Hemorrhagic Stroke
Hemorrhagic strokes are caused by rupture of small blood vessels that supply blood to the brain. Hemorrhagic strokes are more common in those who have high blood pressure. This type of stroke tends to be much more serious than an ischemic stroke.

Hemorrhagic strokes damage the brain in two ways:

• Loss of blood supply
• Effects of bleeding:
• Bleeding within brain tissue causes swelling and increases the pressure against the brain.
• The pressure directly injures brain cells.

Hemorrhagic strokes account for about 15 percent of all strokes. One type of hemorrhagic stroke, a subarachnoid hemorrhage, accounts for about 5 to 7 percent of all strokes.
