Article: "What If We're Wrong About Depression?"

Anna North, "What If We're Wrong About Depression?" The New York Times, November 26, 2014.

North examines two new lines of thinking about depression in medical research, one that considers the possibility that depression is related to infectious disease, and one that considers depression from the point of view of evolutionary psychology.  Both ideas are leading to innovations in diagnosis and potential treatment.  And both are leading to a consideration that what we've been calling by the same name - Major Depressive Disorder - may not be one disease at all, but may in actuality be different illnesses with many different causes.
