Alterations in cerebral metabolism and function have been suggested in type 2 diabetes, particularly in aging. To characterize metabolic abnormalities in the brains with type 2 diabetes, a rodent model for type 2 diabetes (dbdb) was studied in hippocampus and striatum using localized ultra-short echo time 1H MRS. Brain glucose levels were over twofold higher in diabetic mouse, As compared with those in control mice. The dbdb mice also showed significant increases in the levels of ascorbate, myo-inositol and taurine, suggesting alterations in antioxidant defense and osmoregulation. NAA was lower in the dbdb mice, which may indicate neuronal loss and is consistent with findings in diabetic patients.
