HIV Variants in Spinal Fluid May Hold Clues in Development of HIV-related Dementia

Science Update

NIMH-funded researchers found two variants of HIV in the cerebrospinal fluid (CSF) of infected study participants that were genetically distinct from the viral variants found in the participants’ blood. The study, published October 6, 2011, in the journal PLoS Pathogens, suggests these CSF variants may help to inform research on the development and treatment of cognitive problems related to HIV infection.
