What is the deadline to file a brain injury lawsuit in Louisiana?

For accidents occurring on or after July 1, 2024, the prescriptive period is two years from the date of injury under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=109560), enacted by Act 423. For accidents that occurred before July 1, 2024, the old one-year prescriptive period still applies. Confirming which deadline governs your case requires verifying the accident date against that effective date. Missing the deadline permanently ends your right to file.

What is the difference between a mild TBI and a severe TBI in legal terms?

Mild TBI (concussion, GCS 13-15) typically requires neurologist and neuropsychologist testimony and focuses on documented cognitive deficits and post-concussion syndrome. Severe TBI (GCS 3-8) involves DAI or coup-contrecoup injuries, often requires a full life care plan projecting decades of medical costs, and supports significantly larger non-economic damages because of permanent disability. The severity classification affects which experts are needed, what discovery is ordered, and what a jury is likely to award.

Does a concussion qualify as a traumatic brain injury for a legal claim?

Yes. A concussion is classified as a mild traumatic brain injury. It occurs when the brain impacts the inner skull wall, which can happen in low-speed collisions. Insurance companies often treat concussions as minor injuries, but documented post-concussion syndrome with persistent cognitive and physical symptoms supports a legitimate personal injury claim. Neuropsychological testing that quantifies the deficits is the key evidence for these cases.

What medical experts does a Monroe TBI case require?

At minimum: a neurologist or neurosurgeon to establish the medical diagnosis, a neuropsychologist to conduct cognitive baseline testing and document deficits, and a biomechanical engineer to connect the accident forces to the injury mechanism. Moderate to severe TBI cases also require a life care planner to project future care costs and a vocational expert to calculate loss of earning capacity. Without these experts, damages are speculative and juries have nothing concrete to award.

Can I file a claim if my TBI symptoms appeared weeks after the accident?

Yes, but delayed onset creates a documentation challenge that the defense will exploit. Insurance adjusters and defense experts argue that a delay between the accident and the appearance of symptoms means the accident did not cause them. A neurologist can explain medically why some TBI symptoms emerge gradually and worsen over time. Early medical records from the accident date, even if they did not initially diagnose TBI, strengthen the timeline. Do not wait to establish the medical record.

What is a life care plan and why does it matter in a TBI case?

A life care plan is a document prepared by a certified medical professional that projects all future care needs for the injured person and the cost of each need over their remaining life expectancy. For moderate to severe TBI, it covers neurologist visits, neuropsychological evaluations, psychiatric care, physical and occupational therapy, medication, and in severe cases, permanent personal care assistance. Without a life care plan, juries cannot calculate future economic damages with any specificity. The plan is the foundation of the largest damages component in most serious TBI cases.

How does the 51% comparative fault rule affect my TBI claim?

Under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109387), which became effective January 1, 2026, if a jury finds you 51% or more at fault for the accident, you recover nothing. If you are 50% or less at fault, your award is reduced proportionally by your fault percentage. In TBI cases arising from vehicle accidents, the defense regularly argues that the plaintiff was speeding, not wearing a seatbelt, or otherwise contributed to the collision. Accident reconstruction and biomechanical evidence are the tools for countering those arguments.

What makes TBI claims harder to prove than other injury claims?

TBI claims require expert testimony at every stage: causation, severity, future care, and damages calculation. The injury itself is internal and often invisible on standard CT scans, particularly in DAI cases. Defense experts are routinely hired to challenge both the severity of the injury and its causal connection to the accident. Neuropsychological testing can be challenged as subjective. TBI symptoms also overlap with pre-existing conditions like depression, anxiety, and age-related cognitive changes. Defense counsel uses that overlap to attribute the deficits to something other than the accident. An attorney who does not regularly handle TBI cases will underestimate what the proof chain requires.

Monroe Brain Injury Attorneys

Brain injuries create legal situations that most personal injury cases don't. The medical evidence is complex. The long-term costs are hard to calculate. Defense experts challenge both the severity of the injury and whether the accident caused it. No one researches Monroe brain injury lawyers for fun. Something happened, and now you need real answers.

This page explains how traumatic brain injury claims work in Louisiana, what courts in the Fourth Judicial District expect, and what evidence determines the outcome. Morris & Dewett has handled TBI cases for over 25 years. Take your time. Do your research. Reach out when you're ready.

