A brain injury can change how a person thinks, works, sleeps, communicates, and relates to family. Some injuries are obvious on the first hospital scan. Others are not. Either way, the legal case must show what changed, why it changed, and what the injured person will need in the years ahead.
Houston brain injury lawyer Greg Baumgartner has represented seriously injured Texans since 1985. Baumgartner Law Firm keeps a limited caseload so Greg can stay personally involved. We investigate the event, preserve evidence, develop the medical proof, and document the daily losses that an insurance company may try to dismiss.

Quick answer: A brain injury claim may be valid even when a CT or MRI does not show the injury. The CDC explains that a brain scan is not required to identify a mild TBI or concussion. The claim should be built from the complete evidence – symptoms, medical evaluations, witness observations, work changes, testing, and the facts of the accident.
A broken bone can usually be seen on an X-ray. A brain injury may reveal itself through forgotten appointments, lost words, poor concentration, headaches, anger, exhaustion, or a personality change that only the family notices. Those effects are real, but they are easy for an insurer to label as stress, age, medication, or a pre-existing condition.
That is why these cases cannot be handled like routine claims. The lawyer must connect the force of the event to the medical history and then show how the person functioned before and after the injury. The evidence often comes from several sources, not a single test.
Greg’s perspective: After four decades of serious-injury work, I have learned that the most important brain-injury witness is often someone who knew the client well before the accident. A spouse, coworker, friend, or supervisor can explain the change in a way that a stack of medical records cannot.
Baumgartner Law Firm’s published results include a $3.75 million recovery in a closed-head-injury case arising from a high-speed rear-end collision involving several defendants. Past results do not predict the outcome of another case. They do show why disputed head-injury claims require careful preparation and a willingness to litigate when responsibility or causation is denied.
CT and MRI scans are important tools, but they do not answer every question. A CT scan may identify bleeding, swelling, or a skull fracture. MRI can provide more detail in appropriate cases. Yet a person may still have a mild traumatic brain injury or concussion without an abnormal routine scan.
The National Institute of Neurological Disorders and Stroke describes CT and MRI as commonly used imaging tools in TBI evaluation. The CDC’s mild-TBI guidance goes further: a scan is not needed to identify a mild TBI or concussion and may instead be used when there is concern about bleeding or another serious condition.
A lawyer should never diagnose a brain injury. That belongs to qualified medical professionals. Our job is to ensure the legal case does not reduce a complicated injury to a single line in a radiology report.
A traumatic brain injury, or TBI, is an injury that disrupts how the brain works. It may be caused by a blow or jolt to the head, a penetrating injury, or a blow to the body that causes the head and brain to move rapidly. A person does not have to strike a windshield or lose consciousness for doctors to consider a TBI.
The word ‘mild’ describes the initial medical classification; it does not promise a mild impact on someone’s life. Many people improve, but some continue to experience headaches, memory trouble, dizziness, sleep problems, or emotional changes. Moderate and severe injuries may cause extended unconsciousness, major cognitive or physical limitations, and a need for long-term supervision or care.
For a focused discussion of mild TBI, see our guide to concussions after an accident. When the injury permanently affects independence, employment, or daily function, it may also qualify as a catastrophic injury claim.
Symptoms vary from person to person and may not all appear immediately. The CDC’s list of mild-TBI and concussion symptoms includes problems involving physical health, thinking, memory, emotions, and sleep.
Medical warning: Some signs after a head injury require emergency care. Review the CDC’s concussion danger signs and call 911 or seek emergency help when appropriate. This page provides legal information, not medical advice.
The goal is not to collect the largest possible stack of records. It is to build a clear, reliable picture of what happened and how life changed. Depending on the case, that work may include:
Neuropsychological testing can evaluate areas such as attention, memory, processing speed, language, and executive function. It can be useful, but it is not a magic answer. Results must be interpreted by a qualified professional and considered alongside education, work history, language, prior conditions, effort, medications, sleep, pain, and the rest of the medical evidence.
We do not tell doctors what diagnosis to make. We gather the records, understand the opinions, and ensure the insurance company addresses the full medical picture rather than selecting only the evidence that supports its defense.
