The headache fades in a day or two, but the fog doesn't. Words come slower. A quiet room feels safer than a family dinner. Six weeks later, the person who got hurt is still waiting to feel like themselves again, and still hasn't heard anyone explain what any of this means for the accident that caused it.
If a concussion has turned your routine upside down, here's what determines whether New Jersey law gives you a way to hold someone accountable for it.
If a concussion has turned your routine upside down, a New Jersey personal injury lawyer can help you seek compensation when someone else caused the accident. Here's what the law requires and what can affect your ability to recover damages.
Key Takeaways: Can I Sue for a Concussion in New Jersey?
- A concussion is a type of traumatic brain injury and can form part of a personal injury claim when another party's legally actionable conduct caused the injury.
- The concussion diagnosis itself does not establish negligence or liability.
- The cause of the injury matters, since different New Jersey rules can apply to automobile accidents, workplace injuries, and premises accidents.
- Concussion symptoms can appear hours or days after the injury, so delayed symptoms do not necessarily rule one out.
- A normal imaging result may not show the concussion signs; diagnosis rests on more than a single scan.
- New Jersey generally applies a two-year statute of limitations to personal-injury actions, subject to exceptions.
- Comparative negligence can reduce damages when the injured person is also found partly responsible.
Can I Sue for a Concussion in New Jersey?
A concussion can be part of a New Jersey personal injury claim when another person's wrongful act, neglect, or default caused the injury and the required elements of the claim can be established. The diagnosis alone isn't enough; the claim needs to connect the concussion to another party's legally actionable conduct.
New Jersey builds ordinary negligence claims around four pieces:
- Duty: a legal obligation to act with reasonable care toward others.
- Breach: conduct that falls short of that obligation.
- Causation: a link between the breach and the accident that followed.
- Damages: the harm that resulted, including the concussion itself.
New Jersey's Model Civil Jury Charges set out this framework for the jury in ordinary negligence cases. The same basic question can come from distinctly different situations: another driver causing a collision, a property condition contributing to a fall, or negligent conduct behind some other kind of accident. Two situations change this general framework: a workplace injury generally runs through New Jersey's workers' compensation system, and an automobile case can involve New Jersey's separate limitation-on-lawsuit rules.
When Can You Sue for a Concussion in New Jersey?
The legal route for a concussion claim depends heavily on how the injury happened.
| How the concussion happened | Potential legal route | Special New Jersey rule |
| Car accident | Negligence claim against the other driver | Tort option under N.J.S.A. 39:6A-8 can limit non-economic damages |
| Slip-and-fall or premises accident | Premises-liability claim against the property owner or occupant | Requires identifying the dangerous condition and connecting it to the fall |
| Workplace accident | Workers' compensation, not an ordinary lawsuit against the employer | Exclusivity rule under N.J.S.A. 34:15-8, subject to the intentional-wrong exception |
A motor-vehicle concussion claim can involve both negligence principles and New Jersey's automobile insurance tort options. Under N.J.S.A. 39:6A-8, a person who selected the limitation-on-lawsuit option generally can't recover non-economic damages unless the injury falls within a statutory category, including a permanent injury within a reasonable degree of medical probability. Not every concussion satisfies that category, so the tort option needs to be checked before assuming a claim automatically covers pain and suffering.
A concussion caused by a fall can potentially support a premises-liability claim, but not every fall on someone else's property is automatically actionable; the evidence needs to identify the dangerous condition or negligent conduct and connect it to the accident.
An employee injured in a compensable workplace accident generally proceeds through the workers' compensation system, not an ordinary negligence lawsuit against the same employer, under the exclusivity framework in N.J.S.A. 34:15-8, subject to the statutory intentional-wrong exception.
What Evidence Helps Prove a Concussion After an Accident?
Proving a concussion claim means documenting both the injury and how it happened.
| Medical records Emergency care, diagnosis, follow-up visits, symptoms, treatment, and referrals. | Accident records Accident reports, photos, video, witness accounts, and information about how the accident happened. | Daily-life records Work restrictions, missed work, and changes in memory, concentration, sleep, balance, or mood. |
Expert medical testimony can also matter, particularly on diagnosis, causation, and ongoing effects, in cases where those questions are genuinely disputed.
What Compensation Can You Seek for a Concussion?
A concussion claim can involve both economic losses, calculated from bills and pay records, and non-economic losses that have no fixed calculation behind them. What's recoverable depends on which of these the evidence supports in a given case.
Economic losses
- Medical expenses related to diagnosis and treatment
- Lost wages or income caused by the injury
- Future economic losses when supported by the evidence
Non-economic losses
- Pain and suffering
- Effects on ordinary activities and quality of life, where supported by the evidence
Documenting both the immediate expenses and the effects that continue matters for either category. Ostrowski v. Cape Transit Corp. illustrates how central disputed medical evidence can become in a case like this.
The defendant admitted fault for the accident itself, but contested the severity of the plaintiff's head injury at trial, introducing expert testimony and video evidence to argue the plaintiff was overstating his symptoms. The case is older, and it's worth citing here for what it shows about how brain-injury damages get litigated, not as a benchmark for what a current claim might be worth.
How Do Delayed Symptoms Affect a Concussion Claim?
Concussion symptoms don't always show up right away, and that timing doesn't say what people often assume it does.
- The accident happens.
- Some symptoms appear right away.
- Other symptoms surface hours or days later, and can change as recovery continues.
- A medical evaluation documents what's present at that point.
- Follow-up visits track how the condition develops from there.
Relevant symptoms can include headaches, dizziness, balance problems, fatigue, concentration problems, memory problems, sleep changes, and emotional changes.
