This page helps Louisiana crash victims recognize common concussion signs, understand urgent danger symptoms, and follow a practical “first days” protocol that protects health and preserves documentation for an insurance claim.
A concussion after a car accident is easy to miss—especially when you don’t lose consciousness and you’re focused on your vehicle, your kids, or getting home. But headaches, dizziness, nausea, sleep disruption, and “brain fog” can show up quickly or build over hours.
Our goal is to help you protect your health and avoid early mistakes that insurers use to minimize brain-injury claims. We are not built for volume. We are built for leverage. Speed + evidence preservation + insurer-insider knowledge + trial-ready preparation = The Babcock Benefit. “Insurer-insider knowledge” here means understanding how adjusters attack concussions (no LOC, normal CT, delayed symptoms) and building documentation that answers those predictable defenses.
If you suspect a concussion, take it seriously—even when the crash “didn’t look that bad.”
If you are inside the first 72 hours, call (225) 500-5000 or use the free case review form before evidence changes.

What a concussion is (and how crashes cause them)
A concussion is a type of traumatic brain injury that can happen after a blow or jolt to the head—and also after an injury to another part of the body that transmits force to the head—an important point explained by Johns Hopkins Medicine.
Concussions don’t always look dramatic. According to CDC, mild TBI/concussion symptoms can involve physical, thinking, mood, and sleep changes—so “it’s just a headache” can be an incomplete picture.
Leverage Note: If you can do it safely, document the crash forces (photos of interior contact points, airbag deployment, headrest position). That is what we mean by leverage—mechanism-of-injury evidence matters when symptoms are subjective.
Common concussion signs after a crash
Concussion symptoms can include headache, nausea/vomiting, dizziness, trouble thinking or remembering, mood changes, and sleep changes, as listed by Johns Hopkins Medicine.
CDC groups concussion symptoms into categories like physical (headache, dizziness), cognitive (difficulty concentrating), emotional (irritability), and sleep-related issues, which CDC explains for mild TBI/concussion.
Danger signs: when to go to the ER or call 911
Call 911 or go to an emergency department if you notice danger signs like a worsening headache, repeated vomiting, unusual behavior or increased confusion, slurred speech, weakness/numbness, seizures, or inability to wake up—because CDC lists these as reasons to seek emergency care after a mild TBI/concussion.
A practical first-48-hours concussion protocol
- Get evaluated. If you suspect concussion symptoms, medical assessment is the safest move—especially if symptoms are worsening.
- Have someone check on you. Monitoring matters because symptoms can evolve after you leave the crash scene.
- Prioritize rest (body and brain). Rest is a core part of concussion recovery, as Merck Manual (consumer) explains in its overview of concussion treatment.
- Avoid alcohol and high-risk activities. Driving, alcohol, and heavy stimulation can be risky early in recovery, which Merck Manual highlights when discussing early concussion management.
- Use a symptom log. Note headaches, dizziness, sleep, light sensitivity, memory or attention problems, and what triggers worsening.
Leverage Note: Don’t “tough it out” in silence and then try to reconstruct symptoms later. This is why we focus on early documentation—consistent symptom progression is harder for insurers to dismiss.
Return to driving, work, school, and sports
Many people want a single rule like “wait X days,” but concussion recovery varies. Johns Hopkins notes that symptoms may last less than a day or linger longer, and can occur right away or worsen over minutes or hours after injury, as explained by Johns Hopkins Medicine.
From a practical standpoint, your return to normal activity should be guided by medical advice and symptom response—not by insurance pressure to “get back to normal.”
Testing and imaging: what scans can (and can’t) prove
Imaging can be important to rule out bleeding or other structural problems, but concussion itself may not show up as “damage” on a scan. The MSD Manual (Merck Manual Consumer Version) notes that CT/MRI may be needed to make sure brain structures are not damaged—and if there is no structural damage, treatment focuses on symptoms.
