Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Mild Traumatic Brain Injury Other: Computerized Plasticity-Based Adaptive Cognitive Training Other: Commercially available computerized training Other: Mindfulness Training Other: Traumatic Brain Injury Information Session Not Applicable

Detailed Description:
The primary objective of this study is to evaluate the effects of combination of mindfulness training (MT) and adaptive cognitive training (CT) on the cognitive abilities, functional status and quality of life of soldiers and veterans diagnosed with traumatic brain injury (TBI, also referred to as a concussion, or blast exposure), as compared to a computer-based control.

Primary Outcome Measures :
  1. Changes in performance on global cognitive composite score [ Time Frame: At 3 months and at 6 months ]
    Change in performance on global cognitive composite score based on the average of all normalized assessment measures.


Secondary Outcome Measures :
  1. Changes in performance on processing speed composite score [ Time Frame: At 3 months and at 6 months ]
    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.

  2. Changes in performance on memory composite score [ Time Frame: At 3 months and at 6 months ]
    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).

  3. Changes in performance on executive function composite score [ Time Frame: At 3 months and at 6 months ]
    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.

  4. Change in functional performance [ Time Frame: At 3 months and at 6 months ]
    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.

  5. Change in TBI functional status [ Time Frame: At 3 months and at 6 months ]
    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.

  6. Changes in brain function [ Time Frame: At 3 months ]
    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.

  7. Changes in brain structure [ Time Frame: At 3 months ]
    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.

  8. Changes in task-related brain activation [ Time Frame: At 3 months ]
    Change in functional connectivity and brain activation will be measured while performing N-Back Task.


Other Outcome Measures:
  1. Change in Neurobehavioral Symptoms [ Time Frame: At 3 months and at 6 months ]
    Between-group magnitude of change in sum score using the self-report measure, Neurobehavioral Symptoms Index (NSI). The scoring range is 0-88. Higher scores indicate more severe neurobehavioral symptoms.

  2. Change in PTSD Symptoms [ Time Frame: At 3 months and at 6 months ]
    Between-group magnitude of change in sum score using the self-report measure, PTSD Checklist (PCL-5). The scoring range is 0-80. Higher scores indicate more severe PTSD symptoms

  3. Change in Depressive Symptoms [ Time Frame: At 3 months and at 6 months ]
    Between-group magnitude of change in sum score using the self-report measure, Beck Depression Inventory (BDI-II). The scoring range is 0-63. Higher scores indicate more severe depressive symptoms.

  4. Change in Health-Related Quality of Life [ Time Frame: At 3 months and at 6 months ]
    Between-group magnitude of change in sum score using the self-report measure, Quality of Life after Brain Injury (QOLIBRI). The scoring range is 0-100. Lower scores indicate lower quality of life.

  5. Change in Executive Function Symptoms [ Time Frame: At 3 months and at 6 months ]
    Between-group magnitude of change in After total T-score using the self-report measure, Frontal Systems Behavior Scale (FrSBe). Raw scores are converted to age- and education-corrected T-scores. The mean T-score is 50, scores greater than 65 are considered clinically significant.

  6. Change in Cognitive Symptoms [ Time Frame: At 3 months and at 6 months ]
    Between-group magnitude of change in sum score using the self-report measure, Cognitive Failures Questionnaire (CFQ). The scoring range is 0-100. Higher scores indicate more severe cognitive symptoms.

  7. Change in Work/School Status [ Time Frame: At 3 months and at 6 months ]
    Change in total score using the self-report questionnaire about their work/school status.

  8. Change in Physical Activity [ Time Frame: At 3 months ]
    Change in total score based on weekly self-report dairy about physical activity during training period.

  9. Change in Diet [ Time Frame: At 3 months ]
    Change in total score based on weekly self-report dairy about diet during training period.

  10. Change in Social Activity [ Time Frame: At 3 months ]
    Change in total score based on weekly self-report dairy about social activity during training period.

  11. Change in Sleep [ Time Frame: At 3 months ]
    Change in total score based on weekly self-report dairy about sleep during training period.

  12. Change in Functional Abilities [ Time Frame: At 3 months ]
    Change in total score based on weekly self-report dairy about functional abilities during training period.
