Strokes are caused by 1. Thrombosis (blood clotting) 2. Embolism (a travelling Clot or other in the circolatory systems) 3. Haemorrhage (bursting of a blood vessel.
Each one of these three causes have each multiple causes and the effects depends upon the particular area involved and the extent involved.

A stroke, or brain attack, is an injury to the brain. It occurs when blood flow to the brain is stopped because of a blocked or broken blood vessel. Brain cells need oxygen. When everything is working right, blood carries oxygen to the brain. If the blood flow to the brain is cut off, brain cells: don't get oxygen, begin to die. There are basically two types of strokes, Ischemic stroke and Hemorrhagic strokes. Ischemic strokes happen when a blood clot or buildup of fatty substance stops blood flow to the brain. The blockage may be in an artery in the neck or brain. Of a clot can form in another part of the body and travel to the brain. A Hemorrhagic stroke happens when a weak spot in a blood vessel breaks. Blood spills into or around the brain. The most common causes of stroke are: high blood pressure, carotid artery disease (narrowing of the arteries in the neck that bring blood to the brain), atrial fibrillation (irregular, often rapid heartbeat), diabetes and heart disease. Some less common causes might be creating a blood clot which breaks away and travels to the brain, narrowing blood vessels, which can block blood from flowing to the brain, and weakening blood vessels which can lead to a break. Ways to reduce your chance of getting a stroke is: eating a healty diet, getting regular exercise, maintaining a healty weight, limiting alcohol use, quit smoking, take all medication as ordered by MD and see your MD annually at least.
