What this research studies

You would be represented by long-term health and cognitive data from people who were followed from middle age into their 80s and 90s. Researchers will combine multiple cohort studies so there are enough people who reached age 90 without dementia to compare with those who developed dementia. They will examine past medical history, genetics (for example APOE), brain markers such as Aβ-42, vascular and lifestyle risks, and other health measures to look for patterns of risk and resilience. The work pools existing clinical records and biological measures rather than testing new treatments.

Who could benefit from this research

Good fit: Ideal participants are older adults (especially people aged 85 or older) who have long-term medical, cognitive, or biological data available or who are enrolled in one of the contributing cohort studies.

Not a fit: People without long-term follow-up data or biological samples, and those seeking immediate treatment options, are unlikely to get direct benefit from this project.

Why it matters

Potential benefit: If successful, this research could reveal factors and biomarkers that help prevent or delay dementia in very old adults.

How similar studies have performed: Previous pooled cohort efforts have successfully identified Alzheimer and vascular risk factors, but focusing on resilience and cognitive health specifically in the nonagenarian population is less commonly studied and relatively novel.
