Spatial working memory in asymptomatic HIV-infected subjects.
Many clinical and research findings converge to indicate that frontal lobe, basal ganglia, and related neuronal connections are primarily involved in human immunodeficiency virus (HIV) infection; frontal lobe, mainly the prefrontal cortex, has a specialized role in working memory processes. This study focused on neuropsychological evaluation of the spatial component of working memory in a sample of 34 asymptomatic HIV-infected subjects as compared with 34 age- and sex-matched seronegative control subjects. A computer-administered test assessing spatial working memory was used for the neuropsychological evaluation. The findings did not show any spatial working memory impairment during the asymptomatic phase of HIV infection.
