Traumatic Brain Injury After a Car Accident: What San Diego Victims Need to Know

A traumatic brain injury is one of the most life-altering consequences of a car accident — and one of the most commonly underestimated. Victims may walk away from a crash feeling shaken but “okay,” only to notice problems days or weeks later: persistent headaches, difficulty concentrating, memory gaps, mood swings, and sensitivity to light or sound. If you suffered a TBI in an accident in San Diego or Chula Vista, De Santis Law Center fights to make sure the full extent of your injury — not just the visible damage — is reflected in your compensation. Our attorneys have 65+ combined years representing serious injury victims across San Diego County.

How Common Are Brain Injuries in Car Accidents?

Motor vehicle crashes are one of the leading causes of traumatic brain injuries in the United States. According to the Centers for Disease Control and Prevention (CDC), there were 68,663 TBI-related deaths in 2023 and approximately 214,110 TBI-related hospitalizations in 2020 — meaning nearly 586 people are hospitalized for brain injuries every single day. Vehicle crashes consistently rank among the top three causes of TBI alongside falls and assault.

The brain injury does not need to be severe to have lasting effects. Concussions — classified as mild TBIs — can cause weeks or months of symptoms that prevent people from working, driving, or caring for their families. Moderate and severe TBIs can result in permanent cognitive, emotional, and physical disabilities. Insurance companies routinely undervalue TBI claims, particularly for mild to moderate injuries where the damage is not visible on a standard CT scan.

Types of Brain Injuries That Occur in Car Accidents

The sudden deceleration of a crash causes the brain to move inside the skull — striking, rotating, and sometimes twisting against the cranial walls. The result can be a concussion (the mildest form, but still serious), a contusion (bruising of brain tissue), a diffuse axonal injury (DAI — caused by rotational forces that shear nerve fibers throughout the brain, often with no visible CT findings but severe cognitive effects), or an intracranial hemorrhage (bleeding inside the skull, which is a medical emergency).

One of the most insidious aspects of car accident TBIs is that they are not always immediately apparent. The brain is not like a broken arm — there is no obvious external sign. Symptoms appear gradually, and victims sometimes dismiss them as “just stress” or “whiplash.” If you were in a significant crash and are experiencing any cognitive, emotional, or neurological changes in the weeks that follow, see a doctor and call an attorney. Delay in diagnosis both endangers your health and weakens your legal claim.

Why Insurance Companies Fight TBI Claims

Insurance adjusters are trained to minimize TBI payouts — and they have specific strategies for doing so. They argue that symptoms are subjective and not verifiable. They point to a “normal” CT scan as evidence you weren’t seriously hurt (ignoring that mild and moderate TBIs often show no CT findings). They delay settlements hoping victims will accept less before the full extent of their impairment becomes clear. And they target gaps in medical treatment as evidence that the injury wasn’t serious.

The counter to these tactics is thorough medical documentation from the right specialists — neurologists, neuropsychologists, and occupational therapists — combined with legal representation that understands how to present TBI evidence persuasively. Our team works with San Diego’s top brain injury specialists to build the medical record that accurately captures what you’re going through — and what your future care will cost. Our case results include serious TBI cases where we recovered significantly more than the insurer’s initial offer.

Proving a TBI Claim: The Evidence You Need

A strong TBI claim requires layered evidence. Medical records documenting the diagnosis and your treatment course are foundational. Neuropsychological testing — which measures cognitive function across memory, attention, processing speed, and executive function — is often more probative than imaging for mild to moderate TBIs. Witness accounts from people who knew you before and after the accident (family, coworkers, friends) who can describe behavioral and cognitive changes are powerful. Employment records showing reduced performance or inability to work help establish economic damages.

We also work with life care planners who project future medical costs — ongoing therapy, medications, in-home assistance, and potential long-term care needs — so that your settlement or verdict reflects not just what you’ve already spent but what your injury will cost you for the rest of your life. Understanding the full value of a California personal injury case involving TBI requires this kind of thorough, forward-looking analysis.

Compensation Available for TBI Victims in San Diego

TBI victims can recover: all past and future medical expenses (including rehabilitation, therapy, and long-term care), lost wages and diminished earning capacity, pain and suffering, emotional distress, and loss of enjoyment of life. In cases involving severe TBI, these amounts can be substantial — running into millions of dollars when lifetime care needs are properly documented. Our Chula Vista attorneys fight to recover the full, accurate picture of what this injury has cost you and will continue to cost you.

Frequently Asked Questions About TBI Claims in California

The CT scan was normal but I still have symptoms — do I have a case?

Yes. A normal CT scan does not rule out a significant TBI. Diffuse axonal injuries and many concussions show no CT findings. MRI, especially diffusion tensor imaging (DTI), and neuropsychological testing are more sensitive and are the standard of care for diagnosing TBI beyond the emergency room. We work with neurologists who know how to properly document these injuries.

How long do TBI symptoms typically last?

Concussion symptoms typically resolve within days to a few months, though post-concussion syndrome can persist for a year or more. Moderate and severe TBIs can result in permanent impairments. Your prognosis matters enormously to the value of your case, which is why we retain medical experts to provide accurate long-term assessments.

What if I did not seek treatment right away?

A gap in treatment is a problem — but not an insurmountable one. We can often explain delayed diagnosis by documenting the gradual onset of symptoms that many TBI victims experience. The sooner you begin treatment now, the better both your health outcomes and your legal claim. Call us and we will help you understand what the gap means for your specific situation.

Can I still file a claim if the accident was partly my fault?

Yes. California’s comparative negligence rule allows you to recover damages proportional to the other party’s share of fault. Even if you were 25% at fault, you can recover 75% of your damages. A TBI is a serious injury — you deserve compensation regardless of partial fault.
