A study using functional magnetic resonance imaging looked at the brains of 30 children, and concluded that blood flow and oxygenation differed for those with PTSD symptoms (n=16) compared to non-traumatized children (n=14). "Now we can see some real neurological reasons for the impulsivity, agitation, hyper-vigilance and avoidance behaviors that children with untreated PTSD often exhibit," said the study's author, Dr. Victor Carrion, Stanford School of Medicine.
