Overview of Hemorrhagic Stroke
Introduction
Hemorrhagic strokes include bleeding within the brain (intracerebral hemorrhage) and bleeding between the inner and outer layers of the tissue covering the brain (subarachnoid hemorrhage). (See also Overview of Stroke .) Most strokes are caused by a blockage of blood flow to part of the brain causing death of brain tissue (ischemia). Such strokes are called Ischemic Stroke . Only about 20% of strokes are caused by hemorrhage. There are two main types of hemorrhagic strokes: Intracerebral Hemorrhage None Subarachnoid Hemorrhage (SAH) None Other disorders that involve bleeding inside the skull include Epidural Hematomas and When blood vessels of the brain are weak, abnormal, or under unusual pressure, a hemorrhagic stroke can occur. In hemorrhagic strokes, bleeding may occur within the brain, as an intracerebral hemorrhage. Or bleeding may occur between the inner and middle layer of tissue covering the brain (in the subarachnoid space), as a subarachnoid hemorrhage.
