A Global, Regional, and National Survey on Burden and Quality of Care Index of Alzheimer’s Disease and Other Dementias in Adults Aged 55 and Above: The Global Burden of Disease Study 1990–2021

Key Points

A substantial disparity in quality of care index exists globally among older adults, indicating significant inequalities.
The analysis shows notable differences in quality of care based on age and gender, affecting care accessibility.
Observational analysis across multiple regions from the Global Burden of Disease Study highlights urgent care gaps.
Improving care access and quality for Alzheimer's disease and other dementias is crucial for alleviating the overall burden.

Abstract

Substantial disparities in QCI exist globally and regionally across age cohorts and between men and women. Policymakers should prioritize targeted interventions to address these gaps, improve access to high-quality care, and alleviate the global burden of ADOD.
