My mam has been in a dementia bungalow for nearly 5 months and she seemed to be settling in but has started asking when is she going home to her mam's house. The carers keep saying not today. Is that not giving her hope that one day they will say yes when it really isn't the case?
I saw this going on with another woman where our mother is (the MC unit has only been open a year now, AL/IL earlier, after a complete tear-down and rebuild) - this woman would go up to anyone visiting and ask if we could give her a ride to see her mother who was bed-ridden. It was kind of apparent that it was not likely her mother was still living, but I did confirm it later. For about 9+ months our mother would hound my younger brother about going back to her own condo (thankfully she hounded him, not me!) One day while visiting, out of the blue she asked me if I could drop her off at Nana's on my way home... Nana was her mother, gone now about 40 years. I just looked at my watch and said 'oh, it is kind of late today and not exactly on my way home... maybe tomorrow.' Her response was just oh, ok.
In a way, yes, it is giving them hope. However depending on the level of short-term memory loss, it is likely forgotten quickly that the discussion even happened. A few minutes later she asked me if I had keys to the place they owned before the condo - sold 23 years ago. Again... fib, little white lie, whatever you want to call it - it satisfies (most of the time) the request, for now and move on to something else. In this instance I pulled up my key lanyard and just said 'oh, no, not with me. I'll check when I get back home.' She accepted that and just said that she would stay there tonight if she only had a key. The staff has told me that she has talked of going (walking) to her mother's place and once was so adamant that she got her coat and purse and was going to walk there now! A little ingenuity got them over the hump (it was late, dark and many miles to go, in a different state, better wait for tomorrow!) She has alluded to her mother several more times since then (wanting to save a balloon for her, asking if she had a tree for Christmas, etc.)
We do not know/see/interface with your mom, but if she accepts the answer and moves on, then yes, the responses are fine. If she starts to get angry or balk at this answer, they'll have to change tactics.
Have you heard of Teepa Snow? She produces wonderful YouTube videos on how to best deal with some forms of dementia symptomotology.
Your mam won’t remember that they have already given her that answer. She lives in the moment. If that answer satisfies her, it’s a good answer.
Hope is a wonderful thing for all of us to feel.
Hugs to you and your mam.
