What to Expect During Your Exam

Exam Overview

To document all current residuals of an in-service traumatic brain injury and establish their nature, severity, and impact on daily functioning for rating purposes under DC 8045. The examiner will assess cognitive, physical, and behavioral/emotional residuals across multiple standardized facets. A single evaluation is assigned using the highest level of impairment found in any one facet, with additional evaluations possible for separately ratable residuals.

What the examiner evaluates:

  • Cognitive facets: memory, attention, concentration, and executive functions
  • Behavioral/emotional facets: irritability, depression, anxiety, impaired judgment, social interaction deficits
  • Physical/neurological facets: headaches, dizziness/vertigo, motor and sensory deficits, visual disturbances, hearing loss, sleep disorders
  • Gait, coordination, and balance abnormalities
  • Speech and communication impairments
  • Autonomic and vegetative symptoms including bowel, bladder, and sexual dysfunction
  • Assistive device use and functional mobility
  • Muscle strength, tone, reflexes, and atrophy in all four extremities
  • Impact on occupational and social functioning
  • Current medications and treatments for TBI residuals
  • History of the TBI event, acute presentation, and subsequent course
  • Any neuropsychological test results, imaging, or diagnostic studies on file

Exam is typically conducted in person by a physician or psychologist contracted through VA or at a VAMC. For TBI, neuropsychological testing results in your file may be referenced. If the examiner has neuropsychological expertise, expect brief cognitive screening tasks during the interview. Bring a trusted family member or caregiver if permitted - their observations of your daily functioning are valuable and the examiner may note third-party input. In most states, you have the right to record the examination with advance notice.

Typical duration: 60-90 minutes

Cognitive Screening (Facet-Based Assessment)

Memory, attention, concentration, and executive function impairment. The examiner may administer brief tests such as the Mini-Mental State Exam (MMSE), Montreal Cognitive Assessment (MoCA), or review prior neuropsychological testing. The DBQ uses a 0-to-Total scale: 0 = no complaints, 1 = subjective complaints without objective findings, 2 = mild objective impairment with mild functional impact, 3 = moderate objective impairment with moderate functional impact, Total = severe objective impairment with severe functional impact.

What to expect:

The examiner will ask about memory problems, word-finding difficulty, ability to follow conversations, concentration during tasks, and your ability to plan or organize activities. They may ask you to recall a short list of words, do simple arithmetic, or draw a clock. Reference any formal neuropsychological testing you have had.

Key thresholds:

  • Level 0 - No complaints of impairment — Supports 0% rating for this facet
  • Level 1 - Subjective complaints only, no objective testing findings — Minimum documented impairment; supports low overall rating
  • Level 2 - Mild objective impairment on testing with mild functional impact — Supports moderate combined rating depending on other facets
  • Level 3 - Moderate objective impairment on testing with moderate functional impact — Can support 40% or higher combined rating
  • Total - Severe objective impairment on testing with severe functional impact — Supports 70% or 100% combined rating

Tips:

  • Bring copies of any neuropsychological test reports - these provide objective evidence critical to reaching Level 2, 3, or Total
  • Describe specific, concrete daily failures: 'I forgot my daughter's birthday,' not 'I have some memory problems'
  • Mention word-finding failures during the exam itself naturally - do not force errors but do not cover them up either
  • Describe how cognitive deficits affect your ability to work, manage finances, keep appointments, or maintain relationships

Pain considerations: Cognitive fatigue is a legitimate TBI residual - describe how sustained mental effort causes increased symptoms, headaches, or need to rest.

Behavioral and Emotional Facet Assessment

Irritability, depression, anxiety, impaired judgment, and social interaction deficits as direct TBI residuals. The DBQ uses the same 0-to-Total scale. Critically, the examiner must distinguish whether these symptoms are attributable to TBI residuals, a separate psychiatric condition, or a combination - as separate evaluations may be warranted.

