What this research studies

We want to understand why some people develop Alzheimer's disease and related dementias, while others with similar genetic risks do not. This project looks at how long-lasting effects from environmental toxins might interact with a person's genes to cause these brain conditions. We will collect blood samples from siblings in northern Indiana who have different brain health outcomes, then turn these blood cells into brain cells in the lab to study their vulnerability. This helps us see how genetic and environmental factors might lead to neurodegenerative diseases.

Who could benefit from this research

Good fit: Ideal participants for related efforts would be same-sex siblings in northern Indiana who show differences in their cognitive and motor function related to Alzheimer's or Parkinson's disease.

Not a fit: Patients not directly involved in providing samples for this foundational laboratory research may not experience immediate personal benefit.

Why it matters

Potential benefit: If successful, this work could lead to a better understanding of how to prevent or treat Alzheimer's disease and related dementias by identifying key gene-environment interactions.

How similar studies have performed: While genetic risk factors for Alzheimer's have been identified, this specific approach of studying gene-environment interactions using patient-derived stem cells from siblings is a novel way to explore persistent neurotoxicity.
