When people search for a “settlement calculator,” they’re usually trying to estimate what insurers may offer. In reality, TBI values tend to move with three things:
- The documented brain injury severity (diagnosis, treatment course, objective findings when available)
- The functional impact (work restrictions, daily limitations, cognitive or emotional changes)
- The strength of causation (how clearly the accident mechanism connects to the symptoms)
For Glen Ellyn cases, insurers frequently scrutinize the timeline—especially when symptoms appear to fluctuate with stress, return-to-work attempts, or treatment gaps.
