Long‑lasting environmental poisons in veterans' brains tied to higher ALS risk
RFA-TS-24-010: Persistent Environmental Toxicants in Veteran CNS Tissue: Identifying Exposures Determining Higher ALS Risk
This project looks for persistent toxic chemicals in veterans' brain and spinal cord tissue that might explain why veterans develop ALS more often.

What this research studies
Researchers will examine donated brain and spinal cord tissue from U.S. veterans to measure long‑lasting toxicants linked to military exposures such as burn pits, engine exhaust, and firing ranges. They will use chemical and molecular analyses to identify metals, persistent organic pollutants, and other contaminants and compare levels between veterans who developed ALS and veterans who did not. By linking specific toxicant mixtures to ALS cases in veterans, the team aims to identify likely exposure sources and timing that raise risk. Results could point to targets for prevention, monitoring, and follow‑up clinical research.
Who could benefit from this research
Good fit: Ideal participants are U.S. veterans who can donate brain and/or spinal cord tissue after death, including veterans with ALS and control veterans without ALS for comparison.
Not a fit: People without military service or those unable or unwilling to participate in tissue donation are unlikely to directly benefit from this tissue‑based study in the short term.
Why it matters
Potential benefit: If successful, this work could identify specific exposures that raise ALS risk in veterans, helping to prevent future cases and guide monitoring or early detection.
How similar studies have performed: Previous research has linked certain environmental exposures to ALS risk, but directly measuring persistent toxicants in veteran CNS tissue is a relatively novel and less‑common approach.
