Long Island Concussion Lawyer

A concussion is not a minor inconvenience. It is a traumatic brain injury, and when one is caused by someone else’s negligence, the consequences can follow a person for months or years in ways that are not always visible on a scan or immediately apparent in the emergency room. Headaches, cognitive fog, light sensitivity, memory disruption, mood changes, and disrupted sleep are all real, documented symptoms of post-concussion syndrome, and they can cost a person their job, their relationships, and their sense of themselves. When a Long Island concussion lawyer takes on one of these cases, the work is not just about proving that an impact occurred. It is about demonstrating the full scope of what that injury has taken from a real person.

Long Island presents a specific landscape for concussion injuries. The volume of traffic on the Long Island Expressway, Northern State Parkway, and Sunrise Highway generates a high rate of motor vehicle collisions. Construction along major corridors from Nassau County through Suffolk County puts workers in daily contact with conditions that can produce head injuries. Slip and fall incidents in retail centers, parking lots, and older building stock across communities from Hempstead to Huntington are consistently among the most underreported causes of traumatic brain injury. Nassau and Suffolk County courts handle these cases regularly, and understanding how those courts approach damages for neurological injuries matters enormously to the outcome.

Pursuing compensation for a concussion injury is more complicated than it might appear. Insurance carriers routinely minimize these claims by pointing to the absence of findings on standard imaging, arguing that a “normal” CT scan means the injury is not serious. That argument ignores how concussions actually work. The damage is functional and neurochemical, not always structural, and documenting it properly requires a coordinated approach involving medical records, neuropsychological testing, and expert testimony. An attorney who has handled brain injury claims understands how to build that case from the ground up.

What Causes Concussion Injuries Across Long Island

• Motor vehicle accidents: Rear-end collisions and high-speed impacts on the Long Island Expressway, Jericho Turnpike, and Merrick Road are among the most common causes of concussion on the island, often producing whiplash forces that cause the brain to shift inside the skull without any direct blow to the head.
• Construction and workplace accidents: Workers on Long Island’s active construction sites face risks from falling objects, scaffolding collapses, and falls from elevation. These incidents frequently produce traumatic brain injury, and injured workers may have both a workers’ compensation claim and a third-party personal injury claim depending on who controlled the work site.
• Slip and fall accidents: Wet floors, uneven pavement, broken curbs, and icy surfaces in Nassau and Suffolk County shopping centers, apartment complexes, and municipal properties cause thousands of falls annually. Property owners have a legal duty to maintain safe conditions, and when they fail, they can be held liable for resulting head injuries.
• Sports and recreational injuries: Long Island has a dense youth and adult sports culture, and contact sports injuries at schools, recreation centers, and private athletic facilities can give rise to liability claims when negligent supervision, inadequate equipment, or unsafe conditions contribute to the concussion.
• Pedestrian and bicycle accidents: Cyclists and pedestrians struck by vehicles in communities like Garden City, Massapequa, and Bay Shore have no structural protection against impact. Head injuries in these incidents are often severe even at relatively low vehicle speeds.
• Medical malpractice: A concussion that is misdiagnosed or improperly managed by a treating physician, urgent care provider, or emergency department can be made significantly worse. If a healthcare provider failed to meet the applicable standard of care in evaluating or treating a head injury, that failure may give rise to a separate malpractice claim.

Why Mark David Shirian P.C. Handles Concussion Claims Differently

Mark David Shirian P.C. was founded with a single purpose: to represent people who have been wronged. The firm’s approach is built on close attention to the specific facts of each client’s situation before any strategy is developed. Attorneys Mark D. Shirian and Shawn D. Shirian work directly with clients throughout the process, not through layers of case managers or paralegals who rotate through files. Client reviews of the firm consistently highlight that the attorneys fight hard and keep clients genuinely informed about what is happening with their cases, which matters enormously when someone is managing a brain injury and trying to make sense of a legal system at the same time.

The firm has recovered millions on behalf of injured clients across New York. For a concussion case, that track record is relevant because these claims require the kind of sustained, detail-oriented advocacy that separates a modest settlement from full compensation. Insurance companies know which firms will push a case to trial if necessary, and that knowledge affects what they put on the table during negotiation. Mark David Shirian P.C. has been recognized for its work on high-profile cases and has been featured in the news for results that demonstrate genuine courtroom capability. For someone dealing with the cognitive and emotional aftermath of a traumatic brain injury, having attorneys who treat the case as seriously as the injury demands is not a small thing.

