I am really hoping for some advice. I think that my dad may have the beginnings of Alzheimer's, although to be fair apart from googling symptoms I don't really know. My mum and dad are still together and in some respects I feel she is either protecting us/colluding/in denial. He has displayed word finding difficulties, forgets people he ought to know, will become silent in conversations and then add random stuff in to conversations which came from nowhere. He is also quite aggressive in his manner and everything seems to be a conspiracy theory. My mum says that she can't get him down to the doctor and I am desperately worried. What can I actually do in order to support this?
