My father in law, who has the beginnings of dementia, apparently asked my mother in law, "Am I going crazy?", as his memory issues became apparent to him.

He's now been relieved of all financial duties. Our worry is that...he doesn't really have anything else to do. All he did was go through financial emails, and papers, and worry and think about them but...at least it gave him something to do.

One positive is that he could not be scammed anymore. He just couldn't follow their steps. (He has gotten scammed before).
