Bossier City Brain Injury Lawyers

TBI Classification and the Glasgow Coma Scale

GCS TBIs are classified as mild, moderate, or severe using the Glasgow Coma Scale, and that classification determines what medical evidence your case requires and how damages are calculated. Emergency responders assign a GCS score within minutes of the accident.

Mild TBI carries a GCS of 13 to 15. These are the hardest cases to prove. Standard CT scans often appear normal even when real brain damage exists. Persistent post-concussion syndrome produces headache, memory problems, and cognitive slowing that can last for months or years. Insurance adjusters rely on "normal imaging" to challenge these claims. Your case depends on neuropsychological testing and clinical documentation, not just radiology reports.

Moderate TBI is scored 9 to 12. Hospitalization is typical. Cognitive deficits are common and measurable. These cases require both imaging evidence and neuropsychological documentation of functional impairment. Moderate TBI often results in partial or full disability that a vocational expert must quantify.

Severe TBI scores 3 to 8. Permanent disability is the likely outcome. Long-term care costs routinely exceed six figures and can reach millions depending on the injured person's age and functional losses. A life care plan is required to document those costs for the jury. Ask any attorney you are considering whether they have experience retaining certified life care planners and whether they have prepared severe TBI cases for trial. The answer tells you whether they have handled cases at this level.

How Do Traumatic Brain Injuries Happen in Bossier City?

Bossier City produces specific accident patterns that generate TBI claims. Understanding the mechanism of your injury matters because it determines liability theory, evidence sources, and the defendants your attorney pursues.

The I-20 corridor through Bossier City is a consistent source of high-impact vehicle crashes. Ramp merges at Airline Drive and the Benton Road interchange create high-speed convergence points where inattentive and impaired drivers cause head-on and side-impact collisions. The forces in highway-speed crashes are sufficient to cause coup-contrecoup and diffuse axonal injury patterns even when occupants are belted. Vehicle accident TBIs follow the negligence standard under La. C.C. art. 2315, using evidence of traffic violations, distracted driving, and impaired operation.

The casino district along the Red River generates premises liability and DUI-related TBI claims. Bossier City's casino corridor is one of the most active commercial districts in north Louisiana. Parking structure falls, valet-related incidents, and impaired drivers leaving the district all create Bossier-specific fact patterns. Premises liability falls at commercial properties fall under La. C.C. arts. 2317 and 2322, requiring proof that the property owner knew or should have known of the hazardous condition.

Active construction at the perimeter of Barksdale Air Force Base produces falling object and heavy equipment accidents. Workers injured on construction sites may have both a workers' compensation claim and a third-party tort claim against the general contractor or equipment manufacturer. Those are separate legal actions with different procedures. The Louisiana Products Liability Act at La. R.S. 9:2800.51 governs defective equipment claims and requires proof that the product was unreasonably dangerous in its construction, design, or failure to provide adequate warnings.

When you talk to any attorney about your TBI case, ask them to identify all potential defendants. A car crash may have a driver defendant and an employer if the driver was on the job. A construction fall may have a general contractor, a subcontractor, and an equipment manufacturer. Missing a defendant at the outset can limit your recovery. See our construction site accident practice for more on multi-party workplace claims.

Coup-Contrecoup Injuries and Diffuse Axonal Injury

Coup-Contrecoup Standard CT scans miss two of the most common and serious TBI patterns in high-speed crashes: coup-contrecoup injury and diffuse axonal injury.

Coup-contrecoup occurs when the brain impacts the skull at the point of force and then rebounds to strike the opposite skull wall. Two separate injury sites result from one collision. Neither site may produce visible bleeding on CT. Without advanced imaging, these injuries are invisible to standard emergency workup.

DAI Diffuse axonal injury results from rotational forces during rapid acceleration or deceleration. Axons throughout the brain stretch and tear. The damage is diffuse rather than focal. This is a primary cause of long-term cognitive disability in TBI survivors and is common in both highway crashes and construction falls.

