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.
In other cases, an unruptured aneurysm will cause problems by pressing on areas in the brain. When this happens, the person may suffer from severe headaches, blurred vision, changes in speech, and neck pain, depending on what areas of the brain are affected and how bad the aneurysm is.
