most common stroke type
Types of Stroke. The most common type of stroke, accounting for almost 80 percent of all strokes, is caused by a clot or other blockage within an artery leading to the brain. An intracerebral hemorrhage is a type of stroke caused by the sudden rupture of an artery within the brain. Blood is then released into the brain compressing brain structures. A subarachnoid hemorrhage is also a type of stroke caused by the sudden rupture of an artery.
