Overview of Hemorrhagic Stroke
Topic Resources
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 strokes. Only about 20% of strokes are caused by hemorrhage.
There are two main types of hemorrhagic strokes:
Other disorders that involve bleeding inside the skull include epidural hematomas and subdural hematomas, which are usually caused by a head injury. These disorders cause symptoms that sometimes resemble those of a stroke.
