Mal de Debarquement Syndrome (MdDS) is a neurological condition that causes a persistent sensation of rocking, swaying, or bobbing, often after traveling by boat, airplane, or train. The condition occurs when the brain has difficulty readjusting to stable surroundings after exposure to prolonged motion.

People with this syndrome may feel as if they are still moving even after the motion has stopped. Although the condition is not very common, it can significantly affect daily activities and overall quality of life.

What Types of Mal De Debarquement Syndrome Exist?

Mal de Debarquement syndrome can be classified based on how the symptoms develop.

Motion-triggered MdDS which occurs after travel involving prolonged motion such as sea voyages, flights, or train journeys
Spontaneous onset MdDS where symptoms appear without recent motion exposure

What Are the Symptoms of Mal De Debarquement Syndrome?

The most common symptom of Mal de Debarquement syndrome is the persistent sensation of movement, even when a person is stationary.

Continuous feeling of rocking, swaying, or bobbing, similar to being on a boat
Symptoms often improve during actual movement such as riding in a vehicle
Difficulty maintaining balance or feeling unsteady
Difficulty concentrating or memory problems
Visual disturbances such as sensitivity to light or trouble focusing
Persistent fatigue and tiredness
Emotional symptoms including anxiety or depression
Headaches or discomfort similar to motion sickness

What Causes Mal De Debarquement Syndrome?

The exact cause of Mal de Debarquement syndrome is not fully understood, but it is believed to involve abnormal processing within the brain's balance system.

Prolonged exposure to passive motion such as boat travel or long flights
Maladaptive changes in brain function related to motion perception
Dysfunction of the vestibular system is responsible for balance
Changes in central nervous system activity affecting motion processing
Possible hormonal or neurological influences
