Prior results do not guarantee a similar outcome.
You were told it was just a concussion. Weeks later, the headaches have not stopped, you cannot concentrate at work, and you feel like a different person. That gap between what you were told and what you are living through has a name: post-concussion syndrome.
Post-concussion syndrome, often shortened to PCS, is a condition in which the symptoms of a concussion continue past the point doctors expect them to resolve. It is not a second brain injury. It is the original concussion continuing to affect you long after the crash.
The symptoms cover a wide range. One person may have two of these; another may have most of them at once:
This is where the word “mild” becomes a problem. A concussion is sometimes labeled a mild traumatic brain injury in medical records, but that label describes the initial impact, not your daily reality. Mild is a relative term. It is in comparison to a “severe” brain injury, like a coma or no brain function. It does not mean the symptoms are mild and insignificant.
The functional impairment from PCS can be severe. People lose jobs over it. They stop driving. They withdraw from family life.
“You do not look injured” is one of the most damaging misconceptions in these cases. PCS does not show up on the surface. There is no cast and no visible wound. That invisibility is exactly what makes the condition easy for others to dismiss and hard for you to prove.
If you were told a concussion after a car accident in Louisiana was minor, but the symptoms persisted, you may be dealing with PCS rather than a concussion that simply ran its course.
Research published in StatPearls, NIH National Library of Medicine, estimates that approximately 15 percent of people who sustain a mild traumatic brain injury go on to develop post-concussion syndrome, though experts note that number likely understates the real picture because many cases go unreported or undiagnosed. That means PCS is common enough to take seriously and overlooked often enough to slip through the cracks.
Diagnosis usually involves a neurologist, neuropsychological testing, and a review of any imaging. There is no single scan that confirms PCS, which is precisely why your documentation matters so much.
A broken bone shows up on an X-ray. PCS shows up in the consistent record you and your doctors build over time. For more on the broader category of brain injuries from crashes, the Centers for Disease Control and Prevention publishes detailed traumatic brain injury data.
The question you typed into your phone was probably some version of “How long does this last?” It is a fair question, and the honest answer is: it depends on the person.
Doctors generally group recovery into three stages.
These are general ranges, not predictions about your individual recovery:
| Recovery Stage | Typical Duration | What It Means for Your Claim |
|---|---|---|
| Acute | Within 3 months | Expected recovery path; document everything even if improving |
| Persistent | 3 months to 1 year | Extended care required; claim value grows with documented duration |
| Chronic | Beyond 1 year | Long-term impairment; future care costs and lost earning capacity become major factors |
Recovery timelines vary considerably depending on the person. Age, history of prior head injury, and overall health all play a role. What the medical literature consistently shows is that a meaningful percentage of people do not follow the typical short recovery window. For those with persistent PCS, symptoms can continue to disrupt daily life, work performance, and personal relationships for months or years after the original injury.
Of those who develop PCS, roughly 10 to 15 percent continue to experience symptoms beyond one year. That is a significant group of people whose lives are altered well past the point an insurance adjuster expects them to be “back to normal.”
This matters for your claim in a direct way. The longer your symptoms persist, the more medical care you need, the more work you miss, and the more your quality of life is affected. Each of those consequences feeds into what is fair compensation and what your case is worth. A claim resolved before the full duration of your symptoms is known can leave real losses on the table.
If you want to understand the evidentiary side of this in more depth, we have written about proving mild traumatic brain injury in Louisiana, and PCS follows the same demands for careful documentation over time.
By the time you are reading this, an adjuster may have already told you your symptoms are “not that serious.” That is not a coincidence. It is a strategy.
Insurance companies dispute concussion claims because the condition gives them openings that a visible injury does not.
The table below shows the most common tactics and what they actually mean:
| Insurer Tactic | What They Argue | How to Counter It |
|---|---|---|
| Pre-existing condition | Your symptoms existed before the crash | Pre-accident medical records establish your baseline health |
| Subjective symptoms | Symptoms rely on self-report, not objective measurement | Neuropsychological testing documents functional deficits directly |
| Treatment gap | Delay in seeking care proves the injury was minor | Explain the delay through records; begin treatment immediately |
| Clean imaging | CT or MRI shows no injury | PCS is a functional disruption, not a structural one; imaging is not definitive |
| Surveillance evidence | A photo or social media post shows you appear fine | One moment does not reflect daily impairment; document every bad day |
| Insurer-selected IME | Their doctor found no PCS | Retain an independent neurologist for an objective evaluation |
They also use gaps in treatment against you. If you waited a week before seeing a doctor because you assumed the symptoms would fade, the insurer may argue the delay proves the injury was minor. The reality is that many people delay precisely because they were told it was just a concussion.
Insurers frequently arrange their own independent medical examination, often called an IME, with a doctor they select. That examination is not neutral in the way the name suggests. This is one reason a brain injury attorney retains independent neurologists and neuropsychologists to evaluate and document the condition on the injured person’s behalf.
