Understanding Traumatic Brain Injuries Due to Negligence

A traumatic brain injury (TBI) can happen in an instant — and its effects may last a lifetime. When someone else’s carelessness or reckless behavior causes a blow or jolt to your head, the result is not just a medical emergency. Traumatic brain injuries due to negligence leave victims facing staggering medical bills, long-term rehabilitation, permanent cognitive impairment, lost earning capacity, and a fundamentally altered quality of life. Attorney Brett J. Nomberg, of the Law Office of Brett J. Nomberg, PLLC, at 600 Third Avenue, New York, NY, has represented TBI victims in New York for more than 30 years. He knows how to build the medical, economic, and legal record that produces full compensation — and he is available 24 hours a day, 7 days a week to take your call.

The scale of the TBI crisis in the United States is staggering. The CDC reports approximately 214,110 TBI-related hospitalizations and 69,473 TBI-related deaths in the United States in a single recent year — representing more than 586 hospitalizations and 190 deaths every single day. An estimated 2.5 million traumatic brain injuries occur in the United States annually, and over 5.3 million Americans are currently living with a TBI-related disability. Falls and motor vehicle crashes are the two leading causes of TBI hospitalizations and deaths. The vast majority of these injuries are preventable — which means the vast majority of traumatic brain injuries due to negligence should never have happened at all.

In New York, traumatic brain injuries due to negligence are governed by the state’s personal injury and tort framework under CPLR §214, New York Insurance Law §5102(d), and — where a vehicle is involved — the no-fault insurance system under Insurance Law §5103. To file a personal injury lawsuit for a TBI caused by another party’s negligence, your injury must either meet the serious injury threshold under Insurance Law §5102(d) — which TBIs almost always satisfy — or you must pursue a non-vehicle negligence claim outside the no-fault framework. If a government entity contributed to the accident, a Notice of Claim must be filed within 90 days under General Municipal Law §50-e. The standard statute of limitations for personal injury TBI claims is three years from the date of injury under CPLR §214. For fatal TBI cases pursued as wrongful death, the deadline is two years under EPTL §5-4.1. Missing these deadlines forfeits your right to compensation entirely.

What Is a Traumatic Brain Injury?

A TBI occurs when an external force injures the brain — from a direct blow, a violent jolt, or a penetrating wound. TBIs are classified by severity, but even mild TBIs can produce permanent consequences when undiagnosed or undertreated. Traumatic brain injuries due to negligence span the full severity spectrum, from mild concussions suffered in slip and fall accidents to severe, life-altering injuries caused by high-speed vehicle crashes or falls from construction scaffolding. According to the Brain Injury Association of America (BIAA), TBI is the leading cause of death and disability among children and young adults in the United States. Common symptoms of a TBI include:

• Cognitive issues: memory loss, confusion, difficulty concentrating, slowed processing speed
• Physical signs: persistent headaches, dizziness, blurred vision, balance problems, nausea, and fatigue
• Emotional and behavioral changes: mood swings, irritability, depression, anxiety, and personality changes
• Sensory problems: light or noise sensitivity, ringing in the ears (tinnitus), altered sense of taste or smell
• Sleep disturbances: insomnia, hypersomnia, or disrupted sleep-wake cycles — common even in “mild” TBI cases

Even a “mild” TBI — a classification based on the initial injury mechanism, not long-term outcome — can trigger lasting headaches, chronic sleep disturbances, cognitive fog, and personality changes that affect employment and relationships for years. When these symptoms follow traumatic brain injuries due to negligence, every dollar of medical and rehabilitative cost, every lost workday, and every diminishment in quality of life is a recoverable legal damage. For a deeper look at the medical dimensions of TBI, the National Institute of Neurological Disorders and Stroke (NINDS) provides extensive research and patient education resources.

How Negligence Leads to Traumatic Brain Injuries

Negligence is the legal theory that holds a person or entity responsible when they fail to exercise the degree of care that a reasonable person would have exercised under the same circumstances, and that failure directly causes harm to another person. Traumatic brain injuries due to negligence arise across a wide range of accidents — but they all share the same four-element legal structure that must be proven to establish liability and recover compensation:

• Duty of Care: The at-fault party owed you a legal responsibility — for example, every driver must obey traffic laws and drive with reasonable care; every property owner must maintain their premises in a reasonably safe condition; every construction site owner and general contractor must provide adequate fall protection under New York Labor Law §240
• Breach: They violated that duty — speeding, running a red light, leaving a wet floor unmarked, failing to install scaffold guardrails, or ignoring a known hazard
• Causation: Their breach of duty directly caused your traumatic brain injury — proven through medical records, imaging, accident reconstruction, and expert testimony establishing the specific mechanism of injury
• Damages: You suffered real, compensable losses — emergency medical costs, hospitalization, imaging, rehabilitation, lost wages, diminished future earning capacity, pain, suffering, and permanent disability

New York follows a pure comparative negligence rule under CPLR §1411, which means that even if you were partly at fault for the accident, you can still recover — your damages are reduced by your percentage of fault but not eliminated. For example, if you were found 20% at fault and your total damages were $1 million, you would recover $800,000. In traumatic brain injuries due to negligence cases, insurers routinely attempt to assign comparative fault to the injured person. Brett Nomberg fights these arguments aggressively.

