How metals and genetics affect brain aging and Alzheimer's disease

The impact of metals and polygenic risk on multiomics, brain aging, and ADRD outcomes

['FUNDING_U01'] · UNIVERSITY OF MICHIGAN AT ANN ARBOR · NIH-10954519

This study is looking at how exposure to harmful metals like lead and arsenic, along with our genes, might affect brain aging and the risk of developing Alzheimer's disease, using mice that reflect human genetic differences, and it hopes to find simple ways to check for brain changes through blood tests to help improve prevention and treatment for Alzheimer's.

What this research studies

This research investigates how exposure to toxic metals like lead, cadmium, and arsenic, along with genetic factors, influence brain aging and the development of Alzheimer's disease and related dementias. Using genetically diverse mouse models that better represent human genetic variability, the study aims to uncover the molecular and behavioral changes linked to these exposures. The research will also explore whether biomarkers in easily accessible tissues, such as blood, can indicate changes in the brain associated with these toxicants. By addressing significant gaps in our understanding of these relationships, the study seeks to inform prevention and treatment strategies for Alzheimer's disease.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals at risk for Alzheimer's disease or related dementias, particularly those with exposure to toxic metals.

Not a fit: Patients who do not have any risk factors for Alzheimer's disease or related dementias may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new insights into modifiable risk factors for Alzheimer's disease, potentially guiding prevention and treatment efforts.

How similar studies have performed: Other research has shown promising results in understanding the impact of environmental toxins on cognitive decline, suggesting that this approach could yield valuable insights.
