Early antiretroviral therapy (ART) has improved neurodevelopmental outcomes of HIV‐infected (HIV‐positive) children; however, little is known about the longer term outcomes in infants commencing early ART or whether temporary ART interruption might have long‐term consequences. In the children with HIV early antiretroviral treatment (CHER) trial, HIV‐infected infants ≤12 weeks of age with CD4 ≥25% were randomized to deferred ART (ART‐Def); immediate time‐limited ART for 40 weeks (ART‐40W) or 96 weeks (ART‐96W).

A prospective, longitudinal observational study was used. The Griffiths mental development scales (GMDS), which includes six subscales and a global score, were …
