    ### Instruction:
    What is the outlook for Traumatic Brain Injury ?
    ### Response:
    Approximately half of severely head-injured patients will need surgery to remove or repair hematomas (ruptured blood vessels) or contusions (bruised brain tissue). Disabilities resulting from a TBI depend upon the severity of the injury, the location of the injury, and the age and general health of the individual.
