of this rupture or blockage, part of the brain doesn't get the blood and oxygen it needs. Deprived of oxygen, nerve cells in the affected area of the brain can't work and die within minutes. And when nerve cells can't work, the part of the body they control can't work either. The devastating effects of a severe stroke are often permanent because dead brain cells aren't replaced.
There are two main types of stroke. One (ischemic stroke) is caused by blockage of a blood vessel; the other (hemorrhagic stroke) is caused by bleeding. Bleeding strokes have a much higher fatality rate than strokes caused by clots.
What are the effects of a stroke?
People can be affected in quite different ways. This partly depends on which area of the brain is damaged, because different parts control different abilities such as speaking, memory, swallowing and moving. The most common signs of a stroke are weakness, paralysis or numbness of the arm and leg. Sometimes the people who have had stroke may be difficult to speak or understand.
What are the risk factors?
Age over than 40 should have an annual blood pressure check to maintain the high blood pressure.
Smokers have double the risk of stroke as non-smokers.
The people who have Diabetes.
Too much alcohol increases the risk of a stroke.
The most common type of stroke is a blockage. This is called an ischaemic stroke, which happens when a clot blocks an artery that carries blood to the brain.
A stroke is a brain attack A stroke is what happens when the blood supply to part of the brain is cut off.
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.
A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack."
A stroke is sometimes called a "brain attack." A stroke can injure the brain like a heart attack can injure the heart. A stroke occurs when part of the brain doesn't get the blood it needs.
