In contrast, secondary brain injury describes the damage caused following trauma due to complicating processes. injury (TBI) In moderate or severe brain injury, autoregulation is impaired so CBF varies with mean BP.

Traumatic brain injury (TBI) is called the silent epidemic as many of the symptoms are not readily detectable despite TBI being a worldwide public health issue. Traumatic brain injury (TBI), also referred to as head injury, is acute physical damage to the brain caused by an external impact.TBI is most frequently seen in young children, teenagers, and individuals above the age of 65.Motor vehicle accidents are the most common cause. In traumatic brain injury(TBI), primary brain injury occurs during the initial insult, and results from displacement of the physical structures of the brain.

The modern management of severe TBI has fallen into the domain of a multidisciplinary team led by neurointensivists, neuroanaesthetists, and neurosurgeons and is based on the avoidance of secondary injury, maintenance of cerebral perfusion pressure (CPP), and optimization of cerebral oxygenation.
