Mary. I'm currently reading Oliver Sacks' book, AN ANTHROPOLOGIST ON MARS, a very interesting account of the case histories of seven neurological patients. I believe it's his latest book and is available in premium softcover. Given all that we have learned about neurology and the complexity of the brain from having PD (or being a caretaker for a PWP), I would think everyone on the list would enjoy Sack's books. Along with the books you mentioned, he has written SEEING VOICES: A JOURNEY INTO THE WORLD OF THE DEAF and MIGRAINE. Mary Sheehan
