What this research studies

This project combines data from 18 long-term twin studies around the world to compare education, occupations, and later-life memory and dementia outcomes. Researchers will harmonize education measures across countries and birth cohorts and use twin comparisons to separate genetic from social influences. They will examine how changes in access to schooling for different generations and for men versus women relate to dementia risk. The work analyzes existing longitudinal human data rather than testing new treatments or interventions.

Who could benefit from this research

Good fit: Adults from diverse countries and birth cohorts, especially older adults and participants in long-term twin or aging studies, best match the kinds of data this project uses.

Not a fit: People seeking immediate clinical treatments, children, or those not enrolled in the long-term cohorts are unlikely to receive direct benefit from this observational research.

Why it matters

Potential benefit: If successful, this work could reveal social and genetic contributors to dementia risk and guide policies or programs aimed at reducing that risk linked to educational inequality.

How similar studies have performed: Many prior studies have linked higher education to lower dementia risk, but using harmonized international twin data to examine changes across countries, generations, and sexes is a newer approach.
