Brain Aneurysm

Overview

A brain aneurysm, or cerebral aneurysm, is a localised weakening and ballooning of the wall of a blood vessel in the brain, forming a thin-walled sac that fills with blood. Many aneurysms remain small and cause no symptoms, but if the weakened wall ruptures it can bleed into the space around the brain, producing a subarachnoid haemorrhage, a form of haemorrhagic stroke that is a medical emergency and can lead to severe disability or death. Risk factors include high blood pressure, smoking, family history, and certain inherited conditions, and management ranges from monitoring of small, stable aneurysms to surgical clipping or endovascular coiling to prevent or treat rupture. Because ruptured aneurysms are a leading cause of non-traumatic subarachnoid haemorrhage, neurological research devotes considerable attention to the cerebral vasculature, the mechanisms of vessel-wall failure, and the recognition and treatment of intracranial bleeding. This page gathers peer-reviewed, open-access neurological research relevant to cerebrovascular disease, intracranial haemorrhage, and the broader study of conditions affecting the blood vessels of the brain and their consequences for neurological health.
