Proving a Mild Traumatic Brain Injury When the Scans Read Normal

The defense will call it soft, subjective, and disproven by a clean head CT. Here is how to build a mild traumatic brain injury case that survives that framing and drives real value.

The adjuster's letter arrives with the same three sentences it always does. The head CT was normal. There was no loss of consciousness. The property damage was minor. Therefore, the argument goes, your client's cognitive complaints are exaggerated, litigation-driven, or someone else's problem. If you handle enough of these files, you learn that a mild traumatic brain injury case is won or lost long before trial, in the way you build the record and the order in which you prove things.

The word "mild" does most of the damage. It describes the acute presentation, not the outcome. A client who never lost consciousness and walked away from the crash can still spend two years unable to hold a conversation in a noisy room and quietly stepping down from a job she used to run. Your first job is to stop the jury from hearing "mild" and thinking "minor."

Start With the Contemporaneous Record

The most persuasive evidence in a concussion case is almost always the least dramatic: the emergency room triage note, the urgent-care intake, the primary-care visit three days later where the client mentioned she could not concentrate at work. These records were created before anyone was thinking about a lawsuit, which is exactly why they carry weight.

Pull every one of them and read them for symptoms, not diagnoses. A clinician who wrote "denies LOC" may have documented photophobia, nausea, or confusion in the same note. Those are the markers you want in front of the jury. Build a symptom timeline from the crash forward, drawing on the records, the client's own contemporaneous notes, texts, and calendar gaps. The defense loves a two-month silence between the ER and the first neurology visit. Close those gaps early, and if there is a genuine delay in treatment, develop why.

The initial ER note cuts both ways

If the ER did a Glasgow Coma Scale, note it. A GCS of 15 does not rule out a mild traumatic brain injury; the criteria for the diagnosis contemplate a normal or near-normal score. Have your expert explain that the standard definition turns on altered mental status, brief confusion, or post-traumatic amnesia, none of which requires a coma or a positive scan.

Why the Normal CT and MRI Do Not Help the Defense

Conventional imaging is designed to find bleeds, fractures, and mass lesions, the things that kill people in the first hours. It is not designed to detect the diffuse axonal shearing that characterizes concussion. Your radiology or neurology expert should be able to say plainly that a normal CT is expected in most mild traumatic brain injury cases and proves only that the client did not need a craniotomy. Framed correctly, the clean scan becomes a point for the plaintiff: the injury operates below the resolution of the imaging the defense keeps waving.

Neuropsychological Testing and the Malingering Question

A well-run neuropsychological evaluation is the backbone of the case. It measures processing speed, memory, executive function, and attention against normed populations, and it converts vague complaints into scores a jury can grasp. Choose an examiner who tests, not one who advocates.

The defense will accuse your client of faking, so meet that head-on. A credible battery includes embedded and stand-alone performance validity tests and symptom validity measures. When your expert can show the jury that the client passed validity testing, the malingering theme collapses under its own weight. If you skip validity testing, you have handed the defense neuropsychologist a gift. Insist on it, and make sure the raw data is preserved and produced.

Advanced Imaging: Promising, But Handle With Care

Diffusion tensor imaging and quantitative EEG can show white-matter and electrophysiological abnormalities that conventional imaging misses. In the right case they are compelling. They are also a frequent target of admissibility challenges, and courts remain split on whether these techniques meet the reliability threshold for individual diagnosis as opposed to group research.

Treat them as supporting evidence, never as the load-bearing wall. If the DTI is excluded, your case should still stand on the clinical picture, the neuropsychological data, and the lay testimony. Vet your imaging expert's methodology hard before you designate, because a shaky imaging opinion can drag down the credible parts of your presentation. Many state courts scrutinize novel imaging closely, so know your jurisdiction's standard.

Build the Before-and-After Through Baseline Witnesses

  • School and college transcripts, standardized scores, and work performance reviews establish who the client was before the crash.
  • A supervisor who can describe the client's decline, missed deadlines, or demotion turns cognitive scores into lived consequence.
  • A spouse, adult child, or close friend who saw the personality change, the irritability, and the lost words gives the jury the human version of the data.

These "before and after" witnesses are often more persuasive than any expert, because they have no financial stake and no jargon. Prepare them to testify to specific, concrete changes rather than conclusions. "He used to do the family taxes; now he cannot follow a recipe" lands harder than "he seems different."

Defeating the Property-Damage Argument

The low-property-damage defense is one of the most durable myths in this practice area, and biomechanics research does not support a clean dose-response relationship between bumper damage and brain injury. The brain moves inside the skull regardless of how the sheet metal held up. Retain a biomechanical expert where the venue and budget justify it, and use your treating physicians to explain that a functional injury is not measured in repair estimates.

Vocational and Life-Care Proof Drives Value

Liability and diagnosis get you in the door; damages proof determines the number. A vocational expert can quantify lost earning capacity when the client can no longer sustain the cognitive load of her prior job. A life-care planner captures the ongoing cost of cognitive therapy, accommodations, and support. This is where a mild traumatic brain injury stops being "soft" and becomes a measurable economic loss, and where the settlement value separates from the defense's nuisance offer.

These principles run through the rest of the practice too. The same disciplined baseline-building that anchors a concussion claim shows up across serious auto accident litigation, in the causation fights common to medical malpractice, and in the life-care and economic proof that carries a wrongful death case. Build the record early, test for validity, and let the ordinary contemporaneous documents do the heavy lifting.
