California brain injury attorneys handle claims where a head injury changes how someone thinks, works, or functions. These cases turn on proving an injury that often does not appear on a standard scan. Most must be filed within two years, and value depends on documented limits, not bills alone.
B&D Injury Law Group represents people with traumatic brain injuries across California. This page covers how these injuries are classified, what causes them, why symptoms get missed at the emergency room, what you must prove, and how claims are valued.
When Should You Contact California Brain Injury Attorneys?
Contact California brain injury attorneys as soon as a doctor mentions concussion, head trauma, or post-concussive symptoms. Early involvement matters because the proof comes from neuropsychological testing, consistent symptom reporting, and witness accounts of how you changed, all strongest when gathered early.
You do not need a diagnosis of severe brain damage to have a real claim. Many hard-fought cases involve people released from the emergency room the same day who then could not return to their job.
What Counts as a Traumatic Brain Injury?
A traumatic brain injury is damage to brain function caused by an outside force: a blow to the head, a violent jolt, or an object penetrating the skull. Clinicians classify severity by level of consciousness, memory loss around the event, and imaging findings. A concussion is a mild traumatic brain injury.
The word “mild” describes how the injury presented at the hospital, not how it affects your life. People with mild traumatic brain injuries commonly report headaches, light sensitivity, word-finding trouble, irritability, and trouble holding attention through a full workday.
| Severity Classification | How It Usually Presents | Common Effect on a Claim |
|---|---|---|
| Mild (including concussion) | Brief or no loss of consciousness, normal CT scan | Most disputed; requires neuropsychological proof |
| Moderate | Longer unconsciousness or confusion, findings on imaging | Liability fight shifts to future care needs |
| Severe | Extended unconsciousness, bleeding or swelling in the brain | Life care planning and earning capacity drive value |
What Causes Brain Injuries in California Injury Cases?
The most common causes we see are vehicle collisions, falls on unsafe property, bicycle and pedestrian crashes, motorcycle collisions, construction site accidents, and being struck by falling objects. Assaults on poorly secured property and recreational incidents also produce head trauma leading to claims.
Vehicle cases often involve no direct head strike. Rapid acceleration and deceleration can injure the brain inside the skull even when no airbag deployed.
Why Are Brain Injury Symptoms Missed at the Emergency Room?
Emergency departments screen for injuries needing immediate intervention, such as bleeding or swelling. A standard CT scan can look normal while the injury still affects memory, attention, mood, and processing speed. Those effects usually become obvious later, when you try to return to work or school.
The answer is documentation. Neuropsychological testing measures cognitive function against expected baselines, treating neurologists record symptom patterns, and statements from a spouse, supervisor, or teacher about what changed often carry weight with a jury.
What Do You Have to Prove in a California Brain Injury Case?
You must prove that someone owed you a duty of care, failed to meet it, caused your injury, and that the injury caused specific losses. Causation is usually the battleground, because the defense argues the symptoms come from stress, aging, depression, or a prior condition.
California follows pure comparative negligence. If you are partly at fault, your recovery is reduced by that percentage rather than eliminated, and no cutoff percentage bars recovery.
How Long Do You Have to File a Brain Injury Claim in California?
Most California injury lawsuits must be filed within two years of the injury under Code of Civil Procedure section 335.1. If a government entity is involved, such as a public agency vehicle or a dangerous condition on public property, you must generally file an administrative claim within six months under Government Code section 911.2.
Different rules apply to injured minors and to claims arising from medical care, so the deadline should be confirmed early rather than assumed.
What Should You Do After a Head Injury?
Protect your health first, then protect the record. These claims turn on whether the symptoms were documented consistently from the beginning, so the goal in the first weeks is a clear medical file, a written account of what changed, and no unexplained gaps in care.
- Get evaluated the same day and report every symptom, including mood and sleep changes.
- Ask for a neurologist referral if headaches, memory problems, or dizziness continue.
- Keep a short daily journal noting what you could not do that day.
- Have a family member note changes in your behavior or personality.
- Save work records showing missed days, reduced hours, or accommodations needed.
- Follow treatment recommendations and avoid long gaps between appointments.
- Do not give a recorded statement or accept an early offer before a neurologist weighs in.
How Is a California Brain Injury Claim Valued?
Value depends on the severity of the cognitive and physical limitations, the care already provided, the care projected for the future, lost income and earning capacity, and how much insurance exists. No lawyer can quote a figure without reviewing the records and policy limits.
In serious cases, life care planners and economic experts translate the medical picture into projected costs, which separates a claim valued on past bills from one valued on a lifetime of need. Available coverage is often the practical ceiling, so identifying every policy is part of the early work.
Frequently Asked Questions
Can I have a brain injury if my CT scan was normal?
Yes. CT scans are designed to find bleeding, swelling, and fractures that need emergency treatment. They are not sensitive to the diffuse injury behind many lasting concussion symptoms. A normal scan does not rule out a traumatic brain injury, and neuropsychological testing often documents the real functional problems.
What if I had a prior head injury or a pre-existing condition?
A prior condition does not bar a claim. California law generally allows recovery for the aggravation of a pre-existing condition, so the party at fault is responsible for the added harm. Tell your attorney your full medical history, because a surprise record found by the defense damages credibility more than the history itself.
How long does a brain injury case take?
Longer than most injury claims. These cases are usually not valued until treating physicians can say whether the deficits are permanent, which can take a year or more of treatment and testing. Disputed causation or significant future care commonly requires a filed lawsuit, extending the timeline further.
Who pays for treatment while the case is pending?
Health insurance, med-pay coverage on an auto policy, or in some cases a provider willing to treat on a lien basis. Each option affects reimbursement out of a later settlement. Discuss the arrangement before treatment begins so repayment obligations are understood and can be negotiated later.
Do brain injury cases go to trial?
Most resolve through negotiation or mediation, but brain injury claims are contested more often than routine cases because causation is disputable. Preparing the case as if it will be tried, with credible experts and consistent documentation, is what generally produces a serious offer. You decide whether to accept one.
