Traumatic brain injury claims are among the most misunderstood cases in California injury law. A person can walk away from a crash, have an initial CT scan that shows no obvious abnormality, and still experience symptoms that affect memory, concentration, work, sleep, and daily life. This disconnect between early diagnostic findings and later symptoms can make these claims particularly dependent on medical records and evidence showing how the injury affects the person over time.
That evidentiary challenge is one reason serious brain injury cases often require more than proof of the collision itself. Medical evaluations, treatment records, testimony about behavioral or cognitive changes, employment records, and evidence of future limitations may all become relevant when documenting the extent of an injury. MVP Accident Attorneys handles catastrophic injury cases involving these issues, giving its traumatic brain injury lawyer practice a direct connection to disputes over how brain injuries are diagnosed, documented, and valued after California crashes.
Below are seven common myths surrounding traumatic brain injury claims and the facts that help clarify them.
Myth 1: “If I Didn’t Hit My Head, I Can’t Have a Brain Injury.”
Fact: A brain injury can happen without any blow to the head.
The brain moves inside the skull. A sudden stop or impact, like a rear-end or side-impact crash, can make the brain shift and strike the inside of the skull. That movement can stretch and damage nerve fibers even when nothing touches the head.
The Centers for Disease Control and Prevention defines traumatic brain injury to include injuries caused by a bump, blow, or jolt to the head. A jolt is enough.
Myth 2: “My CT Scan Was Normal, So I’m Fine.”
Fact: A normal CT scan does not rule out a brain injury.
Emergency room CT scans look for bleeding, swelling, and skull fractures, which need urgent treatment. Many mild traumatic brain injuries, including concussions, do not show up on a CT scan at all.
When symptoms continue, doctors may use other tools:
- Neurological exams
- Neuropsychological testing of memory, attention, and processing speed
- MRI, including advanced techniques that can show subtle damage
- Vision, balance, and hearing tests
A normal scan in the emergency room is often the starting point of a brain injury claim, not the end of it.
Myth 3: “A Mild TBI Isn’t a Serious Claim.”
Fact: “Mild” describes the initial severity, not the long-term impact.
Doctors often classify brain injuries as mild, moderate, or severe based on early signs, such as a person’s Glasgow Coma Scale score or how long they lost consciousness. Many people with mild injuries recover within weeks. Others have symptoms for months or longer, including:
- Headaches and sensitivity to light or noise
- Trouble concentrating or remembering
- Fatigue and sleep problems
- Irritability, anxiety, or depression
- Dizziness and balance problems
If those symptoms affect work or daily life, the claim can be significant.
Myth 4: “Symptoms Would Show Up Right Away.”
Fact: Brain injury symptoms can appear or worsen over hours or days.
Adrenaline at the scene can mask symptoms. Problems with memory or focus may only become clear when a person returns to work or school. This delay is common, and insurers sometimes use it to argue the crash did not cause the injury.
That is why getting checked soon after a crash, and reporting new symptoms promptly, matters both for health and for the record.
Myth 5: “California Caps Pain and Suffering in Car Accident Cases.”
Fact: California does not cap non-economic damages in ordinary vehicle crash cases.
California’s well-known damage limits under MICRA apply to medical malpractice claims, not to car or truck crashes. In a brain injury case caused by a negligent driver, a jury can award damages for pain, emotional distress, and loss of enjoyment of life without a statutory cap.
Other rules still apply:
- Medical bills are generally limited to amounts actually paid or owed, under Howell v. Hamilton Meats (2011).
- Comparative fault: California reduces damages by the injured person’s share of fault but does not bar recovery.
- Uninsured drivers: Under Proposition 213, a driver who was uninsured at the time of the crash generally cannot recover non-economic damages from the at-fault driver.
Myth 6: “I Should Settle Quickly Before My Bills Pile Up.”
Fact: Settling too early can leave future care unpaid.
Once you sign a release, the claim is generally over, even if symptoms get worse. Brain injury claims often need time to answer key questions:
- Will symptoms improve, plateau, or worsen?
- Will the person return to the same job?
- Will they need therapy, medication, or support for years?
In serious cases, a life care planner and an economist may estimate future medical costs and lost earning capacity. Those numbers often exceed the bills already received.
Myth 7: “I Have Plenty of Time to Decide.”
Fact: California deadlines are shorter than many people expect.
Under California Code of Civil Procedure Section 335.1, most personal injury lawsuits must be filed within two years. Claims involving a government vehicle or public road generally require a written claim within six months. For injured children, the deadline is usually paused until they turn 18.
Brain injury cases also depend on evidence that fades, such as early medical notes and witness memories of how the person acted right after the crash.
What Evidence Builds a Strong TBI Claim?
The strongest brain injury claims combine medical and everyday evidence:
- Emergency room and follow-up medical records
- Neurology and neuropsychology evaluations
- Imaging results, including any MRI studies
- Statements from family, friends, and coworkers about changes in behavior
- Employment records showing missed work or reduced performance
- A symptom journal kept by the injured person or family
The “before and after” picture from people who know the injured person is often what makes an invisible injury visible to an insurer or jury.
- A brain injury can occur without hitting the head.
- A normal CT scan does not rule out a traumatic brain injury.
- “Mild” TBI can still cause long-lasting symptoms that support a significant claim.
- California does not cap pain and suffering in vehicle crash cases.
- Most California injury lawsuits must be filed within two years, and government claims within six months.
Traumatic brain injury claims are won by replacing assumptions with evidence. The sooner the medical and personal record is built, the harder it is for anyone to dismiss the injury.
