The purpose of this study is to contribute evidence towards the potential to improve cognition in HIV+ individuals experiencing cognitive decline through personalized change in antiretroviral (ARV) medication. To that end, following a comprehensive evaluation to identify confounding clinical conditions, study participants will undergo a lumbar puncture to: (i) measure viral load (at 2 copies/ml); (ii) identify Cerebrospinal Fluid (CSF) genotype and tropism; and (iii) measure concentration of antiretroviral agents. When indicated from the CSF analysis, a personalized change in ARV will be implemented. Cognition will be measured in all at study entry and 6 months later.

Primary Outcome Measures:
  • Changes in neurocognitive functioning over 6 months [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    Cognition will be assessed at study entry and 6 months with the following tests: Letter Fluency, Category Fluency, Letter-Number Sequencing, Digit-Symbol, Symbol Search, Grooved Pegboard, Hopkins Verbal Learning Test-Revised, Stroop, Brief Visuospatial Memory Test-Revised, Tower of London, Trail Making Test A and B, Spatial Span, Montreal Cognitive Assessment (MoCA), and a brief computerized battery of tests (B-CAM).

Estimated Enrollment: 25
Study Start Date: June 2011
Estimated Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
