Association of blood-based neurodegenerative biomarkers with cognitive functioning and dementia in India (LASI-DAD) and the United States (HRS)

16 Aug 2025

Abstract excerpt

This study examines associations between blood-based neurodegenerative biomarkers and cognitive functioning in nationally representative samples of older adults in India and the United States. Using data from the Longitudinal Aging Study in India-Diagnostic Assessment of Dementia (LASI-DAD) and the Health and Retirement Study (HRS), we analyzed 4 biomarkers-the ratio of Amyloid beta 42-40 (Aβ42/Aβ40), Glial...
