Reversing brain glucose transport issues in Type 2 diabetes

What this trial studies

This clinical trial investigates the impact of high blood glucose levels on brain glucose transport in individuals with poorly controlled Type 2 diabetes mellitus (T2DM). It aims to determine if improvements in glucose control can reverse the observed abnormalities in brain glucose transport. Participants will undergo a screening visit, receive a continuous glucose monitor (CGM) for two weeks, and have two magnetic resonance spectroscopy (MRS) assessments at the start and after 12 weeks. The study also includes nutrition visits and intensification of diabetes management.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 with a medical history of Type 2 diabetes and an HbA1c greater than 7.5%.

Not a fit: Patients with uncontrolled hypertension, known neurological disorders, or those who cannot undergo MRI/MRS may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for brain health in patients with Type 2 diabetes.

How similar studies have performed: Other studies have shown promising results in improving glucose control and its effects on various health aspects, but this specific approach is relatively novel.
