Established in 2012, the Vanderbilt Memory and Aging Project (VMAP) is a longitudinal study investigating vascular health and brain aging. VMAP was among the first studies to integrate imaging and fluid biomarkers to better understand how cardiovascular and cerebrovascular health affect brain health in older adults. Understanding the vascular contributions to the multiple pathways of Alzheimer's pathology offers investigators a chance to identify intervention targets much earlier in the disease process.
