Below, the California trial attorneys at Kalfayan Merjanian, LLP, take a look at the options available, what they allow a caregiver to do, and the practical steps needed to secure and preserve compensation for the injured person. If your loved one suffered a TBI because of another party’s negligence, give us a call to speak with one of our lawyers experienced in representing victims of catastrophic injuries in California.

Injured Minors (under 18)

When a child under 18 years old is injured, their claim is typically brought by a parent or guardian ad litem (GAL) acting as the minor’s representative. A GAL is often appointed in cases where the legal rights of a minor may be affected. The role of the GAL is to represent the minor’s best interests in litigation and settlement.

If both parents are available and acting together, they commonly file suit on the child’s behalf, but the court still oversees settlements to protect the child’s interests. Any settlement of a minor’s personal injury claim by an adult (known as a “minor’s compromise”) typically requires court approval. The court reviews whether the settlement is fair and may order the funds placed in a blocked account or trust for the child.

Custodial status and any existing guardianship can play an important role. If the parents are unmarried, custody questions can affect which parent may sign settlement documents. If in doubt, petitioning for a GAL is the safe route.

Incapacitated Adults

For adults who lack legal capacity due to a TBI, California recognizes several avenues to pursue a claim on their behalf:

• Conservator (Probate conservatorship) — A conservator of the person or the estate appointed under California probate law may bring or defend litigation and can sign settlement documents on behalf of the conservatee. Where long-term incapacity is present, a conservatorship is the principal mechanism for giving someone legal authority to manage money and pursue legal claims.

• Guardian ad litem (GAL) — If an adult is “incompetent” for litigation purposes but has no conservator yet, the court may appoint a GAL to represent the incapacitated person’s interests during the lawsuit. The California Code of Civil Procedure (CCP §372) authorizes the appointment of a GAL for minors and incapacitated adults. This section of the law has been recently updated to clarify when the appointment of a GAL is appropriate.

• Next friend — A “next friend” (often a family member) may initiate litigation on behalf of a minor or incompetent adult when no formal guardian or conservator exists. The next friend is not a party or court-appointed fiduciary, so courts often require a more protective approach, such as the appointment of a GAL or conservator as the case progresses.

How the Type of Representation Affects Settlements and Where the Money Goes

• Minor’s settlements: After court approval, money is generally protected in a blocked account, structured settlement, or trust. Courts supervise attorney fees and disbursements for the child’s benefit.

• Conservatee settlements: The conservator must manage settlement proceeds for the conservatee’s needs, and large sums may require an accounting or approval by the court, depending on local practice. A conservator can also fund a special needs trust or structured settlement to preserve benefits like Medi-Cal or SSI.

• Next friend filings: if a next friend files suit, courts typically move to appoint a GAL or conservator to avoid conflict and ensure the incapacitated person is fully protected.

Practical Roadmap for Caregivers Pursuing Legal Claims

1. Prioritize medical care and documentation. The medical record is the foundation of a personal injury claim, and documents such as ER notes, neurology reports, imaging, rehab plans, therapy notes, and cognitive testing will be instrumental in building a case proving the extent of the injury and its impact on the victim’s life.

2. Preserve evidence. Request and preserve accident reports, photos, surveillance requests, and witness contact info. Send preservation letters for video evidence immediately.

3. Talk to an experienced California personal injury attorney who handles TBI cases. By talking to a TBI lawyer early, you’ll have a better idea of whether you should seek a conservatorship, petition for a GAL, or proceed as next friend to file a claim in a timely manner.

4. If the victim is a minor, expect a guardian ad litem appointment and a minor’s compromise hearing before any settlement funds are distributed.

5. If the victim is an adult and lacks capacity, prepare to file for conservatorship of the person, the estate, or both so that a conservator can file a claim and manage funds. Your attorney can usually file the personal injury claim in parallel with a conservatorship petition.

Why You Need a Lawyer Experienced in TBI Matters

These cases require both medical-legal expertise and procedural skill. A capable attorney will be able to evaluate capacity issues and promptly pursue the correct appointment, such as a GAL or conservator. They know what evidence to preserve and will be sure to file suit within California deadlines, if necessary. A TBI lawyer understands how to work with neurologists, neuropsychologists, and life-care planners to calculate future needs and lifetime costs. They can also advise you on using special needs trusts, structured settlements, or blocked accounts to maintain public-benefit eligibility while ensuring long-term care. A lawyer experienced in representing incapacitated individuals will also know the process for court approvals of a minor’s compromise or conservatee settlement so the funds are protected.

Practical Takeaways for Caregivers

If the injury is temporary and immediate decisions are needed regarding issues like medical care or whether to settle a claim, a temporary conservatorship or GAL petition can be filed quickly. For long-term incapacity, pursuing a full probate conservatorship enables the conservator of the estate to better manage settlement proceeds and supervise ongoing care.

Courts are protective. Even when a conservator signs a settlement, the court often reviews large or unusual settlements to ensure funds are used for the incapacitated person’s benefit. Expect judicial oversight.

