Mapping the brain in younger and older asymptomatic HIV-1 men: frontal volume changes in the absence of other cortical or diffusion tensor abnormalities.

Introduction: Over the past decade the developments made in treating people with human immune deficiency virus (HIV) have greatly improved quality of life and life expectancy. However, the nature of asymptomatic HIV-associated minor neurocognitive disorder (HAND) remains unclear. In this study we explored the occurrence of neuropsychological and neuroimaging changes in medically and psychiatrically stable HIV-1 infected patients on highly active antiretroviral treatment (HAART) from two separate age groups.
