Hemorrhagic strokes happen less often than ischemic strokes. A hemorrhagic stroke is caused when a blood vessel bursts and blood spills in the brain. The blood in the brain causes increased pressure and swelling which causes damage to the brain.

Intracerebral hemorrhagic strokes

These strokes when a blood vessel leaks blood into the brain. They are most often the result of high blood pressure exerting excessive pressure on the vein walls already damaged by the hardening or narrowing of the arteries (atherosclerosis).

Subarachnoid hemorrhagic strokes

This kind of stroke is usually caused when an aneurysm bursts, leaking blood into an area between the brain and the skull (the subarachnoid space). An aneurysm is when a blood vessel has a weak spot making it easier to burst.

Diagnosing hemorrhagic strokes

To help find the source of the bleeding, there are diagnostic tests like CT and CTA scans. The CT scan helps show the location and size of the blood as well as any brain swelling. The CTA looks at the brain's blood vessels and helps show if the bleeding was caused by a malformation in a blood vessel.
