If you suffer a blow to the head, you may end up with a traumatic brain injury. Depending on how hard you hit your head (from an car accident or a slip and fall accident), you may have any number of symptoms ranging from a headache to complete unconsciousness.In order to diagnose a persons head injury accurately, a number of tests or exams need to be performed by a doctor to make sure the right course of action is taken. When it comes to brain injuries, its important to never try to diagnose yourself.Doctors and hospitals have the best equipment and knowledge to make sure a blow to the head doesnt lead to a worse traumatic brain injury. Scans like magnetic resonance images (MRIs) or tomography scans (CT or SPECT) help diagnose brain injuries along with other tests, namely like the Glascow Coma Scale.
What is the Glascow Coma Scale?
In 1974, Graham Teasdale and Bryan J. Jennett, neurosurgery professors at the University of Glascow (Scotland) came up with this scale with the purpose of providing an objective and reliable way of gauging the conscious state of a person with a head injury. The patients results are correlated against a grading scale, and the results give doctors a good indication about the severity of a traumatic brain injury.The scale has three different tests: eye, verbal and motor. Each function has a separate numbered scale that ranges from one to six (one being the most severe and six being the mildest). Those three numbers are then combined for a final grade.There are four grades of eye response:- Eyes dont open
- Eyes respond as a result of pain
- Speech causes eyes to open
- Eyes operate on their own
- No verbal response at all
- Sounds moans, but not necessarily words
- Inappropriate words
- Patient responds to questions, but with some confusion
- Patient responds to questions coherently and appropriately
- No motor response
- Extension to pain
- Abnormal flexion to pain
- Withdrawal to pain
- Localizes to pain
- Obeys commands