Why Motorcycle Accidents Often Lead to TBIs

Motorcyclists are at higher risk of traumatic brain injuries for several reasons:

• Lack of structural protection: Cars and trucks have seat belts, airbags, and reinforced frames, while motorcyclists are largely exposed.
• High-impact collisions: Motorcycle accidents often involve collisions with larger vehicles such as cars and trucks, resulting in a greater force of impact.
• Road hazards: Potholes, debris, wet surfaces, and uneven pavement can cause a rider to lose control and suffer head injuries even without another vehicle involved.
• Falls and ejections: When riders are thrown from a motorcycle, their heads can hit the pavement, guardrails, or other objects.

While wearing a helmet significantly reduces the risk of fatal head injuries, it does not eliminate the possibility of a TBI. Helmets protect the skull but cannot always prevent brain damage caused by the rapid acceleration or deceleration forces experienced in a crash.

Types of Traumatic Brain Injuries Common in Motorcycle Crashes

TBIs vary in severity and type, ranging from mild concussions to severe brain damage. Common types include:

• Concussions: Even a mild concussion can lead to headaches, dizziness, blurred vision, and memory problems. Repeated concussions or delayed treatment can worsen outcomes.
• Contusions: Bruising of the brain tissue can cause swelling, neurological deficits, or permanent impairment.
• Diffuse axonal injuries (DAI): Often caused by rotational forces during a crash, DAI involves widespread damage to brain fibers and can result in prolonged unconsciousness or permanent disability.
• Skull fractures with brain injury: Penetrating trauma or severe impact may fracture the skull and damage the underlying brain tissue.

The effects of a TBI can be temporary or permanent, and they often evolve over time. Some symptoms, such as memory loss or mood changes, may not appear immediately after the accident.

Symptoms to Watch for After a Motorcycle Accident

Even when a motorcyclist is able to walk away from a crash without losing consciousness, any of the following symptoms could indicate a traumatic brain injury:

• Persistent headaches or migraines
• Dizziness, loss of balance, or vertigo
• Nausea or vomiting
• Difficulty concentrating, confusion, or memory problems
• Mood swings, irritability, anxiety, or depression
• Sensory changes, such as blurred vision or ringing in the ears
• Fatigue or sleep disturbances

Because TBIs can worsen if left untreated, it is critical to seek medical evaluation immediately after any motorcycle accident involving head trauma, even if a helmet was worn.

Long-Term Consequences of TBIs

Traumatic brain injuries often lead to significant, long-term consequences that affect a victim’s quality of life. Physical impairments may include chronic headaches, motor difficulties, and balance issues. Cognitive deficits such as memory problems, impaired judgment, or reduced processing speed can interfere with work, school, or daily life. Emotional and behavioral changes, including depression, anxiety, and irritability, are also common.

California law recognizes these long-term impacts in personal injury claims, allowing victims to recover compensation for ongoing medical care, lost earning capacity, pain and suffering, and diminished quality of life. To recover damages for a traumatic brain injury sustained in a motorcycle crash, the injured rider must show that another party was negligent. Common scenarios include car or truck driver negligence; speeding, distracted driving, DUI, or failure to yield are frequent causes of motorcycle crashes. Defective road conditions, such as potholes, debris, or poorly maintained roads, can also contribute to accidents. In some cases, motorcycle defects, including malfunctions in brakes, tires, or other critical components, may lead to a crash.

Evidence in these cases may include accident reports, witness statements, medical records, expert testimony, and, in some cases, surveillance footage. Establishing negligence is critical to securing compensation for the full range of damages accompanying a TBI.

The Importance of Legal Representation

Traumatic brain injuries are complex, and proving the full extent of damages in a motorcycle accident claim can be challenging. Insurance companies often attempt to minimize payouts or blame the rider for the accident. An experienced California personal injury attorney can help investigate the accident and gather evidence, work with medical experts to document the severity and long-term impact of the TBI, accurately calculate economic and non-economic damages, negotiate with insurers, and pursue litigation if necessary. Having a knowledgeable lawyer on your side ensures that your case reflects the true impact of the injury and maximizes the compensation you may receive.

In California personal injury cases, understanding the long-term impact of a brain injury is essential before agreeing to any settlement. Once you accept a settlement, you generally cannot go back to seek additional compensation, even if new symptoms arise or your condition worsens. Read on for a discussion of this critical area, and contact the California trial attorneys at Kalfayan Merjanian, LLP, to speak with a skilled and experienced California traumatic brain injury lawyer. 

Understanding the Nature of a Traumatic Brain Injury 

A TBI occurs when a sudden impact, jolt, or penetrating wound disrupts normal brain function. Even so-called “mild” TBIs, such as concussions, can have serious long-term consequences. Moderate to severe TBIs often cause permanent damage, altering how a person thinks, feels, and functions in daily life. 

Because every brain injury is unique, the long-term effects vary depending on the area of the brain affected, the force of impact, and how quickly the victim receives medical care. Some people recover within weeks, while others face lifelong disability requiring ongoing therapy and support. 

Common Long-Term Physical Consequences 

Many TBI victims experience chronic physical symptoms that persist long after the initial injury. These may include: 

• Chronic headaches or migraines that interfere with concentration and daily activities. 

• Dizziness and balance problems that make walking, climbing stairs, or driving unsafe. 

• Vision and hearing changes, such as blurred vision, sensitivity to light, or ringing in the ears. 

