Glasgow Coma Scale (GCS)
The instrument is freely available here: Glasgow Coma Scale Link
Supplemental – Highly Recommended:  Stroke (based on study type, disease stage and disease type)
Short Description of Instrument
The Glasgow Coma Scale (GCS) was developed to overcome the misunderstandings and confusion about comatose patients. The GCS is also used to assess neurological trauma as well as to document and predict neurological changes. It is considered the gold standard in this regard and is widely used.
Three questions must be answered in regards to unconsciousness and coma with the first addressing eye opening, the second motor function and the third verbal response. Scores range from 3-15 total points with lower scores indicating patients in comatose.
