Understanding brain fluid spaces in aging and Alzheimer's disease

Structural and diffusion changes of perivascular space in aging, cognitive decline and Alzheimer's disease

NIH-funded research University of Southern California · NIH-11134722

What this research studies

Our brains have tiny spaces around blood vessels, called perivascular spaces, which are important for clearing waste. While animal studies have shown how these spaces work, we need to learn more about them in humans. This project uses advanced MRI scans to map the size and fluid movement within these spaces in healthy older adults and those with early Alzheimer's disease. We believe these characteristics will be different in people experiencing cognitive decline, offering new insights into Alzheimer's disease.

Who could benefit from this research

Good fit: Ideal candidates for future related studies might include healthy older adults and individuals in the early stages of cognitive decline or Alzheimer's disease.

Not a fit: Patients with advanced Alzheimer's disease or other neurological conditions not related to perivascular space changes may not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could help us better understand the early stages of Alzheimer's disease and potentially lead to new ways to detect or treat it.

How similar studies have performed: While animal studies have clarified how these brain spaces work, this project aims to develop more precise ways to map them in humans, which is a relatively new approach.
