My mum was diagnosed with Alzheimer's approx 18 months ago. At first it was just little things - she didn't understand how to use the cableless phone, misplaced things. Now its got worse. I looked after her for my dad last night as she decided she didn't want to be on her own as he had to go out. Most of the evening she couldn't remember my name, she kept getting confused as to why she was there, where dad was etc & at one point told me she didn't know where her family had got to as they knew we were coming - she was at my house. I found this to be very distressing and am unsure how to react to her. Do I tell her the true facts or go along with what she is saying? Anyone that can give me advice would be much appreciated. Thanks.
