One of the most pressing concerns within the VA currently is the provision of interventions that address the cognitive as well as emotional problems faced by Veterans with mild TBI and comorbid conditions. When completed, these studies will inform us whether training core attentional self-regulatory control functions via personally-relevant activities will be effective in improving daily life for Veterans with mild TBI and comorbid conditions. The study design will provide a test not only of potential benefits for real life functioning, but also determine to what extent these benefits are related to actual changes in cognitive/behavioral performance and brain networks corresponding to these functions. This project will provide a foundation for future studies to investigate the neural mechanisms that support improvements of cognition and behavior in mTBI.
