Author: Ewing-Cobbs, et al. (2017), Psychoneuroendocrinology

Research Article Highlights;

  • HPA and ANS stress systems were dysregulated after nonintentional pediatric injury.
  • HPA and ANS activity and regulation varied with age at injury and type of injury.
  • Cortisol reactivity to social stress was attenuated after brain or body injury.
  • After brain injury, cortisol elevated in children, sAA elevated in adolescents.
  • sAA, but not salivary cortisol, predicted specific post-traumatic stress symptoms.
