About this study
This study is a parallel arm, double-blind, randomized, controlled clinical trial to assess the safety and efficacy of an experimental software program designed to improve cognitive functions versus a computer-based software control. Both the study and the software being investigated meet the criteria of Non-Significant Risk.

| Study group | Role | What they receive |
|---|---|---|
| Experimental Treatment | Experimental | Computerized plasticity-based adaptive cognitive training and mindfulness training requiring a total maximum of 60 treatment sessions, up to 5 sessions per week, 40 minutes per session. Receives: Other: Computerized Plasticity-Based Adaptive Cognitive Training; Other: Mindfulness Training |
| Active Comparator | Active comparator | Commercially available computerized training and traumatic brain injury information session requiring a total maximum of 60 treatment sessions, up to 5 sessions per week, 40 minutes per session. Receives: Other: Commercially available computerized training; Other: Traumatic Brain Injury Information Session |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in performance on global cognitive composite score
Change in performance on global cognitive composite score based on the average of all normalized assessment measures.
Measured: At 3 months and at 6 months
Secondary outcomes (8)
Changes in performance on processing speed composite score
Change in performance on processing speed will be measured using the composite score created by averaging the z-scores of Pattern Comparison, Letter Comparison, and Digit Symbol Coding tasks.
Measured: At 3 months and at 6 months
Changes in performance on memory composite score
Change in performance on memory will be measured using the composite score created by averaging the z-scores of N-Back task, Spatial Working Memory task, WAIS-IV Digit Span and Rey Auditory Verbal Learning Test (RAVLT).
Measured: At 3 months and at 6 months
Changes in performance on executive function composite score
Change in performance on executive function will be measured using the composite score created by averaging the z-scores for the Trail Making, Flanker, and Stroop tasks.
Measured: At 3 months and at 6 months
Change in functional performance
Between-group magnitude of change in sum time of all tasks in the Timed Instrumental Activities of Daily Living (TIADL). Higher scores indicate greater impairment in functional performance.
Measured: At 3 months and at 6 months
Change in TBI functional status
Between-group magnitude of change in overall T-score using the self-report measure, Mayo-Portland Adaptability Inventory (MPAI-4). The overall T-score range is -38 to 106. Higher scores indicate more severe TBI functional status.
Measured: At 3 months and at 6 months
Changes in brain function
Change in resting state functional connectivity will be measured by 12-minutes of resting state functional MRI. Participants will be instructed to keep their eyes open and maintain attention on a white fixation cross on a black screen.
Measured: At 3 months
Changes in brain structure
Structural brain integrity will be measured with a high resolution 3D T1-weighted scan with good gray/white matter contrast and a complementary high-resolution T2-weighted anatomical scan.
Measured: At 3 months
Changes in task-related brain activation
Change in functional connectivity and brain activation will be measured while performing N-Back Task.
Measured: At 3 months
