There are three main types of stroke: transient ischemic attack, ischemic, and hemorrhagic. Itâs estimated that 87 percent of strokes are ischemic. Doctors also call a transient ischemic attack (TIA) a warning or ministroke. A clot that temporarily blocks blood flow to your brain causes a TIA.
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.
