@dogloverdude - welcome to Mayo Clinic Connect. I wanted to let you know I moved your post to this existing discussion where others were discussing someone they care about experiencing a stroke and an aneurysm:

- Aneurysm plus stroke https://connect.mayoclinic.org/discussion/aneurism-followed-by-stroke/

Hoping you can meet members here sick as @sharniegirl @mkoch @slowrunner1 @houston13. They may have input from watching their loved ones and other inpatients near them who may have experienced dementia like symptoms after stroke and surgical repair of an aneurysm.
