Stroke
Cerebrovascular accidents also known as strokes, occurs when blood supply of an artery stop getting to the brain. It is one of the leading causes of death throughout the world. There are many factors that can lead to stroke, but there are also ways to treat it or even help prevent it. No matter how healthy people are or because of genetics it can still occur in anyone. Knowing more about diseases that occur more frequently can help save lives in this world.
Strokes can be caused for many different reasons, but the most common cause is a blockage in the artery in the brain by a clot (thrombosis). The part of the brain that is suppose to receive the blood from the clotted artery won’t get anymore blood nor oxygen. Not having a blood supply to the brain result in cells in that section to die. A clot could of formed due to risks of high blood pressure (hypertension), high cholesterol, diabetes, and smoking. There are other types of strokes such as: embolic stroke, cerebral hemorrhage, subarachnoid hemorrhage, vasculitis, and migraine headaches. Several strokes are usually cause by some kind of problem with blood getting to the brain. Blood vessels can have a clot, rupture and bleed, leak, be inflamed, or even narrowed to a small size where not enough blood is getting to the place its suppose to. (MedicineNet)
The risk of having a stroke is different in everyone. The risk factors of people getting a stroke that cannot be changed is your age, heredity, sex, and prior stroke, TIA or heart attack. Many people that are aging in their mid sixties have a very high risk of getting a stroke. If you are African American, the risk of you having a stroke is higher than a Caucasian because blacks have higher risks of high blood pressure, diabetes and obesity. If anyone in your family history had a stroke it also puts you at a higher chance. Males are more common in having a stroke than women, but more women have died by strokes because the use of birth control pills and pregnancy pose special stroke risks for women. Previously having a stroke before can put someone at a risk of having another stroke. These people prior to strokes and heart attacks need to be aware that the chance of getting another stroke or heart attack is at a higher rate than before. Adding to these risk factors, there are more ways that increase your risk of strokes. Having a poor diet can cause someone to have high blood pressure, high cholesterol, diabetes, heart disease, and lead to obesity. People can change their lives by eating nutritiously, physically being active everyday to help reduce the chance of stroke, and not smoking. Also, a diet containing five or more servings of fruits and vegetables per day may reduce the risk of stroke too. (AmericanHeartAssociation)