What to Do After a Concussion Caused by Someone Else’s Negligence

The first and most important step is obtaining a thorough medical evaluation, not just an emergency room assessment. Emergency departments are equipped to rule out hemorrhage and skull fracture, but they are not designed to fully assess post-concussion syndrome. Follow up with a neurologist, a neuropsychologist, or a brain injury specialist. In Nassau County, Winthrop University Hospital, Long Island Jewish Medical Center, and Stony Brook University Hospital all have neurology resources. In Suffolk County, Northwell Health’s network provides additional access to specialist evaluation. Document every symptom, every appointment, and every way the injury is affecting your daily life. Journals, medical records, and documentation from your employer about missed work all become part of the evidentiary foundation for your claim.

Report the incident to the appropriate parties promptly. If it was a car accident, a police report filed with Nassau or Suffolk County law enforcement creates an official record. If it was a slip and fall, notify the property owner or manager in writing. If it occurred at a workplace, file the required workers’ compensation report with your employer. Delaying notification or failing to create a formal record can complicate your claim later when liability is disputed.

New York’s statute of limitations for personal injury claims is generally three years from the date of injury, but there are important exceptions. Claims against government entities, including municipalities that own or maintain roads, sidewalks, or public property where the injury occurred, require a notice of claim to be filed within 90 days and then a lawsuit within a shorter window. If your concussion happened because of a defective condition on a county road or a municipal sidewalk in a town like Oyster Bay, Brookhaven, or Islip, missing the notice of claim deadline can permanently bar your recovery regardless of how strong your case is. This is one of the most common and costly mistakes people make when they try to handle a brain injury claim without legal guidance.

Be cautious about communications with insurance adjusters before speaking with an attorney. Recorded statements given in the days or weeks after a concussion, when your cognition may still be impaired, can be used to undermine your claim. You are not legally required to give a recorded statement to the opposing party’s insurance company, and doing so without legal guidance is rarely in your interest.

Damages in a Long Island Concussion Injury Case

One of the central challenges in concussion litigation is that the financial impact of the injury is often larger than it appears at first. Medical expenses include not just the initial emergency visit but ongoing neurology appointments, neuropsychological testing, vestibular therapy, cognitive rehabilitation, and in post-concussion syndrome cases, potentially years of specialized treatment. Lost wages cover time missed from work during recovery, but they also extend to diminished earning capacity if the injury has affected cognitive function in a way that limits a person’s ability to perform their prior job. For professionals, executives, or anyone whose work depends on sustained concentration, memory, or mental processing speed, even a moderate cognitive deficit can have a serious financial consequence.

Non-economic damages, including pain and suffering, emotional distress, and loss of enjoyment of life, are available in New York personal injury cases and often represent a significant portion of the total recovery in concussion claims. Because these injuries are not visible in the way a broken bone is, demonstrating their real impact requires evidence: testimony from family members and coworkers about changes in personality and function, expert opinion from treating physicians and neuropsychologists, and a detailed account from the injured person about what has changed since the injury. A Long Island concussion attorney who has handled traumatic brain injury cases understands how to present this picture compellingly to an insurance company, a mediator, or a jury.

Questions About Concussion Claims on Long Island

How is a concussion legally different from other brain injuries in a personal injury case?

From a legal standpoint, a concussion is a form of traumatic brain injury and is treated as such in New York courts. The challenge compared to more severe brain injuries is that concussions rarely produce visible findings on standard imaging like a CT scan or basic MRI. This requires a different evidentiary strategy, one that relies heavily on functional testing, documented symptoms, expert medical testimony, and evidence of real-world impact on the injured person’s life and work.

What if I did not lose consciousness? Can I still have a valid concussion claim?

Yes. Loss of consciousness is not required for a concussion diagnosis, and it is not required for a personal injury claim based on a concussion. Many concussions involve no loss of consciousness at all. What matters legally is whether the injury was caused by someone else’s negligence and whether you can document the resulting symptoms and their impact. A neuropsychologist or neurologist can evaluate cognitive function and provide medical opinions that do not depend on whether you blacked out at the moment of impact.

