My mother has dementia. It isn't severe. They come and go, the bouts. But she has it. And we know that the possibility it ends in Alzheimer's disease is distinct.

When I saw this video, I was reminded of how my mother has NEVER forgotten those good old southern gospel hymns she learned in church.

She knows all the words to every one of them and still sings them to herself.

This lady and her son have always had a family favorite. And despite the fact that she suffers from Alzheimer's disease, she can still play and sing the song without incident.

This is wonderful stuff.
