Gut microbiome and brain health in Puerto Ricans with Alzheimer’s risk

Official title: Microbiome Multi-Omics and Cognitive Decline in Latinos

Funded at University of Massachusetts Lowell · NIH-11463268 · Data updated 2026-11-12

We’re studying how the gut microbiome may influence cognitive aging and Alzheimer’s risk in Puerto Ricans aged 21 and older.

Who could benefit from this research

Could help

Adults 21 and older, particularly US-based Puerto Ricans who may be at higher risk for Alzheimer’s disease and cognitive decline.

Less likely to help

Individuals without access to or participation in the BPRHS cohort or without measurable gut microbiome or cognitive data may not directly benefit.

What this research studies

This project will explore how gut bacteria and their multi-omics signals relate to cognitive decline using the Boston Puerto Rican Health Study cohort. By combining microbiome data with brain imaging and cognitive assessments, researchers aim to identify patterns that link gut health to memory and thinking changes in a minority population. The study plans to map these relationships over time to better understand why Puerto Ricans have higher Alzheimer’s risk and how this risk might be mitigated. If successful, findings could guide future prevention strategies and personalized interventions that consider gut health and cultural context.

Why it matters

Potential benefit: Better understanding of why a high-risk group experiences cognitive decline could lead to targeted prevention and treatment approaches.

How similar studies have gone: This is among the largest studies in a minority population investigating gut microbiome in relation to cognition, building on prior smaller studies.
