If an athlete sustains a concussion with suspected diffuse axonal injury, why does the initial assessment prioritize cognitive rest over immediate vestibular rehabilitation?

💡 Explanation

The initial priority is to reduce cerebral metabolic demand because diffuse axonal injury causes widespread neuronal dysfunction and energy crisis. Reducing cognitive activity lowers metabolic needs, therefore, allowing the brain to recover rather than exacerbating energy deficits through vestibular stimulation.
