Since June 1, 2016, the criteria for a catastrophic impairment can be found under section 3.1(1) of the SABS. For a traumatic brain injury to be considered a catastrophic impairment, it must be confirmed by medical imaging and a Glasgow Outcome Scale assessment.
Medical imaging and the assessment must provide objective proof that the TBI has resulted in:
A vegetative state one month or more since the car accident
Upper or lower severe disability for six months or more since the car accident
Lower moderate disability one year or more since the car accident
