As Seen On:










Where a Boston brain injury lawyer starts.
A brain injury is among the most serious harms a person can suffer, and it often hides in plain sight. A concussion, a bleed, or a severe traumatic brain injury can change memory, focus, mood, and the ability to work, sometimes permanently. These injuries follow car and truck crashes, falls, being struck by an object, sports, and assaults, and the people around the victim often notice the changes before the victim does. When someone else’s negligence caused the injury, Massachusetts law lets the injured person seek full compensation for the harm.
Because brain injury claims are expensive, insurers often minimize the injury, argue the symptoms are unrelated to the incident, or push a fast, low settlement before the full picture is known. Proving a brain injury takes solid medical evidence, the right experts, and a clear account of how daily life has changed. A Boston brain injury lawyer builds that proof and pursues the lasting cost of the injury, not just the first hospital bill. Larson Law represents brain injury victims throughout Boston and Suffolk County at no upfront cost, and you pay nothing unless we win.
What makes these cases difficult is that the most serious effects are often invisible. A person can look fine and still struggle with concentration, word-finding, irritability, headaches, fatigue, and the ability to hold a job or manage a household. Those effects are real, they are compensable, and proving them takes more than an emergency-room note. It takes treating physicians, neuropsychological testing, and the accounts of family and coworkers who see the difference every day.
A serious brain injury also reaches far into the future. There may be years of therapy, lost earning power, and the need for support at home, and a claim should account for those future costs rather than just the bills already paid. A lawyer handles the insurer and the investigation so you can focus on recovery, and because we work on a contingency fee, getting answers costs you nothing up front.
Brain injuries in the city happen in many ways, and most trace back to someone else’s carelessness. We help people hurt in car, truck, and motorcycle crashes, pedestrians and cyclists struck by drivers, workers injured on construction sites and in warehouses, people who fall on poorly maintained stairs or icy walkways, and victims of assaults. In each, a blow or a violent jolt to the head can cause an injury that does not fully reveal itself for days. Some clients face a long road of rehabilitation; others struggle quietly with memory, concentration, and mood while trying to keep working and caring for their families. Whatever the cause, if another party’s negligence led to the injury, the law gives the victim a way to seek accountability and the compensation needed to move forward, and the only way to know what your case may support is to have it reviewed by a lawyer who handles brain injuries.
Larson Law handles brain injury cases across Boston, and clients from around the state reach the firm as well. A traumatic brain injury is unlike almost any other claim, because the harm is often invisible on the outside and slow to reveal itself. Symptoms can surface days or weeks after the event, and an insurer will seize on any gap between the injury and the first medical note to argue the two are not connected at all. Daniel J. Larson personally reviews how the injury happened, who was responsible, and how it has changed daily life before any claim moves forward. There is no cost to speak with the firm.

How Massachusetts Brain Injury Law Works
Proving someone else caused the injury
A brain injury claim begins by showing that another party was negligent and that their carelessness caused the injury, whether a distracted or speeding driver, a careless property owner, or a business that failed to keep people safe. The injured person must connect that negligence to the harm, which is why prompt medical documentation linking the injury to the event matters so much. The sooner the connection is recorded, the harder it is for an insurer to argue the symptoms came from something else.
Shared fault and the deadline to file
Massachusetts uses comparative negligence, so an injured person can recover as long as they were not more than half at fault, with the award reduced by their share. Most injury claims must be filed within three years, and for an injured child the clock does not start until they turn eighteen. That deadline is harder than it sounds after a head injury, where symptoms can surface long after the event and the connection is only understood later. If a brain injury proves fatal, the family can bring a wrongful death claim instead, which carries its own rules and its own deadline. Claims against a public entity can carry much shorter notice deadlines.
Counting the full, future cost
A serious brain injury can require years of treatment, therapy, and lost earning power, so a claim should account for future costs, not only the bills already paid. Proving that future need takes medical and vocational evidence, including the opinions of treating doctors, neuropsychologists, and life-care planners. It is often where insurers fight hardest, because the future care is where the real value of a serious case lies, and building that proof early protects it.
If the injury happened at work, there may be more than one path. A workplace brain injury usually involves workers’ compensation, but when a third party other than the employer caused the harm, a separate claim against that party can proceed alongside the comp claim. Sorting out which paths apply is part of what a lawyer does at the very start.
