Randomized Controlled Trial
The impact of alcohol dependence and posttraumatic stress disorder on cold pressor task response.
Posttraumatic stress disorder (PTSD) is commonly comorbid with alcohol-use disorders. Abnormalities in the hypothalamic-pituitary-adrenal (HPA) axis response are common in both disorders. The objective of this study was to investigate HPA axis reactivity to the cold pressor task (CPT) among individuals with alcohol dependence, PTSD, and comorbid alcohol dependence and PTSD. ⋯ There were differences in the HPA axis and subjective response to the CPT between the control group and both the alcohol and PTSD groups. The HPA response in the comorbid alcohol-PTSD group was not significantly different than that of the alcohol-only or PTSD-only groups.
