← Human Body & HealthA football player sustains a diffuse axonal injury during a game. Which metabolic shift primarily explains the prolonged cognitive dysfunction following the initial impact?
A)Elevated cerebral blood flow
B)Increased ATP production efficiency
C)Impaired mitochondrial energy production✓
D)Enhanced neuronal glutamate reuptake
💡 Explanation
Impaired mitochondrial energy production causes a metabolic crisis following diffuse axonal injury because damaged axons struggle to maintain ion gradients. This leads to neuronal dysfunction and cognitive deficits; therefore, energy impairment explains prolonged dysfunction, rather than increased blood flow or efficient glutamate reuptake.
