My mum has Alzheimers & vascular dementia. She has occasionally been delusional (usually telling me a neighbour has been nasty to her) but the past couple of months the delusions are more frequent & nasty, leaving her either really angry or upset. Recently her delusions are mainly about me & our (imagined) arguments but now she's accusing my daughter of stealing money from her. Fortunately, she said it happened while she was out shopping & claimed my daughter walked over and snatched the notes from her then ran away - my mum hasn't done her own shopping for almost 2 years & can't go out alone. So far, we are able to disprove any claim she makes but I'm really worried about the nature of the delusions and if anyone happens to believe her claims. I've found so many answers here & had so much support in the past. Can anyone advise. Thanks.
