Brain Research: Stroke
Do you know much about stroke? Do you know anyone that has had a stroke? A stroke occurs when the arteries carry blood to the brain gets a clot which stops oxygen from getting to it. If there no blood getting to the brain, a person could lose the function to breath and maintain a heart beat (edmonds). stroke symptoms can come on suddenly and very depend on the stroke. strokes mostly occur in people over the age of 60, but they can happen to younger people. the brain has four main arteries that bring blood up from the heart.
Strokes can come on suddenly and symptoms can very depending on how bad the stroke is. In the book The Human Brain the main idea is there are different kinds of stroke. An ischemic stroke is a result of a blockage of an artier. A hemorrhagic stroke is "bleeding from a blood vessel into the brain" (221).
In the article " Strokes Overview" from How Stuff Works, the author describe facts about strokes, risk factors, symptoms, and treatment for stroke. The author explains that " diabetic face three times the risk for stroke " (Edmonds). She also that stroke are the " third leading cause of death in the United States" (Edmonds).
In the book Blood for the Brain, the author explains that two arteries , the caroid carries the blood mainly to the front part of the brain, and the vertebral artier bring blood to the rear of the brain(parker,10) there are reasons why the blood supply to your brain could fail and cause a stroke"such as narrowing and harness of the artier,or a blood clot swept along from else where in the body " (parker,11).
The New York Times article called "Mini Strokes can Be Treated to Prevent Big One" , explains a story about a woman who had a mini stroke. She had a "T.I.A- a transient ischemic attack, commonly called a mini-stroke, in which the blood supply to part of the brain is cut off for a breif period of time, in Helen's case her friends estimated , for about 20 minutes"(Brody). the author introduces that "most attacks occur in people over the age of 60 " (Brody).
In conclusion , strokes are serious because they can impair your motor skills and cause death.

5 to know before you go
- Four arteries are close to each other
- If the stroke breaks up quickly than you will not loses your motor skills
- Anticoagulants help break up the clot
- 700,000 strokes occur each year just in the Unites States
- 40% of people who have a stroke will experience moderate to sever impediments
