The seriousness of a traumatic brain injury is typically classified into three levels which include mild, moderate, and severe. The classification is based on various factors, such as the length of time the individual loses consciousness. In order to establish the seriousness of the injury, a medical professional will need to evaluate the injury.
Some of the factors that help determine the severity of a brain injury include:
How long you were unconscious.
Where the injury is located on your brain.
The length of time you experienced memory loss.
