About

In this article, the investigators report the design and protocol of a functional magnetic resonance imaging study (fMRI) of the treatment of Danish veterans with PTSD with Prolonged Exposure Therapy (PE). In total 30 Danish veterans will be recruited, who meet the ICD-10 diagnostic criteria for PTSD, and treated with PE. A group of controls will be recruited consisting of age-appropriate same sex veterans who have participated in international missions similar to the patient group

Full description

Primary outcome measures are the changes in d2-test assessment of attention and concentration, Beck Depression Inventory, Post-traumatic Symptom Scale-Interview version and PTSD Checklist- Military Version.

Secondary outcome measures concern changes of Brain Derived Neurotrophic Factor (BNDF) and changes in the brain structure with focus on the hippocampal function using fMRI.

Enrollment: 60 estimated patients

Sex: All

Ages: 20 to 35 years old

Volunteers: Accepts Healthy Volunteers
