What Evidence Proves a Brain Injury Claim
A brain injury is the hardest common injury to prove, because it is often invisible on standard imaging and the person may not remember what happened. The case is built from a specific set of evidence, and the most important pieces are the ones families overlook.

Why the usual proof falls short
In most injury claims an X-ray shows the fracture and the injured person describes the accident. In a brain injury claim the CT scan is often normal and the claimant may have no memory of the event. The standard proof is absent on both sides.
So the case is built differently, from objective cognitive testing, advanced imaging where warranted, the accounts of those around the person, and the physical evidence of how the injury happened.
Neuropsychological testing
The single most important piece of evidence in most brain injury claims. It measures memory, attention, processing speed, language and executive function against normed data, converting symptoms the claimant reports into a measured, objective deficit.
Repeated over time, it establishes a trajectory. Where it shows impairment, it answers the insurer's routine argument that the symptoms are subjective or exaggerated.
Advanced imaging, where it applies
Standard CT and MRI often appear normal in brain injury. More advanced techniques, diffusion tensor imaging and others, can sometimes reveal the diffuse axonal damage that standard imaging misses.
This is specialized and not appropriate in every case, but where it shows structural damage it is powerful, because it converts an invisible injury into a visible one.
The accounts of family and colleagues
This is the evidence families most often fail to preserve and it is among the most persuasive. The people around the injured person notice the changes first, the personality shift, the lost competence at work, the exhaustion, the forgotten conversations, and those changes are frequently in no medical record.
Contemporaneous accounts, and testimony describing specific before-and-after change, describe the injury's actual effect on a life, which is what the claim is about. They cannot be reconstructed convincingly later.
The medical record and its gaps
The emergency and treating records establish the initial injury, but they routinely understate the cognitive effects because those are assessed later, if at all. Consistent follow-up, and every symptom reported as it arises, build the record that connects the injury to its consequences.
Gaps are read as recovery. A person who felt unable to explain their symptoms, or was told to rest and did not return, leaves a record that appears to show resolution.
Proof of how the injury happened
Causation is contested in brain injury cases more than in most, so the evidence of the event matters. Vehicle event data, camera footage, scene evidence, all establishing the forces involved and answering the fault argument the claimant may be unable to answer themselves.
In medical cases, the complete records reviewed by a qualified expert are the evidence, and the Chapter 74 report is the vehicle for it.
Summary
| Evidence | Proves | Note |
|---|---|---|
| Neuropsychological testing | Objective cognitive deficit | The single most important piece |
| Advanced imaging | Structural damage standard scans miss | Specialized, case-dependent |
| Family and colleague accounts | The real effect on function | Most often overlooked |
| Consistent medical follow-up | Injury connected to consequences | Gaps read as recovery |
| Event data and footage | How the injury happened | The claimant may not remember |
| Complete records, expert review | Medical causation | Chapter 74 in malpractice cases |

Frequently asked questions
Neuropsychological testing, because it converts self-reported symptoms into a measured, objective cognitive deficit against normed data. It answers the insurer's routine argument that brain injury symptoms are subjective.
Standard scans often appear normal in brain injury, so the case is built from objective cognitive testing, sometimes advanced imaging that reveals diffuse damage, the accounts of family and colleagues, and consistent medical follow-up.
Because they notice the cognitive and emotional changes first, and those changes are frequently in no medical record. Contemporaneous before-and-after accounts describe the injury's real effect on a life, which cannot be reconstructed convincingly later.
Yes. Gaps are read as recovery. A person told to rest who did not return, or who could not explain their symptoms, leaves a record that appears to show resolution, so consistent follow-up matters.
