I have worked on my cards over the last few days, and know several people on my card list are in an early-mid stage of dementia.
My mom is in late stage dementia and in 24/7 care now. Christmas, like everything else, is totally irrelevant to her now. Last year she tried to throw all of her gifts in the trash, saying those didn't belong to her.
One thing that really bothered me is how quick people were to write mom off their lists as she declined. When she stopped going to church and could no longer be helpful there, she was forgotten. No birthday cards, no Christmas cards, nothing. Up until we moved her out of the house, Mom was going to her mailbox every day; any piece of mail with her name on it was hers! She carried the few cards she received last Christmas around with her and placed them by her bed at night. I wrote notes to those who sent her a card so they would know what their simple effort had meant to my mother.
Moms dementia journey has heightened my awareness and I will do what I can to try to make someone smile and add a ray of light to the darkness of dementia.
