What to Expect During Your Exam

Exam Overview

To document the current nature, severity, and functional impact of your service-connected malignant brain tumor under 38 CFR 4.124a, DC 8002. The examiner will assess whether active disease is present or whether treatment has concluded, and will evaluate all residual neurological deficits for rating purposes. Under DC 8002, active malignant brain disease is rated 100%. After treatment cessation, a mandatory re-examination is scheduled two years later, at which point residuals are rated individually.

What the examiner evaluates:

  • Current status of malignant brain tumor (active vs. in remission/post-treatment)
  • Treatment history: surgery, radiation therapy, antineoplastic chemotherapy, and dates
  • Neurological deficits and residuals: motor weakness, paralysis, sensory loss, incoordination
  • Cognitive and speech impairments: memory loss, aphasia, inability to communicate by speech
  • Seizure activity and frequency
  • Gait abnormalities and need for assistive devices (cane, walker, wheelchair, braces, crutches)
  • Bladder and bowel dysfunction (neurogenic bladder/bowel secondary to tumor or treatment)
  • Dysphagia and swallowing dysfunction
  • Sleep disturbances including insomnia, hypersomnia, sleep apnea
  • Weight loss and nutritional status
  • Tumor type (benign vs. malignant classification on DBQ)
  • Muscle strength and deep tendon reflexes in all extremities
  • Presence of muscle atrophy in any extremity
  • Impact of the condition on daily activities, employment, and social functioning
  • Any additional diagnoses attributable to the brain tumor or its treatment

The exam will typically include a face-to-face neurological examination and detailed medical history interview. Bring a trusted support person if cognitive or communication difficulties make self-reporting difficult. In most states you have the right to record the exam. If you use a wheelchair, walker, cane, or braces, bring them to the exam and use them as you normally would. If you experience severe fatigue on exam day, inform the examiner that this represents a typical bad day for your condition.

Typical duration: 60-90 minutes

Muscle Strength Testing (Manual Muscle Testing - MMT Scale 0-5)

Motor function in upper and lower extremities bilaterally. Examiner will test elbow flexion/extension, wrist flexion/extension, grip strength, pinch strength, knee extension, and ankle dorsiflexion/plantar flexion on both sides. Deep tendon reflexes (biceps, brachioradialis, triceps, knee, ankle) will also be tested bilaterally.

What to expect:

You will be asked to push or pull against resistance. The examiner rates each muscle group on a 0-5 scale (0=no contraction, 5=full strength against resistance). Reflexes are tested with a reflex hammer and graded as absent, diminished, normal, or hyperactive.

Key thresholds:

  • MMT 0-1: No or flicker of contraction — Consistent with complete or near-complete paralysis; supports maximum residual ratings
  • MMT 2-3: Movement with gravity eliminated or against gravity only — Consistent with severe to moderate paralysis of the affected extremity
  • MMT 4: Movement against some resistance — Consistent with mild to moderate weakness; rated under appropriate paralysis DC
  • Hyperreflexia/clonus — Indicates upper motor neuron lesion consistent with brain tumor involvement

Tips:

  • Demonstrate your actual functional ability - do not overperform because you are trying to be cooperative; show what you can genuinely do
  • If strength varies throughout the day due to fatigue (a DeLuca factor), tell the examiner: 'My strength is weaker later in the day and after exertion'
  • Report any numbness, tingling, or sensory changes in the same extremities being tested
  • If one side is more affected than the other, clearly identify the weaker side and connect it to your tumor location

Pain considerations: If you experience headaches or pain during any part of the examination, report this immediately. Note the character (pressure, throbbing), location, radiation, and severity (0-10 scale) of any headache pain triggered or worsened by the exam.

Gait and Coordination Assessment

The examiner will observe your walking pattern, balance, ability to perform heel-to-toe walking, Romberg test (balance with eyes closed), and finger-to-nose or finger-to-finger coordination testing. Ataxia, spasticity, hemiplegia, or other gait abnormalities will be noted and described.

