Hi, I share the care of my mother who has mixed dementia with my brother, we do three month shifts each, this has been going on for a year since my dad died. We're now at the stage where mum doesn't know who anyone is, not me, not my husband or any of her grandchildren. I wonder what goes on in her mind, she knows we are all familiar and safe but she doesn't know any of our names. She never talks about anyone and she doesn't seem to miss dad or my brother when he's away. I find it very strange that I'm in her house, doing everything for her and yet she doesn't really understand who I am.
