Sports Concussions: A Webliography

Abstract A concussion is a type of brain injury caused by a direct or indirect blow to the head or body causing the brain to move rapidly within the skull, resulting in immediate, but temporary, brain dysfunction. Concussions can happen when playing sports, during recreation, because of a fall or accident, or from an act of violence. Every year, approximately 42 million people worldwide, including at least 3 million in the United States, suffer from concussion, making it a public health issue. Persons of all ages, from the youngest children to the most aged adults, and from all walks of life can be affected by concussion. Identifying and understanding the best evidence for prevention and treatment of concussion can be challenging due to the vast amount of information available on the Internet.
