How Do You Prove a Brain Injury in Arizona?

Posted on July 3, 2024 in

MRI of the brain after traumaEvery year, millions of lives are affected by traumatic brain injuries (TBIs). Brain injuries, often of a catastrophic nature, can stem from various accidents, including car wrecks, slips and trips and falls, workplace incidents, and other events. Even a seemingly mild or moderate head injury can lead to significant consequences for one’s health. However, in order to recover fair compensation for it, multiple aspects need to be proven. This is hard: TBIs are called the “invisible injury” by lawyers and insurers because they often do not show up on MRIs or other diagnostic testing, and most physicians and hospitals do not document this type of injury very well because the insurance industry does not like to pay for mild TBI treatment.

The U.S. government provides this information about “mild” TBI symptoms often being subtle, hard to define, etc.:  https://www.cdc.gov/traumatic-brain-injury/signs-symptoms/index.html

The National Institute of Health website indicates these factors for TBI:

Initial symptoms: Headache, dizziness, confusion, and fatigue tend to start immediately after an injury but resolve over time. Emotional symptoms such as frustration and irritability tend to develop during recovery.

Seek immediate medical attention if the person experiences any of the following symptoms, especially within the first 24 hours after an injury to the head:

Physical symptoms of TBI

  • Headache
  • Convulsions or seizures
  • Blurred or double vision
  • Unequal eye pupil size or dilation
  • Clear fluids draining from the nose or ears
  • Nausea and vomiting
  • New neurological problems, such as slurred speech, weakness of arms, legs, or face, or loss of balance

Cognitive/behavioral symptoms of TBI

  • Loss of or change in consciousness for anywhere from a few seconds to a few hours
  • Decreased level of consciousness (e.g., hard to awaken)
  • Confusion or disorientation
  • Problems remembering, concentrating, or making decision
  • Changes in sleep patterns (e.g., sleeping more, difficulty falling or staying asleep, inability to wake)
  • Frustration, irritability

Perception and sensation symptoms of TBI

  • Light-headedness, dizziness, vertigo, or loss of balance or coordination
  • Blurred vision
  • Hearing problems, such as ringing in the ears
  • Unexplained bad taste in the mouth
  • Sensitivity to light or sound
  • Mood changes or swings, agitation, combativeness, or other unusual behavior
  • Feeling anxious or depressed
  • Fatigue or drowsiness; a lack of energy or motivation

Types of Evidence That Can Be Used to Prove a Traumatic Brain Injury (TBI) in Arizona

Proving a brain injury is a crucial step in finding justice and fair compensation. To build a robust case, your attorney will gather a variety of compelling evidence. This may include:

Medical Records

The foundation of proving a brain injury lies in comprehensive medical records. Seek immediate medical attention after an accident and make sure that all diagnostic tests, imaging, and evaluations related to the brain injury are documented.

Expert Medical Testimony

Engaging medical experts who specialize in neurology or traumatic brain injuries can provide authoritative testimony. Their expert opinions can substantiate the existence, severity, and long-term implications of the brain injury.

Treatment Plans and Rehabilitation Records

Documenting the treatment plan and rehabilitation process is essential. This includes therapy sessions, medications, and any other interventions prescribed to manage the effects of the brain injury.

Employment and Education Records

Establishing the impact of the brain injury on an individual’s ability to work or pursue education is crucial. Your lawyer may collect employment records, academic transcripts, and any documented changes in performance or capabilities.

Witness Statements

Statements from witnesses who observed the incident leading to the brain injury or noticed changes in the individual’s behavior afterward can provide additional perspective and corroborate the circumstances.

Photographic and Video Evidence

If available, photographic or video evidence of the incident or aftermath can be compelling. This visual documentation can support the narrative of how the brain injury occurred and its immediate aftermath.

Journal Entries and Personal Records

Encourage individuals affected by the brain injury to keep personal records or journals detailing their experiences, struggles, and the impact on their daily lives. These personal insights can provide a human perspective to the legal proceedings.

Neuropsychological Testing

Neuropsychological tests can measure cognitive function and identify deficits resulting from a brain injury but is regularly disputed as “subjective.” These test results can be valuable in establishing the extent of impairment.


The most common defense to a TBI claim is the lack of “objective” evidence: why doesn’t the TBI show up on the MRI or brain scan, etc.? Some specialized neurological experts can potentially assist, such as one of our cases involving a TBI that caused vision problems. We retained a neuro-ophthalmologist, whose testing and opinions provided objective evidence, so the insurer paid up only after getting close to the trial date.

Long-Term Prognosis and Life Care Plans

Getting input from medical professionals regarding the long-term prognosis and potential need for ongoing care is vital. Life care plans outlining the anticipated medical, rehabilitation, and support needs can contribute to the overall case. Often the future damages are the heart of the damages case.
