Objective: Many studies reported deficits in cognitive functions in post-traumatic stress disorder ( PTSD). Most were, however, conducted on man-made trauma survivors. The high comorbidity of alcohol use and depression with PTSD in these studies further complicated the interpretation of their results. We compared prefrontal lobe functions and memory in three earthquake survivor groups: current PTSD, past PTSD and no PTSD. We hypothesized that prefrontal performances of the current and past PTSD groups would be worse than that of control group. Method: Survivors of the 1999 earthquakes in Turkey were evaluated for current and lifetime PTSD. Memory and prefrontal functions were assessed by a neuropsychological test battery.
