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 Ischemic stroke is the most common type of stroke, accounting for a large majority of strokes. There are two types of ischemic stroke: thrombotic and embolic. A thrombotic stroke occurs when a blood clot, called a thrombus, blocks an artery to the brain and stops blood flow. TIA is a temporary cerebrovascular event that leaves no permanent damage. Usually it entails an artery to the brain is temporarily blocked, causing stroke-like symptoms, but the blockage dislodges before any permanent damage occurs. Symptoms of a TIA may be similar to a stroke, but they resolve quickly.