What to expect:

The examiner will ask about mood changes since the TBI, anger or irritability that is out of character, social withdrawal, judgment errors (financial, safety, relationship), and anxiety. They may use brief depression or anxiety screening tools.

Key thresholds:

  • Level 0 - No behavioral or emotional symptoms — No contribution to rating from this facet
  • Level 1 - Mild, occasional symptoms, no functional impact — Minimal contribution; document baseline
  • Level 2 - Mild-moderate symptoms with some functional impact — May be determinative if highest facet
  • Level 3 - Moderate symptoms with moderate occupational and social impairment — Can drive 40% or higher rating
  • Total - Severe behavioral symptoms with severe social/occupational impairment — Can drive 70% or 100% rating

Tips:

  • Be specific about how your behavior has changed since the TBI compared to before
  • Describe incidents where impaired judgment caused real consequences: accidents, job loss, relationship breakdown
  • If family members have commented on your personality change, mention this directly
  • Note whether you have withdrawn from activities or relationships you previously enjoyed

Pain considerations: Emotional lability (unpredictable emotional reactions) and disinhibition are distinct TBI residuals - describe episodes accurately including their frequency and impact on family and work relationships.

Neurological Physical Examination - Motor Function

Muscle strength (graded 0/5 to 5/5), tone, coordination, reflexes, and presence of atrophy in upper and lower extremities bilaterally. The DBQ captures biceps, triceps, brachioradialis, wrist flexion/extension, grip, pinch, knee extension, and ankle dorsiflexion/plantar flexion reflexes and strength for both sides.

What to expect:

The examiner will test your grip strength, finger opposition, arm and leg push/pull resistance, and deep tendon reflexes. They will observe for tremor, spasticity, atrophy, or incoordination. Gait will be observed - note if you use an assistive device.

Key thresholds:

  • 5/5 strength - Full strength against resistance — Normal; no motor deficit documented
  • 4/5 strength - Reduced but functional against moderate resistance — Mild motor deficit
  • 3/5 strength - Movement against gravity only, no resistance — Moderate motor deficit; functional impairment expected
  • 2/5 or below - Movement with gravity eliminated or absent — Severe motor deficit; supports higher combined evaluation

Tips:

  • Demonstrate your actual functional ability - do not minimize weakness or disguise fatigue-related declines
  • If weakness worsens with repetitive use or fatigue, tell the examiner before testing begins
  • Report any limb that has muscle atrophy - the examiner should document circumference measurements
  • Note which limb is dominant when asked

Pain considerations: TBI-related motor deficits may worsen with physical or cognitive exertion - describe how your strength or coordination changes later in the day or after activity.

Headache Assessment

Frequency, duration, severity, and functional impact of post-traumatic headaches. Headaches are one of the most common TBI residuals and may be separately rated under DC 8100 (migraine) in addition to the TBI facet evaluation.

What to expect:

The examiner will ask about headache frequency (how many per month), duration, severity on a 0-10 scale, associated symptoms (nausea, light/sound sensitivity, visual disturbances), and impact on work and daily activity.

Key thresholds:

  • Infrequent, mild headaches — Lower rating contribution; document exact frequency and functional impact
  • Prostrating attacks 1+ per month — Supports 30% under DC 8100 if separately rated
  • Prostrating attacks more than once per month — Supports 50% under DC 8100 if separately rated
  • Characteristic prostrating attacks occurring very frequently and with severe economic inadaptability — 50% under DC 8100

Tips:

  • Log your headache frequency for at least 30 days before the exam using a diary or phone app
  • Use the word 'prostrating' accurately - it means the headache forces you to lie down, stop all activity, and rest
  • Describe light and sound sensitivity, nausea, and the inability to function during an episode
  • Note any triggers: light, noise, stress, exertion, screen time

Pain considerations: Describe your worst headache days in full detail. Note how long recovery takes after a severe episode and whether you lose work time or miss obligations.

