Diagnosis
In order to access head injuries, professionals utilize the Glasgow Coma Scale (GCS). The scale goes from 3 to 15 depending upon the seriousness of the injury. This is based on the symptoms that you show and the damage that has been done to the brain. 3 is the most severe, while 15 means less severe.
For those who score between 9 and 12, they have a moderate head injury. Severe is classified as 8 or lower. Those who score a high GCS score, may later downgrade the seriousness after they have been re-evaluated.
In many situations, further tests are required in order to access the damage. For example, utilizing computerized tomography scans, otherwise known as a CT scan.
