I do the same thing
and I know I don't have AD... but the stress of care giving and living in the modern world will cause you to rush through and miss even what you are looking for.
Funny story... I spent two days looking for a paper that I thought I had. I had the other 6 safely in the appropriate file folder and decided I had lost number 7. So I obtained a new form and sent it off to be signed apologizing for having lost the paper. Turns out I never got it!!! It had never been mailed to me
I just laughed at myself and kept going.
