Brain conditions

Cerebral aneurysm

Your brain and spinal cord are supplied blood by major blood vessels known as arteries and veins. Blood vessels allow blood to travel to all parts of your brain to provide it with oxygen and energy.

A cerebral aneurysm occurs when a point in an artery in the brain swells. A point in a brain artery can swell because part of an artery wall has become weak. Cerebral aneurysms can be caused by disease or injury, but other times they occur because someone has been born with this predisposition.
