Investigating the Insulin Resistance in Individuals With Type 2 Diabetes

Status Not yet recruiting

Clinical Trial 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.

Clinical Trial Description

Participants screened through inclusion and exclusion criteria will accept cross-sectional evaluation. The information of demographic data, medical history, previous and current medication regimen, details of complications, and family history regarding metabolic diseases will be collected. The assessments includes physical examination, anthropometry, blood test(blood routine, liver function, renal function, blood lipids, fasting blood glucose, serum insulin，thyroid function and glycosylated hemoglobin A 1c), MRI scan( High-resolution T1-weighted Anatomical Images, Diffusion Tensor Imaging, Resting-state functional MRI and Arterial Spin Labeling) and psychiatry scales(Hamilton Depression Scale, Young Mania Rating Scale and Self-reporting Inventory-90); cognitive function will be assessed by the Measurement and Treatment Research to Improve Cognition in Schizophrenia(MATRICS) Consensus Cognitive Battery; biological samples also will be collected and stored to explore related mechanisms. ;
