Brief Summary
This project will study 40 Veterans identified with symptoms understood to characterize mild to moderate Traumatic Brain Injury (TBI) including Post Traumatic Stress Disorder (PTSD). Following screening and informed consent, Veterans will be randomly assigned to treatment with repetitive Transcranial Magnetic Stimulation (rTMS) or sham rTMS (placebo). Additional examinations will compare brain imaging (structural and functional MRI scans at rest) across participants at baseline, after acute rTMS treatment, and at 6 month followup. The VA population differs significantly from populations that have been included in prior trials of rTMS for many conditions such as depression, chronic pain, and PTSD. Many returning Operation Enduring Freedom (OEF)/Operation Iraqi Freedom (OIF) personnel and Veterans with concussion histories report cognitive problems, such as impaired attention, verbal fluency, poor planning, reduced working memory, and mental flexibility. The investigators hope to show the efficacy and durability of rTMS in treating these symptoms safely in Veterans with co-morbidities.

Outcome Measures
Primary Outcomes (1)
Trail Making Test Part B
The primary hypothesis is that Veterans receiving active rTMS will show improvement more than sham treated Veterans in performance between baseline and last assessment of \>1 SD on the Trail Making Test part B. This test is known for its accurate assessment of executive function in mild and moderate TBI. The TMT is a timed test and the goal is to complete the test as accurately and as quickly as possible. Raw scores are reported in seconds to complete the test. For Part B, an average score is 75 seconds and a deficient score is greater than 273 seconds. The present study reports T-scores, which can range from a minimum of 0 and a maximum of 100. The higher the T- score achieved by a participant, the better the performance, indicating a higher level of functioning.
Baseline (up to two weeks after screening visit); Post-Treatment (2 weeks from end of Baseline up to one month from entering the study but always the day of last treatment)
Secondary Outcomes (5)
Sustained Improvement on Executive Function
6-month post treatment follow up
Change in Quality of Life (QOL) Scale
baseline and immediately post treatment (~two weeks)
Moderators of Response: PTSD Score
Baseline only
Treatment Induced Change in Functional Connectivity
post treatment (2 weeks) and 6-months
Change in a Mediator of Response: Brain Derived Neurotrophic Factor (BDNF)
baseline and post treatment (2 weeks)
Study Arms (2)
ACTIVE rTMS
EXPERIMENTALThose receiving experimental treatment will receive 20 sessions of rTMS. The treatment will be delivered by trained medical personnel.
Sham rTMS
PLACEBO COMPARATORThose receiving the sham rTMS will receive 20 sessions of sham rTMS. The treatment will be delivered by trained medical personnel.
