Brain aerobic glycolysis is stable during adulthood: Direct evidence from cross-brain blood sampling in 239 healthy adults

Abstract The brain is a highly metabolic organ primarily fueled by glucose, and it is well established that a decline in cerebral glucose metabolism accompanies neurodegenerative disease. Recent work using positron emission tomography (PET) has demonstrated that cerebral glucose metabolism is also reduced in healthy aging which commences as early as 20 years of age, driven almost exclusively by reductions in non-oxidative glucose metabolism, that is, aerobic glycolysis.

Brain glucose extraction is fixed at 10% despite twofold variability in resting cerebral blood flow in healthy humans

|
By Jennifer Duffy, Hannah Caldwell, Ryan L. Hoiland, Connor Howe
| SAGE Publishing
Abstract In the resting, non-stimulated brain, metabolic demands are met exclusively by the delivery and extraction of glucose and oxygen at an ~6:1 ratio. Amongst healthy people at rest, there is marked variability in resting global cerebral blood flow (CBF) yet remarkably stable concentrations of circulating glucose and oxygen. Thus, we would expect interindividual variability in resting CBF to be inversely related to oxygen and glucose extraction, maintaining oxidative glucose metabolism.
