Traumatic brain injury (TBI) is defined as a structural injury to the brain or a disruption in the normal functioning of the brain as a result of a blunt or Penetrating head injury. Head injury refers to trauma to the head that may or may not be associated with TBI, soft tissue injury, or skull fractures. Primary brain injury occurs as an immediate consequence of head injury at the time of the trauma.Secondary Brain Injury is indirect and results from physiological changes triggered by the initial impact and/or acute management measures; it is preventable to a certain degree. TBI is most frequently seen in young children, teenagers, and individuals older than 65 years, with falls and Motor vehicle collisons being the leading causes. The Glasgow Coma Scale is a commonly used scoring system used to assess the severity of TBI and guide management. Clinical Features of TBI depend on the severity, type, and location of brain injury. Impaired consciousness is common in severe TBI whereas patients with mild TBI may only present with transient confusion and headache.Neuroprotective measures to prevent or minimize secondary brain injury should be the main focus of initial management of all patients with TBI. Patients with moderate TBI or severe TBI should be transferred to a neurocritical care unit at the earliest. After initial resuscitation, a head CT without contrast should be obtained to identify the type and extent of injury. Definitive management varies depending on the type and severity of injury.
