You need to access the ADNI DOD study data. From the top menu once you are logged in, Projects --> ADNIDOD. Then Download --> Study Data --> click on Central SFVAMC Eligibility (VAELG.csv). Use the Cohort variable and the Data Dictionary (also on Study Data) page to identify the SCRNOs associated with TBI. Then you can enter those SCRNOs separated by commas in Search --> Advanced Image Search --> Subject IDs

TBI patients were not included in ADNI study as history of significant head trauma followed by persistent neurologic defaults or known structural brain abnormalities is part of the exclusion criteria for all subjects.