• Seizures or neurological complications, which may develop months after the injury. 

• Sleep disturbances that contribute to fatigue and difficulty functioning. 

These symptoms can severely limit independence and employability. In some cases, victims require lifelong medication or specialized treatment to manage these conditions. 

Cognitive and Memory Impairments 

The brain is responsible for processing, storing, and retrieving information. After a TBI, many victims experience: 

• Memory loss affecting both short-term and long-term recall. 

• Difficulty focusing or multitasking, which can impact work performance. 

• Slowed processing speed, making even routine decisions or conversations challenging. 

• Impaired problem-solving and judgment, affecting independence and safety. 

Because these impairments often develop gradually, victims and their families may not notice their full extent for weeks or months. Accepting a settlement too soon before neuropsychological testing or rehabilitation can leave victims without the financial support needed for long-term care. 

Emotional and Behavioral Changes 

TBIs don’t just affect the body. They can alter personality and emotional regulation. Victims may experience: 

• Irritability or sudden mood swings. 

• Depression or anxiety linked to changes in brain chemistry or lifestyle limitations. 

• Impulsivity or aggression, straining relationships with family and friends. 

• Loss of motivation or interest in activities once enjoyed. 

These emotional effects often create additional challenges for families and caregivers. Some of these changes might not be apparent right away, or they may not be linked to the injury at first. A fair settlement can account for counseling, psychiatric care, and the loss of companionship and emotional stability within the household. 

The Hidden Costs of a TBI 

The true cost of a traumatic brain injury extends beyond medical bills. Many victims cannot return to their previous jobs or must reduce their work hours, leading to lost earning capacity. Others face lifelong rehabilitation, adaptive equipment costs, or home modifications. 

Long-term effects may also include: 

• Chronic pain management requiring specialist care. 

• Cognitive and occupational therapy to restore daily functioning. 

• In-home care or assisted living for those unable to live independently. 

• Transportation and accessibility expenses for disabled victims. 

Because TBIs can have unpredictable recovery paths, it is essential to project future costs before settling. A premature settlement might only cover short-term medical bills, leaving victims without resources for years of ongoing treatment. 

Why You Shouldn’t Settle Too Soon 

After an accident, insurance companies often contact victims quickly with a settlement offer. These offers can be tempting, especially when medical bills are mounting. However, early settlements are designed to limit the insurer’s financial exposure, not to provide full and fair compensation. 

A TBI claim should never be settled until  

• All symptoms have stabilized or reached maximum medical improvement (MMI). 

• Long-term care needs are evaluated by medical experts. 

• Vocational and neuropsychological assessments are completed. 

• Future costs, including therapy, assistive devices, and home modifications, are fully estimated. 

Accepting a settlement too early can permanently forfeit your right to compensation for future expenses and pain and suffering. 

The Role of Expert Testimony in a Brain Injury Case 

In California, proving the full impact of a traumatic brain injury often requires expert testimony. Neurologists, neuropsychologists, and life care planners can explain how the injury affects brain function, employment, and quality of life. Financial experts can project the cost of future medical care and lost earnings over a lifetime. 

By presenting this evidence, your attorney can demonstrate that the settlement offer must account for not only your immediate needs but also the long-term consequences of your injury. 

Protecting Your Right to Full Compensation 

California law allows TBI victims to recover both economic and non-economic damages. Economic damages cover medical costs, rehabilitation, lost wages, and future care. Non-economic damages address pain, suffering, loss of enjoyment of life, and emotional distress. 

Because brain injuries often evolve over time, it’s crucial to work with an attorney who understands the medical, legal, and financial aspects of TBI cases. The lawyers at Kalfayan Merjanian, LLP, investigate every detail of your injury, consult with leading medical experts, and calculate the full extent of your damages before entering settlement negotiations.

Why Proving a TBI Can Be Difficult

One of the main challenges in traumatic brain injury cases is that many TBIs do not show up on standard diagnostic tests. A concussion or mild TBI, for instance, may not appear on a CT scan or MRI, even though the victim experiences dizziness, headaches, memory problems, or mood changes. Insurance companies often seize on this gap in objective imaging to argue that the victim is exaggerating or that their symptoms stem from something other than the accident.

Because of this, proving a TBI usually requires combining multiple forms of evidence to establish that the injury exists, that it was caused by the accident, and that it has lasting consequences.

The Role of Medical Records

Medical records are the foundation of any TBI case. From the first emergency room visit to ongoing neurological evaluations, each note and diagnostic entry helps establish the timeline of symptoms and treatment. Doctors’ observations about confusion, disorientation, or loss of consciousness at the scene of an accident can carry significant weight in court. Follow-up visits with neurologists, neuropsychologists, or rehabilitation specialists also help to confirm that the symptoms are consistent with a brain injury.

Importantly, gaps in treatment or delays in seeking medical care can weaken a case, as insurers may argue the injury was not serious or was unrelated to the accident. This is why accident victims are advised to seek medical attention immediately, even if they don’t yet fully appreciate the nature of their symptoms.

Imaging and Diagnostic Tools

While TBIs may not always show up on traditional imaging, advanced scans such as diffusion tensor imaging (DTI) or functional MRI can reveal microstructural brain damage that standard tests miss. These advanced tools, though not always widely available, can provide powerful evidence in litigation.

