Official title

Psychophysiology of Prolonged Exposure for PTSD With/Without Yohimbine

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The proposed study has three distinct but related research objectives. The first goal is to measure physiological correlates of successful treatment with Prolonged Exposure (PE) therapy for posttraumatic stress disorder (PTSD) in veterans of the Iraq and Afghanistan wars. Individuals with PTSD often experience elevated heart rates and other objectively measurable signs of anxiety when confronted with safe situations that remind them of past dangerous situations. We will measure physiological responses and compare the outcomes to patient's self reported subjective accounts of symptom improvement on traditional measures of PTSD. Developing a way to measure objective gains in symptoms improvement may help researchers who are studying ways to improve PTSD treatment. The second goal of the study is to investigate if yohimbine, a drug found to promote a specific type of learning, will improve treatment outcomes for veterans in PTSD treatment. The third goal is to investigate if ability to get used to loud startling audio tones correlates to baseline PTSD pathology and treatment outcomes for PE. This goal represents an important step forward in understanding characteristics of heritable traits that are related PTSD. It is significant because such research may one day lead to the development of individual responder policies that will assist patients by individualizing treatment plans based on personal characteristics.