What to expect:

You will be asked to walk across the room, turn, and return. The examiner watches for unsteadiness, asymmetry, foot drop, spasticity, or use of compensatory movements. If you require an assistive device, use it as you normally would.

Key thresholds:

  • Inability to ambulate without a wheelchair — Supports Special Monthly Compensation (SMC) consideration and highest residual ratings
  • Requires cane, crutches, or walker for ambulation — Documented assistive device use supports moderate-to-severe functional impairment ratings
  • Ataxia or significant incoordination affecting ADLs — Supports rating under relevant paralysis or cerebellar DCs as residuals

Tips:

  • Use your actual assistive devices during the exam - do not try to walk without them to appear 'better'
  • Tell the examiner if your balance is worse on certain days, in certain lighting, or when fatigued
  • Report any falls you have had due to balance or coordination problems - frequency and circumstances matter
  • If you have multiple conditions contributing to gait abnormality, the examiner is required to attribute each component to the appropriate diagnosis

Pain considerations: Report any dizziness, vertigo, or headache worsening during ambulation or coordination testing.

Cognitive and Speech Assessment

Evaluates orientation, memory (short and long term), executive function, language, and speech. The examiner will note whether speech is intelligible, whether aphasia is present, and whether there is constant inability to communicate by speech.

What to expect:

The examiner may ask orientation questions (date, place, name), memory tasks, simple calculations, and observe the clarity and coherence of your speech. Speech abnormalities will be described in the DBQ.

Key thresholds:

  • Constant inability to communicate by speech — Maps to highest-level communication impairment on DBQ; supports SMC consideration
  • Speech not intelligible or individual is aphonic — Directly captured on DBQ field for severe speech impairment
  • Significant memory or cognitive deficits affecting daily function — May support separate TBI or mental health rating or higher combined rating

Tips:

  • If you have word-finding difficulty, tell the examiner: 'I struggle to find the right words, especially when fatigued or under stress'
  • If a family member or caregiver can provide a lay statement about observed cognitive changes, bring it to the exam
  • Describe how cognitive deficits affect your work, finances, driving, medication management, and social interactions
  • Do not minimize memory problems - be specific about what you forget and how often

Pain considerations: Report headaches that worsen with cognitive effort or conversation, as these represent a real functional limitation.

Pulmonary Function Tests (Spirometry: FVC, FEV1, FEV1/FVC)

Respiratory muscle function, relevant if the tumor or treatment has affected respiratory control or if dysphagia/aspiration has led to pulmonary complications. The DBQ specifically captures FEV1, FVC, FEV1/FVC ratio, and test dates.

What to expect:

You will be asked to breathe into a spirometer device. This is only conducted if respiratory impairment is clinically indicated based on your symptoms.

Key thresholds:

  • FEV1 < 40% predicted — Consistent with severe obstructive or restrictive respiratory impairment
  • Sleep apnea requiring CPAP/BIPAP — Captured on DBQ; rates as separate disability if neurologically caused

Tips:

  • Report any shortness of breath, choking episodes, aspiration, or sleep apnea to the examiner
  • If you use a CPAP or BiPAP machine, bring documentation or inform the examiner
  • Report daytime hypersomnolence, sleep attacks, or chronic fatigue to ensure these are documented

Pain considerations: Report chest pain or headache with exertion or deep breathing.

Bladder and Bowel Function Assessment

Neurogenic bladder and bowel dysfunction secondary to the brain tumor or its treatment. The DBQ captures urinary leakage, voiding frequency, hesitancy, slow stream, urinary retention requiring catheterization, UTI frequency, bowel incontinence, constipation, and use of absorbent materials.

What to expect:

The examiner will ask detailed questions about urinary and bowel symptoms. No invasive testing is typically performed at the C&P exam unless specifically ordered. You will be asked about frequency, urgency, leakage, assistive management, and hospitalizations.

