The mind has been known to hide away the details and memories of traumatic event, only to send them back at unexpected times and places, sometimes after years have passed triggered by some sound, sight, smell or even feeling. The mind can play tricks in a way that makes the recall just as disturbing as the original event. The name for this mind monster is Post Traumatic Stress Disorder (PTSD). (Corales) Certain advancements in nuclear medicine are helping make progress in the treatment of the Post Traumatic Stress Disorder examples of the advancement are Neuroimaging, Cognitive behavioral therapy (CBT), Positron emission tomography (PET).
In years of studies advances in neuroimaging has been better understood the studies of neurophysiology of post traumatic stress disorder (PTSD), studies have shown dysfunction and volume changes of the medial prefrontal cortex and hippocampus many changes in the regional cerebral blood flow (rCBF). Findings has shown that regional cerebral blood flow of survivors of individuals suffering from PTSD differed significantly from healthy individuals. Findings have shown and support the assumption that severe psychological trauma may cause neurobiologic alterations that may contribute after years of the original trauma to a number of psychiatric symptoms commonly known as patients suffering from PTSD.

Trauma effects dimensions of behavioral functioning and psychological responses to physical and psychological injuries. The mind can recall traumatic events that impact such as emotional horror at witnessing a killing or a brutal death. That's when neurohormones are released and activates the fight or flight readiness. It could be the simple sound of a car back firing or a door slamming that can effect a soldier that suffers from post traumatic stress disorder, when a sound triggers that certain event it can change a person's attitude right then and there.
