For the purpose of this review, TBI is defined as “a traumatically induced structural injury and/or physiological disruption of brain function as a result of an external force.” Examples of such injuries include head strike by an object, rapid acceleration/deceleration-related injuries with damage to brain tissue, and penetration by a foreign body which induces brain injury. TBI is characterized by new onset or worsening of at least one of the following clinical signs or symptoms immediately following the event:Any period of loss or a decreased level of consciousness (LOC)Any loss of memory for events immediately before or after the injury (i.e., post-traumatic amnesia)Any alteration in mental state at the time of injury (i.e., confusion, disorientation, slowed thinking)Neurologic deficits (i.e., weakness, loss of balance, change in vision, praxis, sensory loss, aphasia) that may or may not be transient
