Traumatic brain injury (TBI) claims in Louisiana: case value, filing deadline, settlement framework.

Traumatic brain injury (TBI) cases in Louisiana: the framework

A traumatic brain injury (tbi) claim in Louisiana sits at the intersection of two bodies of law: the medical-evidence rules that govern traumatic brain injury (tbi) diagnosis and causation, and the Louisiana-specific procedural rules that govern when the case can be filed, who can be sued, and how damages are calculated. Both bodies of law have to be navigated to convert the underlying injury into a recovery.

On the medical side, traumatic brain injury (tbi) (concussion, post-concussive syndrome, mild traumatic brain injury, mTBI) is typically treated through neurological evaluation, neuropsychological testing, cognitive rehabilitation. mild tbi may resolve in 3 to 12 months; moderate to severe tbi can produce permanent cognitive, emotional, and physical impairment. On the legal side, Louisiana applies the pure comparative negligence rule and a 2-year filing deadline. The combination of these two frameworks drives the case-value range and the procedural timeline for any specific case.

Louisiana filing deadline for traumatic brain injury (tbi) cases

Under La. Civ. Code art. 3493.1 (extended from 1 year to 2 years by 2024 La. Acts No. 423, effective July 1, 2024). Wrongful death remains 1 year under La. Civ. Code art. 2315.2., Louisiana requires traumatic brain injury (tbi) cases to be filed within 2 years of the date of injury. The clock starts on the date the injury accrued, with limited exceptions for minors (tolled until age of majority), mental incapacity, and (in some circumstances) the discovery rule for injuries that could not reasonably have been discovered at the time.

For traumatic brain injury (tbi) specifically, the discovery rule can matter when symptoms develop or worsen after the initial incident. Serious injuries often produce symptoms immediately, but late-developing complications can extend the documented treatment timeline; the SOL clock starts on the incident date in nearly all cases.

For comparison, the medical-malpractice SOL in Louisiana is 1 year and the wrongful-death SOL is 1 year from death. Each follows its own accrual rules.

Comparative-fault rule applied to traumatic brain injury (tbi) cases

Beating the SOL is necessary but not sufficient. A Louisiana jury will also be asked to apportion fault , and the result determines how much of your damages you actually recover.

Louisiana applies pure comparative negligence. Louisiana uses pure comparative negligence: recovery reduced by percentage of fault, even up to 99%. For traumatic brain injury (tbi) cases, the comparative-fault analysis typically focuses on the moments leading up to the underlying incident: whether the plaintiff contributed to the conditions that produced the injury, whether seat-belt or other safety equipment was used, and (in slip-and-fall and similar cases) whether the plaintiff was reasonably attentive to the surroundings.

Traumatic brain injury (TBI) medical evidence required in Louisiana

Neurological evaluation, neuropsychological testing, cognitive rehabilitation. Mild TBI may resolve in 3 to 12 months; moderate to severe TBI can produce permanent cognitive, emotional, and physical impairment.

For Louisiana courts, traumatic brain injury (tbi) cases require certain core categories of medical evidence: imaging or diagnostic testing tied to the incident date, a treating physician's causation opinion, treatment continuity records, and (for permanent-impairment cases) a functional-capacity evaluation. Each of these addresses a specific defense argument and supports a specific category of damages.

Evidence preservation in Louisiana traumatic brain injury (tbi) cases

In Louisiana, the evidentiary burden in a contested personal-injury case is borne by the plaintiff. That practical reality drives the procedural strategy: secure medical records via written authorizations on day one, preserve physical evidence with chain-of-custody documentation, depose witnesses while memories are fresh, and use the formal discovery tools (interrogatories, requests for production, depositions) aggressively. Defendants in Louisiana routinely file motions for summary judgment based on evidentiary gaps; the plaintiff who has built a complete record from the start is the one who survives those motions.

Settlement timeline for Louisiana traumatic brain injury (tbi) cases

The settlement timeline in Louisiana is driven by three factors: treatment duration, liability strength, and the at-fault carrier's historical practice. State Farm and Allstate cases in Louisiana routinely settle 30-60 days after a demand package is submitted; GEICO and Progressive cases often take longer because of their reserve-setting protocols. Cases involving Berkshire-owned carriers (GEICO) or self-insured fleet defendants typically require litigation filing to break the settlement deadlock.

Expert testimony in Louisiana traumatic brain injury (tbi) cases

In Louisiana appellate practice, the most frequently challenged expert testimony involves causation: did the defendant's conduct cause the injury, or would the injury have occurred anyway? Defense experts routinely argue that the plaintiff's injury is degenerative or pre-existing; plaintiff's experts must build a counter-narrative anchored in objective imaging, comparative pre-injury baseline data, and the temporal proximity of symptoms to the incident date.

Claim process specific to Louisiana

The standard Louisiana claim process treats the at-fault carrier as the first source of recovery. If that policy is inadequate, secondary sources include the plaintiff's own UM/UIM coverage, any applicable umbrella policies, and (in third-party-defendant cases) the assets of co-defendants. Each tier requires separate notice, separate documentation, and separate negotiation strategy. Missing a notice deadline on any tier can extinguish that source of recovery entirely.

Mistakes that reduce Louisiana traumatic brain injury (tbi) case value

Three avoidable errors recur in Louisiana personal-injury cases: settling the property-damage claim without coordinating release language, missing the pre-suit notice deadline for any government-defendant component of the case, and undervaluing future-medical damages because the plaintiff did not get a life-care plan or a vocational expert. Each of these errors can transform a high-value case into a low-value one.

Insurance considerations for traumatic brain injury (tbi) cases in Louisiana

Louisiana requires minimum liability coverage of 15/30/25 (La. Rev. Stat. § 22:1295). UM coverage is optional in Louisiana but most policies include it at the 15/30 level.

For traumatic brain injury (tbi) cases involving substantial medical bills (which is common with moderate to severe injuries), the at-fault driver's liability policy is often exhausted before damages are fully covered. UM/UIM coverage on the injured party's own policy becomes the operative source of recovery, which is why verifying available coverage on every potential policy source is the first procedural task in any moderate-to-serious case.

Frequently asked questions: Traumatic brain injury (TBI) in Louisiana

How long do I have to file a traumatic brain injury (tbi) lawsuit in Louisiana?

2 years from the date of injury under La. Civ. Code art. 3493.1 (extended from 1 year to 2 years by 2024 La. Acts No. 423, effective July 1, 2024). Wrongful death remains 1 year under La. Civ. Code art. 2315.2.. Shorter notice deadlines apply for government defendants.

What is the typical settlement range for traumatic brain injury (tbi) in Louisiana?

Typical range: $50,000 to $5,000,000+ depending on severity, permanence, and life-care plan. Louisiana-specific values depend on the comparative-fault allocation, the strength of medical evidence, and the at-fault carrier's claim-handling pattern.

Will my comparative fault reduce my traumatic brain injury (tbi) recovery?

Louisiana uses pure comparative negligence: recovery reduced by percentage of fault, even up to 99%. Your recovery is reduced proportionally to your fault percentage.

What medical evidence is needed for traumatic brain injury (tbi) in Louisiana?

Neurological evaluation, neuropsychological testing, cognitive rehabilitation. Louisiana courts also require a causation opinion from the treating physician and treatment continuity through maximum medical improvement.

Are there damage caps on traumatic brain injury (tbi) cases in Louisiana?

Authority: La. Rev. Stat. § 40:1231.2.
