What this research studies

If you take part, researchers will follow nearly 2,000 people from the Diabetes Prevention Program Outcomes Study to track memory and thinking changes over time. They will use blood tests that measure amyloid, tau, neurodegeneration, and inflammation, and a subgroup of about 650 people will get brain imaging for amyloid, cortical thickness, small vessel disease, white matter structure, and connectivity. The team will also consider sleep problems, depressive symptoms, and sociodemographic factors like race, sex, education, and literacy when looking at who develops mild cognitive impairment or dementia. The work aims to link biological, imaging, and social factors to the types of cognitive problems people experience.

Who could benefit from this research

Good fit: Adults with a history of prediabetes or type 2 diabetes—especially those who were part of the DPPOS cohort—are the focus of this work.

Not a fit: People without prediabetes or type 2 diabetes or those not connected to the DPPOS cohort are unlikely to be directly involved or benefit from this specific project.

Why it matters

Potential benefit: If successful, this could help identify which people with prediabetes or type 2 diabetes are at higher risk of memory loss and point to targets for prevention or earlier care.

How similar studies have performed: Previous research has linked prediabetes and type 2 diabetes to higher dementia risk and shown promising biomarker signals, but combining blood biomarkers, detailed imaging, neuropathology, and social/behavioral factors in a single large cohort is less common.
