a. Definition: The term means the physical, cognitive and/or behavioral/emotional TBI TBI residual disability resulting from an event of external force causing an injury to the brain. b. TBI Events The is a traumatically induced structural injury and/or TBI event physiological disruption of brain function resulting from an external force indicated by of the following clinical signs immediately at least one following the event any period of loss of consciousness or decreased consciousness any loss of memory for events immediately before or after the injury any alteration in mental state at the time of the injury (confusion, disorientation, slowed thinking, etc.) neurological deficits, whether or not transient, or intracranial lesion. Notes: The TBI event has two necessary components: the and the external force of brain injury immediately following the identifiable acute manifestations external force. Not all individuals exposed to an external force will have brain injury, and therefore, they will not meet the criteria for having a TBI event. The acute manifestations may resolve without chronic disability, or a chronic disability may result. Although unconsciousness or reduced consciousness is common in TBI events, these are required. Any one of the five signs will be sufficient. not means any of the following events c.
