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.
Ischemic Stroke. Approximately 80 percent of strokes, or brain attacks, are ischemic. They can develop in major blood vessels on the surface of the brain (called large-vessel infarcts) or in small blood vessels deep in the brain (called small-vessel infarcts). Specific types of ischemic stroke include embolic infarct, thrombotic infarct, and lacunar infarct.