That’s why a normal CT the day of the crash does not automatically mean “no concussion,” and it’s also why symptom documentation and follow-up can matter as much as the initial ER workup.
Documentation that protects both your health and your claim
- Symptom timeline: when headaches started, dizziness episodes, sleep changes, nausea, sensitivity to light/noise.
- Function notes: missed work, slowed thinking, difficulty driving, increased fatigue.
- Witness notes: family/friends who observed confusion, irritability, or unusual sleepiness.
- Medical follow-up: discharge instructions, referrals, PT/vestibular therapy notes if ordered.
For safety, remember that vehicle safety systems reduce risk but don’t eliminate concussion risk in real-world crashes, consistent with how NHTSA discusses occupant protection and airbag systems.
What we see in practice
What we see is that insurers commonly downplay concussions with a few predictable talking points: “no loss of consciousness,” “normal CT,” “you didn’t mention it at the scene,” or “you’ve had headaches before.” We also see pressure for an early recorded statement that locks in a symptom description before the injured person understands what they’re experiencing.
Leverage Note: We try to prevent the claim from becoming a debate about credibility instead of evidence. This is why we preserve the timeline and the proof early—before the defense narrative gets a head start.
Talk to a lawyer quickly if…
- your symptoms are worsening or you have any danger signs (health comes first)
- a child is involved (kids may not describe symptoms clearly, and documentation is critical)
- a government vehicle/employee may be involved (special procedures can apply)
- fault is disputed or you’re being blamed for the crash
- you’re being pushed to sign a release while symptoms are still developing
If the crash may involve a federal employee acting within the scope of work, 28 U.S.C. § 2675 generally requires presenting an administrative claim before filing a lawsuit.
The administrative presentment rules (including what counts as a presented claim) are addressed in 28 C.F.R. Part 14, which is why deadline-spotting early matters when government actors are involved.
Louisiana Law Snapshot (Updated 2026)
Two-year delictual prescription: Most Louisiana injury cases have a two-year prescriptive period running from the day the injury is sustained under La. Civ. Code art. 3493.1. In concussion cases, waiting can also create proof problems because symptoms, timelines, and records become harder to tie down.
Comparative fault and the 51% bar (effective Jan. 1, 2026): Under the current text of La. Civ. Code art. 2323, fault is allocated among responsible persons, and if the injured person is 51% or more at fault, they cannot recover damages; if under 51%, damages are reduced proportionally. Concussion claims are especially sensitive to credibility and consistency—so evidence and documentation often drive fault and value.
Free case review: protect your timeline, your evidence, and your options
We are not built for volume. We are built for leverage. Concussion cases require disciplined documentation and early evidence preservation so that your symptoms aren’t rewritten as “stress” or “just headaches.” The Babcock Benefit, in plain English, is early triage and preservation paired with trial-ready preparation if the insurer won’t deal fairly.
Next step: Call (225) 500-5000 or complete the free case review form at the bottom of the page. The urgency is practical: video overwrites, vehicles get repaired, witnesses disappear, and the insurance narrative hardens while concussion symptoms are still evolving.
These items are helpful to have with you when you call, but do not delay calling because you do not have them. If you have them handy, keep them nearby for the call.
- Crash date/time and location (if known)
- Your ER/urgent care visit info (if you went) and discharge paperwork (if you have it)
- A short list of symptoms and when each started
- Photos/video from the scene and vehicle interior (airbag, headrest position, contact points)
- Insurance information (if available)
Call today if…
- you have worsening headache, repeated vomiting, confusion, or any danger signs
- your employer requires you to drive or operate machinery and symptoms are interfering
- the insurer is asking for a recorded statement right now
- you’re being blamed for the crash or fault is disputed
- a government or commercial vehicle is involved
What happens next
- We triage evidence (video, vehicle data, witness contacts, medical timeline) and identify what must be preserved immediately.
- We spot deadlines and special procedure triggers early (including government-claim processes when applicable).
- We set an insurer contact strategy that protects you from narrative traps while your medical picture is documented and stabilized.
