Whenever my husband contradicts something I say I just let him have his way and something like 'I must have remembered wrong' or something along those lines and let him think he is right. It's just not worth the extra work in trying to convince him that I am right and it makes him feel better that he can remember things.

I do believe it is a common thing with dementia.

Hi- Have you considered accepting her "no" and redirecting the conversation? Maybe she sees you as when you were much younger. So sorry.

I used to apologise for getting it wrong, allowing us to move on. Worked every time :)

My mom is 100 at end of month and lives in LTC....has mild cognitive impairment and what she enjoys is talking about years ago and sharing old pictures

I use baby monitor so I can hear her and got a camera that shows me what she's doing at any given time anywhere I'm at. You downloaded the app to your phone. I have found this very helpful...
