This study evaluates trends in incidence, prevalence, mortality, and Disability-Adjusted Life Years (DALYs) associated with neurological diseases in these countries from 1990 to 2021, focusing on sex disparities and key risk factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data were obtained from the Global Burden of Disease (GBD) 2021 database. Join point regression and Estimated Annual Percentage Change (EAPC) analyses were used to assess trends in neurological disease burden. Age-standardized rates for incidence, prevalence, and mortality were calculated, along with DALYs, and key risk factors were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>China showed the largest increase in incidence (7541.89 to 8031.37 per 100,000) and prevalence (26494.85 to 28534.79 per 100,000). Mortality increased in India (21.01 to 24.27 per 100,000) and South Africa (27.66 to 30.65 per 100,000), while China showed a decline (39.59 to 37.30 per 100,000). Brazil experienced a substantial rise in DALYs (1610.65 to 42024.59). Sex disparities showed higher DALY rates for females across all nations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The research highlights the rising burden of neurological disorders in BRICS nations, especially in China and Brazil due to aging populations and metabolic risks. It emphasizes the need for targeted interventions in India and South Africa, where increasing mortality rates and DALYs are concerning. Effective health policies should focus on early detection, managing metabolic risks, and implementing sex-specific strategies to address these issues.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fneur.2024.1500551","type":"journal-article","created":{"date-parts":[[2024,12,5]],"date-time":"2024-12-05T05:10:59Z","timestamp":1733375459000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Burden of neurologic diseases in BRICS countries (1990 to 2021): an analysis of 2021 Global Burden of Disease Study"],"prefix":"10.3389","volume":"15","author":[{"given":"Shubham","family":"Chauhan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shilpa","family":"Gaidhane","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.
