Abstract:
The neurobiological knowledge on the potentially new diagnostic entity "posttraumatic stress disorder with secondary psychotic features" (PTSD-SP) is reviewed. Studies published between 1980 and 2006 were traced focussing on adult patients suffering from this "syndrome". Studies on cortisol, corticotrophin releasing hormone, dopamine beta-hydroxylase, smooth pursuit eye movements and psychopharmacology are described and potential pathophysiological mechanisms briefly discussed. More research is needed to validate the nosological status of PTSD-SP in order to promote neurobiological research and adequate therapeutic interventions.