Sleep Disturbance Assessment

Insomnia, hypersomnia, daytime sleep attacks, and sleep apnea as TBI residuals. The DBQ captures insomnia, hypersomnolence, sleep apnea (including device use and severity), and their functional impact.

What to expect:

The examiner will ask about your sleep patterns, use of CPAP or BiPAP, daytime fatigue, and whether sleep disturbance affects your daily function. They may ask about sleep study results.

Key thresholds:

  • Insomnia without daytime functional impact — Contributes minimally to facet evaluation
  • Insomnia or hypersomnia causing notable daytime impairment — Elevates behavioral/emotional or other facet rating
  • Sleep apnea requiring breathing assistance device — Separately ratable under DC 6847 at 50% - note if TBI-related

Tips:

  • Describe both the nighttime problem and the daytime consequences accurately
  • If you use a CPAP/BiPAP, bring documentation and note the diagnosis
  • Describe how fatigue from poor sleep compounds your cognitive symptoms - this is a recognized TBI mechanism

Pain considerations: Sleep deprivation significantly worsens cognitive and emotional TBI symptoms - describe the cumulative daily functional impact, not just the nighttime disruption.

Gait and Balance Assessment

Presence and severity of abnormal gait, ataxia, vertigo, and balance deficits as TBI neurological residuals. The examiner will observe your walk, may test tandem gait, and will note any assistive device use.

What to expect:

You will be observed walking, potentially in tandem (heel-to-toe), and the examiner may perform Romberg testing. They will note whether you use a cane, walker, or other device and how frequently.

Key thresholds:

  • Normal gait, no assistive device — No contribution from this facet
  • Mild imbalance or occasional dizziness — Low-level contribution; describe frequency and triggers
  • Requires cane or assistive device for ambulation — Elevates functional impairment level significantly; affects SMC eligibility
  • Requires walker or wheelchair — Significant functional impairment documented; consider SMC evaluation

Tips:

  • Use your assistive device during the exam if you normally use one - do not set it aside to appear more capable
  • Describe episodes of falls or near-falls and their frequency
  • Note whether dizziness is triggered by head movement, position changes, or exertion

Pain considerations: If your balance worsens with fatigue or cognitive load (e.g., walking while talking), describe this dual-task impairment explicitly.

Estimate

Rating Criteria Breakdown

100% One or more facets rated at the Total level: objective evide ...

One or more facets rated at the Total level: objective evidence on testing of severe impairment of memory, attention, concentration, or executive functions resulting in severe functional impairment; OR the veteran requires continuous observation and direction due to cognitive impairment; OR vegetative state or other severe neurological manifestation. This rating also triggers evaluation for Special Monthly Compensation (SMC) for aid and attendance, housebound status, or loss of use of an extremity.

Key Symptoms

  • Severe cognitive impairment documented on neuropsychological testing - unable to perform basic self-care, follow simple instructions, or manage daily activities
  • Requires constant supervision or assistance due to safety risks from cognitive deficits
  • Severe behavioral disturbance posing danger to self or others
  • Inability to communicate by speech (aphonia or severely impaired speech)
  • Complete or near-complete paralysis or loss of use of one or more extremities
  • Vegetative features or prolonged minimally conscious state
  • Feeding tube (PEG) or tracheostomy required
  • Severe autonomic dysfunction including bowel/bladder incontinence requiring absorbent material changed multiple times daily

CFR: Objective evidence on testing of severe impairment of memory, attention, concentration, or executive functions resulting in severe functional impairment. (Total level on the TBI facet scale.) Also consider SMC for aid and attendance and protection from hazards of the daily living environment due to cognitive impairment.

70% One or more facets rated at Level 3: objective evidence on t ...

One or more facets rated at Level 3: objective evidence on testing of moderate impairment in memory, attention, concentration, or executive functions resulting in moderate functional impairment; OR comparable moderate impairment in behavioral, emotional, or physical facets. Significant impact on occupational and social functioning expected.

