Understanding Neurological Conditions and Their Documentation Requirements 

Neurological disorders include a wide array of conditions affecting the central nervous system (brain/spinal cord) and peripheral nervous system. These disorders, often resulting from traumatic injuries, exposure to hazardous conditions, infectious processes, or long-term military-related stressors, require specialized and thorough medical documentation to support your VA claim. 

According to the VA’s Fiscal Year 2024 Annual Benefits Report, neurological disorders including migraines, epilepsy, neuropathy, and TBI, rank among the top five most common service-connected disabilities for new compensation recipients. 

Common Neurological Conditions & How to Document Them 

Traumatic Brain Injury (TBI) Residuals 

Includes cognitive deficits, headaches, dizziness, fatigue, sleep disturbances, irritability, and personality changes. 

Medical Evidence Needed: 

• Neurologist evaluation documenting initial injury, current symptoms, and chronic implications. 

• Neuropsychological test results clearly documenting cognitive impairment levels. 

• Detailed descriptions of emotional/behavioral changes by healthcare professionals. 

• Imaging studies (MRI or CT scans) documenting brain structural changes when present. 

• Documentation of headaches, frequency, severity, and treatment effectiveness. 

Migraines and Other Chronic Headache Disorders 

Includes migraine headaches (with/without aura), cluster headaches, tension headaches, and post-traumatic headaches. 

Medical Evidence Needed: 

• Neurologist diagnosis with specific headache type clearly identified. 

• Headache diary or logs documenting precise frequency, duration, severity (pain scale 1-10), and specific symptoms (nausea, sensitivity to light/sound). 

• Clear documentation of episodes that are “prostrating” (incapacitating), which necessitate bed rest or cessation of activity. 

• Documentation of medication trials, dosages, effectiveness, and adverse effects. 

Epilepsy and Seizure Disorders 

Includes seizure types such as generalized tonic-clonic (grand mal), absence (petit mal), focal, and psychomotor seizures. 

Medical Evidence Needed: 

• Neurologist diagnosis specifying seizure type clearly. 

• EEG (electroencephalogram) reports demonstrating seizure activity or abnormal brain function. 

• Brain imaging studies (MRI/CT) results to assess structural brain abnormalities. 

• Seizure logs clearly documenting frequency, type, duration, recovery time, and injuries from seizure events. 

• Witness statements describing observed seizure events. 

• Medication regimen records: accurate dosage, blood levels, and documented efficacy and side effects. 

• Documentation of driving restrictions or occupational limitations due to seizures. 

Parkinson’s Disease and Related Conditions 

Includes typical Parkinson’s Disease and Parkinsonian syndromes linked to Agent Orange or other exposures. 

Medical Evidence Needed: 

• Specialist neurologist documentation confirming Parkinsonian diagnosis. 

• Detailed documentation of cardinal symptoms: resting tremor, rigidity, slow movements (bradykinesia), balance instability. 

• Unified Parkinson’s Disease Rating Scale (UPDRS) and Hoehn & Yahr staging documentation. 

• Assessment of medication effectiveness (e.g., levodopa, dopamine agonists) and documented side effects or fluctuations in symptom control. 

• Complete and detailed documentation of mobility limitation, assistive device use, and functional limitations in daily living. 

Multiple Sclerosis (MS) 

Includes progressive, relapsing-remitting, secondary-progressive, and primary-progressive forms of MS. 

Medical Evidence Needed: 

• Neurologist diagnosis, clearly documented with public health criteria and imaging (MRI) confirming demyelinating lesions. 

• Records of episodes (relapses/exacerbations): frequency, duration, severity of symptoms. 

• Expanded Disability Status Scale (EDSS) documentation, if available. 

• Thorough documentation of specific MS symptoms: muscular weakness, sensory disturbances, dizziness, visual impairments, bladder/bowel dysfunction. 

• Treatment records clearly documenting disease-modifying therapy, effectiveness, adverse events, and compliance. 

• Documentation supporting impact on occupational or daily functioning and the necessity of assistive devices (canes, wheelchairs, etc.).

Peripheral Neuropathy 

Includes diabetic neuropathy, toxic exposure neuropathy, entrapment neuropathy (e.g., carpal tunnel), or nerve injury from trauma. 

Medical Evidence Needed: 

• Neurologist documentation specifying neuropathy type, affected nerves, and symptoms. 

