In medicine, brain injuries are "acute and chronic injuries to the brain, including the cerebral hemispheres, cerebellum, and brain stem. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with diffuse axonal injury or coma, post-traumatic. Localized injuries may be associated with neurobehavioral manifestations; hemiparesis, or other focal neurologic deficits.."[1]

Types of brain injury include:


Diagnosis

X-ray computed tomography of the head should be considered, especially if the patient fulfills any criteria from the New Orleans Criteria clinical prediction rule:[9]

"headache, vomiting, an age over 60 years, drug or alcohol intoxication, deficits in short-term memory, physical evidence of trauma above the clavicles, and seizure"

X-ray of the cervical spine should be considered, especially if the patient fulfills criteria from the Canadian C-Spine Rule clinical prediction rule for neck injury: [10]

  • Age 65 years or more
  • Paresthesias in extremities
  • Dangerous fall ("elevation >=3 ft or 5 stairs; an axial load to the head (e.g., diving); a motor vehicle collision at high speed (>100 km/hr) or with rollover or ejection; a collision involving a motorized recreational vehicle; or a bicycle collision")
  • Inability to rotate the neck 45° to the right and left
    • Only test if "simple rear-end motor vehicle collision, sitting position in ED, ambulatory at any time since injury, delayed onset of neck pain, or absence of midline C-spine tenderness"[11]
  • Glasgow Coma Scale less than 15 (the Canadian C-Spine Rule was only designed for alert patients)

Treatment

Mild injury may not benefit from multidisciplinary[12] or rehabilitation[13] treatment.
