The Hisayama study, Diabetes care, 10.2337/dc15-2800, 39, 9, 1543-1549, 2016.09, OBJECTIVE To investigate the association between diabetes and brain or hippocampal atrophy in an elderly population. RESEARCH DESIGN AND METHODS A total of 1,238 community-dwelling Japanese subjects aged ≥65 years underwent brain MRI scans and a comprehensive health examination in 2012. Total brain volume (TBV), intracranial volume (ICV), and hippocampal volume (HV) were measured using MRI scans for each subject. We examined the associations between diabetes-related parameters and the ratios of TBV to ICV (an indicator of global brain atrophy), HV to ICV (an indicator of hippocampal atrophy), and HV to TBV (an indicator of hippocampal atrophy beyond global brain atrophy) after adjustment for other potential confounders. RESULTS Themultivariable-adjustedmean values of the TBV-to-ICV,HV-to-ICV, and HV-to-TBV ratios were significantly lower in the subjects with diabetes compared with those without diabetes (77.6%vs. 78.2%for the TBV-to-ICV ratio, 0.513%vs. 0.529%for the HV-to-ICV ratio, and 0.660% vs. 0.676% for the HV-to-TBV ratio; all P
