摘要

Background

Neurological disorders represent a significant global health issue, leading to severe cognitive impairments and being a major cause of premature mortality and disability. This study aims to utilize data from the Global Burden of Disease (GBD) research website to assess the burden of neurological disorders in the Asian region and its individual countries and territory from 1990 to 2021, with the goal of providing reference for global efforts and decision-making in the prevention, treatment, and management of neurological disorders.

Methods

Based on the Global Burden of Disease data, this study assessed the incidence, prevalence, mortality, and disability-adjusted life years (DALYs) of 13 neurological disorders in the Asian region from 1990 to 2021. The epidemiological characteristics of neurological disorders across these Asian regions were analyzed. Joinpoint regression analysis was employed to assess the temporal patterns of the burden of neurological disorders, and the average annual percent change (AAPC) was calculated to determine the overall trend throughout the study period.

Results

In 2021, stroke, migraine, and Alzheimer’s disease and other dementias emerged as the primary contributors to neurological burden in Asia, with stroke accounting for 112.87 million disability-adjusted life years (DALYs), followed by migraine (25.4 million) and Alzheimer’s disease and other dementias (20.0 million). Stroke was also the leading cause of neurological mortality (5.03 million deaths), trailed by Alzheimer’s disease and other dementias (1.0 million). Stroke, migraine, and tension-type headache had the highest prevalence rates among neurological disorders, with 57.3 million, 683.5 million, and 1130.2 million. Temporal trends from 1990 to 2021 revealed a significant decline in age-standardized DALY rates for stroke (estimated annual percentage change [EAPC]: − 1.65%), though absolute DALYs increased (EAPC: 0.06%). In contrast, Alzheimer’s disease and other dementias exhibited rising age-standardized (EAPC: 0.14%) and absolute DALYs (EAPC: 2.8%), while infectious neurological diseases (e.g., meningitis, tetanus) demonstrated marked reductions in burden. Sex-specific disparities were evident, with males experiencing a higher total DALY burden (84.8 million vs. 77.05 million), driven by stroke and Parkinson’s disease, whereas Alzheimer’s disease and other dementias and migraine disproportionately affected females. Geographically, stroke dominated Southeast Asia (67.6% of regional DALYs), while migraine contributed most substantially to West Asia (16%). Nationally, stroke ranked as the leading cause of neurological DALYs in most Asian countries, contrasting with migraine in Israel, Kuwait, Qatar, and the United Arab Emirates. Longitudinal analyses highlighted accelerated declines in stroke DALYs post- 2004 but escalating burdens for Alzheimer’s disease and other dementias after 2019, reflecting divergent epidemiological trajectories.

Conclusions

In 2021, the burden of neurological disorders in Asia remained substantial, with stroke, migraine, and Alzheimer’s disease and other dementias being the top three contributors to DALYs. The study also revealed significant differences in the burden of neurological disorders across various subregions and countries in Asia, highlighting the need for enhanced international collaboration, sharing of best practices, provision of technical support, and optimization of healthcare resource allocation.
