Glucose uptake and metabolism has been shown to be impaired during Alzheimers disease and is suggested to be an important cause of neurodegeneration. However the cause of impairment of glucose uptake/metabolism is AD brain and its correlation with plaque deposition is not clear. In this study, we longitudinally monitored, the change in glucose level in APPTG2576 mouse model of AD using in vivo MRS in conjunction with MRI and ex vivo HR-MAS ¹H MRS. Our results indicate that decline in glucose level occur primarily in plaque affected areas of the brain of APPTG2576 mice and show a temporal correlation between glucose decline and plaque deposition in AD brain.