Key thresholds:

  • Urinary retention requiring intermittent or continuous catheterization — Highest urinary dysfunction level on DBQ; supports 60-80% rating for neurogenic bladder
  • Bowel incontinence requiring absorbent material changed more than 4 times/day — Highest bowel incontinence severity level on DBQ
  • Recurrent UTIs secondary to obstruction — Captured separately; supports higher combined ratings

Tips:

  • Track your urinary and bowel symptoms for at least two weeks before the exam - note frequency, accidents, and catheter use
  • Report all urinary tract infections you have had and how many hospitalizations resulted
  • If you use absorbent pads or diapers, note how many you change per day on your worst days
  • Do not underreport bowel incontinence out of embarrassment - this directly affects your rating

Pain considerations: Report any pelvic, abdominal, or bladder pain associated with urinary or bowel dysfunction.

Estimate

Rating Criteria Breakdown

100% Active malignant brain tumor (DC 8002). The 100% rating appl ...

Active malignant brain tumor (DC 8002). The 100% rating applies while the malignancy is active and during the six-month period following cessation of surgical, radiation, antineoplastic chemotherapy, or other therapeutic procedure. Per M21-1 guidance, re-examination is scheduled two years after treatment cessation for SC brain malignancy under DC 8002.

Key Symptoms

  • Active malignant brain tumor with or without treatment
  • Currently undergoing surgery, radiation, or chemotherapy
  • Within six months of treatment cessation
  • Any level of neurological impairment during active disease phase

CFR: Under 38 CFR 4.124a, DC 8002, malignant brain tumors are rated 100% as active disease. The 100% rating continues for 6 months post-treatment. After that period with no local recurrence or metastases, rating is based on residuals. M21-1 specifies re-examination at two years post-treatment cessation for DC 8002.

100% Post-treatment residuals rated at 100% if neurological defic ...

Post-treatment residuals rated at 100% if neurological deficits are of sufficient combined severity. After the mandatory 6-month post-treatment period, residuals are individually rated under the appropriate diagnostic codes (e.g., hemiplegia, aphasia, seizures, neurogenic bladder). Combined ratings can reach 100% if deficits are severe enough.

Key Symptoms

  • Complete or near-complete hemiplegia (one side of body)
  • Constant inability to communicate by speech (aphasia)
  • Severe seizure disorder with very frequent episodes
  • Requirement for continuous nursing care or aid and attendance
  • Inability to ambulate without wheelchair
  • Severe neurogenic bladder requiring continuous catheterization

CFR: Post-treatment residuals are rated under 38 CFR 4.124a using applicable DCs for paralysis (e.g., DC 8103 for hemiplegia), communication disorders, and seizure disorders. SMC under 38 CFR 3.350 may apply if the veteran requires aid and attendance or has loss of use of extremities.

60% Post-treatment residuals with moderate-to-severe neurologica ...

Post-treatment residuals with moderate-to-severe neurological deficits. This level typically reflects significant but incomplete motor deficits, moderate seizure activity, moderate cognitive impairment, or significant neurogenic bladder/bowel dysfunction not reaching 100% combined.

Key Symptoms

  • Moderate hemiparesis or monoplegia in a major extremity
  • Frequent seizures (more than once monthly) not fully controlled by medication
  • Moderate aphasia with significant communication limitations
  • Neurogenic bladder with recurrent UTIs or requiring catheterization
  • Significant gait ataxia requiring assistive device use
  • Moderate cognitive impairment affecting work and daily activities

CFR: Residuals rated under 38 CFR 4.124a DCs as appropriate (e.g., DC 8511 for incomplete paralysis of an extremity, seizure DCs, communication disorder DCs). Combined rating calculation applies when multiple residual conditions are rated separately.

10% Minimum rating for residuals following active brain cancer. ...

Minimum rating for residuals following active brain cancer. After the 6-month post-treatment period with no recurrence and no significant ongoing deficits, a minimum 10% rating applies under the analogous principle for residuals of brain disease (per DC 8020 notes regarding minimum 10% for residuals).

Key Symptoms

  • Mild residual headaches
  • Mild fatigue beyond pre-illness baseline
  • Mild cognitive changes such as occasional word-finding difficulty
  • Mild sensory changes in an extremity
  • Mild sleep disturbance attributable to the condition or treatment

CFR: 38 CFR 4.124a notes for brain disease indicate that residuals should be rated at a minimum of 10% even when deficits are mild. Veterans should not receive a 0% rating for residuals of a treated malignant brain tumor.

