Living with CANOMAD syndrome

A rare long-term immune condition that damages nerves, affecting balance, sensation, and eye movement.

Understanding CANOMAD syndrome

CANOMAD syndrome is a rare, long-lasting nerve condition in which the immune system damages the coating around nerves (chronic immune-mediated demyelinating polyneuropathy).

The name stands for Chronic Ataxic Neuropathy, Ophthalmoplegia, IgM paraprotein, Cold Agglutinins, and Disialosyl antibodies. It usually shows up in adults and older adults. GARD says it is caused by anti-diasialosyl antibodies in the body.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the signs:

  • Loss of muscle, tendon, and joint sensation
  • Unsteady walking and poor balance (ataxia)
  • Tingling around the mouth or in the arms and legs
  • Paralysis of the eye muscles
  • Trouble swallowing and speaking
  • Rarely, weakness of the breathing muscles

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    The Foundation for Peripheral Neuropathy may keep lists of experts for this condition.

  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits

GARD says CANOMAD syndrome is caused by anti-diasialosyl antibodies in the body. These are immune proteins that react against the body's own tissue.
