Proving a 'Mild' Traumatic Brain Injury (MTBI) in New York Courts

What Is Mild Traumatic Brain Injury (MTBI)?

Mild traumatic brain injury (MTBI) -- also called concussion -- is a brain injury caused by a blow, jolt, or bump to the head (or by rapid acceleration/deceleration of the head) that disrupts normal brain function. MTBI is classified as mild based on the initial neurological presentation:

- Loss of consciousness: 30 minutes or less (or no loss of consciousness) - Alteration of mental status: Brief confusion, disorientation, or feeling dazed - Post-traumatic amnesia: Memory loss for events around the time of the injury, lasting less than 24 hours - Glasgow Coma Scale (GCS): Score of 13-15 (out of 15) at 30 minutes after the injury - Neurological deficits: No focal neurological deficits on initial examination

Despite the mild classification, MTBI can cause significant symptoms, including: - Physical symptoms: Headache, dizziness, nausea, fatigue, sensitivity to light and noise, sleep disturbances, blurred vision, ringing in the ears. - Cognitive symptoms: Memory problems, difficulty concentrating, slowed thinking, word-finding difficulties, impaired judgment. - Emotional and behavioral symptoms: Irritability, mood swings, anxiety, depression, apathy, personality changes.

The Myth of 'Mild' Brain Injury

The term mild traumatic brain injury is a source of significant misunderstanding -- both in the medical community and in the legal system. The classification is based on the initial neurological presentation, not on the severity of the symptoms or the long-term outcome. A person classified as having a mild TBI may suffer severe, persistent symptoms that significantly affect their ability to work, maintain relationships, and enjoy life.

Key points about the myth of mild brain injury:

- The classification is based on initial presentation, not outcome: A person with a brief loss of consciousness is classified as having a mild TBI, even if they suffer persistent symptoms for years. - MTBI symptoms can be severe and persistent: Many people with MTBI suffer from post-concussion syndrome (PCS), with symptoms lasting months or years. - MTBI can cause significant functional impairment: Cognitive impairments can affect the ability to work, drive, and perform daily activities. - MTBI can have cumulative effects: Repeated MTBIs (e.g., in athletes, military personnel, or accident victims) can cause cumulative brain damage, leading to chronic traumatic encephalopathy (CTE). - The injury may not show up on standard imaging: CT and standard MRI may appear normal in MTBI, even though the brain has been injured. This makes proving the injury challenging.

The American Congress of Rehabilitation Medicine and other authoritative sources have recognized that the term mild is misleading and does not reflect the potential severity of the injury and its impact on the person life.

Post-Concussion Syndrome (PCS)

Post-concussion syndrome (PCS) is a condition in which the symptoms of MTBI persist for weeks, months, or years after the injury. PCS is common -- affecting approximately 15-30% of people with MTBI.

Symptoms of PCS include: - Physical: Persistent headaches, dizziness, fatigue, sensitivity to light and noise, sleep disturbances. - Cognitive: Memory problems, difficulty concentrating, slowed thinking, word-finding difficulties. - Emotional: Irritability, mood swings, anxiety, depression, apathy. - Behavioral: Impulsivity, disinhibition, social withdrawal.

Risk factors for PCS include: - Female sex - Older age - Prior head injury - Prior psychiatric history (anxiety, depression) - Expectation of poor outcome - Psychosocial stressors - Severity of initial symptoms

PCS can significantly affect a person ability to work, maintain relationships, and enjoy life. It is a well-recognized medical condition, and the persistent symptoms are a well-established consequence of MTBI.

The Challenge of Proving MTBI

Proving MTBI in court is challenging for several reasons:

- Standard imaging may be normal: CT and standard MRI may appear normal in MTBI, even though the brain has been injured. This allows the defense to argue that there is no objective evidence of brain injury. - Symptoms may be subjective: Many MTBI symptoms (headache, dizziness, fatigue, memory problems) are subjective -- they cannot be objectively measured. This allows the defense to argue that the symptoms are exaggerated or fabricated. - The injury may not be immediately apparent: Symptoms may develop hours or days after the injury, allowing the defense to argue that the injury was not caused by the accident. - Pre-existing conditions: The defense may argue that the symptoms are caused by pre-existing conditions (prior head injury, psychiatric history, aging). - The person looks normal: People with MTBI often look perfectly normal on the outside, making it difficult for judges and juries to understand the severity of the injury.

