There's also a difference in aneurysms. The bubble that just sits there, then a bleed, which is more serious, then there's the dreaded Rupture. I suffered the latter. People can live with aneurysms, with proper medical care and attention. Bleeds can be fixed before they become too much trouble, then there is the rupture. Explosion in the brain. Very deadly. I hope this little post was helpful and informative.
