Mum has AZ and VaD. She has recently been told she has a B12 deficiency and treatment will begin soon. She lives alone, her choice. This morning I called her as I always do at the same time to ask if she needs anything. She told me she couldn't sleep because there were explosions outside her house last night. I reassured her by suggesting it may have been a dream and not to worry. ( Mum lives in a very quiet area) She has also begun to mislay things and fret a lot about it. She is very determined to be independent and to continue living at home with her dog ( whose feeding bowl she now often loses). I'm at a loss to know how to support her without disturbing her remaining confidence. Any suggestions? Is it likely that this will continue, does it mark another 'stage' in her illness?
