Although my oh has only recently been diagnosed with Alzheimer's. Her behaviour has deteriorated fairly quickly especially getting agitated or even angry over silly things that don't really matter. E.g.. next door are having some work done in rear garden,the man doing the work used our wheelbarrow not realising it wasn't our neighbours! Our neighbour as soon as he realised came round to apologise. I said it wasn't a problem the barrow was old and we hadn't used it in years, he said he would get the guy to clean it when finished. Anyways the barrow didn't get cleaned,not really a problem as we were going to throw it anyways. However my oh has fixated on this saying (not to them )yet but to me she doesn't like them and how dare they use our things without asking and then she adds that she will do something similar to them? Has any one else experienced this random behaviour and if so how to diffuse the situation???
