As soon the stroke starts, the brain cells die shortly. However, if the blood supply is not cut off, some of the brain cells can last a few hours longer. Moreover, if the blood supply is returned in minutes or hours after the stroke, some of the cells can recover and if they do not, they also die (Go et al 28). A stroke is diagnosed by carrying out physical tests and studying the brain images produced during the scan. If a person is suspected to have stroke, a physician carries out various physical tests to determine the cause of it. This paper discusses stroke’s causes, and effects.
These types of strokes are the most common types of stroke. They occur when an artery supplying blood rich in oxygen to the brain becomes blocked. Blood clots forms in areas where the arteries have been blocked. For example, atherosclerosis is a disease condition in which fatty substance known as plaque deposits on the inner wall of the arteries. This plaque hardens and narrows the arteries thus limiting blood flow to the tissues and other organs such as brain and heart (Meschia 3-4). Plaque can crack or break open an artery. Blood platelets stick and clump together to the site of the plaque injury to build up blood clots. These clots can fully or partially block an artery. Another possible cause of the ischaemic stroke is atrial fibrillation which is a type of an irregular heartbeat. Atrial fibrillation causes the blood clots in the heart to break up escaping from the heart hence being deposited in the blood vessels supplying the blood to the brain. As one gets older, the arteries can naturally narrow. The risk of ischemic stroke is increased by many medical conditions (Sacco 4). There are things that accelerate the process of getting this stroke which include smoking, hypertension, obesity, diabetes, high cholesterol levels and excessive intake of alcohol.
Haemorrhagic stroke is also known as cerebral haemorrhages or intracranial haemorrhages.
