The Early Warning System for the Diabetic Encephalopathy

Condition(s) studied

Study summary

Diabetes( mainly type II diabetes )lead to the central nervous system (CNS) function impairment, especially the mild cognitive impairment that increased the risk of progression to dementia.The primary objectives are defined according to a hierarchical design: i) to tailor and apply multi-parametric, functional MRI techniques to identify cerebral abnormalities (cerebral biomarkers) in type 2 diabetes mellitus and prodromal diabetes mellitus ; ii) to assess whether these cerebral biomarkers are associated with cognitive decrements;iii) to follow up with the putative prediabetic condition patients to verify whether they can transform into diabetes.

Eligibility

Primary outcome measure(s)

• Functional and structural connectivity relationships of multiple brain regions and biomarkers of brain alterations, and the changes in relationships and biomarkers at 2.5 years. — subjects will be assessed six times (once half a year, up to 2.5 years )
  Differences in macro-structural and micro-structural between patients,prodromal group and healthy controls will be evaluated. These MRI measures include volumetric characteristics (e.g. hyper-intensities, white matter lesions, atrophy, cerebral microbleeds), quantitative measures (e.g. T2 relaxation times, mean diffusivity, fractional anisotropy, mean kurtosis), functional characteristics (e.g. activated regions, cerebral blood flow), network properties (e.g. functional and structural connectivity, graph-theoretical measures).