Key Symptoms

  • Objective neuropsychological test findings showing moderate cognitive impairment
  • Moderate functional impairment affecting ability to maintain employment or manage daily responsibilities
  • Moderate depression, anxiety, or PTSD symptoms with documented occupational and social impact
  • Moderate to severe behavioral changes (significant irritability, impaired judgment, social withdrawal)
  • Moderate motor deficits (3/5 strength in one or more muscle groups, ataxia, moderate gait abnormality)
  • Frequent prostrating headaches
  • Moderate speech impairment affecting communication
  • Sleep disorders causing significant daytime impairment

CFR: Objective evidence on testing of moderate impairment of memory, attention, concentration, or executive functions resulting in moderate functional impairment. (Level 3 on the TBI facet scale.)

40% One or more facets rated at Level 2: objective evidence on t ...

One or more facets rated at Level 2: objective evidence on testing of mild impairment in memory, attention, concentration, or executive functions resulting in mild functional impairment; OR comparable mild objective impairment in behavioral, emotional, or physical facets. The highest single facet level drives the overall rating.

Key Symptoms

  • Objective findings on neuropsychological or cognitive screening tests showing mild impairment
  • Mild but documented functional impairment in work or daily activities
  • Mild depression, anxiety, or irritability with observable functional impact
  • Headaches with moderate frequency or functional disruption not yet meeting the prostrating threshold for higher rating
  • Mild motor deficits on examination (e.g., 4/5 strength, mild coordination deficits)
  • Mild speech abnormalities or word-finding deficits observed during the exam

CFR: Objective evidence on testing of mild impairment of memory, attention, concentration, or executive functions resulting in mild functional impairment. (Level 2 on the TBI facet scale.)

10% One or more facets rated at Level 1: subjective complaints o ...

One or more facets rated at Level 1: subjective complaints of mild cognitive, behavioral, or physical impairment without objective evidence on testing. Functional impact is minimal. This is the entry-level compensable rating for documented TBI residual symptoms.

Key Symptoms

  • Mild memory complaints such as difficulty finding words, forgetting names of new acquaintances, or misplacing items
  • Mild irritability or mood changes without objective impairment
  • Occasional headaches not meeting the prostrating threshold
  • Mild sleep disturbance without daytime functional impairment
  • Subjective dizziness without balance deficit on examination

CFR: A complaint of mild loss of memory (such as having difficulty following a conversation, recalling recent conversations, remembering names of new acquaintances, or finding words, or often misplacing items), attention, concentration, or executive functions, but without objective evidence on testing.

0% A TBI diagnosis is established with service connection, but ...

A TBI diagnosis is established with service connection, but no current ratable residuals are identified. All facets of the TBI evaluation table are rated at Level 0. The 0% rating preserves the service connection and the door open for future increases if residuals develop or worsen.

Key Symptoms

  • No subjective complaints of cognitive impairment
  • No behavioral or emotional changes attributable to TBI
  • No physical neurological deficits on examination
  • No headaches, sleep disturbance, or autonomic symptoms

CFR: Grant SC for TBI under 38 CFR 4.124a, DC 8045, 0 percent when the examiner marks all facets as normal and post-service records show no disabling signs or symptoms. A 0% rating still establishes SC for future claims.

How to Describe Your Symptoms

Memory and Cognitive Deficits

How to describe:

Be specific, concrete, and anchored to daily life failures. Avoid vague generalities. Describe the type of memory problem (working memory, short-term, prospective), the frequency of failures, the consequences, and any compensatory strategies you have adopted (e.g., using phone reminders because you cannot remember appointments without them).

