Why Is a Nerve Biopsy Performed?

A nerve biopsy is performed to diagnose various nerve-related conditions, including:

  • Peripheral Neuropathy: To determine the cause of damage to the peripheral nerves, which can result from diabetes, infections, autoimmune diseases, or toxins.
  • Inflammatory Neuropathies: Such as vasculitis, where the blood vessels that supply the nerves become inflamed.
  • Hereditary Neuropathies: To identify genetic disorders that affect nerve function, such as Charcot-Marie-Tooth disease.
  • Amyloidosis: To detect abnormal protein deposits in the nerves.
