title: [Comorbidity of posttraumatic stress disorder and mild closed head injury in war veterans: endocrinological and psychological profiles].
abstract: OBJECTIVE
  To determine the degree of psychological and endocrinological changes in war veterans with the diagnosis of Chronic Posttraumatic Stress Disorder (PTSD) regarding presence/absence of comorbid mild closed head injury (mCHI) caused by explosive devices.
  
  
  METHODS
  Two groups of PTSD inpatients, with (n = 37), and without (n = 86) sustained blast trauma followed by mCHI were formed during the psychiatric treatment. Participants were interviewed by experienced clinicians who used the PTSD Interview (PTSD-I). In addition, patients completed the Symptom Checklist-90-Revised (SCL-90-R). Serum levels of ten hormones were assessed: triiodothyronine, thyroxine, thyrotropin-stimulating hormone, prolactin, luteinizing hormone, follicle-stimulating hormone, and insulin, by radioimmunoassays and hydrocortisone, growth hormone and testosterone by fluoroimmunoassays.
  
  
  RESULTS
  Veterans with comorbid mCHI and PTSD showed significantly higher level of amnesia for traumatic event as well as of somatization on the SCL-90-R. Significant differences of hormone levels were not found.
  
  
  CONCLUSIONS
  The results didn't support the hypothesis on specific PTSD subgroup characterized by history of mCHI and consecutive postconcussion syndrome. The absence of differences in levels of hormones indicated the dominant role of psychogenic trauma in the etiology of hormone disbalance in chronic PTSD. Amnesia for traumatic event in war veterans with comorbid PTSD and mCHI was easily explained by neurogenic peritraumatic amnesia due to the blast trauma, but it did not affect either quality of intensity or posttraumatic symptoms as well as endocrinological parameters.
