Combined Neuromodulation and Cognitive Training for Post-mTBI Depression

Summary

The primary goal of this clinical trial is to evaluate whether Personalized Augmented Cognitive Training (PACT) plus intermittent theta burst stimulation (iTBS) is effective for treating depression in Service Members, Veterans, and civilians who have sustained a mild TBI. Participants will receive PACT plus 20 sessions of iTBS or sham iTBS over 4 weeks. Assessments will occur at baseline, 2 weeks, 4 weeks, and 8 weeks. Researchers will compare the PACT+iTBS group to the PACT+sham iTBS group to see if PACT+iTBS is associated with more depression improvement.
