What are the different types of stroke?

The two major kinds of stroke are acute ischemic and hemorrhagic.

There are two main types of stroke. An ischemic stroke is the most common and is due to a blockage of the blood supply to a part of the brain. Ischemic strokes are usually due to blood clots that stop blood flow or that break loose and travel elsewhere to block flow. The second type is called a hemorrhagic stroke and happens because weakened blood vessels rupture, preventing blood flow to areas of the brain.

A stroke can be categorized into one of two types: ischemic (due to blockage of an artery) or hemorrhagic (due to bursting of an artery). Ischemic strokes are the most common (85 percent), and of the hemorrhagic strokes, intracerebral hemorrhage is the most common, where there is bleeding into the substance of the brain due to bursting of an artery. Another type of hemorrhagic stroke is subarachnoid hemorrhage, which is most often due to bursting of an aneurysm that leads to bleeding in the fluid-filled space around the brain.

There are two main types of strokes, ischemic and hemorrhagic. Ischemic strokes happen when blood vessels become blocked. Hemorrhagic strokes occur when blood leaks into the brain through a damaged or abnormal blood vessel.

There are two types of stroke, hemorrhagic strokes and ischemic strokes. Hemorrhagic strokes result from bleeding inside the brain, which may occur if a blood vessel or aneurysm (a swelling in an artery) ruptures. Ischemic strokes, which are the most common type of strokes, result when a blood clot causes a reduction in blood flow in the brain. Both types of stroke are serious and require immediate medical attention.

There are two main categories of stroke: ischemic and hemorrhagic.
