Glasgow coma scale not best predictor of long term outcome following traumatic brain injury

The findings on the glasgow coma scale (GCS) , the presence of post traumatic amnesia (PTA) and abnormal findings on an MRI are often looked at to predict the long term consequences of traumatic brain injury.  New research indicates that the presence and duration of post traumatic amnesia as well as structural changes found on MRI studeis are better predictors then the use of the glasgow coma scale to predict long term consequences of traumatic brain injury. The study can be found in the journal  Brain Inj. 2009 May;23(5):396-402.
