rTMS to Improve Cognitive Function in TBI
Completed · Not applicable · Has a placebo group
Conditions studied: Traumatic Brain Injury
In brief
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.
