HIV-seropositive individuals with low cognitive reserve are at high risk for developing HIV-associated neurocognitive disorders (HAND). The present study evaluated the hypothesis that cognitive reserve would also play a unique role in the expression of everyday functioning complications among those with HAND (i.e., syndromic versus subsyndromic impairment). Eighty-six individuals with HIV infection were evaluated; 53 individuals evidenced normal neurocognitive performance, 16 had subsyndromic HAND (i.e., asymptomatic neurocognitive impairment), and 17 were diagnosed with syndromic HAND based on a comprehensive neurobehavioral evaluation. Cognitive reserve represented a combined score including years of education, estimated verbal IQ, and highest occupational attainment. The groups were comparable (e.g. demographics), and the HAND groups had similar rates of global neurocognitive impairment. The syndromic HAND group evidenced lower reserve scores relative to both other groups, suggesting that individuals with lower reserve may be less able to effectively counteract their neurocognitive impairment to maintain independence in daily living activities than HIV-infected individuals with high cognitive reserve.