MRI with DTI or SWI can document DAI when conventional imaging is negative. Functional MRI and PET scans document altered brain metabolism in regions that appear structurally normal on standard sequences. When neuropsychological testing shows cognitive deficits and imaging is inconclusive, the combination of testing modalities is what builds the evidentiary case.

Insurance adjusters routinely use "normal CT" findings to contest TBI severity and payment. Ask any attorney you are considering how they handle the "normal CT" defense. A prepared attorney has a protocol: specific imaging sequences requested, a neuroradiologist retained to interpret them, and a neuropsychologist engaged to document the functional impact. Morris & Dewett engages neuroradiologists and neuropsychologists early in complex TBI cases specifically to counter this defense before it gets traction.

Long-Term Consequences of Moderate and Severe TBI

Cognitive impairment, personality changes, seizure disorder, and post-traumatic headache are the most common long-term outcomes after moderate or severe TBI. Each has direct legal consequence for damages.

Cognitive impairment encompasses memory loss, executive function deficits, and processing speed reduction. These are measurable through standardized neuropsychological testing. Impairment in any of these domains may prevent the injured person from returning to their prior occupation or performing at the same level. The vocational expert translates those functional deficits into an economic calculation: what the person earned before, what they can earn now, and the difference projected over their remaining working years.

Personality changes after TBI are documented but often underestimated by insurers. Disinhibition, aggression, and emotional dysregulation are neurological consequences of frontal lobe injury. They are documented by the treating neuropsychologist and often corroborated by family member observations. These changes affect not only the injured person's employment but also their relationships. Loss of consortium claims under La. C.C. art. 2315 allow spouses and family members to recover for the loss of companionship and support caused by TBI-related personality change.

Post-traumatic epilepsy affects an estimated 10 to 15 percent of severe TBI survivors. A seizure disorder requires lifelong anticonvulsant management and may impose driving restrictions, occupational limitations, and ongoing medical costs. The life care planner projects these costs over the injured person's lifespan.

Post-traumatic headache is the most common complaint after TBI. Chronic daily headache syndrome develops in a significant percentage of TBI patients. It limits work capacity and often requires specialist management indefinitely.

Ask any attorney you are considering how they approach life care planning in moderate and severe TBI cases. The life care plan is the financial document that translates long-term consequences into recoverable damages. An attorney without experience engaging certified life care planners is working without the primary damages tool in these cases.

Proving a TBI Case in Louisiana: Medical Experts

IME Proving a TBI case requires a coordinated team of medical experts, not a single treating physician. The insurance company will retain its own experts. Your case depends on being better organized.

The neurologist is the foundation of the medical case. The neurologist establishes the diagnosis, documents the causal mechanism, and testifies to how the injury connects to the accident. For mild TBI where imaging is normal, the neurologist also testifies to the clinical diagnostic criteria that Louisiana courts accept under La. C.C. art. 2315.

The neuropsychologist administers standardized cognitive testing. This produces objective, measurable documentation of deficits in memory, attention, executive function, and processing speed. The neuropsychologist also counters defense claims that deficits preexisted the accident. Validity testing and population norm comparisons for the person's age and education level close that defense argument.

The life care planner translates the medical picture into a dollar figure for future care. This includes specialist visits, medications, rehabilitation therapy, occupational and speech therapy, and personal assistance costs projected over the injured person's remaining life expectancy. For severe TBI, lifetime care costs documented in life care plans routinely run into seven figures.

The vocational rehabilitation expert quantifies loss of earning capacity. This expert reviews occupational history, functional limitations, and labor market data. The economist converts the vocational expert's findings into a present-value number for the jury.

The accident reconstructionist establishes the forces involved in the collision. In TBI cases, this expert calculates the acceleration and deceleration forces applied to the occupant's head and links those forces to the injury threshold for the documented TBI type. This closes the causation gap that defense experts try to exploit.

Willis-Knighton Bossier Health Center handles initial trauma workup for most Bossier City TBI cases. Emergency department records, CT reports, and initial GCS documentation from Willis-Knighton Bossier Health Center are primary evidence. For patients requiring complex neurosurgical care, transfer to Ochsner LSU Health Shreveport is the standard referral path. Ochsner LSU Health is the nearest Level I trauma center. Those neurosurgical records become the medical backbone of the case.

