Abstract
Concussion is a transitory brain injury resulting from a blow to the head. Concussion
is considered a mild traumatic brain injury (mTBI), which is self-limited. Repetitive
mTBI has been associated with chronic, progressive neurologic damage. Extreme biochemical
changes occur in neuron cells as a result of mTBI. These metabolic disturbances may
reflect the symptoms observed in patients who had concussions. However, it has been
difficult to match clinical signs and symptoms. Currently, there is no test to diagnose
concussion. Further studies are needed to elucidate the biochemical details of the
metabolic cascade and the associated time frame, which will help determine when an
athlete can safely return to the game.