TBI Causes and Liability in Ouachita Parish

TBI cases in Monroe arise from several categories of negligence. Motor vehicle collisions on US-165 and I-20 produce brain injuries through sudden deceleration and rotational forces. Louisiana motor vehicle crashes send 2,490 people to emergency departments and result in 742 hospitalizations for TBI each year, according to Louisiana Department of Health data. Falls at commercial premises and construction sites account for even more.

Liability in Ouachita Parish follows Louisiana negligence law under La. C.C. Art. 2315. To hold someone responsible, you must prove they breached a duty of care that caused your injury. For vehicle accidents, that typically means a traffic law violation or unreasonably dangerous driving. For premises falls, it means the property owner knew or should have known about the hazardous condition. Product liability claims under the Louisiana Products Liability Act (La. R.S. 9:2800.52) apply when defective safety equipment failed to prevent the brain injury.

Workplace TBI claims add a layer. Workers compensation benefits are available regardless of fault. But if a third party other than your employer caused the accident, a separate tort claim is available alongside workers comp. The two proceedings run independently. Ask any attorney you consult whether they have experience handling both tracks simultaneously. It requires coordination that not every firm manages well.

TBI Classification and the Glasgow Coma Scale

Emergency physicians classify TBI severity using the GCS: mild (13-15), moderate (9-12), or severe (3-8). That classification shapes every downstream decision. It determines which expert witnesses you need, what diagnostic imaging is ordered, how the life care plan is structured, and what damages range a jury is likely to find credible.

Mild TBI, commonly called a concussion, occurs when the brain impacts the inner skull wall. It happens in low-speed crashes, contact sports, and falls. The injury isn't minor. Post-Concussion Syndrome affects a significant percentage of concussion patients and can last months or years. Insurance adjusters routinely treat concussions as two-week nuisances. That framing can cost clients real money.

Moderate TBI involves loss of consciousness lasting up to 24 hours and often produces permanent cognitive and physical changes. Severe TBI involves loss of consciousness exceeding 24 hours and typically results in conditions like DAI and coup-contrecoup injuries. Coup-Contrecoup injuries are particularly common in vehicle collisions and can be missed when only a single impact site is imaged.

Ask any attorney you speak with whether they understand the difference between a concussion and a moderate TBI for purposes of expert witness planning. An attorney who treats all TBI cases the same way will under-build the expert team for a moderate or severe case.

Proving Causation in a Monroe TBI Case

Causation is where TBI cases are won and lost. It's not enough to show you have a TBI and were in an accident. You must connect the specific mechanism of the accident to your specific brain injury diagnosis. Defense experts in Ouachita Parish cases regularly challenge both the severity of the injury and the causal link.

The proof chain typically requires several experts. An accident reconstruction specialist establishes the forces involved in the collision or fall. A biomechanical engineer calculates the forces applied to the skull and compares them to established injury thresholds from peer-reviewed research. A neurologist or neurosurgeon testifies on the medical plausibility of the TBI given those measured forces. A Neuropsychologist conducts baseline cognitive testing to quantify deficits and document changes from the person's pre-injury baseline.

Ask any attorney you speak with whether they have existing working relationships with neurologists, neuropsychologists, and life care planners. These relationships take years to build. An attorney without them is building the expert team from scratch for your case. Morris & Dewett has worked with the same network of TBI specialists for years. We know how they testify, what evidence they need, and how to counter defense experts who try to minimize documented injuries.

Long-Term Effects of Traumatic Brain Injury

Post-traumatic seizure disorders, cognitive impairment, and personality changes are documented long-term consequences of TBI that may not be fully apparent at the time of initial evaluation. Symptoms sometimes worsen or become apparent over months and years. This creates a documentation problem: if your legal claim resolves before the full picture emerges, you cannot reopen it. That is why the evaluation process matters as much as the treatment process.

Cognitive effects include memory loss, difficulty concentrating, and executive function decline that affects the capacity to work. Personality and behavioral changes are common: emotional dysregulation, increased irritability, depression, and anxiety can emerge after injuries that initially seemed manageable. Post-traumatic seizure disorders develop in 2 to 17 percent of closed-head TBI cases, sometimes appearing months after the initial trauma. Physical deficits including speech impediments, balance issues, chronic headaches, and insomnia complete the picture of how a brain injury affects daily life.

