I am in a dilemma as to how best to deal with the situation. I live in France and she is in the UK. Her husband has refused to listen to his children's concerns and as far as we know nothing is being done to diagnose whether she has dementia of some sort or something more simple that could be treated. She suffers with depression, short term memory loss and confusion, and one or two examples of inappropriate behaviour. I am worried that if I write to her her husband will be furious and aggressive which he has been towards his children when they expressed concern over her condition. She suffered badly with polymyalgia rheumatica for three years - treated with steroids - and then had to have a hip replacement one year ago. She is timid, takes no joy in life and is completely changed from the intelligent, dynamic person she was. She is my twin, we are both about to be 70, I don't want to cause a family eruption and distance her and her husband even more from the rest of the family. Any suggestions? Thanks.
