Family-based search for genes that protect against Alzheimer's and support healthy aging

Project 1

NIH-funded research Washington University · NIH-11096296

This project looks for rare family-linked genetic changes that help people stay mentally sharp and resist Alzheimer's, focusing on families with many long-lived members.

What this research studies

Researchers follow families with many long-lived members and collect detailed health, cognitive, and lifestyle information at in-person visits over years. They perform whole-genome sequencing and family-based linkage analyses to find rare protective genetic variants that appear in pedigrees with exceptional cognition or resilience to Alzheimer's disease. The project includes offspring and grandchildren enrolled in the Long Life Family Study and links participant records to medical registries to track health outcomes over time. Results are used to identify biological pathways that could inform future prevention strategies or therapies for age-related cognitive decline.

Who could benefit from this research

Good fit: Ideal participants are people from families with multiple long-lived relatives (offspring or grandchildren of LLFS pedigrees) who can provide health information and a DNA sample.

Not a fit: People without a family history of exceptional longevity or those seeking immediate clinical treatments are unlikely to gain direct medical benefit from this genetic discovery-focused research.

Why it matters

Potential benefit: Identifying protective genetic factors could point to new ways to prevent Alzheimer's or develop treatments that mimic those protective effects.

How similar studies have performed: Previous Long Life Family Study publications and other family-based genetics projects have found rare variants linked to healthy aging and cognitive resilience, though turning discoveries into therapies remains early-stage.
