Living with Foix chavany Marie syndrome

A rare nerve condition affecting the muscles of the face, throat and tongue, causing severe trouble with speech and swallowing.

Understanding Foix chavany Marie syndrome

Foix-Chavany-Marie syndrome is a rare nerve condition that affects the lower cranial nerves, which control muscles of the face, throat, tongue and chewing.

It causes severe slurred speech (dysarthria) and trouble swallowing (dysphagia) from paralysis of these muscles on both sides. A key feature is that the muscles can still move on their own, such as in yawning or laughing, even when the person can't move them on purpose. It can occur at any time in life.

Signs & symptoms

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

  • Severe slurred speech (dysarthria)
  • Trouble swallowing (dysphagia)
  • Weak facial, tongue and chewing muscles
  • Changes in the voice
  • Seizures
  • Developmental delay or thinking problems

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.
