Hi,
My Mom was 79 - diagnosed in January 2009 and passed away on May 21, 2009 - I miss her terribly.
She went through the radiation and chemo - got so sick and just couldn't do it anymore - came home because she was in Florida when this all happened - started radiation again but no chemo and did about 10 treatment and by that time was on decadron - she was weak, short term memory loss, began to fall alot, urination problems, not being able to hold it...this comes with it. The decadron cause lots of muscle weakness but they do feel better. Anyway, Mom stopped everything and lived 2 weeks and 2 days after entering nursing/hospice home. It was heartbreaking but I think even she knew she couldn't fight it - it was the hardest thing in the world for me and my family. My sister and I both took care of her and Dad too, of course. It just happened all so fast and that beast just took her.
Good luck to you - I hope your Mom improves!
Hugs,
Rita
