How blood tests and risk factors differ by sex for Alzheimer's and related dementias
Sex-specific risk factors and trajectories of blood biomarkers for Alzheimer's disease and related dementias
This project looks at blood tests (amyloid, tau, and neurodegeneration markers) and other risk factors in older men and women to help spot who may develop Alzheimer's or related dementias.

What this research studies
If you join, researchers will follow older adults without dementia over time, taking regular blood samples to measure amyloid, tau, and neurodegeneration (AT(N)) markers and tracking health, lifestyle, and medical conditions. They will compare how these blood markers change over time in men versus women and how other conditions like heart disease or alcohol use affect interpretation. The team will use this information to build the first sex-specific risk score that combines blood AT(N) biomarkers with known dementia risk factors. That score could help doctors give more personalized prognosis and prevention plans in the future.
Who could benefit from this research
Good fit: Ideal candidates are community-dwelling older adults without a dementia diagnosis who can give blood samples and attend follow-up visits, including both men and women.
Not a fit: People already diagnosed with dementia, those unable to provide blood samples, or those unwilling to attend follow-up visits are unlikely to benefit directly from this work.
Why it matters
Potential benefit: Could lead to sex-tailored blood tests and risk scores that help predict dementia earlier and guide personalized prevention.
How similar studies have performed: Blood amyloid and tau markers have shown promise in research settings, but combining them with sex-specific risk scores in large community studies is a newer approach.
