While issuing concussion guidelines, the ICC defined it as "a ‘traumatic brain injury induced by biomechanical forces’. It typically results in a rapid onset of neurological impairment that resolves spontaneously, although in some cases, clinical features may evolve over time. A concussion does not cause any structural damage to the brain, but acute clinical signs and symptoms largely reflect functional disturbance. Nevertheless, concussion is a potentially serious injury that may have both short (increased musculoskeletal and brain injury risk) and long-term (CTE, dementia and mental health issues) health risks. Concussion, therefore, requires a conservative management approach. "
