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.

An aneurysm is an abnormal swelling or bulge in the wall of a blood vessel, such as an artery. It begins as a weak spot in the blood vessel wall, which balloons out of shape over time by the force of the pumping blood. Usually, aneurysms develop at the point where a blood vessel branches, because the ‘fork’ is structurally more vulnerable.

Stroke - Lab Tests Online AU

Stroke occurs when the blood supply to a part of the brain is suddenly blocked or diminished, altering the body function controlled by that area of the brain. If any part of the body including the brain is without a source of fresh blood and oxygen, the cells will be injured and may die. Although some cell injury is reversible, the death of brain cells is permanent, usually leaving lasting disability.
