Guide to a Brain Aneurysm

An aneurysm is a weak spot in one of your brain’s arteries (blood vessels that carry oxygen from your heart to the rest of your body). They tend to happen where arteries fork. Over time, flowing blood puts pressure on that spot and makes it give way and balloon out. It’s a lot like a worn-out garden hose that bulges where it’s gotten thin. Most people who have an aneurysm don’t know it. But if it bursts, it can be life-threatening and cause brain damage.