How to Describe Your Symptoms

Tumor Status and Treatment History

How to describe:

Clearly state whether your tumor is currently active, whether you are in treatment, or whether treatment has ended and the date it ended. Specify all treatments received: craniotomy, stereotactic radiosurgery, whole-brain radiation, chemotherapy (drug names and cycles), and any watchful waiting status. Be precise about dates - the 6-month post-treatment 100% rating period depends on documented treatment dates.

Worst-day example:

“On my worst days following chemotherapy, I cannot get out of bed due to extreme nausea, fatigue, and confusion. I require my family to manage all my medications and personal care. Even on better days, I am exhausted by mid-morning and must rest for several hours.”

What the examiner listens for:

Clear timeline of diagnosis, treatment types, treatment dates, current status (active/remission/watchful waiting), and whether the veteran is within the 6-month post-treatment window warranting continued 100% rating.

Understatements to avoid:

Do not say 'I finished treatment and I'm doing okay' without fully describing ongoing residual symptoms. The examiner needs to know about every persistent deficit even if you are managing them.

Motor Weakness and Paralysis

How to describe:

Describe which side of your body is weaker, which specific movements are most affected, and how the weakness limits your daily activities. Use concrete examples: 'I drop objects from my right hand without warning,' 'I cannot grip a pen to write,' 'I cannot lift my left leg high enough to climb stairs safely.' Connect weakness to your tumor's location (e.g., left frontal tumor causing right-sided weakness).

Worst-day example:

“On my worst days, my right arm is so weak I cannot lift a cup of coffee or button my shirt. My right leg drags when I walk and I have to concentrate intensely to avoid falling. I need my spouse to help me dress and sometimes to help me walk to the bathroom.”

What the examiner listens for:

Laterality of weakness, specific muscle groups affected, functional limitations in ADLs, whether weakness is constant or fluctuating, and whether assistive devices are needed for ambulation.

Understatements to avoid:

Do not say 'I have some weakness' without specifying which limbs, what activities are impossible or very difficult, and whether weakness has worsened since diagnosis or treatment.

Seizures

How to describe:

Describe the type of seizures (generalized tonic-clonic, focal, absence), frequency (how many per month on average and on the worst months), duration, warning signs (aura), post-ictal period (confusion, fatigue, weakness after seizure), and impact on your ability to drive, work, and live safely. Report all current anti-seizure medications and whether they fully control your seizures.

Worst-day example:

“During my worst month, I had four grand mal seizures. Each one left me confused and exhausted for the rest of the day. I have not been able to drive for three years because of unpredictable seizure activity. I cannot work at heights or near machinery and cannot be left alone with my children during bad periods.”

What the examiner listens for:

Seizure type, frequency including worst months, medication names and whether they control seizures fully, functional impact including driving restrictions, employment limitations, and safety concerns.

Understatements to avoid:

Do not average out your seizures over a long period - report your worst monthly frequency. Do not omit post-ictal symptoms, which can last hours to days and are separately disabling.

Cognitive and Memory Impairment

How to describe:

Describe specific memory failures (e.g., forgetting mid-sentence what you were saying, forgetting appointments, repeating questions you already asked), executive function problems (difficulty planning, organizing, initiating tasks), attention deficits, and processing speed. Quantify how this affects your ability to work, manage finances, drive, and engage socially.

Worst-day example:

“On my worst days, I cannot hold a simple conversation because I lose my train of thought every few sentences. I have called 911 by accident because I could not remember why I picked up the phone. My wife manages all our finances because I cannot process numbers reliably. I have had to stop driving because I get disoriented even in familiar areas.”

What the examiner listens for:

Specific and concrete examples of memory failures, executive dysfunction, and how cognitive deficits have changed the veteran's ability to work and live independently. The examiner will note these for potential TBI residual rating and the functional impairment section of the DBQ.

