Hemorrhagic stroke is a result of a rupture of a blood vessel within the brain. The hemorrhage can be caused by an aneurysm (weakened blood vessel wall), vascular malformation, hypertension, or from a traumatic event., One type of hemorrhage is a subarachnoid hemorrhage where bleeding occurs in the space between the brain and the cranium in an area called the subarachnoid space. This type of hemorrhage is usually observed when an aneurysm ruptures.
