Brief Summary:
This is a cross-sectional and longitudinal study to investigate the relationship and central mechanism between type 2 diabetes and cognitive impairment based on the simultaneous EEG-fMRI approach and peripheral neuropathology biomarkers assay.
Detailed Description:
Little is known about the high risks of cognitive impairment and Alzheimer's Disease (AD) in people with type 2 diabetes. The goal of this study is to characterize brain imaging biomarkers of preclinical AD and related cognitive impairment in people with type 2 diabetes using the simultaneous EEG-fMRI approach and peripheral neuropathology biomarkers assay. We will recruit 400 patients with type 2 diabetes in the outpatient and inpatient departments. Each subject will undergo simultaneous EEG-fMRI scan, classical multimodal MRI scan, cognitive assessments and peripheral neuropathology biomarkers assay at the baseline. This study will qualify gray matter volume, cortical thickness, gray matter and white matter microstructure, cerebral blood flow, spectrum changes, as well as resting state and dynamic functional network connectivity from the imaging examination. Study duration was 3 years with a follow-up every 12 months. Cognitive assessments and imaging scan will be conducted in each follow-up visits. At the end of the study, all of the assessments will be performed again for all recruited subjects.
