Longitudinal Changes in Gut Microbiome Composition is Associated with Biofluid Markers of Alzheimer’s Disease
Awarded in
2024
Alzheimer’s disease (AD) affects more than 110,000 older adults in Wisconsin and remains without a cure. Emerging evidence suggests the gut microbiome may play a role in AD pathology, but how these changes unfold over time is not well understood. This project will analyze longitudinal fecal samples, fluid biomarkers and cognitive scores from participants in the Wisconsin Registry for Alzheimer’s Prevention (WRAP) and the Alzheimer’s Disease Research Center (ADRC). The study will test whether shifts in gut microbiome composition are linked to amyloid status, cognitive decline and AD biomarkers in plasma and cerebrospinal fluid. Findings are expected to identify specific gut microbes associated with AD progression, laying the groundwork for future therapeutic targets and larger multicenter studies.
