What kind of doctor treats Mal de Debarquement Syndrome?
A neurologist, a doctor who treats brain and nerve conditions, or an ENT doctor (an otolaryngologist, who treats ear, nose, and throat conditions) most often diagnoses Mal de Debarquement Syndrome. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Mal de Debarquement Syndrome?
Mal de debarquement syndrome (MdDS) is a rare and poorly understood disorder. It causes a phantom feeling of motion, usually described as rocking, bobbing, or swaying.
Many healthy people feel a short version of this after long travel. It usually lasts seconds to three days. In MdDS, balance problems can last for months to years.
It most often follows sea travel. It can also follow air or land travel.
Symptoms
The main symptom is a lasting sense of motion and rocking. Other symptoms can include:
- Unsteadiness and poor balance.
- Fatigue, mood changes, and confusion.
- Anxiety and depression, which are more common in people with MdDS.
Symptoms tend to get worse when you are not moving, such as when sleeping or standing still. Fast movements, flickering lights, and grocery store aisles can also make them worse.
Symptoms may improve for a short time when you ride in a car or train. They tend to return after the trip. True spinning vertigo and motion sickness are rare.
Causes and who gets it
The true cause is still unknown. It likely involves the body's balance system not adjusting to the surroundings after the trigger ends.
The most common triggers are water-based activities, such as ocean cruising. Less common triggers include airplane travel, extended land travel, and sleeping on water beds.
Most people affected are adult women, but men can have it too. People with migraine may be more likely to have it.
How doctors diagnose it
Diagnosis is mostly based on your history, so the story of your symptoms matters. A feeling of motion that lasts after a cruise, a sailing trip, a long flight, or a long road trip strongly suggests MdDS.
Balance tests are usually normal or show nothing specific in MdDS. They are used to rule out other causes. In general, standard brain MRI scans and inner ear function tests are also normal.
Getting a diagnosis can take up to several years.
Treatment
MdDS is very difficult to treat, and most treatments help little. Vestibular rehabilitation, a form of therapy that trains the balance system, has helped a small number of patients.
Some medicines have modestly eased symptoms. These include benzodiazepines (anti-anxiety medicines) and SSRIs (a type of antidepressant). Follow your doctor's instructions on any medicine.
Anti-nausea medicines and vestibular suppressants, which calm the balance system, have generally been considered unhelpful.
Reducing stress may also help. Magnetic brain stimulation has shown promising effects, but the evidence is limited.
Symptoms may ease over time. They may also return on their own or after another exposure.
When to see a doctor
A short rocking feeling after travel is common in healthy people. Dizziness that stays after travel is highly suggestive of MdDS, so see a doctor if the feeling lasts.
Call 911 or go to the emergency room for sudden dizziness, weakness, or a change in vision, trouble speaking, or fainting.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can listen to your symptoms and travel history and check for other causes. They can also refer you to a neurologist or ENT doctor.
Common questions
What causes Mal de Debarquement Syndrome?
The exact cause is unknown. Travel, especially on water, is the most common trigger.
Who gets Mal de Debarquement Syndrome?
Most people affected are adult women. Men can have it too.
Does Mal de Debarquement Syndrome go away?
It can ease with time, but it may last months to years. Symptoms may also come back.
Is there a test for Mal de Debarquement Syndrome?
Not one that confirms it on its own. Diagnosis is mostly based on your history, and balance tests are usually normal or nonspecific.