Common Causes of Traumatic Brain Injuries Due to Negligence

The most common scenarios giving rise to traumatic brain injuries due to negligence in New York include a range of accidents across vehicle crashes, premises liability, workplace incidents, and products liability. Understanding which legal theory applies to your accident determines which parties you can sue and what evidence is needed to prove your case.

Accident Type	Common Negligent Acts	Applicable Legal Theory	Key Evidence
Motor vehicle crashes	Distracted driving, speeding, DWI, failure to yield, running red lights	Negligence; no-fault / serious injury threshold (Insurance Law §5102(d))	Police report, cell records, dashcam footage, toxicology, EDR data
Pedestrian knockdowns	Driver failure to yield at crosswalk; speeding in school zones; distracted driving	Negligence; serious injury threshold easily met with TBI	Traffic camera footage (overwritten in 24–72 hours), witness statements, NYPD report
Slip and fall / trip and fall	Unmarked wet floor, broken stairs, uneven pavement, inadequate lighting	Premises liability negligence; Labor Law §200 if on job site	Incident report, surveillance footage, prior complaints, maintenance records
Construction site falls	Missing guardrails, unsecured ladder, scaffold collapse, falling tools	Labor Law §240 (absolute liability), §241(6), §200	OSHA records, DOB violations, job site photographs, witness statements
Struck-by accidents (construction)	Unsecured overhead tools or debris, crane load drop	Labor Law §240 (gravity-related), §241(6)	Job site safety plan, OSHA inspection records, equipment logs
Defective products	Defective helmet, airbag failure, faulty power tool	Products liability (strict liability, negligence, or breach of warranty)	Product defect analysis, manufacturer’s testing records, EDR data
Bicycle crashes	Dooring, failure to yield, turning across bike lane	Negligence; NYC Vision Zero enforcement data	Police report, dashcam, bike lane camera footage, witness statements
Sports and recreational negligence	Unsafe playing fields, faulty playground equipment, unmaintained trails, inadequate supervision	Premises liability; negligent supervision; assumption of risk defenses contested	Maintenance records, prior incident reports, municipal or park authority liability
Medical malpractice	Surgical error causing brain damage, failure to diagnose stroke or hemorrhage, anesthesia error	Medical malpractice (different 2.5-year statute of limitations)	Hospital records, surgical notes, expert medical testimony on standard of care
Assault / intentional acts	Physical attack causing head trauma; negligent security allowing assault on premises	Intentional tort + negligent security premises liability	Criminal records, security camera footage, prior incident history at location

Traumatic Brain Injuries Due to Negligence — TBI Severity Classifications

Not all traumatic brain injuries due to negligence present the same way — and the classification of injury severity directly affects diagnosis, treatment, long-term prognosis, and the scope of legal damages available. Courts and medical experts use the following classification framework, based on the Glasgow Coma Scale (GCS), post-traumatic amnesia duration, and loss of consciousness:

TBI Severity	GCS Score	Loss of Consciousness	Common Outcomes	Meets NY Serious Injury Threshold?
Mild (concussion)	13–15	Brief or none; 0–30 minutes	Headaches, cognitive fog, sleep disruption; often resolves but may persist	Possible — if 90/180-day disability or permanent limitation documented
Moderate	9–12	30 minutes to 24 hours	Memory impairment, behavioral changes, partial recovery; may require long-term care	Yes — permanent limitation or significant disfigurement typically present
Severe	3–8	More than 24 hours; coma possible	Permanent disability, personality changes, loss of function, need for full-time care	Yes — always meets threshold; highest damage awards
Penetrating TBI	Varies	Varies; often fatal	Severe focal deficits, paralysis, death; common in high-violence or projectile incidents	Yes — virtually always; wrongful death claims common

Traumatic Brain Injuries Due to Negligence | Your Legal Rights and Protections in New York

Under New York personal injury and tort law, victims of traumatic brain injuries due to negligence are entitled to full compensation for all losses — economic and non-economic — flowing from the injury. New York’s pure comparative negligence system ensures that even a partially-at-fault victim can recover. The following categories of damages are available in traumatic brain injuries due to negligence claims in New York:

