Summary

Numerous studies have provided evidence of a correlation between Type 2 Diabetes Mellitus (T2DM) and cognitive dysfunction, specifically in the realms of complex attention, information processing, and executive function. These impairments have been observed in middle-aged and elderly individuals with T2DM, with longer diabetes duration, suboptimal glycemic control, and the presence of diabetic complications being contributing factors. Recent research in young adults and adolescents diagnosed with T2DM has revealed cognitive and brain structural alterations in this growing demographic, suggesting that early disease mechanisms, rather than solely vascular and age-related neurodegeneration, contribute to pathogenesis. However, there remains uncertainty regarding the interplay between central and peripheral insulin resistance and its impact on cognitive dysfunction in individuals with T2DM. This study aims to investigate central insulin resistance in T2DM, elucidating its association with peripheral insulin resistance and the effects on cognitive impairments.

Conditions

Interventions

DRUG

160 units nasal insulin spray

Initially, a series of MRI scans, including high-resolution T1-weighted anatomical images, diffusion tensor imaging, resting-state functional MRI, and arterial spin labeling, will be conducted. Subsequently, 160 units of nasal insulin spray will be administered, followed by a second round of MRI scans after a 30-minute interval, encompassing high-resolution T1-weighted anatomical images, resting-state functional MRI, and arterial spin labeling.
