The symptomatology of PTSD.In PTSD a traumatic event is not remembered and relegated to one's past in the same way as other life events. Trauma continues to intrude with visual, auditory, and/or other somatic reality on the lives of its victims. Again and again they relieve the life-threatening experiences they suffered, reacting in mind and body as though such events were still occurring. PTSD is a complex psychobiological condition.
