OBJECTIVE: Mal de debarquement syndrome (MdDS) is a balance disorder that typically starts after an extended exposure to passive motion, such as a boat or plane ride. Management is typically supportive (e.g. physical therapy), and symptoms that persist beyond 6 months have been described as unlikely to remit. This study was conducted to evaluate the response of patients with MdDS to management with migraine prophylaxis, including lifestyle changes and medical therapy. STUDY DESIGN: Prospective review...

Mal de débarquement syndrome (MdDS) is typified by a prolonged rocking sensation - for a month or longer - that begins immediately following a lengthy exposure to motion. The provoking motion is usually a sea voyage. About 80% of MdDS sufferers are women, and most of them are middle-aged. MdDS patients are troubled by more migraine headaches than controls. Unlike dizziness caused by vestibular disorders or motion sickness, the symptoms of MdDS usually improve with re-exposure to motion. The long duration of symptoms - a month or more - distinguishes MdDS from land-sickness...

BACKGROUND: Mal de debarquement syndrome is a medically refractory disorder characterized by chronic rocking dizziness that occurs after exposure to passive motion. Repetitive transcranial magnetic stimulation (rTMS) can acutely suppress the rocking dizziness but treatment options that extend the benefit of rTMS are needed. OBJECTIVES: 1) To determine whether transcranial direct current stimulation (tDCS) added after rTMS can extend the benefit of rTMS; 2) to determine whether participants can safely perform tDCS at home...

Mal de debarquement (MdD) is a subjective perception of self-motion after exposure to passive motion, in most cases sea travel, hence the name. Mal de debarquement occurs quite frequently in otherwise healthy individuals for a short period of time (several hours). However, in some people symptoms remain for a longer period of time or even persist and this is then called mal de debarquement syndrome (MdDS). The underlying pathogenesis is poorly understood and therefore, treatment options are limited. In general, limited studies have focused on the topic, but the past few years more and more interest has been attributed to MdDS and its facets, which is reflected by an increasing number of papers...

Mal de Debarquement Syndrome (MDS) is a rare, understudied, underdiagnosed, and self-limiting condition. Etiology and incidence are unknown. It is characterized by abnormal sensation of motion/balance reported after travel by air, land, and sea; being reexposed to motion/activity relieves it. Symptoms may last from minutes to years. Workup though required reveals no findings; it is a diagnosis of exclusion. While no efficacious treatment exists, amitriptyline and benzodiazepines as well as supportive therapy have proved to be useful...

BACKGROUND: Mal de debarquement syndrome (MdDS) is a disorder of chronic self-motion perception that occurs though entrainment to rhythmic background motion, such as from sea voyage, and involves the perception of low-frequency rocking that can last for months or years. The neural basis of this persistent sensory perception abnormality is not well understood. METHODS: We investigated grey matter volume differences underlying persistent MdDS by performing voxel-based morphometry on whole brain and pre-specified ROIs in 28 individuals with MdDS and comparing them to 18 age, sex, and handedness matched controls...

Most patients with the acute vestibular syndrome (AVS) have vestibular neuritis or stroke or, in the setting of trauma, a posttraumatic vestibular cause. Some medical and nonstroke causes of the AVS must also be considered. Multiple sclerosis is the most common diagnosis in this group. Other less common causes include cerebellar masses, inflammation and infection, mal de debarquement, various toxins, Wernicke disease, celiac-related dizziness, and bilateral vestibulopathy. Finally, there may be unmasking of prior posterior circulation events by various physiologic alterations such as alterations of temperature, blood pressure, electrolytes, or various medications, especially sedating agents...

Mal de debarquement syndrome (MdDS) is a rare and poorly understood condition of perceived continual motion. Using a multiple-case design (n = 13; 8 f; 63.5 ± 12.6 years), this study investigated the efficacy of eight 20-min sessions, over 4 weeks, of repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral pre-frontal cortex. Compared to sham, rTMS demonstrated improvement in balance and confidence in daily living activities. rTMS shows promise for the treatment of MdDS. However, larger trials with longer intervention periods are required...

