Many online calculators assume a simplified set of facts—like a short treatment window or consistent symptom documentation. Real cases are different, particularly when the injury impacts:
- Return-to-work timelines after an accident on a commute route
- Sleep disruption and concentration problems that affect performance even when scans look “normal”
- Ongoing medical follow-up (neurology, concussion specialists, therapy)
- Functional limits that show up in missed shifts, reduced hours, or job changes
Because TBI symptoms can fluctuate, insurance adjusters focus on whether your medical records tell a coherent story from the day of the incident onward. That’s why a “range” from a calculator may not reflect the evidence your file actually contains.
