Prenatal chemical exposures linked to midlife thinking and early Alzheimer's signs
Association of the in Utero Exposome with Life-Course Cognition and Prodromal Alzheimer's Disease in Midlife.
This project will look at whether chemical and other exposures during pregnancy are tied to thinking problems and early Alzheimer's-related changes in adults followed since birth.

What this research studies
If you take part, researchers will use stored prenatal and maternal samples plus current blood tests to connect in‑utero exposures with midlife thinking and early Alzheimer's-related blood markers. Participants will complete cognitive testing and provide blood for detailed metabolomics and biomarker analyses. The work follows about 400 people from a 50+ year birth cohort who were seen in childhood and adolescence and are being re‑examined in midlife. Scientists will focus on metabolic pathways already linked to brain aging, such as glutathione, methionine/cysteine, pyrimidine, and energy metabolism, to find actionable prevention targets.
Who could benefit from this research
Good fit: Ideal participants are adults from the Child Health and Development Studies birth cohort who can attend midlife exams and provide blood and cognitive testing, typically those around midlife with available prenatal records.
Not a fit: People without prenatal records or those already living with advanced symptomatic Alzheimer's are unlikely to get direct benefit from this observational biomarker work.
Why it matters
Potential benefit: If successful, this could reveal blood markers and biological pathways in midlife that point to earlier prevention or intervention strategies to lower Alzheimer's risk.
How similar studies have performed: Previous work links metabolomic changes and glutathione‑related pathways to cognitive decline, but using prenatal exposures to predict midlife Alzheimer's risk is a newer, less tested approach.
