How age-related immune changes and social factors relate to dementia risk

Immunosenescence, socioeconomic differences and dementia in the US aging population

NIH-funded research University of Michigan at Ann Arbor · NIH-11232284

What this research studies

You would be part of a national effort that follows older adults over time to see how immune system aging (peripheral immunosenescence) relates to thinking problems and dementia. The team measures immune markers in blood, collects information about socioeconomic and social factors, and gives standardized cognitive tests across multiple visits. Because the project uses a nationally representative sample, it aims to show whether immune changes predict future decline and whether social factors change that risk. Findings come from linking biological samples, cognitive testing, and health records to diagnose Alzheimer’s and related dementias.

Who could benefit from this research

Good fit: Ideal candidates are U.S. older adults willing to provide blood samples, complete cognitive testing and health questionnaires, and take part in follow-up visits.

Not a fit: People seeking immediate treatment for dementia or those not included in the study’s sampling frame (for example, younger adults or those unwilling to provide blood samples) are unlikely to receive direct benefit from participation.

Why it matters

Potential benefit: If successful, this work could identify immune signals and social factors that help find people at higher risk for dementia earlier and guide prevention or tailored care.

How similar studies have performed: Previous studies have linked immune-aging markers to cognitive decline, but long-term, nationally representative evidence connecting peripheral immunosenescence to new dementia cases is limited.
