He is still driving. Still has guns. Still handles all the decisions for himself and his wife. We have noticed judgement problems, paranoia, depression and other issues, but beyond a few isolated incidents, he doesn't seem to be too forgetful or getting lost. His wife is older than he is and very frail, so her son wants to start being responsible for her care. Step dad is very resistant and will not allow it. I know he is eventually going to become very ill, but at this point he is still very active. How long before he needs full time care? We are trying to plan without any imput from him - he is still in denial. We know we have to get ready for this, but have no contact with the doctors since we are not blood relatives. His wife, my fiance's mom, is deaf and also in denial about the situation. She has no idea what she has ahead of her and we have to get her ready. How long do we have?