A later appearance of symptoms doesn't by itself establish or disprove that the accident caused them; what matters is whether the medical documentation connects the symptoms to the accident and tracks how they developed over time. Prompt medical evaluation and consistent follow-up records serve two purposes at once: supporting recovery and building the documentation a claim may later need.
What if Imaging Tests Do Not Show the Concussion?
A concussion can be missed during an initial examination, especially when symptoms are subtle or have not fully developed yet. A person may also have trouble recognizing or describing changes in memory, concentration, mood, sleep, or daily functioning.
A concussion diagnosis can involve several parts of an assessment:
- Injury history: How the accident happened and whether there was a blow or jolt to the head or body
- Reported symptoms: Headaches, dizziness, memory problems, or sensitivity to light
- Physical examination: Balance, coordination, vision, and other neurological functions
- Cognitive testing: Attention, memory, or processing speed when further assessment is appropriate
A normal CT scan does not rule out a concussion. CT imaging is mainly used when clinicians need to check for more serious structural injuries, such as bleeding. The diagnosis relies on the overall clinical picture rather than one test or scan.
If symptoms persist, change, or become more noticeable after the initial evaluation, follow-up can provide a clearer picture of the injury and its effects.
What Must You Prove to Recover Compensation in New Jersey?
Recovering compensation for a concussion comes down to five concrete requirements:
- A legally recognized duty existed.
- The defendant breached that duty through negligent or otherwise actionable conduct.
- That conduct caused the accident and the concussion.
- The concussion caused compensable harm or losses.
- The claim was brought within the applicable time limit.
Causation deserves particular attention. Showing that a person has a concussion isn't the same as showing what caused it; the evidence needs to connect the defendant's conduct to both the accident and the injury. Pre-existing conditions or other possible causes can become relevant when the extent or source of symptoms is disputed, and medical evidence tends to matter most when symptoms persist well past the initial injury.
On timing, New Jersey generally gives two years to bring a personal-injury action, though the statute itself contains the phrase “except as otherwise provided by law”. Not every defendant or circumstance follows exactly the same deadline, so confirming which rule applies matters before assuming the standard two years is the only relevant date.
How Can Comparative Negligence Affect an Injury Claim in New Jersey?
New Jersey follows a modified comparative negligence framework: a defendant may argue that the injured person also contributed to the accident, and contributory negligence doesn't bar recovery as long as the claimant's share of fault isn't greater than the fault of the person or people being sued. Damages get reduced by whatever percentage of negligence is attributed to the person recovering.
Assessed damages: $100,000
Injured person's share of fault: 20%
Reduction: $100,000 × 20% = $20,000
Recoverable amount: $100,000 − $20,000 = $80,000
The actual percentages in a real case depend entirely on the evidence, not a formula anyone can predict in advance.
This is why a part of the evidence about how the accident occurred matters even when the concussion itself is well documented; the medical record proves the injury, but the accident evidence shapes how much of the resulting damages the injured person recovers.
What Damages May Be Available in a Personal Injury Claim?
Proving a concussion happened is one task. Establishing what it's worth is another, and that second task determines a claim's value.
A concussion that clears up within a few weeks can point toward a different set of damages than one that leaves lasting cognitive or physical effects, even when the two injuries looked identical on the day of diagnosis. For automobile claims specifically, whether noneconomic damages are available at all can also depend on the applicable tort option and statutory requirements; that analysis applies to a concussion the same way it applies to a more visible injury.
New Jersey's own numbers give some sense of scale. An estimated 12,000 to 15,000 New Jersey residents suffer brain injuries from traumatic events each year, and roughly 175,000 residents currently live with disabilities from traumatic brain injuries, with motor-vehicle crashes and falls among the leading causes.
These figures describe traumatic brain injury broadly, not concussion claims or lawsuits specifically, but they show how often this kind of injury shows up in New Jersey families' lives. A personal injury lawyer can review the medical evidence, financial losses, and accident circumstances to help determine what damages may be relevant to the claim.
Frequently Asked Questions:
Can you still have a case if you didn't see a doctor right away after the accident?
A gap in treatment doesn't automatically end a claim, but it can raise questions about the connection between the accident and the injury, so seeking care as soon as symptoms appear and explaining any delay to a treating provider both matter.
Does a concussion diagnosis from urgent care count the same as one from an emergency room?
Generally, yes. What matters most is the medical documentation itself, not which facility provided it, though follow-up care and a clear diagnosis strengthen the record regardless of where treatment started.
Can a concussion claim include a loss of consortium claim for a spouse?
In some cases, a spouse may have a separate claim for the loss of companionship or support caused by the injured person's condition, though this depends on the specific facts and is evaluated separately from the injured person's own claim.
What happens if the at-fault driver or property owner doesn't have insurance?
New Jersey drivers generally carry uninsured or underinsured motorist coverage that can apply in this situation, and a premises claim without applicable insurance may require pursuing the responsible party directly, depending on what coverage exists.
Can you settle a concussion claim before you've fully recovered?
A claim can be resolved before recovery is complete, but settling early can mean accepting a value that doesn't reflect ongoing or future effects, which is why many claims wait until more is known about how the injury will resolve.
When Symptoms Don't Match What Others See, Brandon J. Broderick, Attorney at Law, Listens
A coworker asks why someone who “looks fine” still can't make it through a full shift, and the person with the concussion doesn't have a good answer, because the injury doesn't show up the way a broken arm does.
Brandon J. Broderick, Attorney at Law, has represented clients through exactly that kind of disbelief, building a case out of medical records and documented symptoms, the kind of evidence a stranger walking by would never see.
