My Mom is 92 and in early stages of dementia (not Alzheimers - multi infarct dementia per the doctor). Part of her problem is confusion and part is word-finding difficulties. Is it helpful or even useful to ask her questions or give hints to help her clear up her confusion? Example: she looks at the clock at 6 pm and says it's "60 minutes". When I ask, she can tell me it was 5 o'clock an hour earlier and will be 7 o'clock and hr later, but still has trouble making the leap to 6 o'clock. Should I try to help her come up with 6 o'clock on her own, or just give her the answer? Does it help preserve brain function to have her come up with the right words (as in use it or lose it) or is it going to be too frustrating for her?
