Mum became very upset today and wandered out of the house, I was upstairs but my father got her quickly. She refused to come back in with him, then I saw what was happening and she came in with me. She has never wandered before. She becomes convinced sometimes that this is not her house (she's lived here for 38 years). Then becomes very distressed and thinks we are keeping her there against her will. Dad and I don't know what to do when this happens and all I seem to manage to do is loss my temper and yell that it is her home. This is weird as I'm a very placid person whom hates confrontation. Can anyone advise a sensible helpful way to deal with this? What do other people do? She also thinks my father isn't her husband sometimes and becomes very angry and upset. Can anyone advise how to deal with these horrible, distressing situations?
