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.
The clot interrupts blood flow and causes a stroke. Two types of thrombosis can cause a stroke: large vessel thrombosis and small vessel disease (or lacunar infarction.) Large Vessel Thrombosis: This is the most common type of thrombotic stroke. It is caused by a combination of long-term atherosclerosis (hardening of the arteries) followed by rapid blood clot formation.
