Sport-Related Concussion

JAMA. 2018;319(8):840. doi:10.1001/jama.2018.0436

A concussion is a type of traumatic brain injury.

Concussion is caused by a strong impact to the head that leads to problems with thinking or other neurological symptoms. Concussions can occur in any sport when there is a blow to the head, neck, or body that sends a strong force to the head. The symptoms of concussion include headache, cognitive problems such as mental fogginess or changes in memory, problems with balance and coordination, behavioral changes such as irritability, and slowed reaction time. Although most concussions are not associated with loss of consciousness, temporary loss of consciousness can occur.
