- 1. Classified as an anxiety disorder. After trauma exposes the victim to actual or threatened death or serious injury, 3 dimensions of PTSD unfold: (1) reexperiencing the event with distressing recollections, dreams, flashbacks, and/or psychologic and physical distress; (2) persistent avoidance of stimuli that might invite memories or experiences of the trauma; and (3) increased arousal (Vieweg et al, 2006) Post traumatic stress disorder 1

Research into the pathophysiology of PTSD has focussed on areas of the brain associated with fear processing and memory: - Amygdala, Hippocampus, Medial prefrontal cortex There is still uncertainty over the patho- physiology of PTSD. Hypothesised that PTSD represents a failure of the prefrontal-anterior networks to regulate the amygdala resulting in hyper-reactivity to threat. Pathophysiology of PTSD 3
