The bleeding causes swelling of the brain and increased pressure in the skull. The swelling and pressure damage brain cells and tissues. Examples of conditions that can cause a hemorrhagic stroke include high blood pressure, aneurysms, and arteriovenous (ar-TEER-e-o-VE-nus) malformations (AVMs). Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood.
Most aneurysms remain small and are never diagnosed. Some, however, may gradually become larger and exert pressure on surrounding brain tissue and nerves and may be diagnosed because of stroke-like symptoms including: 1  headache, 2  numbness, or weakness of one side of the face, 3  a dilated pupil, or. 4  change in vision.
