| Purpose To review published evidence of possible links between Alzheimer’s disease (AD) and type-2 diabetes mellitus revealed by positron emission tomography (PET). Methods We searched online databases with keywords diabetes mellitus (DM), AD, and PET. We assessed the studies in terms of purpose, methodology, materials, and relationships between AD and DM suggested by PET imaging. Results After removal of 142 duplicates, 227 hits yielded no more than 15 full-length publications, from which we excluded six for specific reasons. The remaining nine studies were not directly comparable because of differences of purpose, study design, material, and methods. Individual subject materials consisted of 4–154 patients in case–control (4), observational (4), and longitudinal (1) studies, the last including only four DM patients. Mean patient age was 76.4 years (range 45–90). In five studies, researchers examined regional cerebral glucose metabolism with 18F-fluorodeoxyglucose (FDG), in three studies, researchers imaged amyloid with PET, and in one study, they measured both glucose metabolism and amyloid deposition. All four studies of amyloid tracers led to the conclusion that amyloid deposition was unaffected by DM status. Evidence of insulin resistance and increased blood glucose was associated with decreased FDG accumulation in AD signature regions in DM patients. Conclusion The relationships between DM and AD identified by PET appear to be independent of amyloid deposition and predominantly highlighted by reduced glucose metabolism, as suggested by four of the five glucose metabolism studies. |
