Types of Stroke

There are different types of stroke:

Ischemic strokes account for about 83 percent of all stroke cases. The underlying cause for this type of stroke is an obstruction of fatty deposits lining the vessel walls. It is treated by removing the obstruction and restoring blood flow to the brain. Transient ischemic attacks (TIAs) occur when a vessel clogs for a short time and resolves itself. TIAs are often warning signs of an ischemic stroke.

Hemorrhagic strokes account for about 17 percent of stroke cases. These strokes result from weakened vessels that rupture and bleed into the surrounding brain. They are treated by introducing an obstruction to prevent rupture and bleeding.
