Stroke Archive

Strokes fall into two main categories: ischemic (which result from a blockage inside one of the brain's arteries and account for 87% of all strokes) and hemorrhagic (also known as bleeding strokes, usually from a ruptured blood vessel). Three main types of ischemic strokes are those that result from atherosclerosis in a large artery supplying the brain (large-artery atherothrombotic strokes); those caused by clots in the heart that travel to the brain (cardioembolic strokes); and those in the brain's smallest vessels (small-vessel strokes).