In addition to imaging, neurocognitive testing is often used to assess the impact of a TBI. These tests evaluate memory, attention span, problem-solving skills, and processing speed—functions that are often impaired after a brain injury. A well-documented decline from the victim’s baseline abilities can serve as strong evidence.

Expert Testimony

Expert witnesses often play a central role in TBI cases. Neurologists, neuropsychologists, and rehabilitation specialists can testify about the extent of the injury and its impact on daily life. They may explain to the jury why an injury is real even if standard imaging looks “normal,” helping to counter common defense arguments.

Vocational experts may also be brought in to explain how the injury affects the victim’s ability to work, while life care planners can outline the long-term costs of treatment, therapy, and accommodations. In California personal injury cases, expert testimony often makes the difference between a claim that gets dismissed and one that results in full and fair compensation.

Linking the Injury to the Accident

Another critical element is causation, i.e., proving that the TBI was caused by the accident in question and not by another factor. Defense attorneys may point to prior head injuries, pre-existing conditions, or unrelated medical issues as alternative explanations for the symptoms. Overcoming these arguments requires detailed medical history reviews and, in some cases, testimony from treating physicians who can draw a direct connection between the accident and the TBI.

Demonstrating the Impact on Daily Life

Finally, a successful TBI case must show how the injury has changed the victim’s life. Testimony from family members, friends, and coworkers can be invaluable in painting a clear picture for the jury. They may describe changes in personality, memory problems, or the victim’s struggles with basic tasks. This type of evidence helps humanize the case and demonstrates the full scope of damages, both economic and non-economic, that the victim has suffered.

Compensation in California TBI Cases

If proven, a traumatic brain injury can lead to substantial compensation in a California personal injury lawsuit. Victims may recover economic damages, such as medical bills, lost income, and the cost of long-term care, as well as non-economic damages for pain, suffering, and diminished quality of life. In severe cases, where a TBI results in permanent disability, compensation must account for lifelong support and medical needs.

Contact Kalfayan Merjanian, LLP

Proving a traumatic brain injury in a personal injury lawsuit is a complex undertaking that requires medical expertise, legal strategy, and a strong commitment to telling the victim’s story. In cases where juries may not fully understand the invisible but life-changing nature of TBIs, success depends on building a compelling case grounded in evidence and expert testimony.

If you or a loved one has suffered a brain injury in an accident caused by another party’s negligence, consulting an experienced California personal injury attorney is the first step toward protecting your rights and securing the compensation you need for recovery.

1. Claiming the Injury Was Not Serious

One of the first strategies insurers often use in TBI claims is to downplay the injury. This is especially true in cases involving mild traumatic brain injuries (mTBIs) or concussions, which might not appear on standard CT scans or MRIs. Insurance adjusters may argue that because no visible damage shows up on imaging, the claimant is exaggerating symptoms.

How to Fight Back

• Medical documentation is key. Detailed records from neurologists, neuropsychologists, and rehabilitation specialists provide objective evidence of injury.
• Neurocognitive testing can demonstrate memory, attention, or problem-solving deficits, even when scans appear normal.
• Ongoing treatment records show that the injury has real, measurable impacts on daily life.

2. Arguing Pre-Existing Conditions Were the Cause

Insurers may claim that your TBI symptoms existed before the accident or are the result of prior injuries or conditions. This defense seeks to shift blame away from the liable party and onto the victim.

How to Fight Back

• Provide thorough medical history documentation to show your baseline before the accident.
• Obtain expert testimony linking the current symptoms directly to the traumatic event.
• Highlight timeline evidence: emergency room notes, first reports of symptoms, and early medical evaluations establish causation.

3. Suggesting the Victim Was at Fault

Insurance companies may try to invoke comparative negligence, arguing that the victim’s own actions contributed to the accident. For instance, they might claim the injured person was not paying attention, failed to wear a seatbelt, or engaged in risky behavior.

How to Fight Back

• California follows a pure comparative negligence system, meaning damages are reduced only by the percentage of fault assigned.
• A skilled attorney can gather evidence, such as witness statements, surveillance footage, and expert reconstruction, to show that the insured party’s negligence was the primary cause.
• Highlighting the dangerous conditions or actions of the other party can help minimize any assigned fault.

4. Denying Long-Term Effects or Future Damages

TBIs can have long-term consequences, including cognitive impairment, emotional changes, and difficulty returning to work. Insurance companies often argue that future damages are speculative and should not be compensated.

How to Fight Back

• Use life care plans and vocational experts to document the expected long-term medical, therapeutic, and occupational needs.
• Present testimony from rehabilitation specialists and neuropsychologists explaining why future care and accommodations are reasonably necessary.
• Include personal testimony and daily life documentation to show how the TBI has affected your ability to function, work, and engage in relationships.

5. Claiming Treatment Was Inadequate

Another tactic is to argue that the claimant did not seek treatment promptly, failed to follow medical advice, or missed appointments, suggesting that the injury is either exaggerated or worsened by the victim’s actions.

How to Fight Back

• Seek immediate medical attention after the accident and maintain all treatment records.
• Document any reasons for delays, such as difficulty finding specialists, mobility limitations, or initial misdiagnosis.
• Maintain a consistent record of ongoing care, including therapy, medications, and check-ups, to demonstrate responsible management of the injury.

