Put a bunch of football players on the gridiron, and sooner or later someone will receive a concussion. What happens next—treatment and recovery—remains an inexact science.

Diagnosis, treatment, and rehabilitation protocols remain in question because of a lack of rigorous trial data. Among the basic issues still unresolved are how to define concussion.
