Personalized, Augmented Cognitive Training (PACT) for Service Members and Veterans with a History of TBI

Mild traumatic brain injury (TBI) is a common medical condition that occurs when a head injury causes someone to lose consciousness, feel dazed or confused, or be unable to remember events occurring immediately after the injury. While most individuals with mild TBI recover within weeks or months, some individuals with mild TBI report chronic symptoms such as difficulty with cognitive skills like attention, learning, or memory, along with other symptoms such as irritability or headache. Previous studies, including those conducted by our scientific team, have shown that cognitive rehabilitation can help patients with persistent symptoms after mild TBI return to full duty, work, school, and other important life activities. Specifically, cognitive rehabilitation can provide lasting improvements in thinking abilities, functional capacity, post-concussive symptoms, and quality of life after mild TBI. However, effective interventions are still out of reach for many service members and Veterans with TBI. For patients who have returned to duty, employment, or education, scheduling up to 60 hours of treatment (a typical treatment schedule in many settings) may not be feasible. Additionally, some patients may live in areas where it is burdensome to make numerous visits to a medical center. Personalized Augmented Cognitive Training (PACT) compresses treatment into six hours of once-weekly personalized, one-on-one training by selecting treatment modules based on patient needs and priorities-substantially reducing the total amount of time required to complete treatment. PACT can be offered either in-person (in clinic) or via home-based video telemedicine, depending upon patients' preferences. Additionally, PACT includes training and encouragement for service members and Veterans to make self-directed use of mobile apps that train cognitive skills and strategies.The primary goal of this study is to evaluate whether PACT is effective at improving cognition, symptoms, and functional outcomes among military service members and Veterans with a history of mild TBI. The study will also yield information about factors that can enhance or interfere with treatment, such as number of previous TBIs, presence of post-traumatic stress; and choice of in-person vs. video telemedicine delivery of care.
