A practical, step-by-step breakdown of the medical, physical, and financial evidence that strengthens a brain injury claim — and how to avoid the mistakes that weaken one.
Find Legal Help Near YouA traumatic brain injury rarely announces itself the way a broken bone does. Symptoms can take hours, days, or even weeks to surface, and by the time they do, the evidence that would have proven what happened may already be fading. For someone recovering from a car crash, a fall, or a workplace accident in McKinney, that timing problem is exactly why evidence collection matters so much — and why it needs to start early.
This guide walks through the specific categories of evidence that carry weight in a Texas brain injury claim, the state laws that shape how long you have to act, what these cases are typically worth, and the missteps that quietly derail otherwise strong claims. Whether you're a few days removed from the accident or already deep into medical treatment, a McKinney Brain Injury Lawyer can help you put this roadmap into action.
The strongest brain injury claims rely on complete medical records and imaging (CT, MRI, neuropsychological testing), a certified accident or police report, witness statements, photo or video documentation, expert medical testimony connecting the injury to the accident, and proof of financial losses such as lost wages and future care costs. The more thoroughly each category is documented and preserved early, the more leverage you have in negotiations or at trial.
Evidence doesn't collect itself, and insurance adjusters are trained to poke holes in claims that are missing key documentation. Here's the order most attorneys follow when building a brain injury evidence file from the ground up.
The single most important piece of evidence is a documented paper trail showing you sought treatment right away and continued follow-up care. Gaps in treatment give insurers an opening to argue your injury wasn't serious — or wasn't caused by the accident at all. If you're unsure whether your symptoms qualify, it helps to review the common symptoms of TBI after an accident so nothing gets dismissed as "just a headache."
CT scans, MRIs, and neuropsychological evaluations create an objective record of the injury that's difficult for an insurance company to dispute. Cognitive testing — measuring memory, processing speed, and executive function — is particularly persuasive because it quantifies impairments that aren't visible on a scan.
An official accident report establishes the basic facts: date, location, parties involved, and often an initial assessment of fault. Request a certified copy as soon as possible, since these reports form the factual backbone that everything else gets built around.
Memories fade fast. Anyone who saw the accident, or who interacted with you immediately afterward and noticed confusion, slurred speech, or disorientation, can provide testimony that's far more credible when gathered within days rather than months.
Photos and video of the accident scene, vehicle damage, visible injuries, and your recovery process over time all help paint a complete picture. Understanding the common causes of traumatic brain injuries after accidents can also help you identify contributing factors — like a defective safety feature or hazardous road condition — worth photographing.
A treating physician or an independent medical expert can connect the dots between the accident and your diagnosis in a way a jury or adjuster will understand. Expert testimony is often what separates a modest settlement offer from one that actually reflects the injury's true impact.
Keep every medical bill, pay stub showing missed work, and receipt for related expenses like transportation to appointments or in-home care. If your injury affects your long-term earning capacity, a life-care planner or economist may need to project future costs.
Texas law shapes almost every part of how a brain injury claim is built and valued. A few rules matter more than most:
Recognizing symptoms early also matters for both your health and your claim. If the injury followed a car crash, this overview of signs of a brain injury after a car accident is worth reading alongside your medical evaluation.
Traumatic brain injuries are far more common — and far more consequential — than most people realize.
According to the Centers for Disease Control and Prevention (CDC), traumatic brain injuries contribute to hundreds of thousands of hospitalizations and emergency visits across the country every year — underscoring why documentation from the very first ER visit carries so much weight later on. For a deeper look at how these injuries evolve, see our guide on the long-term effects of TBI after a car accident.
There's no flat number for what a brain injury claim is "worth" — value depends heavily on severity, the strength of your evidence, and the extent of your financial losses. That said, general ranges help set expectations:
| Injury Severity | Typical Range | Key Value Drivers |
|---|---|---|
| Mild concussion, full recovery | $15,000 – $75,000 | Medical costs, short-term lost wages |
| Moderate TBI, extended recovery | $100,000 – $500,000 | Therapy, rehabilitation, longer work absence |
| Severe or permanent TBI | $500,000 – $2M+ | Lifetime care, lost earning capacity, pain and suffering |
Compensation generally accounts for medical expenses (past and future), lost income, reduced earning capacity, pain and suffering, and — in severe cases — the cost of long-term or in-home care. For a full breakdown of how insurers and courts arrive at these figures, review how brain injury compensation is calculated and this look at average settlements for traumatic brain injury cases.
Medical records paired with diagnostic imaging are typically the most persuasive evidence, since they create an objective, timestamped record of the injury. Expert testimony connecting those records to the accident is a close second.
In most cases, two years from the date of the accident. Certain circumstances involving minors or delayed discovery of the injury can adjust this timeline, so it's worth confirming your specific deadline as soon as possible.
Yes, as long as you're found 50% or less at fault. Texas reduces your compensation in proportion to your share of responsibility, but doesn't bar recovery entirely below that threshold.
It's still worth a consultation. Mild traumatic brain injuries can develop lingering cognitive or emotional symptoms that aren't obvious right away, and speaking with an attorney early can help make sure your evidence is preserved in case your condition changes.
A denial isn't necessarily final. Additional medical documentation, expert opinions, or a formal appeal can often change the outcome, particularly when new evidence strengthens the causal link between the accident and your diagnosis.
Most personal injury attorneys, including those handling brain injury cases, work on contingency — meaning there's no upfront cost, and fees are only collected as a percentage of any settlement or verdict.
Every day that passes can mean lost evidence or a missed deadline. Connect with an experienced brain injury attorney to review your case and protect your right to compensation.
