Document Summary
Concussion is a common injury that emergency medicine physicians will be called upon to evaluate. A comprehensive history and physical examination, cognitive evaluation, and balance testing are important in the assessment of a head injury. Athletes should never be allowed to return to play on the same day they suffer a concussion. Concussion is a form of mild traumatic brain injury (tbi) that results when a direct blow to the head, neck, face or elsewhere on the body produces biomechanical forces that are subsequently transmitted to the brain. It usually result in rapid onset of signs, symptoms, and neurologic impairment, which typically resolve spontaneously. The pathophysiology is not completely understoof, but it is thought to be a functional disturbance that is due to a complex metabolic cascade that occurs within the brain as a result of trauma. Typically, no structural disturbance can be visualized on advanced imaging.