Ask the attorney how quickly they move to obtain and preserve medical records from the treating facilities. Records get harder to subpoena and easier to lose over time. Morris & Dewett sends medical record requests and preservation demands to treating facilities within days of engagement on catastrophic injury cases.

What Does Louisiana Law Allow You to Recover After a TBI?

Louisiana TBI damages fall into three categories: economic, non-economic, and punitive.

Economic damages cover past and future medical expenses, lost wages, and loss of earning capacity. Future medical costs include neurologist visits, specialist care, psychiatric treatment, occupational therapy, speech therapy, medications, and permanent personal assistance if needed. A certified life care planner documents these costs over the injured person's remaining life expectancy.

La. R.S. 9:2800.27 Louisiana's 2024 tort reform under La. R.S. 9:2800.27 changes how past medical expenses are calculated. Recoverable medical damages are now limited to amounts actually paid, not the amounts originally billed. Since hospital bills are routinely inflated well above the accepted payment amount, this reform reduces the past medical damages figure presented to the jury. An attorney who is not accounting for this reform in their damages calculation is working from an outdated model. Ask any attorney you speak with how they build past medical damages under La. R.S. 9:2800.27.

Non-economic damages cover physical pain, cognitive impairment, personality change, loss of enjoyment of life, and mental anguish. These damages are not capped in Louisiana personal injury cases outside of medical malpractice. Loss of consortium under La. C.C. art. 2315 allows spouses and eligible family members to recover separately for the loss of companionship and support the TBI has caused them.

Punitive damages apply under La. C.C. art. 2315.4 when intoxication caused the accident that produced the TBI. The jury determines the punitive amount based on the defendant's culpability.

Comparative Fault Louisiana's comparative fault rule changed as of January 1, 2026. Under the current version of La. C.C. Art. 2323, if you are found 51% or more at fault for the accident, you recover zero. Insurance adjusters build their entire defense strategy around pushing the plaintiff's fault percentage above 50%. Ask any attorney how they address comparative fault analysis in TBI cases, specifically in high-speed highway crashes where fault is disputed. Morris & Dewett works with accident reconstructionists from the outset of catastrophic injury cases to establish fault percentages before the defense builds its counter-narrative.

Filing Deadlines and the 26th Judicial District Court

TBI claims in Bossier Parish are filed in the 26th Judicial District Court at 204 Burt Blvd, Benton, Louisiana, with a deadline that depends on when the accident occurred.

For accidents on or after July 1, 2024, the Prescriptive Period deadline is two years under La. C.C. Art. 3493.11. For accidents that occurred before July 1, 2024, the old one-year deadline under La. C.C. art. 3492 still applies. This distinction matters for clients who were injured in late 2023 or early 2024 and are still within their window.

The discovery rule applies narrowly in Louisiana. Delayed onset of TBI symptoms does not automatically extend the prescriptive period. Louisiana courts require that the injury be truly latent and that the plaintiff had no reason to know of the injury to benefit from discovery rule tolling. An attorney who tells you the clock starts when you discover your injury without explaining the specific legal standard for latency is giving you incomplete advice.

High-value TBI cases in the 26th Judicial District Court typically involve extensive discovery: medical record subpoenas, imaging review depositions, expert witness depositions, and Daubert hearings to challenge or defend expert methodology. Most significant TBI cases are tried before six-person Bossier Parish juries, though the majority resolve before reaching trial.

An attorney who is vague about filing deadlines, the discovery rule, or what changes occurred in 2024 is not the attorney for a catastrophic injury case. These are not obscure details. They are the foundation of your case timeline.

Frequently Asked Questions

My CT scan was normal. Can I still have a compensable TBI under Louisiana law?