Mal de Debarquement Syndrome (MdDS) is an enigmatic neurotological disorder with high morbidity, psychosocial burden, and few treatment options. Fortunately, there has been recent growth in scientific interest in understanding the biological basis of and in treating MdDS. Recent studies using functional neuroimaging have shown increased glucose metabolism in the left entorhinal cortex (EC) and amygdala in the setting of decreased prefrontal and temporal cortex metabolism in subjects with persistent MdDS. The EC is a key player in processing and gating spatial information to be stored in the hippocampus and is a major driver of brain oscillations...

Mal de debarquement syndrome (MdDS) is a chronic disorder of imbalance characterized by a feeling of rocking and swaying. The medical treatment for MdDS is still limited. Motivated by our previous pilot study that demonstrates the promising clinical efficacy of repetitive transcranial stimulation (rTMS) in MdDS patients, a novel rTMS paradigm, i.e., 1 Hz stimulation over ipsilateral dorsal lateral prefrontal cortex (DLPFC) with respect to the dominant hand followed by 10 Hz stimulation over contralateral DLPFC, was proposed and conducted in MdDS in the present study...

The mal de debarquement syndrome (MdDS), a continuous feeling of swaying, rocking, and/or bobbing, generally follows travel on the sea. The associated symptoms cause considerable distress. The underlying neural mechanisms are unknown, and to date there have been no effective treatments for this condition. Results in monkeys and humans suggested that MdDS was caused by maladaptation of the vestibulo-ocular reflex (VOR) to roll of the head during rotation. We studied 24 subjects with persistent MdDS (3 males, 21 females; 19...

BACKGROUND AND PURPOSE: Persistent mal de debarquement is an uncommon disorder occurring after a sea voyage, or a plane or train trip. Symptoms include unsteadiness, rocking sensation, visual motion intolerance, cognitive slowing, and excessive fatigue. It is thought to be a result of faulty multisensory adaptation. The purpose of this case report was to describe the use of sensory reweighting, a therapeutic approach aimed at reweighting the balance between the 3 sensory systems, to decrease symptoms and increase functional abilities of a woman with persistent mal de debarquement...

The long-lasting neuromodulatory effects of repetitive transcranial magnetic stimulation (rTMS) are of great interest for therapeutic applications in various neurological and psychiatric disorders, due to which functional connectivity among brain regions is profoundly disturbed. Classic TMS studies selectively alter neural activity in specific brain regions and observe neural activity changes on nonperturbed areas to infer underlying connectivity and its changes. Less has been indicated in direct measures of functional connectivity and/or neural network and on how connectivity/network alterations occur...

BACKGROUND: Exposure to unfamiliar motion patterns commonly results in motion sickness and a false perception of motion, termed mal de debarquement, on the return to stable conditions. OBJECTIVE: To investigate whether motion sickness severity is correlated with the duration and severity of mal de debarquement; to study the possible preventive effect of projecting earth-referenced scenes (an artificial horizon) during exposure to motion on the development of mal de debarquement...

Although vertigo is a common complaint with patients presenting to an ED, some uncommon causes also must be considered. This report focuses on a woman who developed sudden-onset vertigo with associated mental status changes after a long-distance flight. Her symptoms were consistent with mal de debarquement syndrome, an uncommon cause of vestibular dysfunction.

Sea travel mandates changes in the control of the body. The process by which we adapt bodily control to life at sea is known as getting one's sea legs. We conducted the first experimental study of bodily control as maritime novices adapted to motion of a ship at sea. We evaluated postural activity (stance width, stance angle, and the kinematics of body sway) before and during a sea voyage. In addition, we evaluated the role of the visible horizon in the control of body sway. Finally, we related data on postural activity to two subjective experiences that are associated with sea travel; seasickness, and mal de debarquement...

BACKGROUND: Chronic rocking dizziness, often described as the feeling of being on a boat, is classically triggered by prolonged exposure to passive motion. Patients with this motion-triggered sensation of rocking, which is also known as MAL DE DEBARQUEMENT SYNDROME , often develop new onset headaches along with the dizziness. Chronic rocking dizziness has also been noted in vestibular migraine, occurring without a motion trigger. We sought to clarify the association between both motion-triggered (MT) and non-motion-triggered (non-MT) chronic rocking dizziness and headache history...