6. Questioning the Credibility of the Victim

Insurance adjusters may attempt to paint the claimant as unreliable, exaggerating symptoms, or untruthful about the accident and its effects.

How to Fight Back

• Keep a daily log of symptoms, limitations, and treatments to provide a clear timeline.
• Gather witness statements from family, friends, and coworkers to corroborate changes in behavior, mood, or abilities.
• Consistency in your statements to medical providers, attorneys, and insurers strengthens credibility.

The Importance of Experienced Legal Representation

Dealing effectively with the defenses put up by insurance companies in TBI cases is complex. Insurance carriers have teams trained to minimize payouts and exploit legal loopholes, but victims do not have to face them alone. An experienced California personal injury attorney can:

• Gather and organize medical evidence and expert testimony.
• Handle communications with insurers to prevent misleading statements from being used against you.
• Anticipate common defenses and develop strategies to counter them effectively.
• Ensure all damages—both economic and non-economic—are fully documented and presented.

Contact the California Trial Attorneys at Kalfayan Merjanian Today

Below we discuss what mTBI is, the circumstances under which you may sue, the types of damages available, and the challenges of proving your case. Contact Kalfayan Merjanian, LLP, to consult with a California personal injury lawyer experienced in TBI and other catastrophic injuries caused by another’s negligence or wrongful conduct.

Understanding Concussions and Mild TBIs

A concussion is the most common type of traumatic brain injury. It typically results from a blow to the head, a fall, or a sudden jolt that causes the brain to move inside the skull. Car accidents, slip and fall incidents, workplace accidents, and sports injuries are among the most frequent causes.

While many people recover fully from a concussion, others experience prolonged symptoms such as headaches, memory problems, sensitivity to light and sound, balance issues, mood swings, and difficulty concentrating. In some cases, post-concussion syndrome can last for months or years, creating long-term difficulties.

When a Concussion Becomes Grounds for a Lawsuit

Not every concussion leads to a lawsuit. To pursue legal action, the injury must have been caused by another party’s negligence or wrongful conduct. Common situations include:

• Car Accidents – If another driver’s careless or reckless behavior caused the collision that led to your concussion, you may have a valid claim.
• Slip and Fall Accidents – Property owners who fail to maintain safe premises may be liable if a hazardous condition caused your fall.
• Workplace Accidents – Employees injured on the job may be eligible for workers’ compensation, and in some cases, may pursue additional claims if a third party was responsible for the accident.
• Sports or Recreational Activities – Schools, leagues, or organizations may be held accountable if negligence in supervision, equipment, or safety protocols led to the injury.
• Assaults – Victims of intentional harm may pursue civil damages in addition to any criminal proceedings against the perpetrator. The owner of the premises where the assault occurred is sometimes liable if their negligent security enabled or facilitated the assault.

The central legal question is whether another party’s negligence or intentional act directly caused your injury.

The Role of Negligence in mTBI Lawsuits

Except in cases of intentional misconduct, to succeed in a personal injury lawsuit, you must establish the elements of a negligence claim:

1. Duty of Care – The defendant owed you a legal duty (for example, drivers must operate vehicles safely; property owners must maintain safe premises).
2. Breach of Duty – The defendant failed to meet that duty through careless or reckless negligent behavior.
3. Causation – The breach directly caused your concussion or mTBI.
4. Damages – You suffered measurable harm, such as medical expenses, lost wages, or pain and suffering.

Because concussions are sometimes harder to detect than more obvious injuries, proving the connection between the negligent act and your ongoing symptoms often requires strong medical evidence.

Proving a Concussion or mTBI in Court

One of the challenges in mTBI cases is that imaging scans like MRIs or CT scans often appear normal, even when the injured person is experiencing significant symptoms. This makes medical documentation and expert testimony especially important. Evidence may include, for example:

• Emergency room and hospital records from the time of the accident
• Neurological evaluations documenting cognitive or memory problems
• Neuropsychological testing that highlights deficits in concentration, reaction time, or executive functioning
• Testimony from treating physicians linking the injury to the accident
• Statements from family, friends, or co-workers describing changes in your behavior, mood, or ability to function

An experienced attorney can coordinate with medical experts to present the strongest possible case.

Damages Available in mTBI Lawsuits

If successful, a lawsuit for a concussion or mTBI may provide compensation for both economic and non-economic damages, such as:

• Medical expenses (past and future)
• Lost income and reduced earning capacity
• Rehabilitation and therapy costs
• Pain and suffering
• Loss of enjoyment of life
• Emotional distress

In rare cases involving gross negligence or intentional harm, punitive damages may also be awarded.

The Statute of Limitations

The time you have to file a lawsuit after a concussion varies by state. In California, the statute of limitations for most personal injury cases is two years from the date of the injury. Missing this deadline could prevent you from recovering compensation, even if you have a strong case. For minors or cases where the injury was not immediately discoverable, special rules may apply.

Why Legal Help Matters

Because concussions and mTBIs can be difficult to prove in court, and because insurance companies often downplay these injuries, working with a skilled personal injury attorney can be critical. An attorney can help gather medical evidence, consult with experts, calculate the full value of your damages, and negotiate aggressively with insurers.

