A brain aneurysm (also called a cerebral aneurysm) is a blister-like bulge in a weak part of a blood vessel in your brain. It can go unnoticed for a long time. In fact, 1-6 percent of Americans has an aneurysm they don’t know about. If left untreated, however, the pressure of the blood causes that area of wall of the blood vessel to become even weaker, which allows the aneurysm to grow. Eventually the aneurysm may burst, which causes a stroke.
