The brain of a child Understanding cognitive development
The brain of a child: Understanding cognitive development for children living with HIV Prof Lorraine Sherr, University College London Member Coalition for Children Affected by AIDS
Presentation AIM • Review the evidence of cognitive impact of HIV for HIV+ve and HIV exposed and Uninfected children • Explore the complexity of responding to cognitive challenges • Community Care study data the role of cash grants, and cash plus care, cash plus nutrition on cognitive outcomes • Chido trial data to show parental factors impact on cognitive outcomes • Examine promising interventions
Cognitive development HIV+ve Children • Systematic reviews • Sherr et al 2009; Sherr et al 2015 • Mc. Henry et al 2018 45 Studies Both HIV+ve and HEU children had worse developmental outcomes compared to HIV Uninfected Unexposed Children. HEU • Cognitive delay • Systematic review – 11 studies (650 HIV affected, 736 Control 205 HIV+ve) Sig lower than controls on at least 1 measure in 7/11 studies. (Sherr et al AIDS Behav 2014, Nov 18(11) 205974); Le Doare et al Pediatrics 2012 Nov 130(5)e 1326 -44 • Morbidity and Mortality effects • Slogrove et al 2016 – 22 studies, 3 specifically designed.

CONCLUSION Cognitive challenges exist for some – not all Extends beyond HIV+VE to HEU Time to intervene is overdue Evidence base of efficacy – where is the roll out?
