← Human Body & HealthIf a football player's head experiences significant rotational acceleration during a tackle, which consequence follows, increasing the likelihood of persistent post-concussive symptoms?
A)Decreased cerebral blood flow
B)Focal contusions from direct impact
C)Reduced glutamate excitotoxicity threshold
D)Diffuse axonal injury due to shear strain✓
💡 Explanation
Diffuse axonal injury results from rotational acceleration causing shear strain within brain tissue, because axons stretch and tear, disrupting neural networks. Therefore, DAI is the likely outcome, rather than focal contusions or excitotoxicity which would present with different symptoms.
