Cross-National Study of 214000 Adults Finds Dementia Risk Factor Prevalence Varies Sevenfold by Region
Observational cross-national comparison reveals substantial regional heterogeneity in dementia risk factor burden while documenting stable clustering of cardiometabolic and behavioral risks. Findings challenge one-size-fits-all prevention and support tailored public health strategies in low- and middle-income countries.
Next steps include expanding the harmonized platform to Kenya and Egypt and testing cluster-targeted interventions. Policymakers can now prioritize cardiometabolic bundles in middle-income settings rather than single-factor programs imported from high-income trials.
Nichols: By 2028, three or more LMICs will publish national dementia plans that explicitly target cardiometabolic clusters identified in the Gateway data, with measurable uptake thresholds above 40 percent of at-risk adults.
