Captain,
Your friend's family is really in for some tough times with altzheimer's. They call it "the long goodbye" for a reason. We lost my BELOVED grandfather a year ago this past Christmas day (of all days). He had battled altzheimer's for about 5 years, and the last two and a half years were pretty grim. It tore my heart out to see him not recognize me. We had the very good fortune of growing up within walking distance to my grandparent's house, and my grandmother was our caregiver, as both of my parents worked full time. My parents also had VERY active social lives, and we kids spent the night at my grandparent's house constantly. I've always thought of my grandparents as my PARENTS! As my grandpa progressed with the disease, he didn't know any of us, yet every time Kylie came over, he got the bigget smile on his face, and loved to give her kisses. He didn't know her name, he would just say "that's my girl!" Well, Kylie happens to look like MY TWIN as a child, so we believe he may have thought Kylie was me.
The most important thing you can do is PRAY for your friend's family. Then offer help in any way you can. My grandma was very private when my grandpa was sick, so if they are also, respect that. But, my grandma cared for my grandpa 24/7 until the day he died, so we would come over whenever possible to stay with him and give my grandma some freedom to go shopping, get her hair done or whatever. I hated seeing grandpa sick, but I wouldn't trade the memories I have of helping care for him FOR ANYTHING. I helped feed him, shave him, dress him, and yes, even change his "diapers" WITH TOTAL LOVE! He cared for me and my brother and sister the same way all of our lives, and it was my pleasure to care for him in his old age. And my kids learned a valuable lesson too. They learned that elderly, sick & disabled people are still presious lives, and need to be treated with dignity. Kylie always tells me she will take care of me when I'm old.
Sorry if this post was a downer, but I do love talking about my grandpa!
