What this research studies

If you join, researchers will link high-resolution air pollution maps with molecular testing of blood, cerebrospinal fluid, and available brain tissue to see which pollution components are most harmful. They'll run multiple 'omics' tests (proteins, metabolites, and epigenetic markers) to find molecular fingerprints tied to those exposures. The team will compare these fingerprints with signs of Alzheimer's and related dementias to identify possible biological pathways. The work uses human samples and detailed exposure models to connect environmental toxicants with disease-related changes.

Who could benefit from this research

Good fit: Ideal candidates are people with Alzheimer's disease or related dementias, or those at higher risk who can provide blood or CSF samples and allow researchers to use their exposure and health data.

Not a fit: People who cannot provide biological samples or who lack reliable air-exposure data are unlikely to directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could reveal which pollution components raise dementia risk and point to biological markers for earlier detection or prevention.

How similar studies have performed: Earlier single-omics studies have shown pollution-related biological changes, but using integrated multi-omics to pinpoint specific toxic components is relatively new.
