Took care of my dear MIL for years while I watched her decend into oblivion. Eventually had to put her in a care facility. We were very close and I loved her like a sister. My word for family and friends, do not leave it all up to one person to take care of a Alz. person. Kick in and help, let them know you are there to give them a break. It can wear one down if they feel like they are rowing that boat all alone. She has gone on now and I never regret a minute with her even when she couldn't remember who the heck I was. The only thing I do regret is that I made her a quilt and after she was gone, was gathering up her possessions at the care facility and someone had stolen the quilt that was to go on to her daughter.
