Photographing Alzheimer's

There is a beautiful and moving (in both sense of the word) gallery of photographs of the surgeon Ed Akell, taken by his wife Judith Fox, since his diagnosis with Alzheimer's twelve years ago. These are emotive portraits and really tell a story -- testimony to the power that still photography retains. The photographs are on display at the Cork Street Gallery in London this weekend. But the slideshow on the BBC with a commentary by Judith Fox is a good substitute if you can't make it.
