Glasgow Coma Scale (GCS)

The Glasgow Coma Scale is the standard 3-to-15 score for level of consciousness after head trauma, built from eye-opening, verbal, and motor responses — and one of the first numbers a legal reader should find in any brain-injury file.

Updated

Three components sum to the score: eye opening (1–4), verbal response (1–5), motor response (1–6). A fully alert patient is 15; deep unresponsiveness is 3. Conventional severity bands: 13–15 mild, 9–12 moderate, 8 and below severe (“GCS 8, intubate”). Charts often record the components — “E4V5M6” — not just the total, and EMS run sheets typically capture the first score at the scene.

In traumatic brain injury litigation, GCS is where the severity fight starts. A scene GCS of 14–15 anchors the defense framing of “mild TBI” — but the score measures consciousness at a moment, not outcome, and mild-by-GCS injuries can carry lasting cognitive symptoms; plaintiff teams pair early scores with later neuropsychological findings rather than fighting the number. Trajectory matters more than any single value: scene, ER arrival, and serial scores tell a story a lone number can’t.

Read carefully for confounds the chart itself may note — intoxication, sedation, intubation (which caps the verbal score, often charted as “V1T”) — each a reason a score under- or overstates the injury.

In the fact record

GCS values are scattered across EMS sheets, ER notes, and flow charts. Extracted onto one timeline with citations, the trajectory — and any suspicious jumps between documents — reads at a glance.
