If your goal is a realistic estimate, focus on the evidence that usually drives the numbers in California settlements:
1) Early medical records and symptom timeline
For concussions and more serious TBIs, insurers look for the “paper trail” that connects the accident to documented neurological symptoms. In California, early documentation matters because it helps establish causation and shows the seriousness of the injury from the start.
What this typically includes: ER/urgent care records, CT/MRI reports (when done), discharge instructions, and follow-up visits.
2) Functional impact—especially on work and household tasks
Many people feel their injury most in day-to-day performance: forgetting conversations, trouble concentrating, headaches that flare with screen time, or difficulty managing stress. In a demand for compensation, that isn’t just “what you’re dealing with”—it’s how damages are explained.
Examples that matter: work restrictions, missed shifts, reduced productivity, need for supervision, or the inability to perform routine household responsibilities.
3) Objective support for subjective symptoms
Head injury symptoms can be hard to quantify, but they aren’t invisible to the legal system. Providers can document them through clinical notes, therapy records, neurocognitive testing, and consistent reporting.
4) Accident documentation that matches the injury mechanism
In Clearlake, claims often hinge on the basic mechanics: how a person fell, what was struck, speed or impact details in a crash, and whether witnesses observed confusion, disorientation, or loss of consciousness.
Even when scans are normal, the mechanism plus consistent medical notes can still support a serious injury claim.
