MdDS Care in Calgary

Mal de Débarquement Syndrome Assessment in Calgary

Mal de Débarquement Syndrome can feel disorienting, persistent, and difficult to explain. You may feel as though you are still moving, rocking, swaying, or floating long after a boat ride, flight, or road trip has ended. For some people, these sensations become more noticeable when standing still or in visually stimulating environments.

What is Mal de Débarquement Syndrome?

Mal de Débarquement Syndrome (MdDS) is a neurological condition in which the brain continues to perceive motion even after movement has stopped. It is most commonly triggered after exposure to passive motion such as a cruise, long flight, or extended travel, although it can also develop without a clear trigger. Unlike typical vertigo conditions where symptoms worsen with movement, many individuals with this syndrome report temporary relief when they are back in motion, such as driving. This paradox reflects a disruption in how the brain adapts to and recalibrates motion signals from the vestibular system.

Common Symptoms of MdDS

Patients typically describe a constant sensation of rocking, swaying, or bobbing, as if they are still on a boat. This sensation is often persistent and can last for weeks, months, or even years if not properly addressed. In addition to the primary motion sensation, many individuals experience brain fog, difficulty concentrating, visual sensitivity, fatigue, and heightened anxiety. These symptoms are not simply physical; they reflect a broader disruption in how the brain integrates sensory input from the inner ear, eyes, and body.

What Causes MdDS?

The exact cause is not fully understood, but current evidence suggests that Mal de Débarquement Syndrome involves maladaptation within the brain’s motion-processing centers. During prolonged exposure to motion, the brain adjusts to maintain balance and orientation. In this condition, that adaptation does not properly reverse once the motion stops. This leads to persistent signaling within the vestibular system, even in the absence of movement. Research in Functional Neurology and vestibular science suggests that abnormal neural oscillations and sensory integration patterns may play a key role.

How We Assess MdDS

Our assessment focuses on understanding how your brain and balance systems are responding after exposure to motion, such as a cruise, flight, long drive, or other travel-related trigger. MdDS is commonly described as a persistent rocking, swaying, bobbing, or floating sensation, often without true spinning vertigo. During the assessment, we take a detailed health history to understand when your symptoms began, what type of motion exposure may have triggered them, how long they have persisted, and whether they improve or worsen in specific situations, such as while driving, standing still, lying down, or being in visually busy environments.

MdDS Care Plan

Care for Mal de Débarquement Syndrome is individualized and focuses on improving how the nervous system processes motion, balance, and spatial orientation. Depending on your findings, care may include vestibular and visual rehabilitation exercises, eye-head coordination training, balance and proprioceptive retraining, neurological stimulation exercises, gradual exposure to movement or visual triggers, and cervical spine therapy when neck involvement is present. Care of this kind depends on consistent appointments and on practicing your at-home exercise program between visits, and your plan is agreed with you before care begins.

When should you seek care for MdDS?

An Initial Intake Assessment may be appropriate if you experience a persistent rocking, swaying, bobbing, or floating sensation after travel or motion exposure, especially if the symptoms last more than a few days. MdDS may also be considered when symptoms feel worse while sitting or standing still, but temporarily improve when you are back in passive motion, such as riding in a car. An assessment may also be helpful if you have ongoing imbalance, disorientation, visual motion sensitivity, difficulty concentrating, fatigue, or symptoms that interfere with work, driving, exercise, or daily activities.

Frequently Asked Questions

What triggers Mal de Débarquement Syndrome?

The most common trigger is prolonged exposure to passive motion such as a cruise, flight, or long road trip. In some cases, symptoms may begin without a clearly identifiable trigger, which is referred to as spontaneous onset.

How long does Mal de Débarquement Syndrome last?

Symptoms can last from weeks to months, and in some cases years. Without targeted intervention, the brain may remain in this maladapted state longer than expected.

Does Mal de Débarquement Syndrome go away on its own?

Some individuals experience spontaneous resolution, especially in early stages. However, persistent cases often require targeted therapy to help the brain recalibrate.

Is it a problem with the inner ear?

Not entirely. While the vestibular system is involved, the condition is primarily driven by how the brain processes motion signals rather than a structural issue within the inner ear.

Can Mal de Débarquement Syndrome be treated?

Yes. Targeted neurological and vestibular rehabilitation approaches can help reduce symptoms and improve function by retraining the brain’s processing of motion and balance.

Is Mal de Débarquement Syndrome the same as vertigo?

No. Although both involve dizziness, the sensations and mechanisms differ. Mal de Débarquement Syndrome typically involves a constant rocking feeling, while vertigo often presents as spinning triggered by movement.

Have Questions Before You Commit to Care?

Talk It Through in a 30-Minute Case Review Consultation

Our approach is structured, assessment-led and our care requires active participation, and patients should understand the process before committing. If you are ready to proceed, you can book an Initial Intake Assessment directly. If you still have questions, a 30-minute Case Review Phone Consultation is available first. During the call we briefly review your health history, current symptoms and previous testing, explain how our integrated approach and care process work, outline the time and financial commitment involved, and discuss how our care could complement the services you are already receiving. The Case Review Consultation is optional. It helps you decide whether to book an Initial Intake Assessment; it is not a substitute for an in-person assessment or a medical diagnosis.
