These are strokes that are caused by a rupture in a blood vessel in the brain. This occurs when a blood clot forms somewhere in the body and then travels to the brain and blocks blood flow.Ībout 13 percent of strokes are hemorrhagic. Another cause of ischemic strokes is an embolism. A blood clot can form in the narrow arteries and block blood flow. This can happen when the arteries in the brain narrow due to a condition such as atherosclerosis. An ischemic stroke is caused by lack of blood flow to brain tissue. There are two types of strokes: ischemic and hemorrhagic. Strokes can be major or minor and the consequences can range from complete recovery to fatality.
Without the oxygen carried by the blood, brain cells can die quickly, which can cause permanent brain damage. A stroke occurs when the flow of blood to part of the brain is cut off or significantly reduced.
