Trigeminal Neuralgia (Facial Nerve Pain) (cont.)

Trigeminal Neuralgia Causes

  • The condition has no clear-cut cause.
    • Some experts argue that the syndrome is caused by traumatic damage to the nerve as it passes from the openings in the skull to the muscles and tissue of the face. The damage compresses the nerve, causing the nerve cell to shed the protective and conductive coating (demyelination).
    • Others believe the cause stems from biochemical change in the nerve tissue itself.
    • A more recent notion is that an abnormal blood vessel compresses the nerve as it exits from the brain itself.
  • In all cases, though, an excessive burst of nervous activity from a damaged nerve causes the painful attacks.
