Evidence Checklist: Guillain-Barré Syndrome

EMG/nerve conduction study documenting demyelinating or axonal polyneuropathyCritical

Electrodiagnostic testing showing the characteristic GBS pattern: slowed conduction velocity, prolonged distal latencies, absent F-waves, and conduction block consistent with acute inflammatory demyelinating polyneuropathy (AIDP) or AMAN/AMSAN variants.

Lumbar puncture CSF analysis showing cytoalbuminous dissociation

CSF results showing elevated protein with normal or near-normal cell count (albuminocytologic dissociation), the characteristic GBS CSF finding.

Nexus opinion linking GBS to service (at least as likely as not)Critical

Medical opinion connecting GBS to an in-service infection (Campylobacter, CMV, EBV), vaccine administration during service, or surgery.

Current functional assessment documenting residual deficitsCritical

Neurologist evaluation documenting chronic GBS residuals: persistent weakness, fatigue, sensory loss, pain, and autonomic dysfunction that affect daily activities.

Acute hospitalization records and ICU/ventilator recordsCritical

Records from the acute GBS episode including ICU admission, mechanical ventilation, plasmapheresis, or IVIG treatment. Establishes severity of initial episode.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.

Completed DBQ Peripheral Nerves ConditionsCritical

VA standardized form capturing residual motor and sensory deficits from GBS for rating under peripheral nerve diagnostic codes.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
