What Causes a Brain Aneurysm?

Brain aneurysms can be congenital (present at birth or developing thereafter) resulting in an abnormality in an artery wall. The NIH reports that brain aneurysms are also more common in people with certain genetic diseases, such as connective tissue disorders and polycystic kidney disease, and certain circulatory disorders, such as arteriovenous malformations (snarled tangles of arteries and veins in the brain that disrupt blood flow).
