Just what is an aneurysm? It's a weakened portion of a blood vessel. Aneurysms can occur in various places throughout the body, but cerebral aneurysms are especially dangerous. If they burst and bleed - an event known as a subarachnoid hemorrhage - they can be deadly.
How deadly? The Brain Aneurysm Foundation estimates that of 40 percent of the 27,000 Americans who suffer a ruptured cerebral aneurysm die outright. Most of those who survive are left with permanent brain damage.
That's scary stuff, especially if you have an aneurysm or a family history aneurysm - or if you're experiencing pain behind the eye or other symptoms of cerebral aneurysm. But for the general population, experts say there's little reason to worry.
Even if you blow your nose.
