My grandad has been getting gradually more confused over the last year or so. More recently he has been having what I can only describe as mood swings and being verbally abusive to my Nanna and other family for no obvious reason. He is still driving but has been driving to the wrong places and when we tell him we are going the wrong way he gets very agitated and says that we said we wanted to go to the place he is driving too. As well as telling the same stories over and over again, he obsesses about money and thinks we are trying to strip him of his assests, which obviously we are not. We have approached him gently and asked him to see the GP but he is refusing as he doesn't think anything is wrong with him. I am very worried and distressed that something bad is going to happen soon of we don't take action. I would be so grateful if anyone could give any advise about what I can do next? Thank you
