Finally having a diagnosis is making it a lot easier for the two of us to communicate about what's going on and how we feel about it.
That makes sense.
I've gone through transition periods with each of my parents where they didn't realize they weren't as sharp as they thought they were. It mostly had to do with memory issues. It was a huge relief when rather than having repeated conflicts about whether something did or didn't happen, they finally started saying "well, I really thought X happened, but my memory these days...."
My own memory is definitely less sharp now than it used to be, already, which I'm not enjoying. Mostly, I have to make lists -- I used to be able to keep dozens of things on my mental checklist and they'd stay there until completed, that's no longer reliable.
Anyway, best of luck to both of you.
