A stroke occurs when the blood supply to the brain is reduced. This deprives the brain of oxygen and nutrients, which causes the death of brain cells. A stroke may be caused due to a blocked artery (ischemic stroke) or due to the leaking or bursting of a blood vessel (hemorrhagic stroke). Thrombotic stroke occurs when a blood clot forms in arteries which leads to reduced supply of blood to the brain. How a person is affected by their stroke depends on where the stroke occurs in the brain and how much the brain is damaged.People who have larger strokes may be permanently paralyzed on one side of their body or lose their ability to speak. Some people recover completely from strokes, but more than 2/3 of survivors will have some type of disability.
