hello. I am hoping that someone out there has experience of this situation and can give us the benefit of their experience. My 90 year old mother in law has moderate dementia. She lives alone but has carers and volunteer visitors every day., she goes out for lunches and visits. She is well looked after and happy in her own home where she has lived for 55 years. She has three children, one lives 200 miles away, one lives in Spain and the third lives close to her mother. Very sadly my sister in law who lives close by is now very seriously ill and has a prognosis of just a few months. Mother in law does know that her daughter is ill but we have been able to say truthfully that she is quite ill, having to rest and aren’t unable to drive and she quickly forgets. When mother in law first realised that she was ill because she saw her, she rang her house repeatedly but over time she seems to have forgotten. Our dilemma is whether to tell her or not. I feel that it would cause her unnecessary stress and she may decide to get on a bus to visit or start ringing my sister in laws house again.There are absolutely no other family members nearby and we are trying to manage her situation at a distance so this makes things really hard. My husband and his sister want to do the right thing but do not want to cause a unmanageable breakdown particularly given the distances involved and her present happy situation. Please could you give us the pros and cons of telling her or not telling her from your own experience and benefit of hindsight? Thank you.
