Hi, My mum was recently diagnosed with Alzheimer's at 75, and she is at the moderate stage. We have noticed the signs for about the last three and a half years, but she has got worse in the last 9 months. She started to forget who my dad is a few months ago, and is starting to forget who me and my siblings are at times. Over the last few days, she has been seeing dad as a complete stranger and has even said that she wants to phone the Police to get him to go! She keeps asking him where he lives and gets upset about it, especially at night. Myself and my brother and sister keep saying that he is her husband of 56 years, but she is adamant that he is not. Even after showing her photo's, she still says that he is a stranger. Today, I spoke to her and she says she wants to move and live with her sister (who lives locally), who has carers herself due to a physical condition. We have convinced her for now that this would not be a good idea, but we are worried that she is getting so stressed with dad and also how this is affecting dad (he is 81 years old).
