Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Assessment and Training Assessments: The potential effects of remotely administered training will be assessed using neuropsychological tests of complex attention, executive function and memory, a test of functioning in challenging real world situations involving multitasking and goal management, and questionnaires assessing cognitive and emotional functioning in personal life.
Neurocognitive testing and functional evaluation sessions take 2- 3 hours each, or about 5 hours combined. The subject is free to take breaks throughout testing sessions, which will take place over one or two days. Subjects participate in assessments up to four times (Baseline, after 6-8 weeks; 12-16 weeks; and at 18-24 weeks), or up to 20 hours (5 hours x 4 time points). The investigators anticipate about 30 subjects will participate in assessments and training.
Experimental Intervention I: The Pathfinder training protocol will include supervised attentional regulation training sessions, either in-person or via the VA's video tele-health (VTEL) system, and home play of a computer game. Trainers will also call subjects between each supervised session to (i) check that patients are initiating home play (and help problem-solve or provide motivation, if necessary), and (ii) encourage transfer and generalization of learning, as per protocol. Home play will be configured to allow for about 35 minutes of play each day between supervised sessions. After the end of home game play, some additional time will be allowed for continued practice and application of trained skills in personal life.
Experimental Intervention II: Brain Health Education will consist of training sessions, either in-person or via the VA's video tele-health (VTEL) system, and home play of a computer game. The Brain Health Education protocol will be based on a curriculum already developed, designed to facilitate learning of TBI-relevant information. Trainers will also call subjects between each supervised session to (i) check that patients are initiating home play (and help problem-solve or provide motivation, if necessary). Home play will be configured to allow for about 35 minutes of play each day between supervised sessions. After the end of home game play, some additional time will be allowed for continued practice and review of TBI-relevant information.
Subjects will participate in either one or both experimental interventions, which are matched for time commitment. Participation in interventions will include weekly in-person or remote 1-2 hour sessions with a trainer over a period of 6-16 weeks. In addition to weekly training sessions, study activities will include about 15 minutes of weekly telephone contact with the trainer and about 35 minutes a day of playing a computerized game at home during the same period. Therefore, total training time range is approximately 43-93 hours, depending on whether participation includes one or both interventions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Neural Pathfinder Training
Neural Pathfinder training (PATH) will involve 6-8 weeks of training sessions with a trainer (1-2 hour sessions, average of 1 session per week), up to 3 hours of telephone contact with the trainer (about 15 minutes per week), and approximately 20 hours of home practice). Some subjects will only receive the PATH intervention.
Neural Pathfinder Training
Neural Pathfinder Training consists of game-based computerized training tools that target goal-directed attention regulation. Training will involve 6-8 weeks of 1-2 hour in-person or remote sessions with a trainer involving an average of one session per week; about 15 minutes a week of telephone contacts with the trainer; and approximately 20 hours of homework (35 minutes/5 days a week), consisting of short attentional regulation practice and computer-assisted cognitive training game play.
Brain Health Education
Brain Health Education (EDU) will involve 6-8 weeks of training sessions with a trainer (1-2 hour sessions, average of 1 session per week), up to 3 hours of telephone contact with the trainer (about 15 minutes per week), and approximately 20 hours of home practice). Some subjects will only receive the EDU intervention. Some subjects will receive both the PATH and EDU interventions.
Brain Health Education
Brain Health Education (EDU) will involve 6-8 weeks of 1-2 hour in-person or remote sessions covering brain anatomy and health with a trainer involving an average of one session per week; about 15 minutes a week of telephone contacts with the trainer; and approximately 20 hours of homework (35 minutes/5 days a week), consisting of computer game play involving decision-making and motor skills.
