Mum has vascular and Alzheimer's mixed dementia. I have noticed over the last few weeks she seems to be getting frailer noticeably that is. This last week has been really noticeable and the doctor has been out. UTIs ruled out and no chest infection just her 'usual' headaches but she has had these for as long as I can remember so way over 20 years. She is finding it difficult now to pull up her depends (we have a different name but thats what I mean) and has just taken a tumble - not hurt just a tumble...but is this the start of a new phase?
