Illustration showing locations of a haemorrhagic stroke. An aneurysm occurs when the arterial wall weakens causing it to stretch and bubble up. A subarachnoid haemorrhage occurs when blood fills the spaces between the brain and the skull. Hypertension is the elevation of blood pressure that can cause arterioles to burst. The tissue around the rupture begins to die and leak causing more bleeding. | |
