A traumatic brain injury can change everything, including your ability to work, communicate, care for your family, and live the life you had before. These injuries don’t always look serious from the outside, but the damage they cause can be permanent and far-reaching. When someone else’s negligence caused your injury, you have the right to hold them accountable.
At Arias Sanguinetti, our Los Angeles brain injury lawyers represent people who have suffered traumatic brain injuries in car accidents, falls, assaults, workplace incidents, and other situations caused by another party’s carelessness. We understand the medical complexity of these cases and what it takes to demonstrate the full scope of your injuries to an insurance company or jury.
Brain injury cases are rarely straightforward. Insurers routinely dispute severity, challenge future care costs, and argue that symptoms are unrelated to the incident. Having an attorney who understands both the medicine and the litigation strategy behind these claims can make a significant difference in what you recover. Contact our team to talk through your situation at no cost.
What Is a Traumatic Brain Injury?
A traumatic brain injury, or TBI, occurs when an external force disrupts normal brain function. This includes direct blows to the head, violent jolts that cause the brain to move inside the skull, and penetrating injuries. According to the CDC, TBIs contribute to hundreds of thousands of hospitalizations and tens of thousands of deaths in the United States every year, and many more people sustain TBIs that go undiagnosed or undertreated.
TBIs are classified by severity:
- Mild TBI (concussion): Brief loss of consciousness or confusion, often with no visible imaging abnormalities. Symptoms can still be disabling and long-lasting.
- Moderate TBI: Loss of consciousness lasting minutes to hours, with potential structural damage visible on imaging.
- Severe TBI: Extended unconsciousness or coma, often with significant and permanent neurological damage.
What makes brain injury cases legally complex is the gap between how an injury looks on a scan and how it affects someone’s daily life. A person with a “mild” TBI on paper can suffer debilitating headaches, cognitive impairment, mood disorders, and an inability to work for months or years. These functional impacts need to be clearly documented and presented, both medically and legally, to support the full value of a claim.
Common Causes of Brain Injuries in Los Angeles, CA
Los Angeles’s dense traffic, active construction industry, and urban environment create conditions where brain injuries happen regularly. Some of the most common scenarios we see include:
- Motor vehicle accidents are the leading cause of TBIs in adults under 75. High-speed collisions, rideshare accidents, motorcycle crashes, and pedestrian knockdowns can all produce significant head trauma, even when airbags deploy or helmets are worn.
- Slip and fall accidents are the leading cause of TBIs overall, particularly among older adults. Wet floors, broken pavement, inadequate lighting, and poorly maintained stairways on someone else’s property can all give rise to premises liability claims.
- Workplace accidents in construction, warehousing, and other physical industries frequently involve head trauma from falling objects, falls from height, or equipment malfunctions. These cases may involve both a workers’ compensation claim and a third-party personal injury lawsuit.
- Assault and violence can cause serious TBIs, including cases where a property owner’s negligence, such as inadequate security, contributed to the incident.
- Sports and recreational injuries at gyms, schools, or recreational facilities may create liability if supervision, equipment, or facility maintenance was inadequate.
Regardless of how a brain injury occurs, the legal analysis centers on who was responsible and what damages resulted. Our personal injury attorneys in Los Angeles evaluate the full picture—liability, insurance coverage, and the long-term cost of your injury—before pursuing any claim.

The Medical Reality of TBI: Why an Accurate Brain Damage Diagnosis Matters
One of the most damaging assumptions in brain injury cases is that a normal CT scan or MRI means the injury isn’t serious. That’s not how brain injuries work, and it’s a point we address directly in litigation.
Many TBIs, especially concussions and diffuse axonal injuries, do not show up on standard imaging. The physical damage occurs at the microscopic level, affecting neural pathways and communication between brain regions. Symptoms like memory loss, difficulty concentrating, emotional dysregulation, fatigue, and sensitivity to light and sound are real neurological consequences that may not be visible on a scan.
This is why diagnostic workup in serious TBI cases often involves:
- Neuropsychological testing to measure cognitive function, memory, attention, and processing speed
- Functional MRI (fMRI) or diffusion tensor imaging (DTI) to detect white matter damage invisible to standard imaging
- Neurology and neuropsychiatry evaluations to document functional impairments and long-term prognosis
- Occupational therapy assessments to measure real-world functional limitations
When we build a brain injury case, we work with medical experts who can explain these diagnostic findings in terms that are meaningful to a jury. The goal is to connect the mechanism of injury to the specific neurological damage, and then connect that damage to every way the brain injury has affected your life professionally, personally, and financially.

Damages Available in a Los Angeles, CA Brain Injury Claim
California law allows brain injury victims to recover compensation for the full range of harms caused by someone else’s negligence. Under California Civil Code §3333, injury victims can seek damages that put them in the position they would have been in had the brain injury not occurred. In a TBI case, that typically includes:
- Economic damages
- Emergency room and hospital care
- Neurology, neuropsychology, and rehabilitation costs
- Future medical treatment and long-term care needs
- Lost wages from time missed at work
- Diminished earning capacity if the injury affects your ability to work long-term
- In-home care and assistance with daily activities
- Non-economic damages:
- Physical pain and suffering
- Emotional distress and psychological harm
- Loss of enjoyment of life
- Cognitive and personality changes
- Impact on relationships, including loss of consortium for a spouse
Brain injuries often produce some of the highest non-economic damage values in personal injury cases because their effects are pervasive and permanent. Accurately quantifying future losses, including lifetime care costs, lost earning potential, and the value of permanent cognitive impairment, requires expert testimony from economists, life care planners, and medical specialists.
In cases involving extreme recklessness or intentional conduct, punitive damages may also be available. A brain injury attorney can assess whether the facts of your case support that type of claim.

