Significance: Using Fascati criteria, 52% - 59% of people with HIV experience HIV-associated Neurocognitive Disorder (HAND) which affects driving safety, medication adherence, and instrumental activities of daily living (IADLs). Cognitive aging in this group represents a major concern since by 2020, 70% of adults with HIV in the United States will be 50 and older. Thus, there is a growing population that is particularly vulnerable to HAND due to the co-occurrence with aging-related cognitive impairments. In our prior study (R03MH076642-01A2) conducted in the HAART era, when comparing cognitive functioning between older and younger HIV-positive and HIV-negative adults, older adults with HIV performed the worst. In the HAART era, these cognitive impairments continue to be observed in several cognitive domains including memory, reasoning/executive functioning, and one area of particular importance - speed of processing.
