Living with Locked-in syndrome

A rare nerve condition with complete paralysis of voluntary muscles except the eyes, while the person stays aware and can think.

Understanding Locked-in syndrome

Locked-in syndrome is a rare neurological disorder with complete paralysis of voluntary muscles, except for those that control the eyes.

People are conscious and can think and reason but cannot speak or move. They can use vertical eye movements and blinking to communicate. It can occur at any time in life.

Signs & symptoms

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

  • Paralysis of voluntary muscles except the eyes
  • Inability to speak
  • Double vision
  • Excess saliva
  • Feeding difficulties
  • Voice changes

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.
