Better injured than stressed ?

Nature Neuroscience Nat Neurosci. 2008 Feb;11(2):232-7. Epub 2007 Dec 23 

Nature Neuroscience published an article in its current issue (in February 2008) about post-traumatic stress disorder (PTSD). Post traumatic stress disorder has been associated with hypoactivity in the ventromedial prefrontal cortex (vmPFC), hyperactivity in the amygdala and reduced volume in the hippocampus. Dr Koenigs et al studied a subgroup of veterans from the Vietnam Head Injury Study that experienced PTSD and also suffered a focal injury in ventromedial prefrontal cortex (vmPFC) or anterior temporal area that included the amygdala. They found a significant reduction in PTSD incidence in this population implying an association with the brain areas mentioned.

So one could wonder: what is the most dreadful one ?   

To live and repeatedly suffer with the memories of war everyday ?

Maybe the answer is… to sustain a focal brain injury and a possible concussion for a few days. The sure thing is that you should forget something…
