If he is not looking after her properly and she has dementia then she is at great risk in my view.
If she loses her memory whilst cooking she could set fire to the house, have an accident while cleaning etc and could be in all sorts of perils.
I would be looking into 24 hour care in a proper facility for her and then the son would have to leave the public housing and a low income family could benefit from that.
Time he stood on his own two feet anyway.
Thanks for your thoughts on this. Yes....totally agree that she needs 24 hour care and I am in the process of organising this.
"Time he stood on his own two feet anyway."
He's 63 years old and I doubt if there's much hope of him learning to stand on his two feet. It is not the first time he has exploited his mother and his family.
