How everyday chemical exposures may change Alzheimer's and its course
The Role of Chemical Exposures in Alzheimer's Disease (AD) and its Trajectory
This project looks at how chemicals in the environment, diet, and the gut interact with genes and blood chemistry to relate to Alzheimer's for people with or at risk for the disease.

What this research studies
If you join, you would contribute blood, stool, and health information so researchers can link chemical exposures, the gut microbiome, and metabolic changes to brain scans and memory changes. The team combines advanced metabolomics and lipidomics with genetic data and neuroimaging from partnerships like ADNI and several Alzheimer Research Centers. They also work with large diet and lifestyle programs to see how those factors shape the gut-brain connection. All this data will be used to build a molecular atlas that maps how exposures affect Alzheimer's over time.
Who could benefit from this research
Good fit: Ideal candidates are older adults with Alzheimer's disease, mild cognitive impairment, or those at elevated risk who can provide biological samples and medical information at participating centers.
Not a fit: People without concerns about cognitive decline, those with non-Alzheimer's brain diseases unrelated to the study goals, or individuals unable to provide samples or travel to partner sites are unlikely to benefit directly.
Why it matters
Potential benefit: If successful, this work could lead to better blood-based markers to detect Alzheimer-related changes earlier and suggest new ways to lower risk by changing diet, exposures, or microbiome factors.
How similar studies have performed: Previous efforts like ADNI and earlier metabolomics work have found links between blood metabolites, the gut microbiome, and brain changes, but combining exposome data and a multi-center molecular atlas is a newer, more comprehensive approach.