Worst-day example:

“On a bad day, I cannot follow a conversation with my spouse without losing track of what we were talking about mid-sentence. I will walk into a room and have no idea why. I miss appointments even when I wrote them down. I cannot read more than a paragraph before I have to start over. My wife handles all our finances now because I made several errors that cost us money. I forget whether I took my medications even minutes after taking them.”

What the examiner listens for:

Specific behavioral examples of memory failure, evidence that the problem causes real functional consequences, use of compensatory strategies suggesting awareness of deficit, impact on employment and independent living, and any neuropsychological test results in the file that corroborate the self-report.

Understatements to avoid:

Saying 'my memory is a little off' or 'I forget things sometimes' - everyone forgets things sometimes. The examiner needs to understand that your forgetting is frequent, disruptive, and qualitatively different from normal age-related forgetting.

Headaches

How to describe:

Report frequency in episodes per month, typical duration of each episode, peak severity (0-10), and the functional impact - specifically whether they force you to stop activity and lie down (prostrating). Describe associated symptoms such as light and sound sensitivity, nausea, visual aura, and how long recovery takes after a severe episode.

Worst-day example:

“My worst headaches come on suddenly, usually triggered by noise, bright light, or stress. The pain reaches an 8 or 9 out of 10. I have to go into a dark, quiet room and lie completely still for 3 to 4 hours. I cannot work, drive, or care for my children during an episode. This happens at least 6 times per month. The day after a severe headache I am still foggy and fatigued.”

What the examiner listens for:

The word 'prostrating,' frequency per month, duration, functional incapacitation during episodes, triggers, and whether the veteran has sought medical treatment or adjusts their schedule around headache risk.

Understatements to avoid:

Describing headaches only as 'pretty bad' without detailing how they completely stop your activity. If you push through a headache and go to work anyway, you may be underreporting the actual severity. The standard is the level of impairment, not your stoicism.

Behavioral and Emotional Changes

How to describe:

Describe how your personality, temperament, or emotional responses have changed since the TBI event compared to before. Use before-and-after comparisons. Give specific examples of behavioral incidents. Include family or employer observations where relevant. Distinguish between reactive anger (triggered by something specific) and organic irritability (out of proportion, seemingly unprovoked).

Worst-day example:

“Before my injury I was patient and calm. Now I lose my temper over minor things - my children dropping something, a small delay in traffic. I have thrown objects and said things I deeply regret. My wife says I am 'a different person.' I have no filter now - I say things in social situations that I know are inappropriate but I cannot stop myself. I have stopped socializing because I embarrass myself and my family. I have been passed over for promotion twice because my supervisor said I have an attitude problem.”

What the examiner listens for:

Concrete behavioral incidents, corroboration from family or treatment records, evidence that the change is organic to the TBI rather than purely psychological, and functional impact on employment, family stability, and social relationships.

Understatements to avoid:

Minimizing behavioral changes by saying 'I just have a shorter fuse now.' The examiner needs to understand the severity, frequency, and real-world consequences of these changes.

Physical Neurological Symptoms - Dizziness, Balance, and Coordination

How to describe:

Describe the type of dizziness (room spinning versus lightheadedness versus off-balance feeling), its triggers (head movement, position change, activity, fatigue), frequency, duration, and functional impact. Note any falls, near-falls, or activity restrictions due to balance problems.

Worst-day example:

“When I turn my head quickly, the room spins. I have to grab a wall or sit down. This happens daily. I have fallen twice in the past six months - once on the stairs. I no longer drive on the highway because I get disoriented and dizzy when checking my blind spot. I cannot be on ladders or scaffolding. I need my cane when I am tired because my balance is much worse later in the day.”

What the examiner listens for:

Falls, near-falls, activity restrictions, use of assistive devices, worsening with fatigue or dual-tasking, and whether the veteran has been evaluated for vestibular disorder or cervicogenic dizziness.

Understatements to avoid:

Saying 'I feel a little dizzy sometimes' without describing the functional limitation. Leaving out fall history is a common omission that affects the documented severity.

