Susannah Cahalan has a month-long gap in her memory from when she was struck by the little known disease anti-NMDA receptor encephalitis. Cahalan, a New York Post journalist, wrote an account of her ordeal shortly after it happened, and went on the Today Show to talk about it. Now she has written a book on her experience called Brain on Fire and wants to make people aware of the disease, and that was the subject of a follow-up segment on the Today Show. She is not the only person to have been afflicted. There is more information about the disease and the book on Cahalan's website. She was interviewed at length on NPR's Fresh Air earlier this month. Novelist and essayist Leslie Jamison has a well-written review of Brain on Fire and puts it in its literary context.
