My mum has dementia and most of the time she thinks I'm her sister who has passed away. She is 79 but thinks that she stills lives with her parents. Most nights she asks to go home. She has lived in this house for 35 years with my dad. When we try and explain that she lives with us and we are her family she says that we are lying and that she will never talk to us again. She has started to kick me. There is no reasoning with her that it's 11pm and she has no where to go. It sounds horrible but we try and ignore her until she calms down which is about 2 hours later. We know it's the disease and not her but it's very hurtful and upsetting. Any ideas on how else we can mange this behaviour please?
