White matter micro-structural changes in ART-naive and ART-treated children and adolescents infected with HIV in South Africa

Children infected with HIV, irrespective of treatment status, displayed significantly poorer white matter integrity and impaired cognition compared to HIV-negative controls. Our findings suggest that despite immune recovery in children on ART, they remain at risk for developing central nervous system disease, and that initiation of ART as early as possible may reduce the risk of developing white matter damage in ART-naive slow progressors.
