One day, I decided to be brave and brought Mom out to lunch. It was special because Mom only heads out for medical appointments nowadays. (How did it come to this? Let me think about it and cover this in another post)
Anyway at lunch I put her to the test – and asked if she could still count. Yes, she could! From one to ten, and then backwards form ten to one, more slowly and with slight errors. She could add single digits, but when I asked her to minus, she couldn’t do this anymore. Ten minus eight is “I don’t know, eight?” Three minus two is… “???” She just couldn’t do it. She knew it sounded easy and was just as puzzled why she couldn’t manage it.
About 6 years ago, when I first brought Mom for screening because I thought she had early dementia, Mom could minus 7 from 100 all the way down. The tests pronounced her normal, but we knew she was already different.
She can no longer tell her own age nor understand who’s older or younger. But she loves a birthday cake and song, and happily joins in no matter whose it is.
