You were checked out at the scene and told you were fine. Now, days or weeks later, you’re forgetting things, your headaches won’t go away, or you’re not quite yourself. This is common after a car accident, and it is one of the main reasons people wait too long to talk to a TBI lawyer. This post explains what a brain injury can look like, how doctors diagnose it, and what your legal options are once you know what you’re dealing with, including when it’s time to bring in a TBI lawyer.
What Counts as a Traumatic Brain Injury After a Car Accident
A traumatic brain injury happens when a sudden jolt, blow, or impact disrupts normal brain function. You do not need to hit your head directly. The whiplash motion of a crash can be enough to cause the brain to move inside the skull. Doctors generally classify TBIs as mild, moderate, or severe, and even a “mild” injury (often called a concussion) can carry real, lasting effects. This range is exactly why so many people never think to call a TBI lawyer. They assume a normal-looking scan or a clean release from the ER means nothing serious happened, when a brain injury attorney will tell you the opposite is often true.
Symptoms to Watch For, Including the Ones That Show Up Later
Some signs of a brain injury appear right away: confusion, dizziness, a brief loss of consciousness, or a headache that starts at the scene. But TBIs are unusual among injuries because a meaningful share of symptoms take days or even weeks to surface. Watch for:
- Headaches that develop or worsen days after the crash
- Trouble concentrating, remembering things, or finishing simple tasks
- Sensitivity to light or noise that wasn’t there before
- Sleep that’s suddenly disrupted, whether you’re sleeping far more or far less
- Irritability, anxiety, or mood changes that feel out of character
- Ringing in the ears or a change in taste or smell
- Dizziness or balance problems that come and go
If you’re reading this as a spouse, parent, or friend rather than the injured person, that matters too. Family members are often the first to notice these changes, since the person going through them may not recognize the shift themselves. Any of these symptoms, appearing at any point after a crash, is a reason to see a doctor, not a reason to wait and see. It’s also a reason to keep a TBI lawyer’s number handy, even before you know how serious things are.
How Doctors Diagnose a TBI
Diagnosis usually starts with a neurological exam, checking things like reflexes, coordination, and memory. From there, doctors may order:
- A CT scan, typically the first imaging test after a head injury, to check for bleeding or swelling
- An MRI, which can pick up on more subtle injury than a CT scan
- A neuropsychological evaluation, which measures memory, attention, and processing speed over time
Here is the part that matters for both your health and your claim: a normal CT scan does not rule out a brain injury. Many concussions and mild TBIs never show up on standard imaging, which is exactly why insurers lean on a clean scan to argue nothing happened. According to the Centers for Disease Control and Prevention, motor vehicle crashes are among the leading causes of TBI-related hospitalization in the United States, and symptoms can appear or worsen well after the initial exam. Follow-up care and a documented symptom timeline are often what actually prove the injury, which is a large part of what a TBI lawyer helps you build.
What the Insurance Company Does Here
Brain injuries are exactly the kind of claim adjusters are trained to minimize, because the evidence is not always visible on a scan. Expect the adjuster to point to a normal CT scan or a fast ER discharge as proof you’re fine, downplay memory or mood symptoms as unrelated to the crash, and push for a quick settlement before your full symptom picture has developed. Many adjusters also ask for a recorded statement early, before your symptoms have had time to surface, and you are not required to give one. None of this means your injury isn’t real. It means the burden falls on you to document it. Eli Rezvani’s background in insurance defense means our firm has seen this pattern from the inside, and a TBI lawyer’s job at this stage is largely about closing the gap between what the medical record shows and what you’re actually experiencing.
What to Do If You Suspect a TBI
- See a doctor as soon as new or worsening symptoms appear, even weeks after the crash.
- Keep a simple daily log of symptoms, so a pattern that isn’t obvious in a single visit becomes clear over time.
- Follow through on referrals, including neurology, neuropsychology, or physical therapy.
- Avoid activities that risk a second head injury while you’re recovering.
- Do not accept a settlement offer before your treatment and prognosis are better understood.
- Talk to a TBI lawyer early, so the right records are being gathered from the start. A head injury lawyer who understands how these claims are built can also help you avoid mistakes that are hard to undo later.
FAQ
How soon after a crash can TBI symptoms appear? Immediately in some cases, and days to weeks later in others. According to the Mayo Clinic, some signs and symptoms of a traumatic brain injury may not appear until days or weeks after the injury, which is part of why ongoing symptom tracking matters.
Do I need a TBI lawyer if my scan came back normal? Often, yes. A normal CT or MRI does not rule out a brain injury, and insurers frequently use a clean scan to argue there’s nothing to compensate. A TBI lawyer can help connect your symptoms and follow-up care to the crash, which is often the deciding factor in these claims.
What does a brain injury attorney actually do in these cases? Beyond handling the claim, a TBI lawyer typically works with your treating doctors, and sometimes independent medical experts, to document how the injury affects your daily life, your work, and your future care needs.
Is there a deadline to bring a TBI claim in California? California generally allows two years from the date of injury to file a personal injury lawsuit under Code of Civil Procedure section 335.1, but the deadline can be shorter in certain situations, including claims against a government agency. Your specific deadline depends on the facts of your case, which is another reason to talk to a TBI lawyer sooner rather than later.
What if the driver who caused my crash didn’t have insurance? A TBI claim can still move forward. If the other driver was uninsured or underinsured, your own policy’s coverage may apply instead, though the process works a little differently than a standard claim.
What if the person with the TBI can’t manage the claim themselves? This is common with more significant brain injuries. A family member, often acting under a power of attorney or as a guardian, can usually step in to handle communication with the lawyer and the insurer.
