How education shapes dementia risk across countries, generations, and sexes

Differences in the association of education with ADRD across countries, historical eras, and men and women

NIH-funded research University of Southern California · NIH-11508132

What this research studies

You would be contributing information from long-term twin studies in the IGEMS consortium, where researchers compare education, jobs, and cognitive health across countries, birth years, and sexes. The team harmonizes education using international scoring (ISCED) and analyzes twin pairs to separate social influences from genetic ones. They also examine how these links changed for people born in different eras and between men and women, and include genetic risk measures when available. This work uses existing observational data rather than testing a clinical treatment.

Who could benefit from this research

Good fit: Adults (typically older adults) who are part of long-term cohort or twin studies and can share education and health history—especially twin pairs—across participating countries are the ideal candidates.

Not a fit: People seeking immediate clinical treatments for dementia or those under age 21 are unlikely to receive direct medical benefit from this observational research.

Why it matters

Potential benefit: If successful, the work could reveal social and genetic factors that protect against dementia and help target prevention efforts to groups who would benefit most.

How similar studies have performed: Previous research has consistently linked higher education to lower dementia risk, but this large international twin-consortium approach is relatively new and aims to separate social from genetic influences.
