Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In addition to the above prospective component, this study also has a retrospective component in which archival data collected from routine clinical care will be examined for analysis. The investigators hope to gain a better understanding of the unique and cumulative influence different cognitive rehabilitation programs have on improving attention complaints in mTBI.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The objective of this proposal is to evaluate the effectiveness of rehabilitation for visual attention deficits in U.S. military service members across three programs:
1. Visual Attention and Memory Program (UCR Games)
2. Cognitive and Psychological Based Rehabilitation (Speech Pathologist-Directed Therapy)
3. General Cognitive Rehabilitation Games (Lumosity \[2\])
The investigators hope to gain a better understanding of the unique and cumulative influence of different cognitive rehabilitation programs on improving attention complaints in mTBI. This proposal contains both retrospective and prospective components.
The retrospective component consists of examining archival data from Lumosity, previously collected as part of routine clinical care. The data contain pre- and post-assessments of post-concussive symptoms, symptom frequency, and cognitive testing. The investigators expect that data analysis will reveal evidence of improvement in severity of post-concussive symptoms, in frequency of troublesome cognitive problems, and in performance on neuropsychological tests when pre- and post-assessments are compared.
The prospective component will consist of 120 service members with mTBI who have ongoing attention complaints and are more than three months post-injury. Each service member will be randomly assigned to one of four arms, differentiated only by the specific computer-based rehabilitation program used. All individuals will also be treated per current standard of care guidelines by a speech pathologist.
Each of the four arms will be comprised of 30 participants. A cognitive testing battery will be administered to each participant before and after implementation of each intervention. The cognitive testing battery form will vary based on time of administration in order to control for practice effects. Performance on the cognitive testing battery and self-report measures will be compared between and within the three arms.
This research will help the military to identify the best cognitive rehabilitation treatment program to address ongoing attention complaints following mTBI.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
A: UCR Games→SP-Directed Therapy
Participants in Arm A will first participate in Visual Attention Program (UCR Games) followed by Speech Pathologist-Directed Therapy with assessment sessions prior to and following each treatment intervention.
Visual Attention Program (UCR Games)
This program is an individual-directed computerized cognitive rehabilitation program based on perceptual learning approaches to enhance visual attention. Training incorporates a diverse set of stimuli, optimized stimulus presentation, multisensory facilitation, and consistently reinforcing training stimuli. This will be completed in a group setting with an instructor available to facilitate questions.
Speech Pathologist-Directed Therapy
This is a speech pathologist-directed arm and will provide a traditional clinician-directed individualized cognitive rehabilitation program. Cognitive treatment is a systematic, functionally oriented program of therapeutic activities that focuses on strengthening previously learned patterns of behavior, establishing new patterns through use of internal and external compensatory cognitive strategies, and enabling the individual to adapt to the changes in his or her revised approaches to cognitive functioning. Increased performance success is reinforced through repetition, errorless learning, and gradually increasing task stimuli and complexity in a structured systematic approach.
B: Lumosity→SP-Directed Therapy
Participants in Arm B will first participate in General Cognitive Rehabilitation Games (Lumosity) followed by Speech Pathologist-Directed Therapy with assessment sessions prior to and following each treatment intervention.

General Cognitive Rehabilitation Games (Lumosity)
Lumosity is a commercially available computerized program purported to enhance cognitive functioning through a variety of computerized programs that utilize various cognitive abilities.