• Medical expenses (past and future): Emergency room costs, CT scans and MRIs, neurosurgery, hospitalization, physical and cognitive rehabilitation, prescription medications, neuropsychological therapy, and all future care costs projected over the victim’s lifetime
• Lost wages and lost earning capacity: Income lost during recovery, and — for severe TBIs — the full present value of future earning capacity if the victim can no longer work or must work in a diminished capacity
• Pain and suffering: Compensation for physical pain, emotional distress, and the subjective suffering caused by the TBI — recoverable without a statutory cap in New York personal injury cases outside the workers’ comp system
• Reduced quality of life / loss of enjoyment: Compensation for the activities, relationships, and experiences the victim can no longer enjoy due to the TBI
• Future care and assistive needs: Life care plans prepared by expert vocational and medical specialists — including costs for home aides, occupational therapy, assistive devices, and necessary home modifications
• Wrongful death damages: When traumatic brain injuries due to negligence are fatal, the victim’s family may recover funeral expenses, loss of financial support, and loss of parental guidance through a wrongful death claim under EPTL §5-4.1

New York’s statute of limitations for personal injury TBI claims is three years from the injury date under CPLR §214. Medical malpractice TBI claims carry a shorter 2.5-year deadline. If a government entity caused or contributed to the accident — including the City of New York, MTA, NYCHA, or any municipal agency — a Notice of Claim must be filed within 90 days under General Municipal Law §50-e, and the lawsuit must be filed within one year and 90 days. For minor victims, the statute is tolled under CPLR §208 until age 18, giving them three years from their 18th birthday to file. Do not assume you know your deadline — contact Brett Nomberg to confirm the exact timeline for your specific case.

The Medical Evidence That Proves a TBI Negligence Claim

Winning a traumatic brain injuries due to negligence case in New York requires more than a diagnosis — it requires building a complete evidentiary record that connects the negligent act to the brain injury, quantifies the injury’s severity, documents the full scope of past and future damages, and forecloses the defense’s attempts to deny causation or minimize the injury’s impact. Brett Nomberg works with neurologists, neuropsychologists, life care planning experts, and vocational rehabilitation specialists to assemble this record. Key medical evidence in TBI negligence cases includes:

• Emergency room records: The first medical record following the accident — documents the initial presentation, mechanism of injury, GCS score, and initial imaging findings
• CT scans and MRI imaging: Objective evidence of hemorrhage, contusion, diffuse axonal injury, or structural brain damage. Normal initial imaging does not rule out TBI — Brett Nomberg ensures follow-up imaging is ordered when symptoms persist
• Neuropsychological testing: Standardized battery tests measuring memory, attention, processing speed, executive function, and emotional regulation — translating subjective symptoms into objective, quantifiable impairment scores admissible in court
• Neurologist and neurosurgeon reports: Specialist documentation of diagnosis, prognosis, and functional limitations that directly address the serious injury threshold under Insurance Law §5102(d)
• Psychiatric and behavioral health records: Documenting depression, anxiety, PTSD, and personality changes — non-economic damages that are often the largest component of TBI cases
• Life care plan: A comprehensive expert report projecting all future medical and support costs over the victim’s lifetime — the foundation of future damages in severe TBI cases

Key Steps to Take After Suffering a TBI Due to Negligence

1. Get immediate medical attention — the same day. Even if you feel “fine” or symptoms are mild, seek emergency evaluation immediately. TBI symptoms — including hemorrhage — can be silent for hours before becoming life-threatening. Same-day medical records are the most critical evidence in traumatic brain injuries due to negligence cases, establishing the direct connection between the accident and the injury.
2. Call 911 and report the accident. Whether a car crash, a fall on someone’s property, or a construction accident, a police or incident report creates an official record of the event, the conditions, and the parties involved. Do not leave the scene without a report number.
3. Document everything at the scene. Photograph the surface where you fell, the vehicle damage, the missing guardrail, the wet floor, the skid marks, and your own visible injuries. Note hazard details — the location of a spill, the condition of a ladder, the position of a traffic signal. Capture witness names and phone numbers before people disperse.
4. Save all records from the beginning. Keep every hospital bill, imaging report, pharmacy receipt, therapy invoice, and out-of-pocket expense from the moment of the injury forward. Retain all correspondence from insurance companies — and do not respond to any requests for recorded statements without speaking to Brett Nomberg first.
5. Maintain a daily symptom journal. Record headaches, memory lapses, mood changes, sleep disruption, and physical limitations every day. This contemporaneous record becomes powerful evidence of ongoing impact and supports non-economic damages claims in traumatic brain injuries due to negligence cases.
6. Do not post on social media. Insurance defense investigators routinely monitor plaintiff social media accounts. A single photograph posted during recovery can be used to argue your injuries are less severe than claimed.
7. Contact Brett Nomberg immediately. Traffic camera footage is overwritten in 24–72 hours. Vehicle event data recorders are reset when a car is repaired. Surveillance tapes loop over. Witnesses become harder to reach. Evidence preservation in traumatic brain injuries due to negligence cases begins the moment you call — not weeks later. Brett is available 24/7 at (212) 808-8092.

