A comprehensive analysis of attention-deficit/hyperactivity disorder (ADHD) across 34 Asian countries has identified ages 10 to 14 as the period when the disorder's impact on daily functioning is greatest. Published online on October 9, 2026, in the World Journal of Pediatrics, the study examined ADHD-related years lived with disability (YLDs) from 1990 to 2023 using the Global Burden of Disease Study 2023. The findings matter because they provide a regional map of where and when support is most needed, offering health systems and schools a clearer basis for targeting early identification, appropriate care, and school-based assistance.
ADHD is the most common neurodevelopmental disorder and imposes a lifelong burden that extends beyond core symptoms to academic achievement, quality of life, and long-term disability. Yet comparable evidence across Asia has been limited, with earlier studies often focused on single countries, restricted age groups, or selected regions. Healthcare access, diagnostic practices, educational environments, and public awareness vary widely across the continent, complicating regional and national comparisons. The COVID-19 pandemic further disrupted schooling, routines, and service access, adding uncertainty about whether observed changes reflect true burden or shifts in recognition and reporting.
The study, conducted by leading researchers from Kyung Hee University College of Medicine in Seoul, South Korea, with collaborators at other institutions, found marked regional heterogeneity rather than a uniform Asia-wide pattern. East Asia carried the highest regional burden and followed an upward trend, while Japan and China recorded the largest national estimates. In contrast, Southeast Asia moved in the opposite direction and declined over the study period. Across all regions, ADHD-related disability was concentrated in childhood and early adolescence, peaked at ages 10–14, and then declined progressively; this age peak was particularly pronounced in East Asia. Males consistently had higher rates than females across regions and age groups.
The team also compared changes among children aged 0–14 before the pandemic (2015–2019) and during the subsequent period (2019–2023). Most countries showed increases, with the Republic of Korea shifting from a decline to a marked rise, although these patterns cannot establish that the pandemic caused the increase. Higher scores on the Socio-demographic Index were associated with higher estimated ADHD disability, a relationship that may partly reflect differences in recognition and access to diagnosis rather than underlying disease alone. The authors emphasized that these regional contrasts indicate Asia-wide averages can obscure important national differences and should be interpreted alongside local diagnostic and service contexts.
The implications for policy and practice are direct. Schools can train teachers to recognize diverse ADHD presentations—including less obvious inattentive symptoms in girls—and strengthen referral pathways, classroom management, and social–emotional learning, especially around ages 10–14. Clinicians can prioritize early assessment in this age group, attend to sex-specific symptom profiles, integrate screening into primary care, and link families to evidence-based behavioral support. Policymakers can use these regional patterns to target resources, emphasize early identification and timely treatment, and expand school- and primary-care-based services where specialist capacity is limited. Because estimates are modeled and shaped by diagnostic and reporting differences, the authors caution they should guide planning and monitoring rather than rank health systems.
