Stroke: Causes, Symptoms and Treatment

Battle occurs when it stops, or the blood flow to part of the brain is hampered, which deprives the brain tissue of the very necessary oxygen and other biological nutrients, and consequently the brain cells are exposed to death within minutes. Stroke is a medical emergency, and its immediate treatment is very important and important as it can reduce the brain and prohibit complications after stroke. Types of stroke There are two main types of stroke, knowing this: 1 ischeic stroke (this type of forms about 80% of the strokes, and this stroke occurs when the arteries of the brain are narrowed or clogged, which is a significant decrease in the amount of blood provided to the brain, and prevents the brain cells from leading the most common shopping. of blood to the brain, like the other veins in the neck and brain area. One of the upper heart halls, such as a result of the result for the result for the result for the result for the result of the upper heart sister, such as a result of the result for the result for the result for the result for the result of the result of the upper heart bell. Fibrillance, and lead to an imbalance in providing blood and to the formation of thrombosis. 2. Hemorrhagic stroke occurs this stroke when a blood vessel in the brain begins with bleeding or split, this bleeding can occur as a result of some medical conditions affecting the blood vessels, such as: untrained blood pressure and blood mothers (anurysm), and there is still a common cause of bleeding the tear of blood, which is the blood of the blood. Vessels are thin walls, leading to easily tearing. There are two types of hemorrhagic stroke: Bleeding in the brain in this type of stroke explodes one of the blood vessels in the brain, so that the blood flows in the tissue of the brain around it, causing damage to the brain cells, as well as the brain cells behind the leak, it does not get regular supplies of the blood damaged. Hyper pressure with time can cause a stroke of this type, and hypertension can make the small blood vessels in the brain fragile and more vulnerable to cracks and split. Underground bleeding in this kind of stroke begins to bleed in one of the large veins or in the surface of the brain, so that the blood flows in the space between the brain and the skull, and it is accompanied by a very strong and sudden headache. This type of stroke is often caused by one or more dirt or more blood mothers who can form and grow over time, or be morale. After the bleeding begins, the blood vessels can expand into the brain and narrow in an irregular way, which can cause the cells to be damaged by the extra decline in providing other brain with blood.
