Brief Summary
The study will provide evidence on the long term outcomes of mTBI in service members returning from Afghanistan and Iraq. In addition, the study will provide evidence on mTBI incidence, and symptom patterns. Self-reported assessments at baseline and follow-ups will be combined with data on health care utilization and military job performance. The work, symptoms, and family interaction outcomes of returning soldiers screening positive for mTBI, combined mTBI and PTSD, and soldier controls will be compared at 3 months, 6 months, and at one year. The assessments over time will permit descriptions of symptom changes for these populations. It is likely the study will find similar findings to those of previous civilian studies - that concussive symptoms often resolve within months of injury. However, some soldier subsets may have chronic problems. Determining the incidence and outcomes of individuals with mTBI will assist medical providers in determining the types of follow-ups needed by returning service members and suggest the development of additional treatment interventions. These results may also inform treatment of civilian populations with mTBI. The three primary hypotheses are:
- 1.Concussive symptoms at the time of return from serving in Afghanistan and Iraq and symptoms persisting 3 months, 6 months, and 12 months after return will be associated with extent of exposure to combat, injury mechanism, associated injuries (co-occuring injuries), PTSD and other psychiatric co-morbidities, and number of deployment-related mTBIs.
- 2.Returning troops reporting concussive symptoms at the time of return from deployment will have more work related problems at each follow-up (including lower rates of return to duty, return to work, and poor quality of work).
- 3.The mTBI screening tool will be sensitive and specific to mTBI when compared to the criterion measure, which is a structured interview conducted by clinicians blinded to the screening results.

Outcome Measures
Primary Outcomes (2)
Over time change in Concussive symptoms
Concussive symptoms are measured with 3 instruments: Neurobehavioral Symptom Inventory; Patient Health Questionnaire; Headache Questionnaire.
Baseline; 3 months; 6 months; 12 months
Change in Work Related Issues
Measures of rates of return to duty; rates of return to work; and military job performance (for subjects remaining in military at follow-up).
3 months; 6 months; 12 months
Secondary Outcomes (4)
Automated Neuropsychological Assessment Metrics (ANAM)
Pre-deployment testing; and upon return from deployment
Change in Social Interaction
Baseline; 3 months; 6 months; 12 months
Alcohol and caffeine use
Baseline; 3 months; 6 months; 12 months
Health Utilization
Baseline; 3 months; 6 months; 12 months follow-up
Study Arms (2)
TBI while Deployed
Active duty service members returning from Afghanistan or Iraq who were screened positive for Mild TBI
No TBI while Deployed
Active duty service members returning from Afghanistan or Iraq who screened negative for mild TBI.
