My Gran is in her 90's and is about 5 years old in her brain for the most part now. She asks to see her mum, dad and "the children" often. We can't tell lies to her as if you put her off and say we'll see them later or tomorrow she stays up all night trying to get to them. She gets violent with my dad now. She is tiny so she can't really hurt my dad physically but mentally is another thing. My mum and dad (her son) are her full time carers. She gets very angry and doesn't believe or trust them anymore. She thinks they are lying to her or keeping her locked in the house. I bought her a twiddle muff to see if it would help calm her but she never had toys and things as a child so she doesn't know what to do with it and just places it on the table. They have always stayed calm with her and try and show her what they can. I.e. when she wants to go downstairs they take her round the house to show her she is on the ground floor. The more agitate she becomes the less she sleeps. The dr has finally had to give her sleeping tablets as the lack of sleep meant her whole body was shaking and she was struggling to walk. They do work but she can only have a short course and the long term ones don't work. The dr says apart from the Alzheimer's she is perfectly healthy. He says her heart, blood tests and body are really good for her age. So it looks like this could carry on for a long time to come. It's really not fair on her never mind everyone else.
