Mental and Psychological Problems Affect Over 50% in U.S. HIV Group

March 2011

Slightly more than half of HIV-positive adults in a new nationwide US study have some form of neuropsychological (NP) impairment, which includes problems that affect the brain (like mental sharpness and memory) and the mood (like depression).1 People with a lowestever (nadir) CD4 count under 200 had a higher risk of NP impairment in this study, even if they were taking antiretroviral therapy.

The most severe form of NP impairment, HIV-associated dementia, has become rarer since the arrival of triple antiretroviral combinations. But other conditions involving the central nervous system (HIV-associated neurocognitive disorders, or HAND) persist.2,3 To gain a better understanding of HAND in recent years, US researchers organized the CHARTER study at six university HIV clinics across the country. This report focuses on rates of NP impairment and risk factors for NP impairment in these people.
