Details and patient eligibility

About

The purpose of this study is to determine if improving diabetes control by better controlling blood sugars, will help improve or normalize brain function as compared to routine diabetes care. We will use either the patient's own insulin routine (injections or insulin pumps) or a closed-loop insulin pump (Medtronic 670G). This system uses a continuous glucose monitor (CGM) and an insulin pump to automatically give insulin and may improve control of blood sugars.

46 participants in 2 patient groups

Standard Care
Active Comparator group
Description:
Subjects will continue on their current treatment (insulin pump or injections), with follow up every 3 months. Neurocognitive testing and brain MRI/fMRI will be done at enrollment and 6 months.
Treatment:
Other: Standard Care
Closed-Loop
Active Comparator group
Description:
Subjects will transition from their current treatment (insulin pump or injections) onto the Medtronic 670G insulin pump (intervention arm as a comparator) and will have close contact with the study team. Neurocognitive testing and brain MRI/fMRI will be done at enrollment and 6 months.
