Cerebral aneurysms are abnormal bulges or weak spots in the walls of blood vessels in the brain. These bulges can become enlarged and may rupture, causing bleeding into the brain (known as a hemorrhagic stroke) and potentially leading to serious complications or death. Research in this area aims to better understand the risk factors, causes, diagnosis, and treatment options for cerebral aneurysms in order to improve outcomes for patients. This includes studies on genetic predispositions, imaging technologies, surgical techniques, and endovascular procedures for treating cerebral aneurysms.
