TBI — more common and more serious than people realize.

The CDC estimates 1.5 million Americans sustain a traumatic brain injury each year. About 230,000 are hospitalized. Roughly 50,000 die. The remainder — over a million people per year — sustain mild to moderate TBIs that they may not even recognize at the time. Many will deal with lifetime cognitive, emotional, and physical effects that they never connect back to the original injury.

TBIs are classified by severity using the Glasgow Coma Scale (GCS) and other clinical indicators:

  • Mild TBI (concussion) — GCS 13-15, loss of consciousness less than 30 minutes (or no LOC at all), post-traumatic amnesia less than 24 hours. Often invisible on initial CT scans. Symptoms can be persistent and life-changing.
  • Moderate TBI — GCS 9-12, LOC 30 minutes to 24 hours, post-traumatic amnesia 1-7 days. Frequently visible on CT or MRI. Significant ongoing cognitive and emotional impacts.
  • Severe TBI — GCS 3-8, LOC over 24 hours, post-traumatic amnesia over 7 days. Visible structural damage. Often life-changing or fatal.

The legal challenge: mild TBI — by far the most common — is also the easiest for defense experts to dismiss. The injury frequently doesn't show on standard imaging, the symptoms are non-specific (headaches, fatigue, memory problems, irritability, sleep disturbance, mood changes), and the symptoms can be attributed to depression, anxiety, age, or normal life stressors. Building these cases requires specific evidence.

The proof problem — and how we solve it.

Modern TBI litigation depends on a layered evidence approach:

1. Acute medical records

Emergency department records, EMS records, and initial hospital records establish what happened in the immediate aftermath — GCS scores, observed symptoms, immediate testing, and any documentation of loss of consciousness or post-traumatic amnesia. Even brief notations ("appeared dazed," "could not recall accident," "complains of headache") are valuable.

2. Advanced imaging

Standard CT scans miss most mild TBIs. Specialized imaging may detect damage:

  • 3T MRI with DTI (Diffusion Tensor Imaging) — can show diffuse axonal injury invisible on standard MRI
  • fMRI (functional MRI) — shows brain activation patterns; abnormalities suggest dysfunction even without structural damage
  • SPECT scans — though controversial in litigation, can show areas of decreased perfusion consistent with TBI
  • PET scans — similar metabolic imaging

3. Neuropsychological testing

A comprehensive neuropsychological battery — administered by a qualified neuropsychologist over 6-8 hours — is the gold standard for documenting cognitive deficits. The testing covers attention, memory, executive function, processing speed, language, and visual-spatial skills. Properly administered, it produces an objective profile that distinguishes TBI from depression, malingering, or other causes.

4. Treating provider testimony

Neurologists, neuropsychologists, physiatrists, and rehab therapists who treated the patient over time become powerful witnesses. They can speak to the consistent presentation of symptoms, the response to treatment, and the prognosis.

5. Lay witness testimony

Family members, friends, coworkers who observed the person before and after the injury are often the most powerful witnesses for the jury. The cognitive and emotional changes that show up in everyday life — the executive function failures, the personality changes, the new irritability or fatigue — these are what convince jurors.

Defense strategies in TBI cases.

TBI cases attract specific defense tactics that experienced plaintiff's counsel anticipates:

The "no LOC, no TBI" argument

Defense attorneys frequently argue that without loss of consciousness, there could not have been a TBI. This is medically incorrect — many mild TBIs occur without LOC. But it's a frequent jury argument.

The pre-existing condition argument

Defense will look for any pre-existing condition — depression, anxiety, prior concussion (high school football, prior car accident), ADHD, learning disability, headaches, sleep issues — and argue that the current symptoms are pre-existing rather than caused by the injury. Comprehensive treating history is the response.

The "secondary gain" / malingering argument

Defense will hire neuropsychologists who specialize in "validity testing" — designed to identify malingering. Properly designed plaintiff neuropsychological batteries include the same validity measures and produce results that show the patient was giving genuine effort.

The depression/anxiety attribution

Defense will argue that the cognitive symptoms are caused by depression or anxiety related to the litigation, the financial stress, or unrelated life events. This is where treating history and longitudinal symptom tracking become critical.

The IME (independent medical examination) trap

Defense IMEs frequently produce reports that minimize symptoms, attribute them to other causes, or find no objective findings. These reports need to be cross-examined carefully. The IME examiner is paid by the defense, has typically built a career on defense work, and has standard report templates.

Damages — what TBI cases recover.

TBI case damages vary dramatically by severity and circumstances. Categories of damages typically include:

Past and future medical expenses

Initial emergency and inpatient care; rehab services; ongoing neuropsych care; medications; assistive devices. For moderate-to-severe TBIs, the future medical expenses are typically the largest economic damages category and are projected using a life-care plan.

Lost wages and earning capacity

For mild TBIs, cognitive deficits frequently mean lost productivity and reduced earning capacity even when the person can still work. For moderate-to-severe, the person may be unable to return to their pre-injury career or unable to work at all. Vocational experts calculate the differential.

Life-care plan projections

For moderate-to-severe TBIs, a life-care plan projects medical care, equipment, attendant care, home modifications, and other long-term needs. See our Future Medical Care guide.

Pain and suffering / mental anguish

TBI affects emotional regulation, mood, and quality of life in ways that produce significant pain and suffering damages. The "loss of self" — the awareness that the person is no longer who they were before — is its own category of suffering.

Loss of consortium

Available to spouses for the loss of relationship caused by the TBI.

Punitive damages

Where the conduct that caused the TBI involved gross negligence (DUI, knowing safety violations, etc.), subject to Texas's CPRC § 41.008 cap.

Typical settlement ranges

  • Mild TBI with full recovery — $100,000-300,000
  • Mild TBI with persistent post-concussive syndrome — $300,000-1,500,000
  • Moderate TBI with significant ongoing deficits — $1,500,000-5,000,000
  • Severe TBI with permanent disability — $5,000,000-25,000,000+

Actual values depend on age, pre-injury earnings, insurance coverage, and the strength of liability evidence.