To overcome these challenges, we use a combination of advanced neuroimaging, neuropsychological testing, lay witness testimony, and expert testimony to build a comprehensive picture of the injury and its impact.

Neuroimaging in MTBI Cases

While standard CT and MRI may appear normal in MTBI, advanced neuroimaging techniques can detect subtle brain injuries:

- Diffusion tensor imaging (DTI): A type of MRI that images the white matter tracts (axons) in the brain. DTI can detect diffuse axonal injury (DAI) -- microscopic damage to the axons -- which is a common injury in MTBI that is not visible on standard MRI. - Functional MRI (fMRI): Images brain activity by detecting changes in blood flow. fMRI can show abnormal brain function in people with MTBI, even when structural imaging is normal. - PET scan (positron emission tomography): Images brain metabolism. PET can show areas of reduced metabolism in people with MTBI. - SPECT scan (single photon emission computed tomography): Images brain blood flow. SPECT can show areas of reduced blood flow in people with MTBI. - A type of MRI that is highly sensitive to microbleeds (tiny hemorrhages) in the brain, which can occur in MTBI. - Magnetic resonance spectroscopy (MRS): Measures brain chemistry, which can be altered in MTBI.

These advanced imaging techniques provide objective evidence of brain injury that can support an MTBI claim. However, they are not available at all facilities and require specialized expertise to interpret. [Link to: /radiology-errors/mri-malpractice]

Neuropsychological Testing

Neuropsychological testing is the gold standard for documenting cognitive impairments in MTBI. Neuropsychological testing is a comprehensive assessment of cognitive function, including:

- Attention and concentration - Memory (short-term, long-term, working memory) - Executive function (planning, organization, judgment, impulse control) - Processing speed - Language (naming, fluency, comprehension) - Visuospatial function - Motor function - Mood and emotional function

Neuropsychological testing is objective and standardized -- the results are compared to normative data (based on age, education, and other factors) to determine whether the person cognitive function is impaired. This provides objective evidence of cognitive impairment, even when imaging appears normal.

Neuropsychological testing is typically performed by a neuropsychologist -- a psychologist with specialized training in brain-behavior relationships. The testing takes several hours to complete and involves a battery of standardized tests.

The results of neuropsychological testing can: - Document the presence and severity of cognitive impairment - Identify specific cognitive deficits (e.g., memory, attention, executive function) - Distinguish between brain injury and other causes (e.g., depression, anxiety, medication effects, malingering) - Provide a baseline for tracking recovery - Support the causal connection between the injury and the cognitive impairments

The Role of Lay Witness Testimony

In addition to expert testimony and objective evidence, lay witness testimony is critical in MTBI cases. Lay witnesses -- family members, friends, coworkers, and employers -- can describe the changes they have observed in the injured person since the injury:

- Changes in personality: Irritability, mood swings, impulsivity, social withdrawal. - Changes in cognitive function: Memory problems, difficulty concentrating, word-finding difficulties. - Changes in daily functioning: Difficulty with tasks that were previously easy, inability to work, need for reminders. - Changes in relationships: Strained relationships, social isolation. - Changes in physical function: Headaches, fatigue, sensitivity to light and noise.

Lay witness testimony is powerful because it comes from people who knew the injured person before and after the injury and can describe the changes firsthand. It provides a human perspective that complements the objective evidence from imaging and neuropsychological testing.

