Mom is in stage 5/6 Alz and recently had a mini stroke. Sort of out of the blue, mom asked me to buy her a watch the other week, so I bought her an analog watch similar to what she had several years ago. When I brought it to her, she said the hands were too small. So I returned it for a digital that was much larger. But although she didn't outright admit it, it appeared she couldn't tell the time with this watch either, even though she could see the numbers and read them to me one by one. It hit me as a surprise. Is this a normal progression for ALZ?
Most people with dementia loose the meaning of time. You can give her the classic test and see...ask her to draw a clock with the 12 numbers. Ask her to draw a big hand and small hand with the time something like 2:40 and see if she is capable.
