Blood vessels in the brain and the immune cells circulating through them may both help set the stage for dementia, but how they interact is unclear. A vascular contribution to Alzheimer's disease has been discussed since the 1960s, yet it is hard to pin down because cerebrovascular disease, damage to brain blood vessels, so often coexists with Alzheimer's pathology.

What they work on

  1. Test whether circulating markers of vascular and immune dysfunction, including platelet aggregation, neutrophil activity and blood proteomic profiles, are associated with MRI measures of cerebrovascular burden in the Framingham Heart Study and the cardiovascular-risk-enriched ARISE-DP cohort.
  2. Relate these platelet, neutrophil and proteomic markers to PET imaging of amyloid and tau deposits, and test whether cerebrovascular burden and amyloid positivity interact in shaping Alzheimer's pathology.
  3. Determine whether baseline vascular and inflammatory markers predict later cognitive decline and progression of blood Alzheimer's biomarkers, specifically the phosphorylated tau forms p-tau181 and p-tau217.
  4. Integrate biofluid and imaging data across both cohorts to identify candidate biological mediators linking vascular and immune dysfunction to dementia progression.

More about the research

Recent work suggests that vessel dysfunction and inflammation may act together to push the disease forward.

Why it matters

Alzheimer's disease and related dementias still have unclear biological causes and few disease-modifying treatments. Linking easily measured blood markers of clotting and inflammation to brain imaging and later cognitive decline could reveal new mediators and therapeutic targets, and may help identify people at risk, including those in populations with a high prevalence of cardiovascular risk factors who are often underrepresented in dementia research.
