Age and gender are important risk factor that leads to cerebral aneurysm.

• About 5% of the population has some type of aneurysm in the brain, but only a small number of these aneurysms cause symptoms or rupture.

• Cerebral aneurysms occur more commonly in adults than in children but they may occur at any age.

• They are slightly more common in women than in men.