• Electrophysiological testing: nerve conduction studies (NCS) and electromyography (EMG) clearly documenting the extent of nerve damage. 

• Physician documentation of reflex tests, sensory deficits, muscle strength measurements, and atrophy. 

• Treatment history documentation, including medications (gabapentin, pregabalin), therapeutic interventions, and results. 

• Documentation detailing numbness, burning, tingling, and pain severity (1-10) and distribution. 

• Functional assessment detailing ambulation safety, assistive device use, falls history. 

Amyotrophic Lateral Sclerosis (ALS) 

A rapidly progressive neurodegenerative condition affecting voluntary muscle control. 

Medical Evidence Needed: 

• Neurologist documentation confirming ALS diagnosis consistent with clinical criteria. 

• EMG/Nerve conduction studies verifying the diagnosis. 

• Clinical records carefully documenting progression, symptom severity, respiratory function. 

• Documentation of swallowing/speech impairments, respiratory limitations, and assistive equipment use. 

• Functional assessments clearly documenting daily activity limitations, personal assistance needs. 

Secondary Neurological Conditions & How to Document Them 

Neurological conditions commonly cause many secondary conditions. Careful documentation is vital for their recognition. 

TBI-Related Secondary Conditions: 

• Mental health disorders (depression, anxiety, PTSD): psychiatric evaluations explicitly linking mental health decline to TBI. 

• Post-traumatic headaches: neurologist documentation clearly linking headache onset and characteristics to prior traumatic brain injury. 

• Sensory impairments: ophthalmology/audiology evaluations linking visual/hearing issues directly to TBI. 

Epilepsy-Related Secondary Conditions: 

• Cognitive impairments: Neuropsychology testing explicitly linking cognitive deficits to seizures or medication side effects. 

• Physical injuries from seizures: ER and orthopedic documentation clearly connecting physical harm or dental injuries to seizure episodes. 

Parkinson’s Disease Secondary Conditions: 

• Autonomic disorders: documentation by gastroenterologists/urologists/cardiologists explicitly linking autonomic issues (such as hypotension, constipation, bladder problems) to Parkinson’s. 

• Cognitive decline and mood disorders: complete psychiatric/neuropsychological assessments explicitly linked to Parkinson’s progression. 

Examples: Weak vs. Strong Documentation 

Migraine Headache: 

Weak Documentation: “Patient has headaches occasionally.” 

Strong Documentation:
“Patient experiences migraine without aura (ICD-10: G43.009), documented frequency of 3-5 episodes monthly, pain rated as severe (8-9/10) lasting 4-6 hours, with associated nausea photophobia, and phonophobia. Episodes are ‘prostrating’, forcing cessation of all activity and requiring bed rest. Patient has documented multiple missed workdays over the past three months. Neurologist has documented unsuccessful trials of preventive medications (Topiramate, Amitriptyline).” 

Peripheral Neuropathy: 

Weak Documentation: “Neuropathy, patient complains of numbness occasionally.” 

Strong Documentation: “Patient diagnosed with diabetic peripheral neuropathy involving both feet and lower legs (ICD-10: E11.42). Consistent numbness, severe nighttime burning pain (7/10) causing significant sleep disturbance reported. EMG shows severe axonal sensory neuropathy. Examination documents lack of reflexes, decreased sensation up to mid-calf, impaired balance requiring cane use, and recent falls.”

Essential Neurological Diagnostic Tests & Documentation 

• MRI: Crucial for documenting structural lesions (TBI, MS). 

• CT Scan: Used to document acute trauma findings (fracture, hemorrhage). 

• EEG: Document epilepsy or seizure disorder. 

• EMG/NCS: Document neuropathy type and severity. 

• Neuropsychological Testing: Documents cognitive deficits across domains. 

Symptom Tracking Tools 

• Migraine Diary: Record date, severity, duration, associated symptoms, triggers, medication use, impact on activities. 

• Seizure Diary: Record seizure date/time, duration, symptoms, recovery, medication, triggers. 

• Cognitive Symptom Tracker: Track memory/concentration issues, mood, pain scores, sleep quality, medication effects. 

Questions for Your Neurologist 

• “Could you explicitly document my diagnosis with ICD-10 codes in your notes?” 

• “Would you note the medical tests and clearly interpret their clinical significance?” 

• “Could you describe clearly in your notes how my symptoms affect my daily living and job?” 

• “Would you state explicitly whether my headaches/seizures are incapacitating/prostrating?”
