Living with Mal de Debarquement

A nervous system condition with a lasting feeling of rocking or swaying, often after a cruise or other travel.

Understanding Mal de Debarquement

Mal de debarquement syndrome is a neurological condition that causes a lasting sensation of motion, most often after water travel.

It most commonly starts after a cruise or other water travel, and less often after air or train travel. People feel rocking, swaying, or bobbing and have trouble with balance. Symptoms may or may not go away over time. They can return after more travel or during stress or illness. It can start at any time in life.

Signs & symptoms

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

  • Poor balance when standing (postural instability)
  • Unsteady walk
  • Dizzy spells (vertigo)
  • Rocking or swaying feeling
  • Tiredness and trouble concentrating
  • Anxiety

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 ear, nose, and throat specialists.

  3. Ask which tests can help

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