Role of energy synthesis disorders in pathogenesis of Alzheimer' s disease / 中国药理学通报

ABSTRACT

Alzheimer's disease is a neurodegenerative disease with multiple causes. Due to no effective drugs to reverse the progress of AD, many researchers in the world focus on the early pathological changes of AD in order to find the effective intervention for delaying the progress of AD. As an organ with high energy demand, brain is very sensitive to changes in fuel supply and energy alteration. Abnormal glucose metabolism and mitochondrial dysfunction are the important signs of brain aging and the main causes of bioenergetic deficits, which appear earlier than the characteristic pathological injuries of AD. So the disturbance of energy synthesis has been considered an early contributory e- vent to AD progression. In this article we review the study progress of energy synthesis disorder involved in the pathogenesis of AD base on cerebral blood flow, glucose uptake, utilization and the relative metabolic regulation in the brain.
