The New York Times writes about an exhibition of self-portraits by an artist with Alzheimer's:

When he learned in 1995 that he had Alzheimer’s disease, William Utermohlen, an American artist in London, responded in characteristic fashion.

"From that moment on, he began to try to understand it by painting himself," said his wife, Patricia Utermohlen, a professor of art history.

Nine of the portraits are collected in a chronological slideshow on the NYT's site, and they are heartbreaking.

(If this doesn't make you want to vote for Ben Cardin, I don't know what will.)
