COMPARING ATTENTION DEFICIT HYPERACTIVITY DISORDER (ADHD) PREVALENCE, AWARENESS AND INTERVENTION SYSTEMS AMONG ADOLESCENTS AND SCHOOL-AGE CHILDREN ACROSS LOW- AND MEDIUM-INCOME VERSUS HIGH-INCOME COUNTRIES: A SCOPING REVIEW

Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent neurodevelopmental disorders among children and adolescents, with significant academic, social, and health impacts. While prevalence and intervention strategies are well documented in high-income countries (HICs), evidence from low- and middle-income countries (LMICs), especially in Sub-Saharan Africa, remains sparse. Aside a comprehensive investigation of the condition in LMICs, intimate comparative evidence is needed to understand cultural and systemic differences in awareness, diagnosis, and intervention systems across contrasting socioeconomic contexts. The primary objective of this study therefore is to map and synthesize existing comparative evidence on ADHD awareness, prevalence, and intervention strategies among school-age children and adolescents across intimately compared HICs and LMICs contexts. The aim is to understand how researchers in literature have compared ADHD in HIC versus LIMCs in terms of awareness, prevalence and intervention strategies.
