Short Description or Definition

Mild traumatic brain injury (MTBI) is a trauma-induced alteration in neurological function caused by a direct blow to the head or from rapid acceleration, deceleration, rotational, or percussive forces on brain tissue. Common mechanisms associated with MTBI include a motor vehicle accident, fall, assault, or contact sports. The diagnosis of MTBI is made based on identifying an event with adequate force to cause a concussive injury and by examining acute injury indicators to grade the severity of injury. Standard neurological examination and neuroimaging studies should not be relied on to diagnose MTBI (have limited sensitivity). Common clinical signs of MTBI include an alteration of mental status or behavior and can be accompanied by other symptoms outlined below.
