Pediatric Stroke: Global Burden and Changing Epidemiological Trends

Pediatric stroke remains a significant global health concern, despite improvements in neonatal and childhood healthcare. Although better clinical care has reduced stroke-related mortality and disability over the past three decades, millions of children continue to experience its consequences, particularly in low- and middle-income countries (LMICs).

A global analysis published in Pediatric Discovery on December 31, 2025 (DOI: 10.1002/pdi3.70031), examined pediatric hemorrhagic stroke (HS) and ischemic stroke (IS) across 204 countries and territories. Researchers from Children’s Hospital of Chongqing Medical University, the National Clinical Research Center for Child Health and Disorders, and Army Medical University analyzed Global Burden of Disease (GBD) 2021 estimates from 1990 to 2021.

In 2021, approximately 2.7 million children and adolescents were living with stroke worldwide. Ischemic stroke accounted for 58.6% of cases, while hemorrhagic stroke represented 41.4%.

However, the distribution of severe outcomes differed considerably. Hemorrhagic stroke contributed 78.3% of stroke-related DALYs and 85.9% of deaths, highlighting its disproportionate impact on childhood survival and long-term health.

Although global stroke-related DALYs declined from approximately 5.9 million in 1990 to 2.4 million in 2021, annual deaths still reached approximately 24,700 in 2021. More concerningly, incident cases among adolescents aged 10–19 increased from approximately 144,300 to 152,500.

Regional Disparities and Risk Factors in Childhood Stroke

The analysis identified substantial geographical and demographic differences in pediatric stroke epidemiology. Low-SDI regions carried the highest age-standardized burden, particularly for hemorrhagic stroke. Its prevalence in these settings increased from approximately 146,600 cases in 1990 to 267,200 in 2021.

Western Sub-Saharan Africa recorded the steepest increase in hemorrhagic stroke prevalence, while East Asia experienced the largest decline. China reported the highest number of prevalent pediatric stroke cases, whereas India recorded the highest DALYs and incident cases in 2021.

Researchers also identified differences between sexes. Males experienced more hemorrhagic stroke, while females had more ischemic stroke. Stroke incidence increased with age, reaching its highest levels among adolescents aged 15–19.

Infections, congenital heart disease, sickle cell disease, and trauma remain important contributors to childhood stroke risk. Limited access to diagnostic imaging, emergency interventions, and neurosurgical services further increases complications in resource-limited healthcare systems.

Improving Pediatric Stroke Care Through Early Intervention and Rehabilitation

The findings emphasize that declining mortality does not reflect equal progress across populations. Children in resource-limited settings continue to face substantial risks, particularly from hemorrhagic stroke and its long-term complications.

The researchers highlight three priorities: improving acute stroke management, strengthening age- and sex-specific prevention strategies, and expanding physical, occupational, and speech rehabilitation.

For pediatric neurologists, emergency physicians, nurses, and rehabilitation specialists, early recognition and timely referral remain essential. Better diagnostic access, coordinated referral pathways, telemedicine, and thrombectomy where clinically feasible could improve outcomes.

The authors also call for additional research into the economic burden of pediatric stroke and the effectiveness of interventions in LMICs.

Addressing these disparities requires healthcare systems to combine improvements in neonatal care with adolescent-focused prevention, accessible emergency treatment, and long-term rehabilitation. These measures could help reduce preventable childhood deaths, disability, and inequalities in pediatric stroke care.