The Louisiana Department of Health's Office for Citizens with Developmental Disabilities (OCDD) provides services for Ouachita Parish residents living with severe TBI-related disabilities. Knowing these resources exist matters for long-term planning. It also matters legally: a Life Care Planner uses available treatment resources to build a credible, court-ready cost projection. Without that plan, juries have nothing concrete to award for future care.

Ask any attorney you consider whether they have worked with a life care planner on a TBI case before. Ask them to name the planner and describe how the plan was built. Vague answers mean they are guessing about costs that will define the case value.

Hospitals and Trauma Resources for Monroe TBI Patients

St. Francis Medical Center at 2700 Jackson St. in Monroe is the primary trauma facility for Ouachita Parish, and Glenwood Regional Medical Center at 503 McMillan Rd. in West Monroe provides emergency and surgical care. Where you receive initial treatment affects both your recovery and your legal case. For complex neurosurgical cases requiring advanced intervention, patients are typically referred to LSU Health Shreveport.

Early diagnosis at a trauma-capable facility creates the medical record that drives your legal case. Emergency admission notes, CT and MRI imaging, and neurology follow-up visits document the injury's existence, severity, and progression. Gaps in that record give defense insurers grounds to dispute the severity of the TBI. If you saw a primary care doctor but not a neurologist, that gap will be exploited. If you delayed treatment by weeks, expect the defense to argue the delay means the injury was minor.

The practical advice is straightforward: if you experienced any head impact in an accident, get evaluated at a facility capable of ordering appropriate imaging. Do not dismiss symptoms because they seem manageable in the first days after the injury.

What Compensation Does Louisiana Law Allow After a TBI?

Louisiana law allows full recovery of economic and non-economic losses in personal injury cases, subject to the 51% comparative fault bar. Economic damages cover past and future medical expenses including neurologist visits, neuropsychological evaluations, physical and occupational therapy, medications, and home care assistance for severe TBI. Future care costs for moderate to severe TBI are typically the largest component of an economic damages claim. A life care planner documents those costs over the plaintiff's remaining life expectancy.

Lost wages from missed work are recoverable. Loss of Earning Capacity damages compensate for permanent impairment that limits your ability to work at full capacity. This requires both a vocational expert and an economist to present to the jury.

Non-economic damages cover physical pain, cognitive impairment, personality change, and loss of enjoyment of life. Louisiana imposes no cap on non-economic damages in personal injury negligence cases. La. R.S. 9:2800.27 imposes a cap on medical malpractice cases only. If your TBI resulted from a vehicle accident, fall, or workplace incident, that cap does not apply. A loss of consortium claim under La. C.C. Art. 2315 is available to a spouse whose partner's TBI has substantially impaired the marriage.

Louisiana's Comparative Fault rule matters in TBI cases. Insurance adjusters build defenses around pushing the plaintiff's fault percentage above 50%. If you were, for example, not wearing a seatbelt or were exceeding the speed limit at the time of the collision, expect that to be used. Ask any attorney you speak with how they address comparative fault arguments specifically in TBI cases. For our case results, see the results page.

Filing a TBI Lawsuit at the 4th JDC

TBI lawsuits in Monroe are filed in the Fourth Judicial District Court, which serves Ouachita and Morehouse parishes. The court operates under Louisiana Code of Civil Procedure and follows the discovery rules that govern expert witness disclosure and depositions.

The Prescriptive Period for personal injury claims is two years under La. C.C. Art. 3493.11 for accidents occurring on or after July 1, 2024. If your accident happened before July 1, 2024, the old one-year deadline applies. Do not assume two years applies to every case without confirming the date against the effective date of Act 423.

That deadline is a hard cutoff. Missing it ends your claim permanently. If an attorney quotes you a filing deadline without first confirming your accident date against the July 1, 2024 effective date, that is a red flag. Morris & Dewett confirms prescriptive period calculations at intake.

Immediate steps after a brain injury matter legally: preserve medical records, imaging, employer records, and police or incident reports before memories fade and documents disappear. For workplace TBI cases, the workers compensation claim and any third-party tort claim run as separate proceedings with different deadlines. An attorney needs to manage both timelines simultaneously. The expert deposition phase typically involves the neuropsychologist, life care planner, vocational expert, and biomechanical engineer. Each deposition is an opportunity for defense counsel to challenge your experts. Preparation matters.
