Educational scope notice: This is a study note for medical students, not medical advice, diagnosis, or treatment guidance. Clinical management should follow local protocols and current guidelines.

Peripheral neuropathy means damage to peripheral nerves. Different causes can produce similar symptoms, so understanding the pattern helps make sense of the possibilities.

Start with the foundations if this topic is new to you. The remaining notes explore specific patterns and causes, then diagnosis and treatment.

Choose a route through the topic

  • Foundations explains how nerves are built, what distinguishes axonal from demyelinating injury, and how sensory, motor, and autonomic signs point to the site of damage.
  • Entrapment Syndromes covers focal compression neuropathies such as carpal tunnel and cubital tunnel syndromes, other single-nerve lesions, and the stepwise asymmetric pattern of mononeuritis multiplex.
  • Polyneuropathy Classification sets out the four-axis framework of tempo, fibre type, mechanism, and etiology, with the common acute and chronic causes and the extranervous clues that narrow them.
  • Diabetic Neuropathy follows the most common cause of polyneuropathy, from distal symmetric disease through small-fibre and autonomic patterns to the painful proximal syndrome that behaves differently.
  • Inflammatory and Immune Neuropathies covers the treatable immune-mediated diseases, including CIDP and multifocal motor neuropathy, paraprotein-associated neuropathies, and chemotherapy-induced disease.
  • Guillain-Barre Syndrome explains the acute ascending emergency, its demyelinating and axonal forms, the post-infectious mechanism, diagnosis, and immunotherapy.
  • Diagnosis traces the workup from history and examination through laboratory testing, nerve conduction studies, and selective imaging or biopsy.
  • Treatment follows cause-directed therapy by etiology, the pharmacological approach to neuropathic pain, and the interventions to avoid in specific diseases.

The useful sequence is foundations first, then the pattern notes, then diagnosis and treatment.
