Brief Summary
Despite potent combination antiretroviral therapy, cognitive (memory and concentration) problems continue to occur in up to 50% of HIV-infected individuals, especially in older infected individuals, and those who abuse alcohol, marijuana or psychostimulants. Since no effective treatments are available to these individuals with cognitive problems, conservative estimates indicate that the cost of care for these patients could double in the next two decades. To address this urgent problem, this study will use a comprehensive approach (cognitive tests, functional MRI and several biomarkers) to evaluate whether a novel computer-based training program would improve the brain function, especially working memory and attention, in HIV-infected and infected individuals.

Outcome Measures
Primary Outcomes (3)
Changes in the Improvement Index on Cogmed™
This is generated by the computer training program based on the trained tasks.
1 month after training, and 6 month after training completion

Verbal working memory and spatial working memory tasks
1 month after training, and 6 month after training completion
Changes in Blood-Oxygenation Level-Dependent Functional MRI Measures
Brain activation during the performance of working memory and attention tasks
1 month after training, and 6 month after training completion
Secondary Outcomes (3)
Changes in cognitive performance based on LIM homeobox transcription factor 1 alpha (LMX1A) genotypes (AA vs. GA/GG)
Baseline, 1 month after training, and 6 month after training completion
Changes in Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A)
1 month after training, and 6 month after training completion
Changes in Blood-Oxygenation Level-Dependent Functional MRI Measures based on LMX1A genotypes
1 month after training, and 6 month after training completion
Study Arms (2)
HIV Positive participants
EXPERIMENTALIntervention; 90 HIV positive participants will be trained. Half the participants will have the Adaptive WM Cogmed training, and half will have the non-adaptive WM Cogmed training.
Seronegative particpiants
OTHERIntervention; 90 seronegative participants will be trained. Half the participants will have the Adaptive WM Cogmed training, and half will have the non-adaptive WM Cogmed training.
Interventions
12 different computerized visual and spatial Working Memory tasks will be presented at each sessoin. Each session will involve 8 of the 12 tasks, and each subject is required to complete 25 training sessions, 30-40 minutes per day, 4-5 days per week over a 5-8 week period (minimum 20 sessions). The tasks will become more difficult in an "adaptive" manner, which is hypothesized as optimal for learning and training effects.
The same 12 computerized visual and spatial working memory tasks will be presented, but at a fixed ("non-adaptive") and low difficulty level. 5 sessions per week x 5 weeks fora total of 25 sessions (minimum 20 sessions).
