How aging eyes relate to Alzheimer’s and brain aging

Aging eyes and aging brains in studying alzheimer''s disease: Modern ophthalmic data collection in the adult changes in thought (ACT) study

NIH-funded research Washington University · NIH-11419893

We will collect non-invasive eye tests and retinal images from older adults in the ACT cohort to learn how changes in the eye relate to Alzheimer's and other dementias.

What this research studies

You would have gentle, non-invasive vision tests and retinal photos taken and allow researchers to link those results with decades of your ACT study records, cognitive testing, and available autopsy data. The project combines new eye imaging and visual function measures with extensive past eye clinical data from the long-running ACT cohort. The team is expanding the eye-focused group as the parent ACT cohort grows, and they are especially looking at blood vessel disease and vision loss as possible links to dementia. Your participation would help researchers look for eye signs that might predict or reflect brain changes related to Alzheimer’s.

Who could benefit from this research

Good fit: Older adults who are part of (or eligible for) the ACT cohort, able to attend Washington University study visits, and willing to have non-invasive eye testing and retinal imaging are the ideal candidates.

Not a fit: People seeking immediate treatment or those with advanced dementia should not expect direct medical benefit from participating in this observational research.

Why it matters

Potential benefit: If successful, this work could help doctors use simple eye exams or images to detect Alzheimer’s risk earlier and better understand vision-related contributions to dementia.

How similar studies have performed: Smaller prior studies have reported links between retinal changes and dementia risk, but this large, long-term cohort with extensive autopsy data aims to provide more definitive evidence.
