2011-brain-aneurysmA brain aneurysm is a weak bulging spot on the wall of a brain artery much like a thin balloon or a weak spot on an inner tube. As the artery has thinned, the pounding of the blood flow through the artery weakens the artery. The blood flow causes the weakened artery wall to swell outward. This is very painful for the individual. This extreme pressure on the weakened artery, may cause the aneurysm to rupture and allow blood to escape into the brain. This is a very serious condition that will require advanced surgical treatment, a coil or a clip.
