Clinical trials

The goal of the RAMP mind-body program is to provide Veterans with information and tools that can help them manage their pain. The program explores the important connection between our bodies and minds, and how to use this special connection to manage pain more effectively.

The goal of this clinical trial is to learn if combining brain stimulation with cognitive training can improve thinking skills in older adults who have had a traumatic brain injury (TBI). The main questions are: * Does transcranial direct current stimulation (tDCS) make cognitive training more effective for improving attention, memory, and decision-making? * Is this type of home-based program feasible and acceptable for older adults with TBI? Researchers will compare two groups: one group will receive active tDCS during cognitive training, and the other group will receive sham (placebo) tDCS during cognitive training. Participants will: * Complete computer-based cognitive training exercises (BrainHQ) to practice attention, memory, and decision-making. * Receive either active or sham tDCS during training sessions. * Complete assessments before and after the program to measure changes in thinking and daily functioning.

The goal of this clinical trial is to examine the use of sedative ketamine to treat depression and post-traumatic stress disorder (PTSD) in Veterans with mild to moderate traumatic brain injury (TBI). The main questions it aims to answer are: * Efficacy of ketamine to reduce symptoms of depression and/or PTSD * Safety of ketamine to treat depression and/or PTSD in TBI Participants will be randomly assigned to receive either ketamine or midazolam (active placebo) twice a week for 3 weeks. During participation, subjects will be interviewed, have lab tests, and complete rating scales, and questionnaires.