How a Slip and Fall Can Cause a Traumatic Brain Injury

Slip and fall accidents occur when a person loses their footing due to a hazard such as a wet floor, loose carpet, uneven surface, poor lighting, or cluttered walkway. When the fall causes the head to strike the ground or another hard object on the way down, the force can jolt the brain within the skull. This impact can result in a range of brain injuries, from concussions to more serious trauma such as hemorrhages or diffuse axonal injuries.

Common types of TBIs from falls include:

• Concussions – Often caused by a direct blow to the head or a sudden jolt, concussions can lead to headaches, confusion, memory problems, and dizziness. Even mild concussions can have long-term effects if not properly treated.
• Contusions – A contusion is a bruise on the brain that occurs when the brain strikes the inside of the skull. This may require surgery if bleeding or swelling becomes severe.
• Intracranial Hemorrhages – Falls can cause bleeding in or around the brain, including subdural hematomas or epidural hematomas. These conditions are medical emergencies and may not show immediate symptoms.
• Diffuse Axonal Injury (DAI) – In more violent falls, especially those involving rotation or sudden deceleration, the brain’s long connecting fibers (axons) can stretch and tear, leading to widespread brain damage.

Elderly individuals are especially vulnerable to fall-related TBIs. As we age, balance issues, reduced strength, and slower reflexes make falls more likely and the consequences more severe. A head injury that a younger adult might recover from in weeks can prove life-threatening or permanently disabling for an older person. A negligent property owner can be liable for the damages to a fall victim regardless of their stage in life.

Where Do Slip and Fall TBIs Happen?

Slip and fall accidents that lead to traumatic brain injuries can occur almost anywhere, but some of the most common locations include:

• Retail stores and supermarkets, where spills, wet floors, or obstacles in aisles go unaddressed
• Restaurants and bars, where floors may be greasy or poorly lit
• Hotels and apartment buildings, where stairwells, walkways, and elevators may be inadequately maintained
• Construction sites, where falls from scaffolding, ladders, or platforms are an ever-present risk
• Sidewalks and parking lots, where cracked pavement, ice, or debris create hazards for pedestrians
• Nursing homes and assisted living facilities, where failure to supervise or assist residents can result in devastating falls

Who’s Liable for a Fall-Related Brain Injury in California?

California property owners and businesses have a legal duty to maintain reasonably safe premises. This duty may include inspecting the property for hazards, fixing known dangers, and warning visitors of unsafe conditions. When they fail to do so, and someone is injured as a result, they may be held liable under California premises liability law.

To bring a successful claim for a fall-related TBI, you must generally prove:

1. The property owner or manager knew or should have known about the dangerous condition.
2. They failed to repair the condition or failed to provide adequate warning.
3. This negligence directly caused the fall and the resulting injuries.

At Kalfayan Merjanian, LLP, our legal team conducts a thorough investigation to gather evidence such as surveillance footage, maintenance records, witness statements, and incident reports. We work with medical experts and economists to document the full impact of the brain injury, from emergency treatment and hospitalization to lost income and long-term care needs.

Long-Term Consequences of TBIs from Falls

Unlike a broken bone that can heal with time, a traumatic brain injury often results in permanent changes to a person’s physical, cognitive, and emotional abilities. Some fall victims may lose their ability to work or care for themselves. Others experience chronic headaches, difficulty speaking, memory problems, or mood disturbances such as anxiety and depression.

Many TBI victims also experience persistent dizziness and balance problems, which can make even simple tasks like walking, climbing stairs, or standing for long periods feel unsafe or disorienting. These issues often stem from damage to the parts of the brain that control spatial orientation and motor coordination. In some cases, vestibular therapy may help, but for others, the symptoms become chronic and severely impact independence and quality of life.

Severe TBIs may require extensive rehabilitation, in-home assistance, or even lifelong care in a skilled nursing facility. The financial burden on the injured person and their family can be overwhelming, especially if insurance coverage is inadequate or denied.

By pursuing a personal injury claim, victims may be able to recover compensation for matters such as:

• Medical expenses (past and future)
• Lost wages and diminished earning capacity
• Pain and suffering
• Loss of enjoyment of life
• Long-term care and rehabilitation costs

Loss of Consciousness

Even a brief loss of consciousness after an accident may indicate a concussion or more serious brain trauma. Some victims black out for just a few seconds and mistakenly assume they’re fine once they “come to.” But any loss of consciousness is a red flag that the brain has been impacted and needs to be evaluated by a medical professional.

Persistent or Worsening Headaches

Headaches are one of the most common symptoms following a head injury, but that doesn’t mean they should be taken lightly. A headache that doesn’t go away, becomes more intense, or worsens with time may be a sign of brain swelling, bleeding, or increased pressure inside the skull. These symptoms can escalate quickly and become life-threatening if not properly treated.

Nausea or Vomiting

Nausea or vomiting after an accident is often dismissed as a reaction to stress, but it’s also a hallmark sign of a brain injury, particularly when paired with a headache or dizziness. Repeated vomiting should be treated as an emergency and can signal a serious underlying problem, such as a hemorrhage or elevated intracranial pressure.

