Pre-deployment prediction of partial and full PTSD in a French military cohort.
📄 Abstract
Post-traumatic stress disorder (PTSD), in its partial or full forms, is frequently observed in military populations. It is therefore important to predict the risk of PTSD prior to deployment. Since elevated allostatic load markers have been described in PTSD, we investigated whether these alterations pre-exist before PTSD onset. Our objective was to explore the ability of four allostatic load markers (urinary and blood cortisol, BDNF and 8-iso-PGF2α) to predict partial/full PTSD onset after a 6-month deployment. We conducted a prospective study in a French military cohort deployed to Afghanistan. PTSD was assessed before (M After controlling for age, pre-deployment PCLS scores, and the number of missions, we found that elevated M Asymptomatic subjects at risk of partial/full PTSD exhibit a common pattern of hypothalamic-pituitary axis dysregulation, similar to that observed in established PTSD.
