Close Up of a Cerebral Aneurysm
Cerebral aneurysms can occur in anyone at any age, but they are most common in adults age 30-60 and are slightly more common in women than in men. An unruptured cerebral aneurysm can cause problems by putting pressure on a nerve or on surrounding brain tissue, causing pain near the eye, vision changes, numbness, weakness, or paralysis on one side of the face. Many cerebral aneurysms are small and don't cause any problems, but all have the potential to rupture and cause bleeding in the brain.
