Abstract

Background:Post-traumatic stress disorder is characterized by intrusive traumatic memories. Presently, a controversial debate is ongoing regarding whether reduced cortisol secretion in post-traumatic stress disorder promotes an automatic retrieval of trauma-associated memories. Hence, a pharmacological elevation of cortisol was proposed to decrease post-traumatic stress disorder symptoms, particularly intrusions. The present study investigated the impact of two different doses of hydrocortisone on automatic memory retrieval using a randomized, double-blind, placebo-controlled, crossover study in 30 inpatients with post-traumatic stress disorder.Methods:All participants were female and received various psychotropic medications. They were randomly assigned to one of two groups within a crossover design: they received either 1 week placebo followed by 1 week hydrocortisone 10/d, followed by 1 week placebo, followed by hydrocortisone 30 mg/d (15 participants) or 1 week hydrocortisone 30 mg/d, followed by 1 week placebo, followed by 1 week hydrocortisone 10 mg/d, followed by 1 week placebo (15 participants). The outcome measures were the frequency and the intensity of intrusions, the overall symptomatology of post-traumatic stress disorder and the general psychopathology.Results:We did not find any differences in the frequency and the intensity of post-traumatic stress disorder-related intrusions between the 10 mg hydrocortisone, the 30 mg hydrocortisone and the placebo condition. All effect sizes for the hydrocortisone condition vs. placebo were very small. Additionally, the overall symptomatology of post-traumatic stress disorder and the general psychopathology did not differ between the hydrocortisone therapies and placebo.Conclusions:Our results do not show any effect of the hydrocortisone administration on intrusions in complex post-traumatic stress disorder.
