The injury that gets missed
Traumatic brain injuries are routinely missed in the first hours after an accident. The emergency department is focused on what is life threatening and visible. A patient who is talking and oriented, with a CT scan that shows no bleed, is discharged with instructions and no diagnosis.
The symptoms arrive afterward. Headaches, light and noise sensitivity, sleep disruption, trouble concentrating and remembering, word-finding difficulty, irritability, and an exhaustion that does not resolve with rest. Family members notice a change in the person before the person does.
This matters legally because the defense will point to the normal scan and the discharge without a diagnosis as proof that nothing happened. Standard imaging is not designed to detect diffuse axonal injury, and a normal CT rules out bleeding rather than ruling out brain injury.
Mild does not mean minor
The clinical term mild traumatic brain injury describes the presentation at the time of injury, not the consequences. A person with a mild TBI can be left unable to return to the work they did before, unable to tolerate an environment they managed easily, and changed in ways their family experiences daily.
That gap between the label and the lived reality is where these claims are won or lost. Evidence of how the person functioned before and how they function now, from people who knew them, does work that a medical chart alone does not.
How brain injuries are documented
Building a TBI case properly generally involves neurological and neuropsychological evaluation, cognitive testing that measures specific deficits against expected baselines, advanced imaging where clinically indicated, treating physician testimony, and lay testimony from family, colleagues and friends about the change they observed.
Where the injury is permanent, life care planning and vocational assessment establish the cost of future care and lost earning capacity. These are frequently the largest components of a serious brain injury claim, and they are not recoverable if the claim settles before they are established.
How they happen
Vehicle collisions of every kind, motorcycle and bicycle crashes, pedestrian impacts, falls from height and falls on the same level, being struck by falling objects, workplace and construction incidents, sports and recreation impacts, and assaults. A brain injury does not require the head to strike anything, because rapid acceleration and deceleration alone can produce it.
What to do if you suspect a brain injury
Get evaluated, and be specific about symptoms rather than minimizing them. Ask someone close to you what they have noticed, because self-assessment is unreliable with this injury. Keep a symptom journal with dates. Follow through on referrals to neurology and neuropsychology. Do not settle a claim while the picture is still developing.
Common Questions
Can you have a brain injury with a normal CT scan?
Yes. A CT scan is designed to detect bleeding, skull fracture and swelling that require immediate intervention. It does not rule out diffuse axonal injury or the functional deficits that follow a concussion. A normal scan is common in patients with significant ongoing symptoms.
How long do concussion symptoms last?
Many people improve within weeks. A significant minority experience symptoms lasting months or permanently, a pattern sometimes described as post-concussion syndrome. Persistent headaches, cognitive difficulty, mood changes and fatigue beyond the expected recovery window warrant neurological evaluation rather than waiting.
How do you prove a brain injury in a legal claim?
Through neuropsychological testing that measures specific deficits, treating physician opinion, advanced imaging where indicated, and testimony from people who knew the person before and after. The before-and-after evidence carries substantial weight because it shows change rather than describing symptoms.
Why do brain injury claims take longer?
Because the permanence of the injury cannot be assessed until recovery plateaus, and the largest components of the claim are future care and lost earning capacity. Settling before the medical picture stabilizes means accepting a number that does not account for what the injury turns out to cost.
