A hemorrhagic stroke is one of two major stroke types. The other — called an ischemic stroke — is typically caused by an arterial blockage and is responsible for the majority of strokes. Both stroke types can cause lasting brain damage, long-term disability, and even death. However, early treatment can have a significant effect on outcomes. Therefore, it is critical to contact emergency services at the first sign of stroke.
Types of Hemorrhagic Stroke
- Intracerebral hemorrhage (ICH), the most common type of hemorrhagic stroke, occurs when a blood vessel in the brain leaks or ruptures (tears), allowing blood to seep into surrounding tissue. ICH has many causes, but it is most often the result of chronic high blood pressure.
- Subarachnoid hemorrhage (SAH) occurs when an artery located on the outer surface of the brain ruptures, allowing blood to leak into the fluid-filled space between the brain and the skull. The cause is often a ruptured cerebral aneurysm, a weakened area on an artery that bulges, fills with blood, and bursts open. The first sign of SAH is typically a severe headache that comes on suddenly with no known cause.
