The era of sport concussion: Evolution of knowledge, practice, and the role of psychology.

The topic of sport concussion has gained significant prominence over the last 20 years, resulting in dramatic growth in research funding, widespread media coverage, and increased public awareness. Although the knowledge base has greatly expanded, there is still much that is unknown or controversial about the long-term effects of sports-related head injury. Because of the high stakes of mismanaging these injuries, professional sports organizations, federal/state government, and various health-related disciplines have responded with efforts to educate the public and improve treatment and management of this injury.