Dizziness or Balance Issues

Feeling lightheaded or unsteady on your feet after an accident can indicate damage to areas of the brain responsible for balance and coordination. This symptom may arise immediately or develop later, and it often affects a victim’s ability to return to work, drive, or perform daily tasks.

Blurred Vision or Sensitivity to Light

Visual problems such as blurry vision, double vision, or increased sensitivity to light are common with TBIs. These symptoms may point to injury in the brain’s occipital lobe or disruptions in how the brain processes visual information. Some victims also experience trouble with eye movement or focusing, which can interfere with reading or screen use.

Fatigue and Sleep Disturbances

Traumatic brain injuries often disrupt normal sleep patterns. Victims may sleep more than usual, have trouble falling asleep, or feel exhausted despite getting adequate rest. Fatigue can persist for weeks or months after a TBI and is frequently accompanied by cognitive fog or emotional changes.

Confusion, Memory Loss, or Difficulty Concentrating

Cognitive symptoms are often among the most disabling aspects of a TBI. Victims may forget appointments, struggle to find the right words, or have difficulty focusing on tasks. These issues are not just frustrating; they are clear indications that the brain’s ability to process, store, and retrieve information has been compromised.

Mood Swings, Irritability, or Depression

After a TBI, it’s common for victims to experience emotional changes that feel out of character. Irritability, mood swings, anxiety, depression, and even sudden outbursts can all result from damage to the brain’s emotional regulation centers. Unfortunately, these symptoms are often misunderstood or minimized, even though they have a profound effect on a person’s quality of life.

Ringing in the Ears (Tinnitus)

Ringing, buzzing, or hissing sounds in the ears may occur after a brain injury or a blow to the head. Tinnitus can be constant or intermittent and may contribute to anxiety, sleep issues, and concentration difficulties.

Seizures

Seizures can occur soon after a TBI or emerge days or weeks later. Even a single seizure should be taken seriously and evaluated as a possible sign of brain trauma. Post-traumatic epilepsy is a known risk after moderate to severe TBIs.

When to Seek Medical Help—and Legal Help

If you experience any of these symptoms after an accident, do not wait to seek medical evaluation. Some TBIs can be managed with rest and monitoring, while others require urgent medical intervention to prevent permanent brain damage. Early diagnosis is also essential for your legal case. Medical records and diagnostic imaging provide critical evidence linking your symptoms to the accident and the negligence of the party responsible.

At Kalfayan Merjanian, LLP, we understand how challenging it can be to navigate life after a brain injury.

What Is a Diffuse Axonal Injury?

A diffuse axonal injury occurs when the brain is subjected to rapid acceleration or deceleration—typically during a violent impact or rotation of the head. These forces cause the brain to move within the skull, stretching and tearing the long connecting nerve fibers known as axons.

This tearing disrupts communication between different areas of the brain and can lead to loss of consciousness, coma, or long-term cognitive impairment. Unlike a localized brain injury, which is confined to a specific area, a DAI affects multiple areas of the brain, particularly the white matter. This makes the condition both more serious and more complex.

Common causes of diffuse axonal injuries include:

• High-speed motor vehicle accidents (car, truck, motorcycle)
• Pedestrian or bicycle collisions
• Falls from heights
• Sports-related trauma
• Violent assaults or shaken baby syndrome

Depending on the severity, a DAI can result in a variety of symptoms, including confusion, memory loss, personality changes, problems with speech or movement, and persistent vegetative states.

Why Are Diffuse Axonal Injuries So Hard to Diagnose?

One of the most frustrating aspects of a diffuse axonal injury is that traditional imaging tools often fail to detect it. CT scans, commonly used in emergency rooms, may appear normal even when a serious injury has occurred. This is because DAIs typically involve microscopic damage that isn’t visible on standard imaging.

Diagnosis usually relies on:

• MRI scans, particularly advanced techniques like diffusion tensor imaging (DTI), which can reveal white matter abnormalities and axonal disruption.
• Neurological assessments by specialists to evaluate changes in cognition, motor skills, and behavior.
• Long-term observation of symptoms and functional impairments, often by a team of doctors, neuropsychologists, and rehabilitation therapists.

Due to the complexity and subtlety of the injury, DAIs are sometimes misdiagnosed—or dismissed entirely—as post-concussion syndrome or psychological distress. That’s why having skilled medical and legal professionals involved early is crucial.

Proving a Diffuse Axonal Injury in Court

Proving a DAI in court requires more than just a diagnosis—it requires a comprehensive legal and medical strategy to connect the injury to the incident and demonstrate the extent of its impact on the victim’s life. At Kalfayan Merjanian, LLP, we draw on a network of experts to build compelling cases on behalf of TBI victims.

Here are some key components to proving a DAI in court:

1. Expert Medical Testimony

Because DAIs often lack obvious visual confirmation on imaging, expert testimony is essential. Neurologists, neuropsychologists, and radiologists with experience in brain trauma can help explain how the injury occurred, why it may not show up on a CT scan, and what the long-term consequences are. Testimony may include interpretation of MRIs, cognitive testing, and explanations of the medical literature on DAI.

