ADHD disability burden peaks at 10 to 14 across Asia, study finds

A 34-country analysis finds the impact of ADHD is greatest in early adolescence, with boys most affected and major differences between Asian regions.

A new analysis of attention-deficit/hyperactivity disorder across Asia suggests that the condition’s disability burden is not evenly distributed, but instead rises sharply in early adolescence before easing in later years. The study, published online in the World Journal of Pediatrics, examined data from 34 Asian countries and found that the heaviest impact was concentrated between the ages of 10 and 14, with boys consistently showing higher estimated rates than girls.

Researchers from Kyung Hee University College of Medicine in Seoul and collaborating institutions used data from the Global Burden of Disease Study 2023 to track ADHD-related years lived with disability from 1990 to 2023. That measure captures the time people live with health-related impairment, offering a broader picture than diagnosis counts alone. The analysis found striking regional differences: East Asia carried the highest burden and showed an upward trend over time, while Southeast Asia moved in the opposite direction and declined.

At the national level, Japan and China recorded the largest estimates, but the authors cautioned against reading those figures as a simple measure of underlying prevalence. Higher rates in more developed settings may reflect better recognition, stronger diagnostic systems and greater access to care as much as, or more than, true differences in disease burden. The study also found that countries with higher socio-economic development tended to show higher estimated disability, reinforcing the likelihood that detection and reporting practices shape the picture as well as the condition itself.

The researchers said the findings point to a need for earlier recognition, especially during the school years when ADHD-related disability appears to peak. They argued that teachers should be better trained to spot a wider range of symptoms, including inattentive presentations that may be less visible in girls, while clinicians should consider more active screening in primary care and families should be linked to evidence-based behavioural support. The study also noted that most countries saw increases in the child age group during and after the COVID-19 period, though the authors stressed that these were observed trends rather than proof that the pandemic directly caused them.
