Understanding Traumatic Brain Injury Grades and Their Impact on Your Oregon Personal Injury Claim

An ER doctor mentions a “mild” traumatic brain injury after a crash, and it’s tempting to walk out relieved. But a “mild” diagnosis can be misleading. In the world of brain injuries, that word carries a very specific medical meaning, and it doesn’t always reflect how much the injury will actually disrupt a life or how a claim should be valued.
How Doctors Grade a Brain Injury
Medical professionals classify traumatic brain injuries using the Glasgow Coma Scale, a tool that measures a patient’s eye opening, verbal responses, and motor responses on a scale from 3 to 15. A score of 13 to 15 is classified as mild, 9 to 12 as moderate, and 8 or below as severe. According to the Centers for Disease Control and Prevention, mild traumatic brain injuries make up the vast majority of all reported cases, but that classification is based on initial presentation, not necessarily the long-term outcome.
Why the Word “Mild” Can Be Misleading
Here’s the disconnect that catches a lot of injury victims off guard. A mild classification simply means a person wasn’t in a coma and had relatively normal eye, verbal, and motor responses shortly after the injury. It doesn’t mean the injury carries no lasting consequences. Mild traumatic brain injuries, sometimes called concussions, can still produce persistent headaches, memory problems, difficulty concentrating, sleep disturbances, and mood changes that last for months. Some individuals develop what’s known as post-concussive syndrome, where symptoms linger well beyond the typical recovery window.
Why the Grade Still Matters for a Claim
Even though a mild grade doesn’t guarantee a mild recovery, the initial classification still plays a real role in how insurance companies and courts approach a claim:
- It shapes the initial medical narrative that insurers rely on when evaluating the seriousness of the injury
- It influences what kind of follow up care and imaging gets ordered, which affects how well documented the injury becomes over time
- Moderate and severe injuries typically involve more extensive, more expensive treatment, which more directly supports higher damages
- A mild classification that later develops into long term symptoms requires additional documentation to show the insurer that the injury was more serious than the initial grade suggested
Building a Claim Around the Real Impact
Because the Glasgow Coma Scale reflects a snapshot taken shortly after the injury, a strong claim usually needs more than that initial number. Ongoing medical records, neuropsychological testing, and documentation from treating physicians describing how symptoms have actually affected daily life and the ability to work carry far more weight over time than the original grade alone. This matters especially for mild traumatic brain injuries, since insurers sometimes lean on that word “mild” to argue a claim should be valued lower than the injury’s real, lasting impact actually warrants.
