A global analysis of pediatric stroke reveals that while overall deaths and disability-adjusted life years (DALYs) have fallen substantially over three decades, the burden is increasingly concentrated among adolescents and in low-sociodemographic-index (SDI) regions. The study, published in Pediatric Discovery, used Global Burden of Disease 2021 estimates to track hemorrhagic stroke (HS) and ischemic stroke (IS) among children and adolescents aged 0–19 years across 204 countries and territories from 1990 to 2021. The findings matter because they challenge the narrative of uniform progress and highlight where health systems are failing the most vulnerable.
In 2021, an estimated 2.7 million children and adolescents were living with pediatric stroke; HS accounted for 41.4% and IS for 58.6%. Stroke-related DALYs fell from about 5.9 million in 1990 to 2.4 million in 2021, and deaths numbered about 24,700. However, incident cases among adolescents aged 10–19 years rose from approximately 144,300 to 152,500, with incidence peaking at ages 15–19. HS remained disproportionately severe, contributing 78.3% of DALYs and 85.9% of deaths. Low-SDI regions carried the highest age-standardized burdens, with HS prevalence rising from about 146,600 cases in 1990 to 267,200 in 2021; their HS-related age-standardized DALY rate reached 4,157.3 per 100,000. Western Sub-Saharan Africa recorded the steepest prevalence increase (estimated annual percentage change 2.60), while East Asia achieved the largest decline (−1.28). China had the most prevalent cases (about 350,200), whereas India had the most DALYs (about 227,300) and incident cases in 2021. Males had more HS, while females had more IS. The highest HS age-standardized prevalence rate occurred in low-SDI settings (222.0 per 100,000), whereas the highest IS rate occurred in high-SDI settings (316.3 per 100,000). Adolescent DALYs in low-SDI regions rose for both subtypes, and the authors reported a modest post-2015 rebound in age-standardized prevalence.
The authors caution that falling DALYs and deaths should not be read as a simple success story. Better neonatal and pediatric care in high-income settings have reduced mortality and disability, but rising adolescent incidence and persistently high HS mortality in low-SDI regions signal uneven progress. HS causes most pediatric stroke DALYs, especially where timely neurosurgical care is unavailable. Infections, congenital heart disease, trauma and sickle cell disease further shape risk. The study supports three priorities: improving acute stroke care, especially for HS in low-resource settings; strengthening prevention with age- and sex-specific strategies; and expanding rehabilitation. Better referral pathways, telemedicine, thrombectomy where feasible, and routine surveillance could improve early recognition and outcomes. Because the burden is increasingly concentrated in low-SDI regions and among adolescents, funders and health systems should pair neonatal-care gains with adolescent-focused prevention and rehabilitation. The authors also call for research on economic costs and intervention effectiveness in low- and middle-income countries, where families often bear catastrophic expenses. Such investments could reduce long-term disability and inequity. For health systems worldwide, the message is clear: progress must be measured not only in aggregate declines but in whether the highest-risk children actually receive timely, effective care.
