Susannah Cahalan offers some gripping and insightful health autojournalism here. This was one of the better patient narratives of a mysterious and sudden-onset condition that I can remember reading (still with some pitfalls of the genre, especially around discussing cognitive and behavioral symptoms within somewhat traditional, saneist paradigms). But overall it felt really careful, tightly written, and emotionally reflective. I ended up giving my copy to a premed friend to read next.