We also know how insurers approach these claims, and we are ready for it. They may argue the symptoms come from stress, a prior condition, or normal aging, point to a clean initial scan as if it ends the discussion, or offer a quick settlement before the long-term effects are understood. We answer those tactics with evidence: the imaging, the treating records, neuropsychological testing, and the testimony of people who knew the victim before and after the injury. Because we prepare every case as if it may be tried before a Suffolk County jury, our demands carry the weight of a firm willing to go the distance, which is often what it takes to reach a fair result in a serious brain injury case. Throughout, you pay nothing up front and owe a fee only if we recover for you, so the cost of expert proof never falls on the injured person.
The strength of a brain injury claim often comes down to how completely the injury is documented and explained. We work to capture not just the diagnosis but the day-to-day reality of living with it: the missed work, the help a person now needs at home, the activities and plans that are no longer possible, and the strain on the family. We bring in neuropsychologists to measure the cognitive effects, treating physicians to explain the prognosis, and, where the future care is significant, life-care planners and economists to put a reliable number on what the years ahead will cost. That detailed proof is what separates a claim that is taken seriously from one an insurer can dismiss, and it is the work we do in every serious case at no cost to you unless we win.
Where Boston Brain Injuries Happen
Where brain injuries happen in Boston
Brain injuries in Boston follow crashes on busy roads like Interstate 93, Storrow Drive, and the streets of downtown and the neighborhoods, as well as falls on stairs and worksites, pedestrian and bicycle collisions, sports, and assaults outside the city’s bars and venues. A blow or a violent jolt can cause lasting harm even without a loss of consciousness. However the injury happened, the questions are the same: who was at fault, and how serious is the harm to the person’s brain and their life.
Care and where these claims are handled
Serious head injuries in the area are often treated at Massachusetts General Hospital, Brigham and Women’s Hospital, Boston Medical Center, and Tufts Medical Center, with rehabilitation at Spaulding Rehabilitation Hospital, a national leader in brain injury care. Injury cases tied to Boston are generally handled in the Suffolk County courts, including the Boston Municipal Court and Suffolk Superior Court. A lawyer who knows the local hospitals, the rehabilitation network, and the courts can move quickly to gather records and line up the right medical proof.
Why fast action protects your claim
The proof in a brain injury case is strongest when it is gathered early. Imaging, emergency records, and the first reports of symptoms tie the injury to the event, and witnesses and any video are easiest to secure soon after. Acting early lets your lawyer preserve that evidence, document the baseline of how you have changed, and start the expert work that a serious case needs. Larson Law builds that proof while you focus on recovering, and we never charge anything up front to do it.
Reaching out after a brain injury should be simple, especially when the injured person is still recovering, so we keep the first conversation easy and pressure-free. Call or send a message and a Boston brain injury lawyer will listen to what happened, answer your questions, and explain how a claim works, how the future care is valued, and what the likely next steps are. Family members are welcome to take part, since they often see the changes most clearly. If we take the case, we handle the investigation, the medical proof, and every conversation with the insurer from there, and we keep you informed at each stage. If we do not, you will still leave understanding your rights and your options. Either way the review is free, there is no obligation, and you will never owe us anything unless we win.
If you are unsure whether what happened supports a claim, or the insurer has already reached out, it still costs nothing to find out where you stand. Many families assume too little can be done, only to learn that the evidence clearly points to another party’s negligence and that meaningful coverage is available to pay for the care ahead. The sooner a lawyer reviews the injury, the more of the medical and witness proof can be preserved, and the stronger the claim becomes. Tell us what happened, and we will give you an honest assessment of your options, with no cost and no obligation, so you can make an informed decision for yourself or your loved one.
A brain injury can affect every part of a person’s life, and the right legal help should reflect that. We take the time to understand not just the medicine but the person, so the claim we build tells the full story of what was lost and what recovery will require. If a brain injury has changed your life or your family’s in Boston, we are ready to help you take the first step.
The call is free, your information stays private, and there is never any obligation to hire us after the review.
Proving a brain injury is a matter of building a record, not winning an argument. The strongest cases rest on a chain of qualified opinion, from the treating neurologist to neuropsychological testing and, where needed, a life-care plan that projects the cost of future treatment and support. Fault is still measured by percentage, and the value of a serious brain injury reaches far past medical bills into lost earning capacity and the lasting cognitive and behavioral effects that reshape a life.
Time works against these cases. Most claims must be filed within three years, and the sooner the medical record connects the injury to its cause, the harder it becomes for an insurer to break that link. Because the full picture of a brain injury can take months to emerge, starting early does not mean settling early; it means preserving the evidence and the treatment history that a fair valuation later depends on.
