A Study to Assess Glycemic Variability and Fluctuations in Cognitive Status in Adults with Type 1 Diabetes


About this study

The objective for thisstudy is to characterize the impact of glycemic excursions on cognition in Type 1 Diabetes (T1D) and determine mediators and moderators of this relationship. This study will allow us to determine how glycemic excursions impact cognition, as well as to identify mediators and moderators of this relationship that could lead to novel interventions.
