Cardiovascular Disease as a Predictor of Dementia: A Cross‐National Ecological Study of 204 Countries

This study demonstrates a robust population-level association between CVD and dementia across global settings, particularly in resource-limited regions. Findings underscore the importance of integrated public health approaches targeting shared vascular risk factors. Given the ecological design, further individual-level, longitudinal research is needed to clarify causal pathways and inform targeted interventions.
