Traumatic brain injury is the leading cause of death and disability in the world for adolescents according to the World Health Organization. Sports-related concussion is a small but perhaps one of the most preventable causes of that morbidity. Legislation to protect student athletes is one of the ways in which we can advocate for safety in sports. ⋯ This history is viewed from the point of view of one of the participants in the efforts to pass laws in all 50 states. The key provisions of the Zackery Lystedt Law include (1) education for parents, athletes, and coaches; (2) immediate removal from play during a game or practice, after a suspected concussion with no return to play until (3); (3) written clearance by a concussion expert for return to play; and (4) uniformity of rules for all schools who use public land. Last, the nature of this legislative process, which included attorneys, legislators, and physicians, demonstrated that effective collaboration of local, state, and national leaders can address a critical public health challenge such as concussion affecting student athletes.

At least 300 000 sports-related concussions occur in the United States annually. With millions of American athletes, the long-term effects of repeated concussion or mild traumatic brain injury are an important topic. Unfortunately, there is a lack of strong data on the causality or prevalence of long-term effects among athletes. ⋯ Concern exists that athletes subject to repeated concussive and even subconcussive blows may be at risk of CTE, but no definitive data exist due to the difficulty in diagnosis. Animal models suggest that mild traumatic brain injuries lead to primarily a metabolic derangement with increased excitotoxic neurotransmitter release, extracellular potassium, and intracellular calcium. Further understanding of the underlying pathophysiology may eventually lead to better therapeutic and diagnostic options for the treating clinician.

Roger Goodell was invited by the Neurosurgical Society of America (NSA) to give the keynote speech as the NSA Medalist 2013. As President of the NSA, and Co-Chairs of the National Football league's Head Neck and Spine Committee, we provided the introduction for Goodell. ⋯ Mr Goodell's national leadership in thinking and acting boldly on the subject of traumatic brain injury prevention and treatment was the primary motivation for awarding him the NSA medal. What follows is a transcript of his NSA Medal Lecture to the Neurosurgical Society of America.

Individually, immunomodulatory therapy and chondroitinases have demonstrated neuroprotective and potential neuroregenerative effects following spinal cord injury. ⋯ The present data suggest that delivery of an immunomodulatory therapy consisting of clodronate and rolipram, in combination with ChABC, reduces axonal injury and enhances neuroprotection, plasticity, and hindlimb functional recovery after hemisection spinal cord injury in adult rats.
