Translational spatial task and its relationship to HIV-associated neurocognitive disorders and apolipoprotein E in HIV-seropositive women.

HIV-associated neurocognitive disorders (HAND) continue to be a neurological complication of HIV infection in the era of combined antiretroviral therapy. Hippocampal neurodegeneration and dysfunction occurs as a result of HIV infection, but few studies to date have assesses spatial learning and memory function in patients with HAND. We used the Memory Island (MI) test to study the effects of HIV infection, apolipoprotein E (ApoE) allele status, and cerebral spinal fluid (CSF) ApoE protein levels on spatial learning and memory in our cohort of Hispanic women.

Associations of cigarette smoking with viral immune and cognitive function in human immunodeficiency virus-seropositive women.

Cigarette smoking alters the immune system and may improve cognitive deficits in neuropsychiatric disorders. Smoking prevalence is high in human immunodeficiency virus (HIV)-infected patients; however, its effect on HIV-associated cognitive impairment remains unknown in the era of antiretroviral treatment. The authors examined associations of smoking with viral immune profile and cognitive function in a cohort of HIV-seropositive women.
