Evaluation of brain redox status and its association with cognitive dysfunction in diabetic animal models by redox molecular imaging (ReMI)

Oxidative stress contributes to the development of diabetic complications. Increasing epidemiologic evidence suggests that diabetes mellitus is associated with dementia and cognitive decline. However, the underlying mechanisms are not fully understood. We have evaluated brain redox status and its association of cognitive dysfunction in diabetic animal models by dynamic nuclear polarization-magnetic resonance imaging (DNP-MRI) and other oxidative stress markers. In this review, we discuss the role of oxidative stress in the development of diabetes-related dementia and clinical regulation of the redox state in new approaches to augmenting diabetes-related dementia.
