Traumatic brain injury (TBI) claims are among the most complex personal injury cases in Texas — not because a different legal framework applies, but because TBI symptoms can be delayed, cumulative, and life-altering in ways that affect everything from the statute of limitations to how damages are calculated. This page explains the Texas-specific legal issues that come up in a TBI claim, regardless of what caused the injury.
What Counts as a Traumatic Brain Injury
TBI covers a wide severity range — from a mild concussion with symptoms resolving in days or weeks, to moderate injuries with longer recovery, to severe TBI involving permanent cognitive, physical, or personality changes. Common causes in Dallas include car accidents, truck accidents, motorcycle crashes, and falls. Because symptoms of milder TBI aren’t always visible on standard imaging and can take time to fully present, these cases raise a legal issue that more obvious injuries don’t: when does the filing clock actually start?
The Discovery Rule and TBI Claims
Texas’s general statute of limitations for personal injury claims is two years under Civil Practice & Remedies Code § 16.003, running from the date of the injury. But Texas recognizes a discovery rule exception: in Childs v. Haussecker(Tex. 1998), the Texas Supreme Court held that the limitations clock can be tolled — paused — until the plaintiff knew, or through reasonable diligence should have known, of the injury, particularly for latent injuries that don’t present immediately.
This matters directly for TBI: if concussion symptoms don’t fully emerge until weeks after an accident, or a diagnosis is delayed, the discovery rule may extend when the two-year period actually begins. This is a narrow, fact-specific exception — courts still enforce the general two-year deadline strictly — so documentation of when symptoms appeared and when they were medically connected to the accident is critical if this issue comes up.
Additional Tolling Provisions Relevant to Severe TBI
Two other Texas provisions specifically matter in serious brain injury cases:
- “Unsound mind” tolling — under Tex. Civ. Prac. & Rem. Code § 16.001(a)(2), if a person is of unsound mind at the time a claim accrues, the statute of limitations is tolled until they regain capacity. Severe TBI cases involving impaired cognitive function can implicate this provision.
- Minors — the statute of limitations is tolled for minors until they turn 18, giving them until age 20 to file a personal injury claim, which matters for a child who suffers a TBI.
Comparative Negligence and TBI Claims
TBI claims are still subject to Texas’s modified comparative negligence rule under Civil Practice & Remedies Code § 33.001 — recovery is available as long as the injured person’s share of fault doesn’t exceed 50%, with total compensation reduced proportionally to their percentage of fault. This applies regardless of the type of accident that caused the brain injury.
Why TBI Damages Are More Complex
Severe TBI cases frequently involve damages categories that simpler injury claims don’t: long-term or lifetime medical care, cognitive rehabilitation, lost future earning capacity (particularly significant when a TBI affects someone’s ability to return to their prior occupation), and life care planning to project decades of future costs. Because these projections require medical and vocational expert testimony, TBI cases are typically more resource-intensive to litigate than a straightforward soft-tissue injury claim.
What To Do If You Suspect a TBI After an Accident
- Seek medical evaluation even if you feel fine immediately after the accident — many TBI symptoms (headaches, memory issues, mood changes, difficulty concentrating) can take hours or days to appear.
- Follow up on any recommended imaging or specialist referrals, and keep records of every appointment.
- Document changes in cognitive or physical function over time, not just at the moment of injury.
- Note the date symptoms first appeared and when they were medically diagnosed — this timeline can matter if the discovery rule becomes relevant later.
- Consult a Texas attorney promptly rather than waiting to see if symptoms resolve, since the general two-year deadline still applies unless a specific exception is later shown to apply.

Frequently Asked Questions
What if my TBI symptoms didn’t show up until weeks after my accident?
This is exactly the situation the discovery rule addresses. Texas courts have recognized, in cases like Childs v. Haussecker, that the statute of limitations can be tolled until a latent injury is discovered or reasonably should have been discovered — though this is a narrow exception, not a general extension, so prompt medical documentation matters.
Does a mild concussion count as a traumatic brain injury for a legal claim?
Yes — TBI covers a full severity spectrum, including mild concussions. The legal framework (comparative negligence, statute of limitations, damages) is the same regardless of severity, though the value and complexity of a claim typically scales with the injury’s severity and long-term impact.
How long do I have to file a TBI claim in Texas?
The general rule is two years from the date of injury under Civil Practice & Remedies Code § 16.003. The discovery rule, unsound-mind tolling, or minor tolling provisions can extend this in specific circumstances, but the standard deadline still applies unless one of those exceptions is established.
Can I still recover damages if I had a prior head injury?
Generally yes. Texas law doesn’t bar recovery just because you had a pre-existing condition — a defendant is generally responsible for the extent to which their conduct worsens a pre-existing condition, though proving what portion of the current injury is attributable to the new incident can require careful medical expert testimony.
Why do TBI cases often take longer to resolve than other injury claims?
Because damages frequently depend on long-term prognosis, cognitive and vocational impact, and future care needs, TBI cases often require extensive medical documentation and expert input before their full value can even be assessed — which can extend the timeline compared to a claim with more immediately apparent injuries.
