What causes a cerebral aneurysm?

Cerebral aneurysms are typically caused by a combination of factors, including:

Genetics: Some people are more likely to develop cerebral aneurysms if they have a family history of the condition.

Age: Cerebral aneurysms are more common in older adults, especially those over 65.

Gender: Women are more likely to develop cerebral aneurysms than men.

Race: African Americans and Hispanics are more likely to develop cerebral aneurysms than whites.

Certain medical conditions: Conditions such as high blood pressure, hardening of the arteries (atherosclerosis), diabetes, and smoking can increase the risk of cerebral aneurysms.

Head injury: A head injury can damage the walls of blood vessels in the brain, increasing the risk of an aneurysm.

It's important to note that not all people with these risk factors will develop a cerebral aneurysm. However, it is important to be aware of your risk and to take steps to reduce it.
