title: Understanding the neurobiology of fear conditioning and emergence of posttraumatic stress disorder psychobiology: commentary on Blanchard et al.
abstract: In this article, we discuss the historical evolution of posttraumatic stress disorder (PTSD) after the Vietnam War, with a focus on an article by Blanchard, Kolb, Prins, Gates, and McCoy (J Nerv Ment Dis 179:371-373, 1991) published in this Journal in 1991 entitled Changes in Plasma Norepinephrine to Combat-Related Stimuli Among Vietnam Veterans With Posttraumatic Stress Disorder. In this commentary, we discuss the significance of this brief article and the developments in the PTSD field before, during, and after the Blanchard publication. Within this context, we discuss the eventual recognition in both the clinical and scientific fields that PTSD had a major neurobiological foundation. Finally, we examine the key implication of these discoveries from an epidemiological, a clinical, and a public health perspective.