The Standard of Care for MTBI Diagnosis and Treatment

The standard of care for MTBI diagnosis and treatment includes:

- Prompt evaluation: Anyone who suffers a blow to the head should be evaluated promptly by a healthcare provider. - Neurological examination: Assessment of mental status, motor function, reflexes, sensation, and coordination. - CT scan: To rule out intracranial hemorrhage or other acute injuries, particularly in patients with loss of consciousness, severe headache, vomiting, or focal neurological deficits. [Link to: /radiology-errors/ct-scan-negligence] - Observation: Patients may be observed in the hospital or at home (with appropriate instructions) for signs of deterioration. - Neuropsychological testing: For patients with persistent symptoms, neuropsychological testing to document cognitive impairments. - Referral to a specialist: Neurologist, neuropsychologist, or rehabilitation specialist for patients with persistent symptoms. - Rest and gradual return to activity: Cognitive and physical rest initially, followed by a gradual return to activity as symptoms improve. - Medication management: For headaches, sleep disturbances, depression, and other symptoms. - Rehabilitation: Cognitive rehabilitation, physical therapy, occupational therapy, and speech therapy as needed. - Monitoring for persistent symptoms: Patients should be monitored for post-concussion syndrome and referred for additional treatment if symptoms persist.

Failure to meet any of these requirements may constitute negligence.

When MTBI Constitutes Malpractice or Negligence

An MTBI may constitute medical malpractice when a healthcare provider caused the injury (e.g., anesthesia error, surgical error) or failed to diagnose and treat the injury appropriately. It may constitute negligence when caused by a non-medical factor (e.g., motor vehicle accident, fall, construction accident).

Key considerations include: - Was the injury caused by negligence or malpractice? If caused by a motor vehicle accident, fall, or construction accident, the claim is based on general negligence. If caused by an anesthesia error, surgical error, or birth injury, the claim is based on medical malpractice. - Was the injury diagnosed and treated appropriately? If the healthcare provider failed to diagnose or treat the MTBI appropriately (e.g., failed to order a CT scan, failed to perform neuropsychological testing, failed to refer to a specialist), the failure may constitute malpractice. - Did the failure cause harm? The harm (worsened symptoms, delayed recovery, permanent impairment) must be causally connected to the failure.

Under New York law, expert testimony is required. A certificate of merit (CPLR 3012-a) must be filed with medical malpractice lawsuits.

Common Defense Arguments and How We Counter Them

Defense: The imaging is normal, so there is no brain injury.

Defense attorneys use several arguments in MTBI cases:

• Our Counter: Standard CT and MRI may appear normal in MTBI, even though the brain has been injured. We use advanced neuroimaging (DTI, fMRI, PET, SPECT, SWI) to detect subtle brain injuries that are not visible on standard imaging. We also use neuropsychological testing, which provides objective evidence of cognitive impairment even when imaging is normal. The absence of findings on standard imaging does not rule out brain injury.

Defense: The symptoms are subjective and cannot be objectively measured.

Our Counter: While some MTBI symptoms (headache, dizziness) are subjective, neuropsychological testing provides objective, standardized measures of cognitive function. We also use lay witness testimony from family members, friends, and coworkers who can describe the changes they have observed. The combination of objective testing and lay witness testimony provides a comprehensive picture of the injury and its impact.

Defense: The symptoms are caused by pre-existing conditions or psychological factors.

Our Counter: We use medical records and expert testimony to distinguish between pre-existing conditions and the MTBI. We also use the timing -- if the symptoms began after the injury, the causal connection is stronger. Neuropsychological testing can distinguish between brain injury and other causes (depression, anxiety, malingering).

Defense: The person is malingering or exaggerating symptoms.

Our Counter: Neuropsychological testing includes validity tests (e.g., symptom validity tests, performance validity tests) that can detect malingering or exaggeration. If the testing shows consistent, valid performance, it supports the genuineness of the symptoms. We also use lay witness testimony to corroborate the symptoms.

Defense: MTBI symptoms should have resolved within weeks.

Our Counter: While many concussions resolve within weeks, a significant percentage (15-30%) cause persistent symptoms (post-concussion syndrome) that last months or years. We use medical literature and expert testimony to establish that persistent symptoms are a well-recognized consequence of MTBI.
