One of the main changes in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was the separation of Stress Related Disorders from the Anxiety chapter. This separation paves the way to examine the unique characteristics of posttraumatic stress disorder (PTSD) (ie, identifiable onset, memory processes, etc) and related neural mechanisms. The time that elapses between the traumatic event and the manifestation of the disorder may also be addressed as the "golden hours," or the window of opportunity in which critical processes take place and relevant interventions may be administrated.
Keywords: Benzodiazepines; HPA axis; PTSD; golden hours; stress related disorders; window of opportunity.
