Conditions
Alzheimer Dementia
Posttraumatic Stress Disorder
Traumatic Brain Injury
Registration Number
NCT03641768
Lead Sponsor
Duke University
Brief Summary

The purpose of this study is to learn about how trauma, posttraumatic stress disorder (PTSD), and mild traumatic brain injury that can occur during deployment affect the brain. The investigators also want to learn how PTSD and mild traumatic brain injury can affect the chance of developing Alzheimer disease later in life.