If an insurance adjuster has already told you your concussion symptoms are not serious, you have every right to get a second opinion and a free consultation with a Louisiana brain injury attorney. Call the Ikerd Law Firm at (337) 366-8994.
If you are worried you waited too long to act, the deadline is the first thing to understand, and it is the thing too many people get wrong.
The prescriptive period depends entirely on the date of your accident:
| Accident Date | Governing Statute | Deadline to File |
|---|---|---|
| Before July 1, 2024 | La. C.C. art. 3492 (former rule) | 1 year from the date of the accident |
| July 1, 2024 or later | La. C.C. art. 3493.1 | 2 years from the date of the accident |
That distinction matters because the date of your accident determines which deadline applies to you. If you are unsure where your crash falls, an attorney can tell you quickly. You can also read our complete guide on how long to file a personal injury lawsuit in Louisiana for more on how these deadlines work.
Many people with PCS ask whether the clock starts later if their symptoms emerged after the crash. Louisiana’s general discovery doctrine may apply in limited circumstances where an injury was not and could not reasonably have been discovered at the time of the accident.
The specific application of that doctrine to delayed TBI and PCS symptoms is not settled, and the clock is generally treated as running from the date of the accident itself. Do not rely on the discovery exception to extend your deadline. Treat the accident date as the start of your timeline and act well before it expires.
Fault rules also changed recently, and the date of your crash determines which applies:
| Accident Date | Fault Rule | Effect on Your Recovery |
|---|---|---|
| Before January 1, 2026 | Pure comparative fault | You may recover even if mostly at fault; recovery is reduced proportionately |
| January 1, 2026 or later | Modified comparative fault (Act 15 of 2025) | Recovery is barred if your fault is found to be 51 percent or more |
PCS fits within Louisiana’s framework for brain injury damages the same way other injuries do. Louisiana places no statutory cap on general personal injury damages, so the value of a claim turns on what you can prove rather than an arbitrary ceiling.
You are not looking for a number you can plug into a calculator. You are trying to understand what actually goes into the value of a PCS claim, because the answer determines how much of your real loss you can recover.
| Damage Type | What It Covers | Who Establishes It |
|---|---|---|
| Medical expenses (past) | ER visits, neurologist, imaging, medication to date | Bills and treatment records |
| Medical expenses (future) | Ongoing treatment, therapy, and testing projected forward | Treating physician’s prognosis |
| Lost wages | Missed work, reduced hours, demotion tied to symptoms | Pay stubs, employer records |
| Loss of earning capacity | Long-term reduced ability to work due to PCS | Vocational expert testimony |
| Pain and suffering | Chronic headaches, mood changes, disrupted sleep | Personal account, medical documentation |
| Loss of enjoyment of life | Activities no longer possible due to symptoms | Journal entries, witness statements |
PCS attacks concentration, memory, and stamina, the exact abilities most jobs depend on. Document your sick days, any reduction in hours, and any change in role, demotion, or termination tied to your symptoms. A reduced ability to earn over time can be a larger loss than the wages you have already missed.
Expert testimony often determines whether these damages hold up. Neurologists and neuropsychologists establish the diagnosis and connect it to the crash.
Vocational experts explain how PCS limits your ability to work. Their written reports and depositions frequently determine whether an insurer will negotiate or a jury will award.

Post-concussion syndrome can resolve within a few months for some people, while others experience symptoms for a year or longer. Duration varies based on the severity of the initial injury, age, prior head injury history, and other health factors. There is no standard timeline, which is why documenting symptoms throughout recovery is critical to any legal claim.
Yes. Post-concussion syndrome is a recognized medical condition that qualifies as a compensable injury under Louisiana personal injury law. Economic damages, such as medical bills and lost wages, and non-economic damages, such as pain, suffering, and disrupted daily life, are both recoverable. The challenge is documentation. Having a neurologist or neuropsychologist formally diagnose and monitor PCS significantly strengthens a claim.
Post-concussion syndrome is a complex disorder in which concussion symptoms persist beyond the expected recovery window. Diagnosis typically involves a neurological examination, neuropsychological testing, review of imaging results, and evaluation of the injured person’s reported symptoms. There is no single test that confirms PCS, which is why consistent medical documentation matters.
If symptoms emerged or worsened in the days after the crash, document the change with your doctor immediately and contact an attorney as soon as possible. Louisiana’s general discovery doctrine may apply in limited circumstances, but its application to delayed PCS is not settled. Do not rely on it to extend your deadline.
Adjusters frequently argue that PCS symptoms are subjective, pre-existing, or inconsistent with the reported impact severity. They may rely on standard CT or MRI scans that show no injury, even though PCS often does not produce visible imaging findings. Independent neuropsychological evaluation is the most effective counterargument. Some new technologies, like DTI (diffusion tensor imaging to map nerve tracts) scans in sensitive MRI machines, can provide objective documentation of brain injuries causing PCS.