Brain injuries in and around Boston arrive from many directions, a fall on an icy sidewalk or a poorly maintained stairwell, a crash on Storrow Drive or the expressway, a struck-pedestrian collision downtown, or an assault outside a late-night venue. The cause shapes who is responsible and which insurance responds, but the medical path often runs through the city’s major trauma centers, and the records they create become a backbone of the claim. Tying the injury to a specific event, and to a party who owed a duty of care, is where a careful investigation begins.
What a Boston Brain Injury Claim Covers
A brain injury can carry costs that last for years, far beyond the first hospital stay. A claim can cover past and future medical care, rehabilitation and therapy, lost wages and lost earning capacity, pain and suffering, and the lasting toll on daily life and independence. A full claim reflects all of it, including the care a person may need for the rest of their life. When the injury reshapes how someone relates to a spouse or children, the law also recognizes what those closest to the person lose, a real and compensable part of the harm.
A brain injury arrives through many doors. A rider thrown to the pavement, a person struck in a crosswalk, a fall on unsafe stairs, a motorcyclist down on the road, a driver in a violent wreck — the mechanism differs every time, but the questions that follow a head injury do not, and neither does the work of proving one.
Head injuries also reach us from well beyond the city, and families who were hurt in Cambridge, Brockton or Lowell arrive with the same questions. Wherever the injury happened, we are ready to help.

Common Questions After a Boston Brain Injury
How do I know if I have a brain injury claim?
If someone else’s negligence caused a blow or jolt to your head, in a crash, a fall, an assault, or a workplace incident, and you have lasting symptoms, you may have a claim. The clearest sign is that your thinking, mood, or daily function has not returned to normal since the injury.
What counts as a traumatic brain injury?
A traumatic brain injury is any disruption of normal brain function caused by an external force, from a concussion to a severe injury. It does not require a skull fracture or a coma. Even a so-called mild injury can bring lasting problems with memory, focus, mood, and sleep.
What if my symptoms started days later?
That is common and does not weaken your claim. Brain injury symptoms, headaches, confusion, mood changes, and trouble concentrating, often surface hours or days after the event. Getting prompt medical attention and documenting the symptoms as they appear helps connect them to the injury later.
Do I have a claim if I did not lose consciousness?
Yes. Most traumatic brain injuries happen without any loss of consciousness, and the law does not require it. What matters is that a real injury occurred and disrupted how your brain works, not whether you briefly blacked out at the moment of impact.
How do you prove a brain injury?
Through a combination of medical records, imaging where it applies, neuropsychological testing, and the accounts of people who knew you before and after. Because these injuries are not always visible on a scan, the day-to-day changes that family and coworkers observe often become important evidence.
How long do I have to file a claim?
Under G.L. c. 260, §2A, you generally have three years from the date of the injury to file a personal injury claim. Because medical documentation and witnesses are strongest early, and some symptoms take time to surface, it is wise to speak with a lawyer well before that deadline.
What if I was partly at fault?
You can still recover under G.L. c. 231, §85, the state’s comparative negligence rule, as long as your share of fault is not greater than the other side’s. Your award is reduced by your percentage, so how fault is investigated and divided directly affects what you receive.
What is a brain injury claim worth?
It depends on the severity and permanence of the injury, the care and therapy required, the income and earning power lost, and how daily life has changed, not on any formula. Because a brain injury can last a lifetime, the claim often has to account for decades of impact.
What if the injury happened at work?
A workplace brain injury may involve workers’ compensation benefits and, separately, a claim against any party other than your employer whose negligence contributed, such as a contractor or an equipment maker. Pursuing both paths where they apply is part of what a lawyer sorts out early on.
What if a loved one died from the injury?
If a brain injury proved fatal, close family members may bring a wrongful death claim under Massachusetts law for the losses they suffer, including lost support and companionship. Such a claim has its own deadline, and pursuing it can bring both accountability and some measure of stability.
How much does a brain injury lawyer cost?
Nothing up front. These cases are handled on a contingency fee, so you pay no attorney’s fee unless there is a recovery, and the first case review is free. That lets an injured person pursue a complex brain injury claim without worrying about hourly bills.
What should I do right after a head injury?
Get medical care right away, even if the injury seems minor, because brain injuries can worsen and early records matter. Write down symptoms as they appear, keep your appointments, and ask someone you trust to note changes they see. Then speak with a lawyer before giving any statement to an insurer.
