Sports Related Concussion
Key Points
Concussion involves transient, traumatic brain dysfunction; consciousness may be lost, but sometimes patients manifest only confusion, memory loss, and gait or balance difficulties. Symptoms may resolve quickly or persist for up to several weeks. Athletes with possible concussion should be removed from play and evaluated; screening tools such as SCAT3 or SCAT5 may be helpful. Neuroimaging is done if there is loss of consciousness, GCS < 15, focal neurologic deficits, persistently altered mental status, or clinical deterioration. After concussion, patients are more susceptible to repeat concussion for a period of time and must refrain from sports activities until they have been asymptomatic for 1 week or more (depending on severity of injury). Athletic activities are resumed gradually.
