Aw jogging I really do feel for you, and your darling mum. I'm sorry to say but probably not. It is heartbreaking to have to go through. Probably more for you than for her, I suspect. Is she in a place where there are carers? Does she have any meals cooked for her?
My dad was in a place where he had his own flat but went downstairs to the dining room for his lunch, which he loved. They also had social nights and parties, although he was only there for 12 months. He did love it there though, even though he had dementia too. The carers seemed very good with him, he used to joke with them and he enjoyed their company.
Has your mum got plenty of photos of you all around her? Try to let her keep as much of her own things as possible. I tried to buy new things for my dad when he moved, thinking it would cheer him up, but it was the wrong thing to do, and just got him agitated as he wanted his own things around him, even his old sleeping bag over his knees. Whatever makes her happy.
The one thing I learnt about dementia is not what you do for someone but how you leave them feeling. So if you can, try to leave her feeling relaxed, happy as much as possible, even on a phone call. I tried to joke with my dad, get him laughing. But don't feel bad if this doesn't happen for some reason. If there are carers, then phone them a short time later and see if they will check on her, put your mind at rest. I suppose it's a little like checking on a child in school when they are unsettled. It is hard, very hard and will be with you for some time. Don't beat yourself up about it, you are doing your best. She is safe, looked after and you are visiting and phoning. You can't do any more. Look after yourself, take care of you. Treat yourself a little, it is a rough ride to go through. Lots of love and best wishes. Xxx