Understatements to avoid:

Do not say 'I'm a little forgetful' - be specific about the frequency and severity of cognitive failures and their real-world consequences.

Speech and Communication Deficits

How to describe:

Describe whether you have difficulty finding words (anomia), forming sentences (expressive aphasia), understanding spoken language (receptive aphasia), or producing clear speech sounds (dysarthria). Note whether these problems are constant or intermittent and how they affect your ability to communicate with family, healthcare providers, and employers.

Worst-day example:

“On my worst days, I cannot complete a sentence without losing the word I need. My speech comes out slurred and people ask me to repeat myself constantly. My family has learned to speak slowly and give me extra time to respond. I cannot use the telephone effectively because I cannot process rapid speech.”

What the examiner listens for:

Whether the veteran can communicate by speech at all, whether speech is intelligible, whether communication deficits are constant vs. fluctuating, and specific DBQ-relevant categories including aphonia, expressive aphasia, and paralysis of soft palate.

Understatements to avoid:

Do not speak more fluently during the exam than you typically do - if the exam setting reduces your anxiety and temporarily improves your speech, tell the examiner that your speech is much worse at home, when fatigued, or under stress.

Fatigue and Functional Decline

How to describe:

Describe the severity of fatigue beyond normal tiredness - the kind that prevents you from completing basic tasks. Quantify how many hours per day you can be functional, how many hours you must rest, and what triggers worsening (activity, cognitive effort, heat, stress). This is a critical DeLuca factor for neurological conditions.

Worst-day example:

“On my worst days, I am exhausted after showering and getting dressed. I must rest for two hours after any physical activity of more than ten minutes. I cannot sustain any productive activity for more than one hour before my symptoms - weakness, confusion, and headache - become too severe to continue. By noon I am typically confined to bed or the couch.”

What the examiner listens for:

How fatigue limits the veteran's functional capacity across the day, whether fatigue is worsened by activity (reflecting the DeLuca factor of repetitive use decline), and how fatigue interacts with other neurological symptoms.

Understatements to avoid:

Do not say 'I get tired.' Describe how fatigue is qualitatively different from normal tiredness, how it comes on, what it prevents you from doing, and how long recovery takes.

Bladder and Bowel Dysfunction

How to describe:

Report urinary urgency, frequency, leakage, hesitancy, slow stream, or retention. Report bowel incontinence, constipation, or mucorrhea. Specify how many times per day you urinate, how many accidents you have per week, whether you use catheters, and how many absorbent pads you use and change per day. Report all UTIs over the past year and any hospitalizations.

Worst-day example:

“On my worst days I urinate every 30 to 45 minutes and still have accidents before I can reach the bathroom. I use adult absorbent briefs and change them four to five times per day. I have had three urinary tract infections requiring hospitalization this year.”

What the examiner listens for:

Specific frequency of bladder and bowel accidents, need for catheterization, use of absorbent materials and frequency of change, UTI history and hospitalizations. These directly determine ratings for neurogenic bladder and bowel under the DBQ.

Understatements to avoid:

Do not downplay incontinence out of embarrassment. The examiner needs exact numbers - accidents per day, pad changes per day, catheter use frequency - to fill in the correct DBQ fields.

Headaches and Pain

How to describe:

Describe the location, character (pressure, throbbing, stabbing), severity (0-10 scale), frequency, duration, and triggers of your headaches. Describe how headaches limit your activity. Note whether headaches are worse in the morning (elevated intracranial pressure pattern), with exertion, or with cognitive effort.

Worst-day example:

“On my worst days, my headache is an 8 or 9 out of 10, located behind my right eye and radiating to my right temple. It forces me into a dark, quiet room for four to six hours and is not fully relieved by any medication I have been given. These severe headaches occur three to five times per week.”

What the examiner listens for:

Frequency and severity of headaches, functional impact (bed rest, missed work), medication use and effectiveness, and whether the headache pattern is consistent with intracranial pathology from the tumor or treatment.

Understatements to avoid:

Do not say 'I get headaches sometimes.' Give specific frequency, duration, and severity numbers. Report how many days per month headaches prevent you from functioning normally.
