If a football player suffers a concussion with widespread axonal injury from diffuse shear strain during a game, which intervention is most critical in the immediate post-impact phase?

💡 Explanation

Strict cognitive and physical rest is vital because diffuse axonal injury results in a metabolic crisis; therefore, reducing energy demands aids neuronal recovery, rather than exacerbating metabolic stress with activity or using treatments irrelevant to concussion pathophysiology.
