My ex husband was diagnosed with Alzheimer's about 4 years ago. Myself and our children now realize that the onset was probably showing signs a few years before that diagnosis. We have always had a good relationship after our divorce and shared many happy family gatherings and occasions. He has been a great help to me in difficult times as I have been to him. He still lives on his own but I go round everyday, helping with cleaning, washing, shopping and general day to day activities. For the last few weeks/months he has said he is showering and he is not. We make sure there are clean clothes, plenty of underwear/socks and outer wear. We just don't understand why he says this. He keeps buying shower gel to convince us he is using it but clearly isn't. Don't know how to deal with this anymore?
