I think we all have some idea of what we think PTSD is, but it turns out PTSD isn't as clear-cut as I thought.
Apparently, when PTSD was first introduced into the DSM, the diagnostic criteria required a traumatic event "outside the range of usual human experience" that would cause "significant symptoms of distress in almost anyone." That fits pretty well with my own perception of PTSD. Rape, war, torture, violent experiences...these all fit into that description. PTSD is a normal response to an abnormal stressor.
