Read our Post Traumatic Stress Disorder research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This research is testing a new approach called Very Brief Exposure (VBE) that may help combat veterans with PTSD. Instead of asking you to directly confront traumatic memories—which can feel overwhelming—VBE shows combat-related images for just 17 milliseconds (too fast for your conscious mind to fully register) followed by a masking image. The study uses brain imaging to see whether this gentler approach can reduce fear responses without causing the emotional distress that often leads people to quit traditional PTSD therapy.
Current treatments for combat-related PTSD work, but many veterans find them so emotionally difficult that they drop out of therapy. This trial exists to develop a new treatment that reduces trauma-related fear and brain activity while being less emotionally overwhelming, so more veterans will stick with and benefit from therapy.

You would come in for a brain imaging scan (fMRI), during which you'll view three types of image sequences while lying in the scanner. Some images will be combat-related scenes shown very briefly (too fast to consciously see), some will be everyday scenes shown very briefly, and some will be visible combat images. The entire session involves viewing these images while researchers measure your brain activity. The study aims to understand how your brain responds to each type of exposure and help develop a less distressing form of PTSD therapy.
