Intracranial aneurysms are abnormal bulges or balloon-like dilations in the blood vessels of the brain. These weak spots in the blood vessel walls can potentially rupture and cause bleeding in the brain, leading to serious health complications such as stroke, brain damage, or even death. Research in this area focuses on understanding the risk factors, causes, and mechanisms of intracranial aneurysms, as well as developing effective diagnostic and treatment approaches to prevent rupture and improve outcomes for patients. This research may involve studying genetics, imaging techniques, and novel therapies such as endovascular coiling or surgical clipping.
