The Glasgow Outcome Score (GOS) is a scale of patients with brain injuries, such as cerebral traumas that groups victims by the objective degree of recovery. The first description was in 1975 by Jennett and Bond.[citation needed]


The Glasgow Outcome Score applies to patients with brain damage allowing the objective assessment of their recovery in five categories. This allows a prediction of the long-term course of rehabilitation to return to work and everyday life.[citation needed]

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.
