A fMRI Study of the Treatment of Danish Veterans With PTSD With Prolonged Exposure Therapy

August 9, 2016 updated by: Jørgen Aagaard, Aalborg University Hospital

A fMRI Study of the Treatment of Danish Veterans With Post-Traumatic Stress Disorder With Prolonged Exposure Therapy: Study Protocol for a Case-control Trial

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

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
60

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 35 years (Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Psychometric changes
Time Frame: Baseline - 3-6-12-36 months
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.
Baseline - 3-6-12-36 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Biomedical changes
Time Frame: Baseline - end of treatment - 36 months
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.
