Hemorrhagic Stroke

A hemorrhagic stroke happens when a blood vessel in the brain bursts and spills blood into or around the brain. High blood pressure and aneurysm (a weak or thin spot on a blood vessel wall) can make blood vessels weak enough to burst. There are two types of hemorrhagic stroke: subarachnoid and intracerebral.

Subarachnoid Hemorrhage: In a subarachnoid hemorrhage, an aneurysm bursts in a large artery on or near the thin, delicate membrane surrounding the brain. Blood spills into the area around the brain, which is filled with a protective fluid, causing the brain to be surrounded by blood-contaminated fluid.

Intracerebral Hemorrhage: In this scenario, bleeding occurs from vessels within the brain itself. Hypertension (high blood pressure) is the primary cause of this type of hemorrhage.
