How Brain Injury Claims From Car Accidents Are Proven

Why brain injury claims face more resistance than most

Insurance companies often lean on a simple argument: the CT scan in the emergency room was normal, so the injury must be minor or must not exist. That argument is medically incomplete. Standard CT scans are designed to catch bleeding, skull fractures, and swelling, the injuries that need emergency intervention. Many traumatic brain injuries, especially concussions and other so-called mild TBIs, involve damage at a level those scans were never built to detect.

“Mild” is a medical classification, not a description of how the injury affects a life. A person with a mild TBI may struggle with memory, concentration, word-finding, mood, sleep, headaches, and sensitivity to light or noise for months or longer. The claim has to prove what the scan cannot show, and that takes a deliberate approach.

The record starts at the scene and in the emergency room

The earliest records often carry the most weight. When we review a brain injury case, we look for the foundation laid in the first hours and days:

• Crash records. Police reports, photos, and vehicle damage help establish the forces involved. A brain injury does not require a direct blow to the head; rapid acceleration and deceleration alone can injure the brain.
• Loss of consciousness or altered awareness. Notes from EMS or the emergency room about being dazed, confused, or unable to recall the crash are significant, even if consciousness was never fully lost.
• Early symptoms. Headache, dizziness, nausea, confusion, and memory gaps documented at the first visit connect the injury to the crash from day one.

This is one reason we encourage anyone in a serious crash to be evaluated promptly and to report every symptom, not just the ones that seem important. Symptoms you don’t mention early are the ones insurers later argue came from something else.

When imaging looks normal, testing fills the gap

If standard imaging is clear but symptoms persist, the medical workup usually deepens, and the claim deepens with it.

1. Neuropsychological testing is often the centerpiece. A neuropsychologist administers standardized tests measuring memory, attention, processing speed, executive function, and other abilities, then compares the results against what would be expected for that person’s age, education, and history. Objective deficits documented this way are difficult for an insurer to wave off, because the testing is designed to detect both genuine impairment and exaggeration.
2. Advanced imaging may also play a role. Depending on the case, treating physicians may order MRI studies or newer imaging techniques that can detect changes a routine CT misses. Whether advanced imaging is appropriate is a medical decision, but when it exists, it can become powerful evidence.
3. Treating specialists’ records matter as much as any single test. Ongoing care with a neurologist, consistent therapy notes, and a documented treatment course show an injury that is real, persistent, and being actively managed, not a one-time complaint.

How the insurance company will push back

It helps to know the arguments in advance, because the evidence above is built to answer them:

• “The scan was normal.” Answered by neuropsychological testing, treating records, and medical explanation of what standard imaging can and cannot detect.
• “The symptoms are from something else.” Prior medical records and consistent documentation from the first days after the crash tie the change in function to the collision.
• “It was just a mild concussion.” Testing, treatment history, and before-and-after witnesses show the actual effect on daily life, whatever the classification.
• “There was a gap in treatment.” Steady, documented care is the answer here, which is why following through on referrals and appointments protects both health and claim.

How we approach brain injury cases

The Hoffmann Law Firm has handled motor vehicle injury cases in St. Louis since 1998. Brain injuries are among the catastrophic injuries from motor vehicle crashes that we treat with particular care, because the proof has to be assembled deliberately and the recovery has to account for a future that may look different than the past.

That means identifying every available source of insurance recovery, including the at-fault driver’s liability coverage and, where the facts support it, uninsured or underinsured motorist coverage under your own policy, and building the medical and economic proof to pursue the maximum available insurance recovery. When the injuries are serious, you should talk directly with Attorney Christopher Hoffmann about your case.