Yes. Louisiana courts allow TBI recovery based on clinical diagnosis when imaging is normal, provided the causal mechanism is established and alternative explanations are ruled out. A GCS below 15 at the scene, documented post-concussion symptoms, and neuropsychological testing showing measurable cognitive deficits are the evidentiary foundation for mild TBI claims with normal imaging. The key is having the right specialists document the clinical picture early in treatment. Morris & Dewett retains neuroradiologists for advanced imaging review (DTI, SWI) and neuropsychologists for standardized cognitive testing to build this evidentiary record in cases where standard CT is normal.

How long do I have to file a brain injury lawsuit in Bossier Parish?

For accidents on or after July 1, 2024, you have two years under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=1250735). For accidents before that date, the old one-year deadline under La. C.C. art. 3492 still applies. The prescriptive period runs from the date of injury, not the date you received a diagnosis or completed treatment. Missing the deadline bars the claim permanently. Contact an attorney as soon as possible to confirm which deadline applies to your specific accident date.

What does Louisiana's 2024 medical damages reform (La. R.S. 9:2800.27) mean for my TBI case?

Louisiana's 2024 reform limits recoverable past medical damages to amounts actually paid or accepted, not the amounts originally billed. Hospital charges are routinely several times higher than the amounts accepted from insurance or other payers. This reform reduces the past medical number presented to the jury. Future medical damages are not affected by this reform. They are still calculated using projected full costs from a certified life care plan. An attorney must understand and apply this reform correctly to build an accurate damages model.

What medical experts do I need to prove a traumatic brain injury claim?

At minimum: a neurologist to establish diagnosis and causation, and a neuropsychologist to document cognitive deficits through standardized testing. For moderate to severe TBI, add a certified life care planner for future medical costs and a vocational rehabilitation expert for loss of earning capacity. Complex liability cases also require an accident reconstructionist to establish the biomechanical forces linking the accident to the injury. High-value TBI cases routinely involve five or more expert witnesses. The insurance company will retain its own experts. Your case depends on having experts who can withstand Daubert challenges in the 26th Judicial District Court.

Does Louisiana's comparative fault rule affect TBI claims?

Yes. Under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109387) as amended effective January 1, 2026, if you are found 51% or more at fault for the accident, you recover nothing. Insurance adjusters in TBI cases routinely build defenses around pushing the plaintiff's fault above 50%. This is particularly common in highway crash cases where speed, lane position, and driver behavior are contested. An accident reconstructionist engaged early can lock in the physics of the crash before the defense constructs an alternative narrative.

What is diffuse axonal injury and why does it matter in a TBI case?

Diffuse axonal injury is the widespread tearing of nerve fiber connections throughout the brain caused by rotational acceleration and deceleration forces. It is one of the primary causes of long-term cognitive disability after TBI. Standard CT scans routinely miss DAI. MRI with diffusion tensor imaging (DTI) or susceptibility-weighted imaging (SWI) is required to document it. If your treating physician has not ordered advanced imaging sequences and you have ongoing cognitive symptoms after a negative CT, ask about DTI and SWI. Documented DAI changes the damages picture substantially: it is objective evidence of structural brain injury that correlates with the long-term cognitive and functional deficits that drive the damages calculation.

What is the difference between a life care plan and a vocational report in a TBI case?

A life care plan, prepared by a certified life care planner, projects the cost of all future medical care: specialist visits, rehabilitation therapy, medications, adaptive equipment, and personal assistance over the injured person's remaining life expectancy. A vocational rehabilitation report, prepared by a vocational expert, quantifies the reduction in earning capacity caused by the TBI's functional limitations. These are separate documents that address different damage categories. Both are typically required in moderate and severe TBI cases. The economist converts both into present-value figures for the jury.

Can my family members file a claim related to my TBI?

Yes. Spouses and eligible family members may file a loss of consortium claim under [La. C.C. art. 2315](https://legis.la.gov/legis/Law.aspx?d=109265). This is a separate legal action from the injured person's own personal injury claim. It compensates family members for their own losses: the loss of companionship, affection, and support caused by the TBI. Loss of consortium claims are particularly significant in severe TBI cases where personality changes and cognitive impairment alter family relationships substantially. Contact an attorney to determine which family members qualify to file and how the claim interacts with the primary personal injury action.
