If Father Christmas Forgot...

This Christmas advert from Alzheimer's Research UK is a very touching - and thought-provoking - vision of what was to happen if Santa got dementia. 

While the concept might seem a little trite, the effect of the advert is considerable, not least as they consider the ways dementia might changed the beloved emblem of Christmas. 

A sobering - and much-needed - Christmas message. Share it with everyone.