How Traumatic Brain Injury Cases Are Investigated and Built
Brain injury claims require a different level of investigation than a routine fender-bender. The evidence needed to prove both liability and the full extent of damages is extensive, and a delay in gathering it can hurt your case. From the moment we take a case, our team works to:
- Preserve physical evidence. In accident cases, this means securing surveillance footage, vehicle data recorders, photographs, and accident reconstruction reports before that evidence disappears. In premises cases, it means documenting the condition of the property and identifying prior complaints or incidents.
- Obtain and analyze complete medical records. We review records from the moment of a severe brain injury through current treatment to identify every diagnostic finding, note every symptom, and build a complete timeline that ties the injury to the accident.
- Retain qualified medical experts. We work with neurologists, neuropsychologists, life care planners, and vocational experts who can provide credible, well-documented opinions about the nature of the injury and its long-term consequences.
- Document the human impact. Beyond medical records, we gather testimony from family members, friends, coworkers, and employers who can speak to how the injury has changed the person we’re representing. This real-world evidence is often as persuasive as the clinical data.
- Challenge insurer tactics. Insurance companies frequently hire their own neuropsychologists to conduct abbreviated testing and produce reports minimizing your injuries. We anticipate those tactics and prepare to counter them with stronger evidence.
Why Los Angeles, CA Brain Injury Cases Are Legally Complex
Not every personal injury attorney is equipped to handle traumatic brain injury litigation. These cases sit at the intersection of medicine, economics, and law in ways that demand a particular depth of preparation.
First, causation is always contested. Insurers will argue that pre-existing conditions—prior head injuries, depression, learning disabilities, or simply normal aging—explain your symptoms rather than the accident. Responding to those arguments requires a thorough understanding of the medical literature and expert witnesses who can explain why the accident, not some other factor, caused or significantly worsened your condition.
Second, damages calculations are complex and high-stakes. Quantifying the lifetime cost of a moderate or severe traumatic brain injury, including medical care, lost earnings, in-home assistance, and non-economic harm, can produce damage estimates in the millions of dollars. Those figures must be grounded in credible expert analysis to survive cross-examination.
Third, insurance coverage issues can complicate recovery. When a traumatic brain injury is caused by a car accident, multiple insurance policies may be involved—the at-fault driver’s liability coverage, your own uninsured/underinsured motorist coverage, and potentially umbrella policies. In premises cases, commercial and residential property insurance may apply. In workplace cases, both workers’ compensation and third-party liability may be available. Identifying and pursuing all available coverage is a critical part of maximizing recovery.
These are not cases where a general approach is sufficient. View our personal injury results to see how we’ve handled high-value injury claims.

Los Angeles Brain Injury FAQ
Here are some answers to the questions we receive most often regarding brain injury claims in Los Angeles.
How Long Do Brain Injury Victims Have to File a Brain Injury Lawsuit in Los Angeles?
California’s statute of limitations for most personal injury claims is two years from the date of injury. There are exceptions, including cases involving minors, government entities, or delayed discovery of the injury, but the safest approach is to consult a traumatic brain injury attorney as soon as possible. Waiting too long can permanently bar your right to recover.
What if I Was Partly at Fault for the Accident that Caused My Brain Injury?
California follows a system of pure comparative fault, which means you can still recover damages even if you were partially responsible for the accident. Your total recovery is reduced by your percentage of fault. For example, if you were found 20% at fault and your damages totaled $1 million, you would recover $800,000.
Can I File a Claim if My Brain Injury Doesn’t Show Up on a CT Scan or MRI?
Yes. Many serious TBIs are not visible on standard imaging, particularly concussions and diffuse axonal injuries. A normal scan does not mean you don’t have a compensable injury.
Neuropsychological testing, functional imaging, and physician testimony can document the real neurological impact even when standard imaging appears normal.
What Is the Average Settlement for a Brain Injury Case in Los Angeles?
No average meaningfully applies to individual cases. TBI settlements vary enormously based on injury severity, long-term prognosis, lost earning capacity, available insurance coverage, and liability facts. Severe TBIs with permanent cognitive impairment and high future care costs can result in multi-million dollar recoveries, while more moderate cases vary based on the specific factors involved.
What Should I Do Immediately After Suffering a Severe Head Injury in Los Angeles?
Seek emergency medical care right away, even if symptoms seem mild. Many serious brain injuries have delayed symptom onset. Document your symptoms in a journal, follow all medical recommendations, and avoid discussing the incident on social media. Contact an experienced brain injury attorney before giving any recorded statements to insurance companies.
Can the Family Seek Compensation for a Loved One’s Brain Injury?
In California, family members may have their own claims depending on the circumstances. A spouse can pursue a loss of consortium claim for the impact on their relationship and household. If a head injury victim is incapacitated, a family member may also be able to bring claims on their behalf as a guardian or through a conservatorship. In fatal TBI cases, the surviving family may pursue a wrongful death claim.
Do I Need an Expert Witness to Win a Brain Injury Case in Los Angeles?
In most serious TBI cases, yes. Expert testimony from neurologists, neuropsychologists, life care planners, and vocational economists is typically essential to proving both the nature of the injury and the full scope of damages. Insurance companies routinely use their own experts to minimize claims, so having credible, well-prepared expert witnesses on your side is critical.
How Does Working with a Los Angeles Brain Injury Lawyer on Contingency Work?
On a contingency fee basis, you pay no upfront legal fees. The attorney’s fee is a percentage of the recovery, only collected if the case is successful. Case costs, such as expert fees, investigation costs, and filing fees, are typically advanced by the law firm and reimbursed from the settlement or verdict. You can discuss the specific fee structure during your free consultation.
