Dear Experts (With regard to diagnostic assignments in ADNIDOD): The selector for subject-specific information still appears to be inoperative, so I have been using VAELG.csv to assign diagnotic group status. In the datadic, the code for FLDNAME "COHORT"
indicates that 1=PTSD; 2=TBI; 3=Normal Control;4=PTSD & TBI. In the Comments field, I see the repeated use of the term "dirty TBI" for Group 4. The original protocol only indicated that there would be three groups (NL/TBI/PTSD). Is there a memorandum
introducing this cohort? Are we to assume that Group 4 (PTSD & TBI) should counted as primarily TBI subjects with the caveat of mixed pathology?
Thank you for your interest in this proejct.
The subjects with PTSD and TBI are TBI subjects who have PTSD, or symptoms strongly suggestive of PTSD
