What causes aneurysms?

Aneurysms can be congenital – that is, people can be born with them.

More often, they are due to a gradual weakening of the wall of an artery or vein. This can be due to high blood pressure, or high cholesterol levels, or smoking. An aneurysm can also be caused by an accident or injury that damages the artery or vein such as a head injury.

Aneurysms are more common in some families than others.

They can also occur with certain medical conditions such as polycystic kidney disease and some connective tissue disorders.

Drug abuse (e.g. cocaine abuse) can also cause a brain aneurysm.
