Salivary Cortisol and PTSD Symptoms in Persian Gulf War Combatants

Subjects with chronic posttraumatic stress disorder (PTSD) show a distinct profile of hypothalamic-pituitary-adrenocortical axis alterations characterized by diminished cortisol levels and stronger negative feedback inhibition.' So far, it is not clear if this endocrine regulation pattern represents a premorbid condition, an effect of trauma per se, or the consequence of former or ongoing PTSD symptoms. To address this issue, studies beginning closer to the traumatic event are needed. We examined the relationship between salivary cortisol concentrations and PTSD symptoms in Persian Gulf War combatants within 18 months of their homecoming.
