Mum has altzheimers and Dad is her carer, they are 86 and 84 respectively. Quiet often now Mum says she's going home or going to see her Mum, so Dad accompanies her for a walk and eventually they come back to their home. this has been happening for about two months. This evening Mum decided that the house was not where she lived and she was going home, it is very icy tonight so not a good idea to go out walking, so Dad told her the house was where she lived and had done for 14 years, but she would not have it. My brother had to go down to help Dad, but she said he was talking rubbish too He showed her letters addressed to them at that address and she even said she was going to have to speak to the bank, as they were sending statements to the wrong address! According to Mum everyone else was wrong. Eventually she calmed down and agreed with me that they did actually live at that address. We are worried that this will get worse and to be quite honest, Dad cannot cope with it. He does an amazing job with her, but when she is like she was this evening he doesn't know what to do and we didn't either. Any help please?
