Hi, it's my first post- mum has had Alzheimer's for 4 years now. On arricept and not doing too badly however our biggest problem seems to the personal hygiene. She thinks she has washed when we know she hasn't, if I offer to help her she often refuses and the Carers we have often have the same problem. She is reluctant to change her underwear and will wear the same clothes for days. She used to be so particular.... Does anybody have any suggestions on how we can all deal with this? Thanks
