Hemorrhagic StrokeA stroke occurs when the flow of blood to part of the brain is cut off or significantly reduced. Without the oxygen carried by the blood, brain cells can die quickly, which can cause permanent brain damage. Strokes can be major or minor and the consequences can range from complete recovery to fatality.
Hemorrhagic strokes make up about 13 percent of stroke cases. It’s caused by a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.In an ischemic stroke, blood supply to part of the brain is decreased, leading to dysfunction of the brain tissue in that area. There are four reasons why this might happen:
