Traumatic brain injury claims

Most of these claims are not really arguments about how much an injury is worth. They are arguments about whether the injury exists at all, because the scan came back clean and nobody was knocked out. The Centers for Disease Control and Prevention has published material that addresses both of those points directly, and it is worth knowing what it says before anybody tells you your case is weak.

Key takeaways

  • The fight is usually about existence, not value. Which is unusual, and it changes what matters early.
  • Two standard defenses are answerable from public health sources. Not from advocacy, from the CDC.
  • The best evidence is often not medical imaging. It is testing, records over time, and people who can describe the change.
  • Delay hurts more here than almost anywhere. A gap between the crash and the first complaint is the argument you will face.
Editorial content, not legal or medical advice

This guide is written and reviewed by our editorial team to be accurate and current. It is general information about how these claims work. It is not legal advice, and it is emphatically not medical advice: nothing here diagnoses anyone, predicts any recovery, or should be used in place of seeing a clinician. Every clinical statement below is attributed to the Centers for Disease Control and Prevention and linked. We are a referral service and are paid by attorneys.

01 What these claims are actually about

Quick answer

In most injury claims both sides agree an injury happened and argue about its consequences. In brain injury cases the argument frequently starts a step earlier, with the proposition that nothing happened at all, because the objective tests everybody understands came back normal.

That is a strange position to be in. You know something is different. The imaging says otherwise, and the imaging is what an adjuster understands.

It is worth being clear that this is a claims problem rather than a medical one. Clinicians have well established ways of assessing these injuries that do not depend on a scan. The difficulty is that a claim is assessed by people who are not clinicians, using documents, and a normal scan is the most legible document in the file. Every TBI claim that runs into trouble runs into it here.

Bottom line: the early work is about building a record that speaks to people who cannot see the injury.

02 The clean scan argument

Quick answer

A normal CT or MRI does not establish that no brain injury occurred. The CDC's own provider material describes the disturbance in these injuries as functional rather than structural, and says it is typically associated with normal imaging.

This is the single most useful thing on this page, and it comes from a public health agency rather than from anybody with a case to win.

What the agency's clinical tool says
Function, not structure
CDC, Acute Concussion Evaluation, provider tool

The tool describes a concussion as an injury to the brain as a result of a force or jolt applied directly or indirectly to the head, which produces a range of possible symptoms, and may or may not involve a loss of consciousness. It then explains the mechanism: disturbance of brain function is related to neurometabolic dysfunction, rather than structural injury, and is typically associated with normal structural neuroimaging findings (i.e., CT scan, MRI). Read that last clause carefully. Normal imaging is not the exception in these injuries. It is what the agency describes as typical. Read the CDC tool

The agency's public guidance puts the same point in plainer words, stating that even if the injury doesn't show up on these tests, you may still have a mild TBI or concussion. An adjuster treating a clean scan as the end of the discussion is taking a position the CDC does not support.

03 When there was no scan at all

Quick answer

Sometimes the argument is not that the scan was clean but that nobody ordered one, which is offered as proof that no clinician was concerned. Current guidance actually advises against routine imaging, so the absence of a scan tells you about the guideline rather than about the injury.

This is a subtler version of the same mistake and it catches people out more often, because the file simply has nothing in it.

Why a scan may not have been done
Guidance advises against routine imaging
CDC, pediatric mild traumatic brain injury clinical guidance

The agency's guidance for providers directs them to not image routinely (including CT & MRI) and to use validated clinical decision rules predicting risk for more severe injury to determine need. Imaging in this setting is aimed at identifying bleeding and other structural emergencies, not at detecting the injury the claim is about. The CDC's public material makes the same point, noting that a scan is not needed to spot a mild TBI or concussion but may be used where there is a risk of bleeding on the brain. Read the CDC guidance

So the absence of imaging in a file is not evidence that nothing happened. It may be evidence that the clinician followed the guidance.

04 The loss of consciousness argument

Quick answer

You will be asked whether you were knocked out, and a no is treated as decisive. It is not. The CDC describes a concussion as something that may or may not involve a loss of consciousness, which means the question identifies a feature rather than a requirement.

The words are worth holding onto because the phrasing is unambiguous: may or may not. Most people answer this question honestly and watch the answer be used against them, without knowing that the agency's own definition does not require what they are being asked about.

A related trap is the word confused. People describe themselves as having been shaken or dazed and then correct it to fine, because they were embarrassed or because somebody more badly hurt was nearby. Those corrections end up in the record. If you were dazed, disoriented or could not remember the moments around the impact, that is worth saying plainly to a clinician rather than minimizing.

05 Why mild is a misleading word

Quick answer

Mild in this context is a clinical classification about immediate danger to life, not a description of how much the injury affects someone. The CDC says so directly and adds that the effects can be serious.

The label does real damage in claims, because a document saying mild reads to a non-clinician as a document saying minor.

What the label actually means
Usually not life-threatening, which is a different question
CDC, About Mild TBI and Concussion

The agency explains the terminology plainly: healthcare providers may describe these injuries as mild because they are usually not life-threatening. Even so, the effects of a mild TBI or concussion can be serious. The word is doing work about acute risk. It says nothing about whether somebody can return to their job, hold a conversation in a noisy room, or recognize themselves a year later. Read the CDC page

06 What the evidence actually is

Quick answer

Because imaging is frequently unhelpful, these claims are built from formal cognitive testing, a contemporaneous record of symptoms over time, and the accounts of people who knew the injured person before. That combination is what replaces a picture.

Each element is more persuasive the earlier it starts, which is why the first weeks matter disproportionately. A brain injury claim assembled six months late is not impossible, but it is a great deal harder than one begun in week one.

  • Neuropsychological testing. Formal assessment by a qualified specialist, producing measured results rather than description. Usually the backbone of the case.
  • A contemporaneous symptom record. Kept from the start, not reconstructed later. Dates, what happened, what could not be done that day.
  • People who knew you before. Family, colleagues and friends describing specific changes rather than general sympathy. Often the most affecting evidence there is.
  • Work and school records. Performance, absences and adjustments, which document the change without anybody having to be believed.
  • The earliest clinical notes. What was said in the first hours, including anything about being dazed or unable to recall.

Our guide to choosing a brain injury lawyer covers what to look for in a firm that handles this kind of proof regularly.

07 The pre-existing condition argument

Quick answer

Expect anything in your history to be offered as the real explanation: an earlier concussion, migraines, depression, ADHD, a stressful year. The existence of a prior condition does not mean a new injury did not happen, and in many states an injury that worsens an existing condition is still compensable.

This argument is uncomfortable because it is personal and because it uses true facts. It is also very commonly overstated, and it derails more than one TBI claim a year that should have succeeded.

  • Before and after is the answer. A documented level of functioning beforehand is the most effective response there is.
  • Worsening is generally recoverable. Many states treat aggravation of an existing condition as compensable, though the rules and the arithmetic vary.
  • Your whole history will be requested. Expect broad records demands and take advice before signing an open authorization.
  • Honesty is strategically correct. A history disclosed early is context. The same history discovered later is presented as concealment.

Valuation

08 How these claims are valued

Quick answer

By what the injury costs and takes away over a lifetime rather than by the size of the medical bills, which in these cases can be modest while the consequences are not. We are not going to give you a figure, and any page that does should be treated carefully.

The reason a traumatic brain injury settlement resists a headline number is that the largest components are the least standardised.

  • Lost earning capacity. Frequently the largest element, and it turns on the work somebody can no longer do rather than on the job they held.
  • Future care and support. Assessed by professionals rather than estimated, and projected across a lifetime.
  • The non-economic loss. Personality, relationships, independence. Real, substantial, and the hardest to evidence.
  • What coverage exists. A valuation is academic beyond the insurance available. Our guides to what a catastrophic case is worth and to what these claims settle for deal with valuation directly.

A traumatic brain injury settlement offered before the medical picture has stabilised is almost always premature, because the thing being valued is not yet known.

09 What to do in the first days

Quick answer

See a clinician and describe every symptom without minimizing, start writing things down the same week, and ask somebody close to you to note what they observe. The contemporaneous record is the case.

Five steps. The second and third cost nothing and are worth more later than almost anything else.

1

Get assessed, and do not minimize

Describe everything, including feeling dazed, foggy or unable to recall the impact. People routinely downplay symptoms and those notes become the record.

2

Start a daily note the same week

Date, symptoms, what you could not do. A phone note is fine. Its value comes from having started early rather than from being detailed.

3

Ask someone close to you to keep their own

Brain injury is frequently more visible from outside than in. A partner, parent or colleague recording specific changes is powerful evidence.

4

Keep every appointment and follow the advice

Gaps in treatment are the most commonly used argument against these claims, and missed follow-up is read as recovery.

5

Take advice before any recorded statement

You will be asked about being knocked out, about your history, and about how you feel today. All three answers are easy to get wrong while unwell.

Mostly about doubt.

10 Red flags

Quick answer

A clean scan presented as the end of the matter, an early offer arriving while symptoms are still changing, pressure to sign a blanket medical authorization, and a firm that has not mentioned neuropsychological testing.

The last one is the clearest signal about whether a firm has done this before.

How these claims get talked down

The scan closes the file. It should not, and the CDC material above is why. The early offer. These injuries evolve, and a figure agreed at eight weeks values something nobody has measured. The blanket authorization. Signing away access to your entire history invites an argument built from unrelated fragments of your life. No mention of formal testing. If nobody has raised neuropsychological assessment, the case is being run as an ordinary soft tissue claim.

One closing thought about any brain injury claim. What makes these different is not severity, since many are severe and some are not. It is that the injured person is routinely asked to prove something they cannot point at, to people who want to see a picture. The material quoted on this page exists precisely because that expectation is wrong, and it is published by an agency with no stake in your case. A free case review costs nothing, and you can read how we match people with attorneys before deciding anything.

How we vet every lawyer

This is a standard rather than an ordering. An attorney either clears it or does not.

  • Active, discipline-free license

    Verified good standing with the state bar, with no unresolved discipline on record. You can check this yourself too.

  • Brain injury proof experience

    A record of building these cases from testing and lay evidence rather than waiting for an image that may never come.

  • Capacity to fund expert work

    Neuropsychological and life care evidence is expensive and arrives early. The firm has to be able to carry it.

  • Clear contingency terms

    Fees and case costs put in writing up front, so you know exactly how it works before signing.

Tell us what happened and we will only match you when a case genuinely fits.

The clinical material quoted here is federal and applies everywhere. What varies by state is the law built on top of it: how an injury that worsens an existing condition is treated, how responsibility is divided where more than one person contributed, what may be recovered, and the deadline for bringing a claim. Where the injured person is a child or lacks capacity, the deadline may run differently, which is a question worth asking early rather than assuming. The general deadline, known as the statute of limitations, is running now.

Sources and authorities

Everything clinical on this page is quoted from the Centers for Disease Control and Prevention and linked.

Mild traumatic brain injury and imaging

  • CDC, Acute Concussion Evaluation, provider tool. Source of the description of concussion, of the statement that it may or may not involve a loss of consciousness, and of the explanation that the disturbance is related to neurometabolic dysfunction rather than structural injury and is typically associated with normal structural neuroimaging findings. CDC.
  • CDC, About Mild TBI and Concussion. Source of the statement that even if the injury does not show up on these tests you may still have a mild TBI or concussion, that a scan is not needed to spot one, and of the explanation that providers describe these injuries as mild because they are usually not life-threatening while the effects can be serious. CDC.
  • CDC, pediatric mild traumatic brain injury clinical guidance. Source of the direction to providers not to image routinely and to use validated clinical decision rules to determine need. CDC.

On the pediatric guidance. That document addresses children, and we have cited it for a narrow proposition: that clinical guidance discourages routine imaging and reserves it for identifying more severe injury. We have not extended anything else from it to adults, and a clinician is the right person to say what applies to any individual.

Why there is no settlement figure here. We have not published a range or an average, because we have no sourced basis for one and because the largest components of these claims are the least standardised. Any figure would be a guess wearing the clothes of information. What a claim is worth depends on the individual loss and, just as importantly, on what insurance exists to pay it.

What we have left out. We have given no prevalence, incidence or recovery statistic, because the CDC material we read this session did not provide one we could state precisely in this context. We have not set out the severity classification bands, which reached us through secondary sources rather than CDC material we read directly. And we have reproduced no material published by medical journals, professional societies or private research bodies, which is their copyrighted work rather than public information.

Common questions, answered

General information, not legal or medical advice. What a claim recovers and how long you have are set state by state, so check anything here against your own state and your own attorney.

My CT scan was normal. Do I still have a case?

Very possibly. What a CT is looking for is bleeding and other physical damage to the structure of the brain, and it is genuinely good news that it found none. But that is a different question from whether your brain is working the way it did before, and the CDC has published material saying in terms that these injuries can be present when the tests come back clean. So the scan answers one question and is then used to close a different one. Your case rests on evidence of the effects.

I was never knocked out. Does that rule out a brain injury?

No. The CDC describes concussion as an injury that may or may not involve a loss of consciousness, which makes blacking out a possible feature rather than a requirement. The question gets asked so consistently that people assume a no ends the discussion. It does not. Being dazed, disoriented or unable to recall the moments around impact matters, and is worth describing to a clinician rather than brushing aside.

Nobody gave me a scan at all. Is that a problem?

It is used as one, but current clinical guidance actually discourages routine imaging and reserves it for identifying more severe injury such as bleeding. So an absent scan may reflect a clinician following the guidance rather than a clinician being unconcerned. What matters far more is whether your symptoms were described and recorded at the time, which is something you can still influence now if it has not happened yet.

What does mild actually mean on my paperwork?

Less than it sounds, and something quite different from minor. The CDC explains that providers use the word because these injuries are usually not life-threatening, and adds directly that the effects can nonetheless be serious. It is a classification about immediate danger. It says nothing about whether you can work, concentrate, or feel like yourself, and it should not be read across as though it did.

What is neuropsychological testing and why does it keep coming up?

It is formal assessment by a qualified specialist that measures memory, attention, processing speed and related functions, producing results rather than descriptions. In claims where imaging is unhelpful it usually becomes the backbone of the proof, because it converts something experienced into something documented. If nobody involved in your case has raised it, that is worth asking about.

They want my entire medical history. Do I have to agree?

Take advice before signing anything open-ended. Broad authorisations let an insurer go looking through unrelated parts of your life for an alternative explanation, and in these cases that search is routine rather than exceptional. Relevant history does have to be dealt with, and dealing with it openly is usually the stronger position. The question is scope, and scope is negotiable.

I had a concussion years ago. Does that sink this claim?

It will certainly be raised, and it is a weaker point than it appears. The relevant comparison is how you were functioning immediately before this injury against how you are functioning now, and evidence of that gap is the answer. Many states also treat the worsening of an existing condition as compensable, though the rules and the arithmetic differ, so this is a question for an attorney in your state.

How much is a case like mine worth?

We deliberately publish no figure. The biggest components in these cases are lost earning capacity, future care and the non-economic loss, and none of those is standardised enough for an average to mean anything. Medical bills are often modest while the consequences are not, which makes bill-based estimates particularly misleading here. What is available to pay also depends on the insurance behind the claim.

They have offered to settle already. Should I take it?

Be very cautious with an early offer in this particular kind of claim. These injuries change over months, and some effects only become apparent when somebody returns to work or study and finds they cannot manage what they used to. A settlement signed before the picture has stabilised puts a price on something nobody has finished measuring, and it cannot be revisited afterwards.

My family says I have changed but I feel fine.

That combination is common enough to be worth taking seriously rather than dismissing. Changes in memory, temper, planning and attention are frequently more visible from outside than from inside, which is exactly why accounts from people who knew you before carry so much weight in these claims. If people close to you are saying it, ask them to write down specific examples with dates, and raise it with a clinician.

Do I have to pay anything up front?

Injury firms generally work on a contingency basis, meaning the fee is a percentage of what is recovered set out in the written agreement and there is nothing to pay up front. Case costs, meaning experts and records and filing fees, are a separate item from the fee, and the agreement should say plainly who carries them and what happens to them if the case does not succeed.

Is what I tell you private?

Yes. What you share in a case review is kept private and is used only to match you with an attorney who fits your situation. One distinction is worth understanding: true legal confidentiality, called attorney-client privilege, only attaches once you actually have an attorney-client relationship with a lawyer. Submitting a form to a referral service is not the same thing. If that matters to you, raise it directly with the attorney.

What does it cost to use MVA Lawyer Network?

Nothing. We are a free, independent referral service, not a law firm, and we do not give legal advice. Requesting a case review costs you nothing and puts you under no obligation. When a situation fits, we connect you with an independent attorney who reviews it directly, and we may be paid a referral fee by that attorney. That fee does not add anything on top of their percentage.

A clean scan is not a finding that nothing happened, and the CDC says so.

One short, private form. No cost, no obligation, and no fee unless there is a recovery.
