What this research studies

We are exploring if small metal particles in the air can enter the brain through the nose and lead to changes linked to dementia. Our team will examine brain tissues from participants in the Adult Changes in Thought (ACT) program who have generously donated their brains for research. We will also use long-term health information from thousands of ACT participants to see if exposure to these airborne particles is connected to developing dementia over time. This work aims to uncover new ways that our environment might impact brain aging and memory.

Who could benefit from this research

Good fit: This project uses existing data and donated brain tissue from older adults who participated in the Adult Changes in Thought (ACT) study.

Not a fit: Patients not enrolled in the Adult Changes in Thought (ACT) study would not directly participate in this specific research.

Why it matters

Potential benefit: If successful, this work could help us understand environmental risk factors for dementia, potentially leading to new strategies for prevention.

How similar studies have performed: While the link between air pollution and dementia is an active area of research, this project uniquely focuses on specific metal particles and their entry pathways into the brain.
