Fasting brain glucose

Fasting brain glucose predicts gray matter volume in humans.

“brain glucose, but not blood glucose, independently predicts gray matter loss and partially mediates age-related atrophy”

Higher fasting brain glucose is associated with lower gray matter volume in healthy adults

Age is associated with fasting brain glucose in humans.

“cerebral glucose remains stable until older age (60-80 years) before increasing.”
