Basically, my dbro and I have taken my mother abroad to where she is from.as she needed to sell some property so we accompanied her to help out. Basically, she has been rude and argumentative throughout. She flies off the handle at the slightest thing. For example, she wanted to take an empty bag for life home, even though she has a thousand and she has limited room in her suitcase. We just said' why bother taking a 20p bag all the way home and she went mad. I can't remember why she told us this morning that we were terrible people but it was again something trivial. The thing is, my dad passed away 2 years ago, and she constantly harangued and bitched about him, shouted and ranted at him, so I don't know if she is just transferred all that to us. She co stantly tells us the same thing over and over again but again she's always done this to dome extent. She is very controlling and has to micromanage everyone but it makes it very difficult to judge whether it's just her or whether she's developing dementia. She is diabetic but eats sugary shit all the time. Again, if we point it out she replies by flying off the handle so we don't bother anymore. I know that poorly controlled diabetes does cause dementia. My friends mum was very similar personality wise. She said when her mum got dementia she turned into a much nicer person, and when she died, they were finally able to have a nice e time together for the first time in years! DM is 76.