Sleep Disturbance

How to describe:

Describe the specific sleep problem (difficulty falling asleep, staying asleep, early awakening, nightmares, non-restorative sleep, excessive daytime sleepiness), its frequency, and its daytime functional consequences including fatigue, cognitive worsening, and impact on daily obligations.

Worst-day example:

“I average 4 to 5 hours of broken sleep per night. I wake up 3 to 4 times, usually from nightmares or pain. Even on nights when I do sleep more, I wake up feeling unrefreshed. By early afternoon I am so fatigued I cannot focus or function. I have fallen asleep at my desk at work twice this month. My cognitive problems are significantly worse on days after poor sleep. On my worst days I cannot leave the house because I am too impaired to drive safely.”

What the examiner listens for:

Objective sleep studies (if available), daytime functional impact, how sleep deprivation compounds cognitive TBI symptoms, CPAP use and compliance, and whether nightmares are PTSD-related versus non-PTSD TBI-related - important for separate rater consideration.

Understatements to avoid:

Saying 'I do not sleep great' without quantifying the problem or describing its functional consequences. Do not omit the compounding effect of poor sleep on your cognitive TBI symptoms.

Motor Deficits, Weakness, and Coordination

How to describe:

Describe which limbs are affected, what tasks you can no longer do or do with difficulty, and how weakness or coordination problems have changed your daily life. If deficits are asymmetric, specify which side and whether it affects your dominant hand.

Worst-day example:

“My right hand is significantly weaker than before my injury. I drop items without warning - cups, tools, my phone. I cannot open jars or turn a wrench with any force. My handwriting is illegible now. My wife cuts food for me. On days when I am fatigued, my hand barely works and I have dropped hot items causing minor burns. I can no longer do the manual labor my job requires.”

What the examiner listens for:

Specific grip and pinch failure examples, dominant hand involvement, impact on employment and self-care, whether atrophy is visible or measurable, and whether deficits are consistent with an upper motor neuron versus lower motor neuron pattern from the TBI.

Understatements to avoid:

Demonstrating full strength during the examination when you actually have functional weakness - push to the point of your actual limit, do not stop early to appear compliant.

Your Rights During a C&P Exam

  • You have the right to request and review your complete VA claims file (c-file) at any time using a FOIA request or through your VSO.
  • You have the right to submit additional evidence at any stage of the claims process, including after the C&P examination, before a rating decision is issued.
  • In most U.S. states, you have the right to record your C&P examination. Check current VA policy and your state's recording consent laws, and provide advance written notice to the examination scheduling office.
  • You have the right to be accompanied by a support person, VSO representative, or caregiver during the examination.
  • You have the right to challenge an inadequate, insufficient, or inaccurate C&P examination by requesting a new examination, submitting a private IMO, or filing a Notice of Disagreement.
  • You have the right to multiple separate evaluations for TBI residuals that are separately ratable under different diagnostic codes - this is not pyramiding under M21-1 guidance when symptoms are distinct.
  • You have the right to be evaluated for Special Monthly Compensation (SMC) when TBI residuals include loss of use of an extremity, need for aid and attendance, housebound status, or sensory impairments.
  • You have the right to a reasoned written explanation of how the rating was determined, including how each facet of the TBI evaluation table was rated.
  • You have the right to a fully favorable benefit of the doubt when evidence is in approximate balance - per 38 U.S.C. 5107(b), doubt is resolved in the veteran's favor.
  • You have the right to request a rating decision review through Supplemental Claim, Higher-Level Review, or Board of Veterans Appeals if you disagree with the decision.
  • A 0% rating for TBI still establishes service connection and can be increased later if residuals develop, worsen, or are newly documented - this is a valuable preserved right.
  • Per M21-1, a medical classification of TBI severity at the time of the acute trauma (mild, moderate, severe) has no bearing on VA compensation evaluation and cannot be used to limit your rating.
