An intricate relationship normally exists between cerebral metabolism and energy substrate supply because of the brain's high substrate demand and limited storage capacity. In head-injured patients, this balance can be disrupted. The brain parenchyma directly involved by the injury is hypometabolic in respect to glucose and oxygen, whereas peri-injury tissue may have an elevated metabolic rate.
