A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk for an aneurysm or, if you already have an aneurysm, may increase your risk of it rupturing:
People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't.
People who have had a brain aneurysm are more likely to have another.
Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage.
African Americans are more likely than whites to have a subarachnoid hemorrhage.
High blood pressure.
The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure.
In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.
