The diagnostic tools of the CT scan and the MRI can be very beneficial in regards to diagnosis, but are only recommended if the chosen medical therapy is not giving any improvement. Unequal pupil size (anisocoria) is another indication of brain injury. To understand the differences between a coma, a persistent vegetative state, and brain death, c lick here. The mental status of your pet, along with reflex capabilities will be confirmed.

The researchers urge the clinical community to assess and evaluate GCS-P while cautioning that clinical assessment tools should not be the sole basis for predicting outcome and determining how to treat patients with brain trauma. For patients with a GCS-P score of 1, physicians predicted a mortality rate and unfavorable outcome rate of 74 percent and 90 percent, respectively. For example, in patients with a GCS score of 3, physicians predicted a mortality rate of 51 percent and an unfavorable outcome of 70 percent. The combined score also extended information for physicians. Simply adding pupil reactivity scores to the GCS score was as accurate as more complex methods of evaluating brain trauma. Of the IMPACT patients, 81 percent had severe head injuries compared to 39 in CRASH.Ĭombined GCS Score Improves Accuracy of Prognosis Third nerve palsy (TNP) can cause the pupils to be different sizes. To find out if adding scores from pupil response to the GCS scores would improve clinicians’ ability to predict mortality or an unfavorable outcome, the creators of the GCS and researchers at the University of Edinburgh in Scotland assessed the health records of more than 15,000 patients from the databases of two trials, CRASH (Corticosteroid Randomization After Significant Head Injury) and the IMPACT (International Mission for Prognosis and Clinical Trials in TBI). Share on Pinterest Third nerve palsy or Horners syndrome may cause anisocoria. A score of 2 means both pupils are non-reactive to light a score of 1 means one pupil is non-reactive and a score of 0 means neither pupil is non-reactive. Abnormalities such as an irregular pupil size or shape, or a delayed or nonreactive pupil can be indicative of significant head trauma.
In addition to the GCS score, doctors also look at pupil response.

A person’s total score on the GCS-a minimum of 3 indicates deep coma, a maximum of 15 indicates full consciousness-indicates his or her level of consciousness after brain trauma.
A Simple Eye Test Could Improve Care of Brain-Injured PatientsĪdding scores from a simple eye test to scores of the Glasgow Coma Scale (GCS) helps doctors predict mortality and outcomes in patients with brain trauma more accurately, according to a study published in the Journal of Neurosurgery on April 10.ĭoctors use several measures to predict a patient's prognosis in the first few hours of a traumatic brain injury (TBI), including the GCS, which measures whether patients can open their eyes, speak, or move.