Brain injuries can result from many preventable events. Common claims we evaluate include:
The person who caused the immediate event may not be the only responsible party. A negligent driver, trucking company, employer, contractor, property owner, maintenance company, product manufacturer, or other business may share liability. Identifying every responsible party matters because a severe brain injury can create losses far beyond one insurance policy.
We investigate corporate relationships, contracts, training, maintenance, safety rules, insurance coverage, and the decisions that led to the injury. In a fatal case, eligible family members may also have rights under Texas law. Our Houston wrongful death lawyer page explains those claims in more detail.
There is no honest average value for a brain injury case. The value depends on the diagnosis, the person’s function before and after the injury, the expected recovery, future care, earning history, liability evidence, available insurance, and many other facts.
Recoverable damages may include:
One of the most serious mistakes is settling before the medical outlook is clear. A release usually ends the claim for good. If memory, fatigue, balance, behavior, or work problems continue after settlement, the injured person generally cannot return for additional money.
Greg’s perspective: The question is not simply, ‘What were the medical bills?’ The harder question is, ‘What will this injury take from this person over the rest of a working life?’ That is where careful preparation matters most.
Brain injury claims are often defended aggressively because the future damages can be substantial. Common arguments include:
A good response is evidence, not adjectives. We compare the pre-injury and post-injury record, examine the medical timeline, identify witnesses, and address alternative explanations directly. Pretending a prior condition never existed can damage credibility. The better approach is to show what was stable before the event and what objectively changed afterward.

Under Texas Civil Practice and Remedies Code Section 16.003, many personal-injury lawsuits must be filed within two years after the claim accrues. Different deadlines, notice requirements, and exceptions can apply, especially in claims involving government entities, minors, or unusual facts.
Do not treat the general two-year rule as permission to wait. Video can be erased, vehicles and equipment can be repaired, witnesses can disappear, and the early medical history can become harder to reconstruct.
Texas uses proportionate responsibility. Under Section 33.001 of the Texas Civil Practice and Remedies Code, a claimant generally cannot recover if the claimant is more than 50% responsible. When the claimant is 50% or less responsible, the recovery is generally reduced by that percentage.
Insurance companies understand that shifting blame can reduce what they pay. We investigate the event before accepting an adjuster’s version of fault.
Houston has important resources for people living with brain injuries. TIRR Memorial Hermann’s brain injury rehabilitation program provides inpatient and outpatient rehabilitation for people with different levels of brain injury. Texas Health and Human Services also provides information about acquired brain injury programs, resources, and support.
These links are provided as public resources and do not imply an affiliation or medical recommendation. Treatment choices should be made with qualified healthcare professionals.
Yes. A normal routine scan does not necessarily rule out a mild traumatic brain injury or concussion. The CDC explains that a scan is not required to identify a mild TBI. Diagnosis and legal proof should be based on the complete medical and factual record.
No. Loss of consciousness can be important evidence, but it is not required in every TBI diagnosis or legal claim. A medical professional should evaluate the symptoms and history.
The value depends on the severity and duration of the injury, future medical and support needs, lost earning capacity, the impact on daily life, the strength of the liability evidence, available insurance, and the person’s individual circumstances. A responsible evaluation requires records and investigation, not an online average.
Possibly. A prior condition does not automatically defeat a claim. The key question is whether the event caused a new injury or worsened an existing condition. The before-and-after medical and functional evidence is especially important.
The available claim depends on who caused the injury and whether the employer carries workers’ compensation. A negligent contractor, property owner, equipment company, driver, or other third party may be responsible. A Texas non-subscriber employer may also face a direct negligence claim. These cases require an early review of the employment and insurance relationships.
There is no single timetable. A claim should not be resolved before the medical condition and future needs are understood well enough to value the loss. Serious injury, disputed fault, several defendants, expert work, insurance disputes, or litigation can extend the case. Many lawsuits settle before trial, but preparation should not assume that outcome.
There is no upfront attorney fee. We handle accepted brain injury cases on a contingency-fee basis. The firm is paid an attorney fee only if we recover compensation. The written agreement explains the fee and case-expense terms.
A brain injury case should be built around the person who was changed by the accident – not an insurance company’s early estimate. If you or a family member suffered a serious head injury in Houston or elsewhere in Texas, Baumgartner Law Firm is ready to listen and explain the next steps.
