Concussion has been in the medical lexicon since Hippocrates,1 and widespread viewing of sports concussion is now commonplace. This mildest form of traumatic brain injury (TBI) has obvious acute effects, but motor symptoms seem to abate quickly as the concussed player leaves the contest. The prompt return to baseline in most sports concussions could be considered as evidence for the transient nature of the injury, with the brain's homeostatic equilibrium temporarily disrupted and then restored, but this view may be changing. With 1.6–3.8 million sports-related concussions annually in the United States (http://www.cdc.gov/ncipc/tbi/Physician_Tool_Kit), the possible long-term consequences of concussion clearly merit attention.
