Postdoctoral Grant
Exploration of Longitudinal Changes in Gut Microbiome Composition Stratified by Amyloid Status
Outcome Report

2024
Alzheimer’s disease (AD) affects over 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 analyzed longitudinal fecal samples and fluid biomarkers from participants in the Wisconsin Registry for Alzheimer’s Prevention and the Alzheimer’s Disease Research Center. Results showed an increase in potentially pathogenic taxa alongside a decrease in beneficial microbes in amyloid-positive individuals compared to amyloid-negative individuals. This work contributes to understanding early biological processes that may influence later disease risk and has the potential to inform future prevention and intervention strategies.
