Experienced journalist Sebastian Junger writes about the complexities and dangers of PTSD in this new Vanity Fair piece. It's a long read, but well worth the time. Junger looks at the history of PTSD over the 20th century, its broader evolutionary history, and attempts to identify, manage and treat it today. PTSD is one of those disorders that spans disciplines - everyone from neuroscientists to anthropologist say something to say about it. Ideally, this diversity will foster solutions that might rely on biomedical science and cultural and psychological advances. PTSD gets at the core of what it means to be human in this modern age.
