Glasgow Coma Scale – The GCS of a patient determines how “with it” they are.  Obviously a Doctor wouldn’t be saying “this patient has a reduced GCS as they’re not with it” but would justify their statement with a score.  It is scored out of 15 taking into account reaction of eyes, verbal and motor skills.  If the patient scores 1 in each they are GCS 3 – this is very bad and would suggest a coma of some sort . . . or at least very drunk! If they are GCS 15 then this is good.
