What Is Hemorrhagic Stroke?
The two primary types of stroke are hemorrhagic (bleeding) and ischemic (blockage). Ischemic, the more common of the two, happens when a brain artery is blocked. Hemorrhagic stroke is a burst blood vessel in the brain caused by an aneurysm (weakened bulge in a blood vessel) or high blood pressure.
The two types of hemorrhagic stroke are:
- Intracerebral: A blood vessel inside the brain ruptures or leaks.
- Subarachnoid: A blood vessel on the surface of the brain ruptures or leaks, causing bleeding between the inner and middle layers of the membranes covering the brain.
In both types of hemorrhagic stroke, leakage of blood causes brain swelling and an increase of pressure in the skull. This pressure and inflammation damages brain cells and tissue.
The Northwestern Medicine neurosciences programs provide care for neurovascular conditions including:
- Acute hemorrhagic and ischemic stroke
- Transient ischemic attack (TIA)
- Subarachnoid hemorrhage and cerebrovascular malformations
This includes advanced diagnostic imaging, multimodal treatment and rehabilitation for patients with stroke and cerebrovascular disease.
