Wow you must be reading my mind. This issue has come up with my Mom. Dad and I have discussed this over and over. My Mom was diagnosed at 76. (May 2008). At the time of diagnosis she was STILL working full time at the County Planning division with about 60 people who answered to her. She was sharper than a tack!
We had some issues with a few drug reactions that were given when she went into AFib and had to have a pericardial window procedure done. (She has lung and pericardial mets.) Those issues were addressed and the problem did seem to get better.
Now it seems as if she has aged mentally dramatically. She takes almost No meds. (Just Xeloda, a rare xanax, an 81 mg. aspirin and a blood pressure pill) She doesn't take any of the meds she was given for pain since she hasn't had any pain. (Methadone). She did have 5 rounds of Gemzar and Oxyiliplatin and Nexavar. She's now on Xeloda nonstop for 2 1/2 months.
She has moments that she can't get the word out or moments when she really seems to have dementia. (Her mother had dementia but she at least was 95 at the time).
We've mentioned this to the oncologists and doctors and have been keeping a close watch on the ammonia levels since that can cause similar symptoms. The levels have been normal. We even got a CT scan to r/o brain mets as well.
The symptoms seem to come and go with no rhyme or reason. It's definitely a puzzle.
I did speak with an oncology nurse that I work with and she did say that the shock of having and dealing with a terminal disease can exacerabate these types of symptoms. Who knows.......one more gift of this monster of a disease...
Hang in there.......
My Mom lost her one year battle with CC on April 3, 2009.
"A prognosis is simply an audit of how truly precious each day is. Live each day to the maximum, celebrate what was, and what is - Don't spend your life looking forward to what will or might be." .... words of wisdom from my beloved son on hearing of his grandmother's CC prognosis.
