Abstract
HIV-associated neurocognitive disorders (HAND) are a group of conditions ranging from asymptomatic neurocognitive impairment to disabling dementia. The clinical spectrum and pathogenesis of these disorders is changing in the era of highly active antiretroviral therapy (HAART). High levels of HIV may exist in the cerebrospinal fluid (CSF) of some patients despite suppression of serum viral loads by HAART. We report a case of a 51-year-old male with profound levels of HIV in the CSF despite low serum levels. Adjusting his HAART regimen based on HIV genotype susceptibility data and a CNS Penetrating Effectiveness (CPE) score resulted in a dramatic improvement in cognitive function. Progressive dementia in this context is a rare but emerging trend and may be reversible.
