Large Fiber Neuropathy

What is it?

  • Large Fiber Neuropathy (LFN) is a condition that affects the large nerve fibers — these are the nerves that affect motor control and balance
  • Symptoms of LFN can include balance issues, joint and muscle weakness, and reduced reflexive responses
  • Some patients also experience burning pain or coldness and electric shock-like brief painful sensations
  • Small Fiber Neuropathy can sometimes degenerate into Large Fiber Neuropathy

How is it diagnosed?

  • LFN can be diagnosed using:
    • Magnetic Resonance Imaging (MRI)
    • Electromyography (EMG) studies
    • Nerve Conduction Velocity (NCV) studies
  • LFN can also be diagnosed by medical and a physical exam that involves functional neurophysiologic testing
