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 data from 1990 to 2023 and found that ADHD-related disability remained concentrated in childhood and adolescence, with consistently higher rates among males.
The research, led by investigators from Kyung Hee University College of Medicine in Seoul, South Korea, with collaborators at other institutions, used the Global Burden of Disease Study 2023 to analyze years lived with disability (YLDs) across five Asian regions. The findings reveal marked regional heterogeneity rather than a uniform pattern. East Asia carried the highest regional burden in 2023 and followed an upward trend, with Japan and China recording the largest national estimates. In contrast, Southeast Asia showed a decline over the study period.
Across all regions, ADHD-related disability peaked at ages 10–14 and then declined progressively, a pattern 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, though the authors caution that these patterns cannot establish that the pandemic caused the increase.
The study's implications are significant for health systems, schools, and families. The concentration of disability in early adolescence makes timely recognition especially important, the authors said, while the consistently higher estimates among males should not obscure girls whose symptoms may be less readily noticed. 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.
The authors emphasize that differences between countries require careful interpretation: better detection, health service access, and reporting can influence estimated burden. Higher socioeconomic development was associated with higher estimated ADHD disability, a relationship that may partly reflect differences in recognition and access to diagnosis rather than underlying disease alone. Because estimates are modeled and shaped by diagnostic and reporting differences, they should guide planning and monitoring rather than rank health systems.
The full study is available via its published DOI. As ADHD remains the most common neurodevelopmental disorder, imposing a lifelong burden that extends to academic achievement, quality of life, and long-term disability, these findings offer a clearer picture of where support is most needed and could help health systems target earlier identification, appropriate care, and school-based assistance across Asia.
