Loss of consciousness and a trip to the emergency room make a brain injury obvious. Plenty of them are not. A person gets rattled in a rear-end collision, feels fine by evening, and turns up four days later with headaches and mood swings and gaps where names used to be. Those cases start with no record at all. 

The CDC counted more than 69,000 TBI-related deaths in 2021, about 190 a day, and says plainly that the figure leaves out every TBI treated only in an emergency department, urgent care or a doctor’s office, along with the ones nobody treats at all. The injuries this article is about are the ones that never reach that count. 

The Injury Has to Be Proven Before Fault Ever Comes Up

According to a New Haven personal injury attorney, getting harmed due to another person’s negligent actions could lead to a visit to the emergency room. But you can file a personal injury claim against the person or entity responsible for your injury.

Every negligence claim rests on the same four elements. A duty of care was owed. It was breached. The breach caused the injury. Real damages followed. The civil standard is a preponderance of the evidence, which means more likely than not and sits considerably below what a criminal case demands. 

That fourth element is where a brain injury claim gets expensive to prove and expensive to lose. 

What the Medical Record Has to Show

Some head impacts cause a subdural hematoma, blood pooling between the dura and the layer beneath it. A small one may call for monitoring and repeat scans. A larger one, or one that shifts the midline, often means surgery soon, before pressure does damage that cannot be undone.

This is one of the more dangerous forms of brain injury out there, and doctors have known for decades that the outlook gets worse the older the patient is and the longer treatment gets delayed. Every hour matters here in a way it doesn’t with most injuries.

Then there’s brain swelling, which is its own kind of emergency. When it’s severe enough, patients sometimes need intensive treatment just to keep pressure inside the skull from climbing to a point where it starts causing more harm than the original injury did. That gap between the incident and a complete picture is exactly why prompt treatment matters to a claim filed months later. A symptom logged at the first visit is evidence. The same symptom raised for the first time in month four invites an argument that something else produced it.

Where the Claim Is Filed Changes the Math

Comparative fault moves the final number more than most claimants expect, and the rules are not uniform across states. In Connecticut, a plaintiff generally cannot recover if their share of negligence is greater than the combined negligence of the defendants. In a case involving one defendant, that means a plaintiff who is 50% at fault can still recover, while a plaintiff who is more than 50% at fault cannot. Any recovery is reduced according to the plaintiff’s percentage of fault. 

Connecticut runs two clocks. A negligence claim must be brought within two years of when the injury was sustained or reasonably should have been discovered, and no claim may be brought more than three years after the act or omission. The second deadline does not move for late discovery, which is the one that catches people whose symptoms took a year to document.

What a Jury Cannot See on a Scan

Cognitive and behavioral change is the hardest part of a brain injury for a jury to hold onto, and it is also the part no imaging study puts on a screen. Family testimony about who the person was before. Experts who can turn a scan into plain English. Day-in-the-life video showing what getting dressed now takes.

Getting a serious TBI diagnosed early can make a real difference, both for treatment and for documenting what happened. Early medical care creates a record of symptoms and changes that may otherwise be difficult to connect to the injury later. 

Brain injury lawyers W. Douglas Easton and the team at Easton & Easton recognize that documenting not only the medical diagnosis but also the ways a brain injury affects everyday life can be important when seeking to hold the responsible party accountable. None of that replaces the medical record. It fills in the parts of the injury a scan was never going to show, which is most of what the person and their family are actually living with.

The throughline across every brain injury claim, whatever state it sits in, is documentation started early and kept consistent. These cases are won or lost on whether the record reflects what happened inside somebody’s skull, and that record gets built in the days right after the injury or it does not get built at all.
