Hi Andy; How do you relate to those people who seek deeper meaning? Do you stick to your research results and present "just the facts" or do you try to facilitate some kind of dialog, which might help the concerned parties gain some measure of solace. Having gone through something similar with both parents I know what it feels like to deal with people one loves, whom one once depended on completely for sustenance, who's capacity for interacting in even the most basic ways has been so severely degraded. I'm not sure what you can tell someone like that except maybe...."they know that you love and care about them; they appreciate and enjoy your visits; your presence is of great comfort to ____, I can assure you".
