My Mum has Lewy Body and was diagnosed 3 years ago at the age of 63.She is becoming more confused but this fluctuates greatly.The most upseting thing for everyone,including Mum,is that she believes my Dad is two different people.She thinks they both look the same and have the same name.She gets very upset/agitated because she thinks this other person is reading their mail,living in their house,driving their car etc.This happens at some point every day now and can last a long time. We wondered if anyone could give us any advice on how to handle this especially when Dad is on his own.Anti-psychcotic drugs are not really an option because of the Lewy Body.We feel totally helpless and feel we have tried everything to reassure her but with no success.It is terrible seeing her like this but we don't know how to help her or my Dad.
