Welcome, Bill. I haven't been a member long but have found this to be an informative, friendly and helpful group. I don't know enough to help with your first concern, but addressing your second concern, I would think keeping everything in the open is the best way to go. I'm close to your father's age and I'm always happy (even flattered sometimes) when my children keep me in the "loop" of events. Since PD may be genetically transferred, one approach for you and your brother could be to learn all you can about PD for your OWN good and information; that would certainly keep your father from being viewed as the victim. Do everything you can to keep him interested and active, and showing your own interest is one of the best ways to do this. The biggest problem with my mother (she is 80) is that she has stopped doing things (taking trips with her peers, going to church, etc.) that she enjoyed before she found out she has PD. Good luck and take care, Yatta Jacob ([log in to unmask])
