Proving a brain injury claim takes medical records that document the trauma, imaging and neuropsychological testing that measure its effects, symptom documentation from the people around you, and expert opinions that connect the injury to the accident. No single document carries the case. These claims are built from a body of proof assembled over months, because the damage is often invisible on a scan and the symptoms are easy for an adjuster to dismiss. A Maryland brain injury attorney puts that record together before an insurer defines it for you.
Why a Normal Scan Does Not Mean You Are Not Injured
Insurers lean hard on a clean CT scan. The U.S. Food and Drug Administration likewise recognizes the diagnostic limits of mild traumatic brain injuries. Despite advances in imaging and other testing, more sensitive and objective methods to detect mild TBI are still needed, and no device should be used by itself to diagnose a traumatic brain injury.
Timing makes the problem worse. Federal health officials note that some symptoms may appear right away while others may not appear for hours or days after a mild brain injury. So an emergency room visit on the night of a fall, a worksite accident, or a collision can generate a record that looks reassuring and is simply incomplete. Everything that comes after that visit is what fills the gap.
The Medical Records That Anchor the Diagnosis
The medical file is still the foundation, and the strongest files show a continuous line from the moment of impact to the current diagnosis. Federal researchers describe the two standard scans this way: CT imaging can show a skull fracture and any brain bruising, bleeding, or swelling, while MRI is more sensitive and can pick up more subtle brain changes that a CT scan may miss.
Most well-documented claims contain records like these:
- Emergency department and first responder notes describing the blow to the head, plus any loss of consciousness, confusion, or disorientation at the scene
- The initial CT imaging and any later MRI ordered once symptoms persisted
- Referrals to a neurologist, neuropsychologist, or rehabilitation specialist, and the notes those providers generate
- Therapy records from physical, occupational, and speech therapy
- A treatment timeline with no unexplained gaps between the injury and the diagnosis
Gaps in that timeline are the first thing a defense adjuster looks for. A three-month stretch with no appointments becomes an argument that you recovered, or that something else caused your symptoms.
What Neuropsychological Testing Adds
When imaging is unremarkable, but the deficits are real, formal cognitive testing is often what makes the injury measurable. Neuropsychological tests are frequently used alongside imaging after a mild brain injury to assess memory, concentration, information processing, executive functioning, reaction time, and problem solving.
The value of that testing in a claim is that it converts a complaint into a number. Instead of telling an adjuster that you cannot concentrate, a neuropsychology evaluation shows where your processing speed and recall fall against expected performance. Testing done closer to the injury, and repeated later, also documents whether the deficits are improving or settling in permanently.
Documenting the Symptoms No Machine Records
Some of the most persuasive proof in a brain injury case never appears in a chart. Federal health officials warn that these symptoms can be difficult to sort out because they resemble other health problems, that a person may not recognize or admit they are having problems, and that the difficulties may be overlooked by the injured person, their family members, or their healthcare provider.
That is why the record you build yourself matters:
- A dated symptom journal noting headaches, dizziness, memory lapses, irritability, and sleep changes
- Statements from a spouse, parent, coworker, or supervisor who can describe what you were like before and what changed
- Employment records showing missed shifts, reduced duties, written warnings, or a demotion after the injury
- School records for an injured student, including grades and accommodations
- Photographs, texts, and messages that fix the timeline of when problems started
Collected as the months pass, that material becomes the before-and-after comparison that testimony alone cannot supply.
How Maryland Decides Whether Your Expert Can Testify
None of this evidence reaches a jury on its own. Someone qualified has to connect the accident to the injury, and Maryland courts screen those opinions before the jury hears them. In 2020, in Rochkind v. Stevenson, Maryland’s highest court adopted the Daubert standard as the governing standard by which trial courts admit or exclude expert testimony, overruling the older general acceptance test.
Under that standard, a judge may consider whether:
- The expert’s theory or technique can be and has been tested
- It has been subjected to peer review and publication
- The particular scientific technique has a known or potential rate of error
- It is generally accepted
A court can also ask whether the expert unjustifiably extrapolated from an accepted premise to an unfounded conclusion, and whether obvious alternative explanations were adequately accounted for. The list is not closed, and no single factor decides the question. As Maryland’s highest court put it, quoting the United States Supreme Court, a court may conclude that there is simply too great an analytical gap between the data and the opinion proffered.
The practical lesson is that a brain injury expert has to show the reasoning, not just the credentials. A physician who says the accident caused your deficits without explaining how the data supports that conclusion is the kind of opinion a defense lawyer moves to exclude at a pretrial hearing.
Fault Evidence Carries Extra Weight in Maryland
Medical proof is only half the case. Maryland remains a contributory negligence state, and its highest court reaffirmed that rule in 2013 when it declined to replace it with the comparative fault system most states use. If your own negligence proximately contributed to your injuries, you can be barred from recovering anything at all.
That rule turns ordinary liability evidence into something a brain injury claimant cannot afford to lose. Scene photographs, measurements, damage patterns, maintenance and inspection records, surveillance footage, and independent witnesses are the material that answers a blame-shifting defense, and much of it disappears within weeks.
Maryland also generally requires a civil action at law to be filed within three years from the date it accrues, unless another provision of the Code sets a different period. Claims against a government entity can carry separate notice requirements. Three years sounds generous until you realize the proof has to be preserved long before then.
