Abstract:

Posttraumatic stress disorder (PTSD) is associated with abnormal functioning of the hypothalamic- pituitary-adrenocortical (HPA) axis, as shown by alterations of cortisol levels. However, results on the link of cortisol level with PTSD are inconsistent. Recent studies imply that PTSD patients show temporal characteristics of the change in cortisol level with the elevation at early stage and thereafter the decrease relative to the normal basal cortisol level after traumatic exposure. The temporal characteristics might be disturbed or masked by some factors, such as characteristics of biomarker, course of PTSD, type and intensity of stressor and comorbid disease. The present review suggested that future research needs to further profile temporal characteristics of change in cortisol level among PTSD patients by controlling the influencing factors and utilizing long-term follow-up design in combination with acute-stress and chronic- stress biomarkers and investigate whether it can be used to predict and intervene PTSD through cortisol treatment. Considering that cortisol level is regulated by metabolism and antagonism procedures, the use of multi-biomarkers will facilitate the reliable evaluation of the HPA axis activity among PTSD patients.