The insurance company says my CT scan was normal. Does that end my case?

No. A normal CT scan is not evidence that a concussion did not occur. Standard CT imaging is designed to detect structural abnormalities like bleeding or skull fracture. It does not detect the neurochemical and functional changes that define a concussion. Insurance carriers frequently cite normal imaging to minimize claims, but this argument can be countered with neuropsychological testing results, functional MRI when indicated, documented symptom records, and expert medical testimony explaining how concussions actually present neurologically.

How long does post-concussion syndrome typically last, and how does that affect my case?

Most concussion symptoms resolve within a few weeks to a few months, but a meaningful percentage of people, particularly those who suffered more severe impacts or did not receive proper initial management, develop post-concussion syndrome with symptoms lasting six months or longer. Chronic post-concussion syndrome can last years and include persistent cognitive difficulties, chronic headache, depression, anxiety, and light and noise sensitivity. When a case involves long-term or permanent impairment, the damages calculation changes significantly, and the value of the claim increases accordingly.

Can I bring a concussion claim if I was partially at fault for the accident?

New York follows a pure comparative negligence rule, which means you can recover compensation even if you were partially at fault for the incident that caused your concussion. Your recovery is reduced by the percentage of fault attributed to you, but it is not eliminated unless you are found to be entirely responsible. If, for example, you were found to be 20 percent at fault for a car accident on the Southern State Parkway, you would still be eligible to recover 80 percent of your total damages from the other responsible parties.

My concussion happened at work. Do I have to go through workers’ compensation only, or can I also sue?

Workers’ compensation is generally the exclusive remedy against your employer for a workplace injury, but third-party liability claims are a separate matter. If your concussion was caused by a contractor, equipment manufacturer, property owner, or another party other than your direct employer, you may have a personal injury claim against that third party in addition to your workers’ compensation claim. On Long Island construction sites in particular, where multiple contractors and subcontractors often share a single work zone, third-party liability angles are worth examining carefully.

What if my concussion was made worse by a doctor who failed to properly diagnose or treat it?

This scenario can give rise to a medical malpractice claim layered on top of the original personal injury claim. If a treating physician, emergency medicine doctor, or urgent care provider failed to properly evaluate a head injury, sent you home without appropriate guidance, or missed signs of a more serious underlying injury that should have been identified, that failure may constitute a departure from the standard of care. These claims require medical expert support and a careful review of the treating records, but they are legally viable and can significantly expand the recoverable damages.

How long will my case take to resolve in Nassau or Suffolk County?

The timeline varies considerably depending on the severity of the injury, the complexity of the liability question, and whether the case settles or goes to trial. Nassau County Supreme Court and Suffolk County Supreme Court both have active personal injury dockets. If a case proceeds to trial, it is not unusual for the full process from filing through verdict to take two to three years. Settlement negotiations can resolve cases earlier, but it is rarely wise to settle a concussion case before the full extent of the injury and recovery trajectory is medically established. Settling too early can lock in a number that does not account for long-term or permanent impairment.

What documentation helps most in a Long Island concussion claim?

The most useful documentation includes complete medical records from all treating providers starting from the day of the incident, neuropsychological testing results showing cognitive deficits, a symptom diary maintained in the weeks and months following the injury, records from your employer showing missed work days and any accommodations you needed, statements from people in your daily life who can describe changes in your behavior and function, and any written reports from accident reconstruction experts or safety specialists if liability is contested. The more thoroughly the injury and its consequences are documented in real time, the stronger the foundation for the claim.

Do concussion cases always go to trial on Long Island?

The vast majority of personal injury cases, including concussion claims, resolve before trial through negotiated settlement. However, the outcome of those negotiations is often shaped by whether the opposing insurance carrier believes the attorney is willing and capable of taking the case to verdict. Attorneys who have a demonstrated ability to try cases tend to secure better pretrial outcomes because the other side cannot assume the case will settle on unfavorable terms. Whether a case ultimately goes to trial depends on whether the settlement offers genuinely reflect the value of the claim.
