Alzheimers in heaven.

[Gawdzilla Sama]

Family members are more often much better than 'the professionals'.
When someone has dementia it can be better for them to see a familiar face.
Apart from that, I know no details and I'm sure you have your reasons for feeling that way.

If you were responding to me may I say that I'm meant support groups of people in similar situations, not homecare professionals or the like. They have their own coping mechanisms. Most ordinary people enter the situation largely clueless. I know I did.
