Brief Summary:
Alzheimer's disease (AD) is closely related to diabetes (DM). DM will aggravate the progression of AD, but the specific mechanism has not yet been clarified. Previous study found that a key pathological feature of the pancreas in patients with DM is islet amyloid polypeptide, and there is also islet amyloid polypeptide in the brain. Therefore, DM may cause cytotoxicity through the interaction between pancreatic amyloid and brain Aβ protein and further aggravate AD progress. In this study, starting with DM and AD pathological biomarkers, the amyloid PET target molecular probe 18F-AV45 will be used to monitor the dynamic changes of amyloid protein in the brain and pancreas during the development of AD. The completion of this study will provide a new view for understanding the mechanism of DM on AD cognitive dysfunction and effectively preventing and treating these two diseases.
Detailed Description:
This is a single-center, prospective, and observational study, which mainly focuses on the interaction between pancreatic amyloid and brain Aβ protein and further aggravates AD progress in China. PET imaging will be used on subjects. Previously collected patient data may also be enrolled in this study.
