[4] [5] The injury can cause a decline in mental function in the long term and in the emergency setting may result in brain herniation, a life-threatening condition in which parts of the brain are squeezed past parts of the skull. [3] Thus treatment aims to prevent dangerous rises in intracranial pressure, the pressure within the skull.

More than 50% of patients who suffer from a traumatic brain injury will develop psychiatric disturbances. [6] Although precise rates of anxiety after brain injury are unknown, a 30-year follow-up study of 60 patients found 8.3% of patients developed a panic disorder, 1.7% developed an anxiety disorder, and 8.3% developed a specific phobia.
