Population neuroscience meets syndemics to explain dementia sex and gender risk in LMICs
Mar 2nd 2026
A global team proposes a Population Neuroscience-Dementia Syndemics Framework to study how biological, social, and structural factors interact across the lifecourse to drive higher dementia risk for women in low and middle income countries.
- Low and middle income countries carry a large share of the global dementia burden and older women face higher risk than men.
- Most neuroscience studies to date are small and highly selected, limiting how well findings apply to LMIC populations.
- The Population Neuroscience-Dementia Syndemics Framework merges multilevel, lifecourse brain research with syndemic theory to study interacting diseases and social conditions.
- The framework centers structural and social determinants such as sociocultural, political, economic, and environmental factors as drivers of dementia risk.
- Authors recommend larger, more representative studies and research tools that improve both internal and external validity.
- The goal is to generate locally relevant prevention and policy insights by capturing how multiple conditions and stress pathways cluster and interact in communities.
