  "abstract": "Introduction/Purpose 85% of spontaneous subarachnoid hemorrhage (SAH) is caused by intracranial aneurysm rupture. Despite advancements, SAH remains fatal in 65% of patients and results in permanent disability in 50% of survivors. Prior Global Burden of Disease (GBD) analyses demonstrated a disproportionate burden in middle-income countries. We used updated 2023 GBD data to reassess global SAH burden and evaluate evolving socioeconomic and regional disparities.Materials and Methods We used the updated GBD database to extract mortality and years lived with disability (YLD) per 100,000 individuals attributable to SAH across all countries from 1990 to 2023. We collected gross domestic product (GDP) per capita, United Nations geoscheme region, Healthcare Access and Quality Index (HAQI), and neurosurgeons per capita when available.Results 15/20 (75%) countries with the highest SAH death burden ( table 1) fell within the middle 50% of GDP per capita, while 14/20 (70%) countries with the highest YLD burden (table 2) fell within this range. In contrast to prior analyses, a majority of high-burden countries clustered in East Asia and the Pacific Islands, including 15/20 (70%) countries contributing to mortality and 12/20 (60%) contributing to YLD. From 1990 to 2023, countries demonstrated an initial rise in SAH burden followed by a decline with increasing economic development.Conclusion Updated 2023 data demonstrate persistent concentration of SAH burden in middle-income countries, with regional clustering in East Asia and the Pacific. Divergence between mortality and disability across income levels suggests that access to advanced, resource-intensive care improves survival but increases long-term disability. Limited availability of endovascular treatment, neurocritical care, and vasospasm management likely contributes to these disparities. For neurointerventional practice, these findings identify regions where expanding access to aneurysm treatment and comprehensive SAH care may yield the greatest improvements in survival and functional outcomes.Disclosures M.
