Glasgow Outcome Scale

The Glasgow Outcome Score attempts to objectively assess outcomes of brain injury by degree of recovery. It makes use of five categories. The first version was developed in 1975 by Jennett and Bond. An alternative quantification of outcomes in common use is the Modified Rankin Scale.

1. Death Severe injury or death without recovery of consciousness
2. Persistent vegetative state Severe damage with prolonged state of unresponsiveness and a lack of higher mental functions
3. Severe disability Severe injury with permanent need for help with daily living
4. Moderate disability No need for assistance in everyday life, employment is possible but may require special equipment.
5. Low disability Light damage with minor neurological and psychological deficits.