2. Advanced Neuroimaging

In some cases, advanced MRI techniques such as DTI or functional MRI (fMRI) can provide critical evidence. These scans can highlight changes in white matter integrity and provide objective proof of axonal damage. This type of evidence can be persuasive to both judges and juries, especially when supported by medical experts.

3. Neuropsychological Evaluation

A comprehensive neuropsychological exam can demonstrate how the injury has impaired a person’s ability to think, remember, focus, or interact with others. This is often the most practical way to measure the real-world impact of the injury and can help quantify damages for pain and suffering, lost earning capacity, and future care needs.

4. Testimony from Family and Friends

Lay witness testimony from people close to the victim can also be powerful. Spouses, siblings, co-workers, and friends can describe the changes they’ve seen in the victim’s personality, mood, memory, and behavior—helping to paint a complete picture of how the injury has affected everyday life.

5. Life Care Planning and Economic Analysis

For severe cases, proving damages may also involve input from a life care planner and an economic expert who can estimate the costs of future medical treatment, long-term care, vocational rehabilitation, and lost lifetime earnings. These projections are critical in obtaining full compensation for TBI victims and their families.

Car Accidents

Car accidents are one of the leading causes of traumatic brain injuries. Even at low speeds, the force of a collision can cause the brain to jostle inside the skull, leading to concussions, contusions, or more severe brain trauma. In high-speed crashes or rollovers, occupants are at risk of striking their heads against the steering wheel, dashboard, windows, or other hard surfaces. Airbags, while helpful in reducing overall injury, can also cause head trauma during deployment. Often, these accidents are caused by another driver’s distracted driving, speeding, or driving under the influence—forms of negligence that can make the at-fault driver liable for damages.

Truck Accidents

Truck accidents tend to cause more severe injuries than car crashes simply because of the size and weight disparity between passenger vehicles and commercial trucks. When a big rig collides with a smaller vehicle, the impact can be catastrophic. Victims are often thrown violently within the vehicle or struck by crushed roofs and doors, leading to blunt force trauma or penetrating head injuries. Truck accidents can be caused by unsecured cargo, driver fatigue, failure to follow safety regulations, or improper vehicle maintenance—all of which may involve multiple liable parties, from the driver to the trucking company.

Motorcycle Accidents

Motorcyclists are uniquely vulnerable to traumatic brain injuries due to their exposure and lack of physical protection. Although helmets significantly reduce the risk of fatal head injury, they cannot eliminate the possibility of a TBI, especially in high-speed crashes or collisions with larger vehicles. Riders thrown from their bikes may strike their heads on pavement, curbs, or guardrails. In California, where lane-splitting is legal, sudden moves by other drivers who fail to check blind spots or use turn signals can lead to devastating accidents on the highway, while negligent left turns at intersections on city streets remain a leading cause of serious or deadly motorcycle crashes.

Bus Accidents

Bus passengers often ride without seatbelts and may be standing when a collision occurs, putting them at risk of being tossed around the interior of the vehicle. Whether the victim is a bus passenger, pedestrian, or the occupant of another vehicle involved in a bus crash, the potential for a traumatic brain injury is significant. Causes of bus accidents include driver negligence, poor training, improper maintenance, and even defective equipment. Municipalities and private bus companies may bear responsibility depending on the circumstances of the crash.

Pedestrian Accidents

Pedestrians struck by vehicles often suffer severe, life-threatening injuries. With no protection from the force of impact, the head is particularly vulnerable. A pedestrian may hit the hood of a vehicle and then be thrown to the ground, sustaining multiple impacts that increase the likelihood of a traumatic brain injury. Many of these accidents happen at crosswalks or intersections where pedestrians have the right-of-way, often due to distracted driving, failure to yield, or speeding. California law offers strong protections for pedestrians, but those laws are of little comfort when someone is seriously hurt due to a driver’s negligence.

Bicycle Accidents

Like pedestrians and motorcyclists, bicyclists lack the protection of an enclosed vehicle, making them more susceptible to serious injuries in the event of a crash. Even with a helmet, the force of a collision with a car or the pavement can result in a TBI. Common causes of bicycle accidents include drivers failing to check for cyclists when turning or opening car doors, drifting into bike lanes, or speeding through residential neighborhoods. These accidents often occur in urban areas with heavy traffic or inadequate bike lane infrastructure.

ATV Accidents

All-terrain vehicles (ATVs) are popular for recreation but carry significant risk, especially when operated without proper safety measures. Riders may be thrown off an ATV during a rollover or collision, often landing on their heads. Helmets help, but the risk of brain injury remains high, particularly if the ATV is used on unstable terrain or by inexperienced riders. In some cases, design or manufacturing defects may contribute to an accident, opening the door to a product liability claim. Landowners may also bear responsibility if they failed to warn of hidden dangers on their property.

Slip and Fall Accidents

While not typically as dramatic as vehicle collisions, slip and fall accidents can also cause traumatic brain injuries. A sudden fall on a hard surface can cause a person to hit their head with significant force, leading to concussions or more serious forms of TBI such as brain hemorrhages. Falls are especially dangerous for older adults, who may suffer long-term cognitive decline after a head injury. Slip and fall accidents often occur due to wet floors, broken handrails, uneven pavement, poor lighting, or other hazards that property owners are legally obligated to address in a timely fashion.
