Overview
A brain aneurysm is a berry-shaped swelling in a cerebral artery. Normally, arteries, like hoses, are strong and elastic. An aneurysm occurs when a section of an arterial wall weakens, expands outward, and bulges.
Aneurysms can form in a variety of locations throughout the body, such as the biggest artery in the abdomen (abdominal aortic aneurysm) or an artery in the head (brain aneurysm). Brain aneurysms frequently occur as the arteries that feed blood to the brain break and branch off.
Many people who have a brain aneurysm are unaware of it. Others, on the other hand, feel symptoms or their aneurysm is more prone to rupture (burst) and cause life-threatening bleeding in the brain. Treatment is occasionally recommended to prevent such ruptures and ease symptoms.
