Associations between neurodegenerative plasma biomarkers and cognitive functioning and decline in India

Findings are consistent with prior studies and support the use of neurodegenerative biomarkers in India. Future research should leverage these biomarkers in the Indian context to address a range of research topics, including heterogeneity in dementia phenotypes, links between dementia risk factors and neurodegenerative biomarkers, and interactions between neurodegenerative biomarkers and vascular health in their effects on cognitive outcomes. Biological heterogeneity of dementia and interactions with vascular health warrant further research.
