Hemorrhagic Stroke

Hemorrhagic stroke occurs when an artery in the brain bursts. This blood loss damages the brain. It may also cause a sudden increase in the pressure inside the skull. Death or symptoms ranging from severe to mild can result, depending on the amount of pressure. Hemorrhagic strokes can occur in different ways. Cerebral hemorrhage is the rupturing of a brain artery that results in bleeding into the surrounding area of the brain. Bleeding can be caused by a burst cerebral aneurysm (blood-filled pouch in the wall of a blood vessel) or a head injury. A subarachnoid hemorrhage occurs when a blood vessel on the brain’s surface ruptures and bleeds into the space between the brain and skull.
