What this trial studies

This observational study investigates the relationship between fluctuations in glucose levels and cognitive function in individuals aged 50 and older who are at risk for diabetes. Participants will wear a continuous glucose monitoring device for 10 days while their cognitive and functional status is assessed through two study visits. The study aims to determine if glucose variability is linked to cognitive decline and functional impairment before the onset of diabetes. By utilizing advanced monitoring technology, the researchers hope to uncover important insights into the effects of glucose on neurocognition.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50 years and older with prediabetes who do not have a diagnosis of diabetes.

Not a fit: Patients with diagnosed type 1 or type 2 diabetes or those with significant chronic or neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of cognitive decline in individuals with prediabetes.

How similar studies have performed: While the relationship between glucose levels and cognitive function has been explored, this specific approach using continuous glucose monitoring in prediabetic individuals is relatively novel.
