Hi
I can tell you of what I have experienced
I had no symptoms while my aneurysm was unruptured didn't even know I had one untill the day it ruptured, most people are like me and have no symptoms.
After the rupture was a different story, mentally I had alot of trouble with word searching and my thinking process, I am still not as sharp as i was pre aneurysm. My moods have suffered too and I went through a depression and went to mental health counseling and take medication for it but I am fighting my way back.
Do you have a plan to have yours fixed? good luck to you and sorry you have an aneurysm
