You walked out of the emergency room after your accident with a stack of discharge papers, a prescription for ibuprofen, and the word “concussion” buried somewhere in the chart, or maybe not mentioned at all. The CT scan was clean. The doctor said to follow up with your primary care if you felt worse. A week later, you cannot focus on a work email for more than five minutes. Two weeks in, you forget your daughter’s soccer game. A month in, you are sleeping twelve hours a night and waking up exhausted. Your spouse mentions the personality changes before you notice them yourself. Traumatic brain injuries that get missed at the ER are some of the most disputed and most consequential cases in New Jersey personal injury practice. At The Law Offices of Anthony Carbone, we have seen this pattern repeat across rear-end collisions, slip and falls, workplace accidents, and assault cases, and the difference between a recognized injury and a missed one usually comes down to how the medical and legal sides are built in the weeks after the initial visit.
Why TBIs Get Missed in the Emergency Room
Emergency rooms are built to identify life-threatening injuries. The standard imaging used to evaluate head trauma after most accidents is a non-contrast CT scan of the head, which is excellent at detecting bleeding, skull fractures, and large mass lesions. The CT is not designed to detect the microscopic damage that characterizes mild traumatic brain injury and post-concussive syndrome.
The injuries that show up on CT are the ones that kill people quickly. The injuries that follow patients home and reshape their lives often look like a normal scan.
Several factors contribute to the under-diagnosis problem:
- ER physicians focus on ruling out catastrophic injury rather than diagnosing subtle neurological dysfunction
- Adrenaline at the time of the injury suppresses cognitive symptoms during the ER evaluation
- Loss of consciousness is brief or absent in many TBI cases, removing one of the classic warning signs
- The Glasgow Coma Scale rates many concussed patients at 15 out of 15
- Patients in pain from other injuries do not register or report cognitive symptoms
- The discharge instructions often mention concussion only in passing if at all
A clean CT and a normal mental status exam at the ER says the patient is not about to die from the head injury. It does not say the brain is undamaged.
What Mild Traumatic Brain Injury Actually Looks Like
The clinical picture of mild TBI develops over hours, days, and weeks. Symptoms can include:
- Headaches that persist or worsen days after the injury
- Difficulty concentrating, reading, or completing tasks at work
- Short-term memory problems and word-finding difficulties
- Sleep disturbances, including both insomnia and excessive sleeping
- Sensitivity to light and sound
- Mood changes, irritability, and depression
- Dizziness, balance problems, and visual disturbances
- Fatigue out of proportion to activity level
Most concussion patients improve within weeks. A meaningful percentage develop post-concussive syndrome that persists for months or years. A smaller group never returns to baseline function, even with treatment.
Why Insurance Carriers Fight These Cases Hard
The defense playbook on missed TBI cases is consistent. Carriers argue that:
- The ER record contains no diagnosis of brain injury
- The CT scan was negative
- The patient did not lose consciousness or did so only briefly
- The symptoms reported later are subjective and unverifiable
- The patient must have had pre-existing depression, anxiety, or attention issues
- The accident was too minor to produce a real brain injury
Each of these arguments has a response, but only when the medical record supports it. The early days after the injury are when the foundation gets built or lost.
The Imaging That Actually Detects Brain Injury
Standard CT is the wrong test for mild TBI. The tools that actually identify subtle brain injury include:
- MRI with diffusion tensor imaging, which can detect white matter damage invisible on standard imaging
- Susceptibility-weighted imaging, sensitive to small bleeds and microhemorrhages
- Functional MRI, which measures brain activity rather than just structure
- Neuropsychological testing, a comprehensive battery administered by a clinical neuropsychologist
- Quantitative electroencephalography in select cases
Neuropsychological testing is often the most useful evidence in a contested TBI case. A two-day battery measures memory, attention, processing speed, executive function, language, and motor coordination. The results are compared against age and education norms to identify specific deficits and quantify them objectively.
A treating neurologist or neuropsychologist building the case from the ground up produces medical evidence that survives the defense IME and stands up at trial.
Building the Treatment Record
The strength of a TBI claim depends on the medical record built in the weeks and months after the injury. The treatment trajectory that supports the case typically includes:
- Prompt follow-up with a primary care physician with documentation of new symptoms
- Referral to a neurologist for evaluation and ongoing care
- Neuropsychological evaluation by a qualified specialist
- Vestibular and balance therapy when dizziness is part of the picture
- Cognitive rehabilitation therapy targeting specific deficits
- Mental health treatment for the depression and anxiety that often accompany TBI
- Return-to-work coordination and accommodations when needed
Gaps in treatment hurt the case. A patient who sees no doctors between week two and month six gives the carrier an argument that the injury resolved and any later symptoms must be from something else. Continuity matters.
The Pre-Existing Condition Question
Defense attorneys will scour the medical record for any prior mention of headaches, depression, ADHD, sleep problems, or cognitive complaints. The presence of pre-existing conditions does not defeat a TBI claim, but it requires the case to be built around the eggshell skull rule, which holds that a defendant takes the plaintiff as found. A person with prior issues who suffers an aggravation or exacerbation can recover for the worsening, and the medical experts need to articulate the distinction clearly.
The Damages in a TBI Case
TBI cases produce damages across categories that other injury cases rarely reach:
- Medical expenses, including past treatment and lifetime future care projections
- Lost wages and diminished earning capacity, often substantial when cognitive function is impaired
- Pain and suffering, including the headaches, sleep disruption, and mood symptoms
- Loss of consortium for the spouse whose partner is no longer the same person
- Loss of enjoyment of activities the plaintiff can no longer perform
- Cost of household services the plaintiff once handled and can no longer manage
Life care planners and vocational economists produce reports quantifying the future costs in cases involving significant cognitive impairment. Those numbers can run into seven figures even in cases that started with a clean CT scan at the ER.
How The Law Offices of Anthony Carbone Builds Missed TBI Cases
The firm’s approach to a TBI case where the ER missed the diagnosis includes:
- Comprehensive review of the ER record, accident scene evidence, and mechanism of injury
- Coordination with primary care and specialist physicians on appropriate follow-up testing
- Retention of treating and consulting neuropsychologists with experience in litigation
- Preservation of accident scene evidence, vehicle damage photos, and biomechanical evidence supporting the force of impact
- Witness statements from family members and coworkers documenting cognitive and behavioral changes
- Preparation for the defense IME and the cross-examination strategies that often follow
The firm’s practice area pages and auto accident coverage include related background. The Brain Injury Alliance of New Jersey at bianj.org publishes resources for patients, families, and professionals working with TBI cases.
A traumatic brain injury that did not show up on the ER scan is not a smaller case than one that did. The medical evidence develops differently and on a longer timeline, but the injury and the damages are just as real and often more disabling. The Law Offices of Anthony Carbone offers a free consultation to evaluate the accident, the symptom history, and the medical workup needed to build the case the right way.
