do aneurysms cause strokes
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.