Why Traumatic Brain Injuries Due to Negligence Require an Experienced New York Attorney

Traumatic brain injuries due to negligence are among the most complex and highest-value personal injury cases in New York. Insurers and defense lawyers fight these claims aggressively — disputing causation (“the accident wasn’t severe enough to cause a TBI”), denying severity (“your imaging was normal”), and arguing comparative fault (“you weren’t wearing a seatbelt / helmet”). Brett Nomberg has defeated every one of these defenses. He works with neurological experts to establish causation through medical literature on low-impact TBI mechanisms. He commissions neuropsychological testing to document cognitive impairment that does not appear on imaging. He builds life care plans that project lifetime damages with actuarial precision. And he refuses low early offers that do not reflect the full value of his clients’ injuries.

Brett’s record in traumatic brain injuries due to negligence and related catastrophic injury cases speaks for itself. He secured a $4.5 million verdict for a brain injury client — one of the largest results in his 30-year career. He obtained $3.9 million in a case where evidence of the brain injury had been concealed. He recovered $1.7 million in a case where a surveillance tape capturing the accident was hidden. These results are detailed on his verdicts and settlements page. Related practice areas for TBI victims include spinal cord injury, catastrophic injury, construction accidents, pedestrian accidents, car accidents, and products liability.

Traumatic Brain Injuries Due to Negligence — Frequently Asked Questions

Question	Answer
What qualifies as negligence in a TBI case?	Failing to act with reasonable care under the circumstances — speeding, ignoring known hazards, leaving a dangerous condition unmarked, failing to secure a construction work site, or driving under the influence. Any breach of a legal duty of care that directly causes a traumatic brain injury qualifies.
Who can be sued for traumatic brain injuries due to negligence in New York?	Anyone whose careless or reckless conduct caused the injury: drivers, property owners, general contractors, subcontractors, equipment manufacturers, municipalities, employers (in third-party claims), and recreational facility operators — depending on the accident type.
What types of compensation are available for traumatic brain injuries due to negligence?	Economic damages (medical bills, rehabilitation, lost wages, future care costs), non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life), and in cases of especially reckless conduct, punitive damages. There is no statutory cap on compensatory damages in New York personal injury cases.
How long do I have to file a lawsuit for traumatic brain injuries due to negligence in New York?	Three years from the injury date under CPLR §214 for personal injury claims. Medical malpractice TBI claims have a 2.5-year deadline. Wrongful death TBI claims must be filed within two years. Claims against government entities require a Notice of Claim within 90 days. Minor victims have until age 21 (three years from age 18). Always confirm your specific deadline with Brett Nomberg — never assume.
Do I need a lawyer if my TBI symptoms seem minor?	Yes. “Mild” TBI symptoms can escalate dramatically weeks or months after the accident. Early legal advice ensures evidence is preserved before it disappears, deadlines are identified and met, and you do not inadvertently waive rights by giving a recorded statement or accepting a low early offer before the full extent of your injuries is known.
Can I recover if I was partly at fault for the accident that caused my TBI?	Yes. New York’s pure comparative negligence rule under CPLR §1411 allows you to recover even if you were partially at fault. Your total damages are reduced proportionally by your percentage of fault — but not eliminated. Brett Nomberg fights to minimize any fault assigned to his clients.
What if my TBI does not show up on a CT scan or MRI?	Normal imaging does not rule out a TBI. Diffuse axonal injury, post-concussive syndrome, and mild TBI often do not produce visible abnormalities on standard imaging. Neuropsychological testing, functional MRI (fMRI), and DTI scans can document brain injury that standard imaging misses — and Brett Nomberg works with specialists who perform these evaluations.
Can a construction worker file a TBI claim under Labor Law §240?	Yes. If the TBI resulted from a fall from height or a falling object at a construction site, Labor Law §240’s absolute liability applies — meaning the property owner and general contractor are responsible regardless of the worker’s own conduct. This is one of the most powerful legal protections for construction TBI victims.
How are future damages calculated in TBI negligence cases?	Expert life care planners and vocational rehabilitation specialists prepare detailed projections of all future medical care, therapy, assistive needs, and lost earning capacity — discounted to present value. Actuarial life expectancy analysis determines the total lifetime cost. These expert reports form the foundation of future damages demands in severe TBI cases.
What is the serious injury threshold and does a TBI meet it?	Under New York Insurance Law §5102(d), a TBI that causes a fracture, permanent limitation of a body function, significant disfigurement, or a 90/180-day disability meets the threshold. Moderate and severe TBIs almost always qualify. Mild TBIs may qualify if properly documented by a neurologist or neuropsychologist with objective evidence of permanent limitation.
