Hey, dan! Welcome to the site!
I give ya credit with your job. Does the guy have any previous hobbies? What kind of sports did he watch/participate in? Look up the teams during his younger years, and ask him about those years and how he felt. What did he do for a living? I have heard about an 'interview process', where someone 'interviews' the person on Hospice/with Alzheimer's about their life 'before the change'. It involves major things in the person's life, ie: WW2, Korea, 'The Bomb', marriage/school/work, etc. When I come across the paperwork, I can fill you in more.
Keep us posted on things!
Any other ideas?
PS...I try to drop in the chatroom every so often; my work schedule is a bit wild, but.....if anyone else drops in and I am around, I pop in.
