About

This study examines the association of variability in glucose values over a 10-day period with cognitive function and functional status among individuals with prediabetes, aged 50 or older.

Full description

Type 2 diabetes (T2DM) is now widely considered a major public health epidemic. T2DM is highly prevalent worldwide, is among the leading causes of death, and is an independent risk factor for dementia and less severe forms of cognitive dysfunction. The investigators are utilizing novel technology to understand the role of variability in glucose on neurocognition and functional status among middle-aged and older adults at risk for diabetes. The central hypothesis is that even before diabetes onset, variability in glucose will be associated with worse cognitive function and lower functional status. Participants will be asked to wear a glucose monitoring device over a 10-day period in their home environment. Assessment of functional status and neurocognitive function, in addition to sociodemographic factors, health habits and mood will also occur over two study visits.
