Sport-related concussion is a traumatic brain injury caused by biomechanical forces (direct blow to the head or elsewhere on the body with forces transmitted to the head). It results in a functional disturbance, rather than a structural injury. Therefore, standard brain imaging tests (i.e., CT and MRI) show no abnormality. Symptoms are usually rapid in onset, but may take minutes to hours to develop. Loss of consciousness may or may not occur. Rarely are there external signs of head trauma.
Sport-related concussion should be suspected if any of the following symptoms are present.
If sport-related concussion is suspected, it is generally recommended to rest, avoid use of electronics, drink plenty of fluids, and eat a healthy diet. It is imperative to be seen by a specialist to confirm the diagnosis of sport-related concussion, evaluate for the presence of other injuries, and to receive proper treatment for your particular condition(s).
Seek emergency care if the following symptoms are present or if you have any urgent concerns.
