Introduction: Mal de Debarquement Syndrome (MdDS) is a rare central vestibular disorder characterised by a constant sensation of motion (rocking, swaying, bobbing), which typically arises after motion experiences (e.g. sea, air, and road travel), though can be triggered by non-motion events. The current standard of care is non-specific medications and interventions that only result in mild-to-moderate improvements. The vestibular ocular reflex (VOR) rehabilitation protocol, a specialised form of rehabilitation, has shown promising results in reducing symptoms amongst people with MdDS. Accumulating evidence suggests that it may be possible to augment the effects of VOR rehabilitation via non-invasive brain stimulation protocols, such as theta burst stimulation (TBS). Methods: The aim of this randomised controlled trial was to evaluate the effectiveness of intermittent TBS (iTBS) over the dorsolateral prefrontal cortex in enhancing the effectiveness of a subsequently delivered VOR rehabilitation protocol in people with MdDS. Participants were allocated randomly to receive either Sham (n = 10) or Active (n = 10) iTBS, followed by the VOR rehabilitation protocol. Subjective outcome measures (symptom ratings and mental health scores) were collected 1 week pre-treatment and for 16 weeks post-treatment. Posturography (objective outcome) was recorded each day of the treatment week. Results: Significant improvements in subjective and objective outcomes were reported across both treatment groups over time, but no between-group differences were observed. Discussion: These findings support the effectiveness of the VOR rehabilitation protocol in reducing MdDS symptoms. Further research into iTBS is required to elucidate whether the treatment has a role in the management of MdDS. TRN: ACTRN12619001519145 (Date registered: 04 November 2019). [ABSTRACT FROM AUTHOR]

- Abstract
Introduction: Mal de Debarquement Syndrome (MdDS) is a debilitating neurootological disorder. Patients experience almost continuously a perception of self-motion. This syndrome can be motion-triggered (MT-MdDS), such as on a boat, or occur spontaneously or have other triggers (SO-MdDS) in the absence of such motion. Because the pathophysiological mechanism is unknown, treatment options and symptom management strategies are limited. One available treatment protocol involves a readaptation of the vestibular ocular reflex (VOR). This study assesses the effectiveness of vestibulo-ocular reflex (VOR) readaptation in 131 consecutive patients with a fixed protocol. Methods: We administered 131 treatments involving optokinetic stimulation (OKS) paired with a fixed head roll at 0.167 Hz over two to five consecutive days. Each day, four-minute treatment blocks were scheduled twice in the morning and afternoon. Treatment effectiveness was evaluated through questionnaires and posturography. Results: We observed significant improvements in the visual analog scale (VAS), MdDS symptom questionnaire, and posturography measures from pre- to posttreatment. No significant differences were found in outcome variables between MT- and SO-MdDS onsets. Conclusion: Symptoms improved subjectively and objectively in patients' posttreatment. The overall success rate was 64.1%, with no significant difference between MT (64.2%) and SO (63.3%). This study supports the conclusion that VOR readaptation treatment provides relief for two-thirds of MdDS patients, irrespective of the onset type. Based on consistency in the findings, we propose a standardized method for treatment of MdDS based on the OKS with head roll paradigm. [ABSTRACT FROM AUTHOR]

- Abstract
Mal de debarquement syndrome (MdDS), also known as "the sickness of disembarkment," is characterized by a persistent bobbing, rocking, or swaying sensation reported by patients long after they have completed travel on a boat or other forms of extended transportation. A detailed patient history, focusing on specific inquiries about recent boat or ship travel, is crucial for a timely diagnosis. The syndrome is unique in that reintroducing similar movements, such as driving, swinging, or returning to the boat, alleviates symptoms temporarily. We describe the case history of a 28-year-old male who experienced a persistent illusion of ground movement for six months following a fishing expedition. The patient reported alleviated symptoms when re-exposed to movements such as driving or swinging. The patient had undergone extensive medical workups and imaging tests under multiple physicians before being diagnosed with MdDS. MdDS is a commonly misdiagnosed, underdiagnosed, unreported, and unrecognized condition. Diagnosing MdDS requires a detailed medical and travel history, accompanying an understanding that the symptoms improve upon re-exposure to the same or similar motion., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Mal de debarquement syndrome (MdDS) is a pathological condition characterized by rocking, swaying, and/or a sense of imbalance. The two types of MdDS are known as motion triggered MdDS and spontaneous or other onset MdDS. The purpose of this systematic review was to evaluate the effectiveness of vestibular rehabilitation on individuals experiencing the symptoms of MdDS using valid and reliable outcome measures. MEDLINE, ProQuest Medical Database, and Web of Science were the databases utilized in the search process. The search terms included 'mal de debarquement' AND 'intervention' OR 'management' OR 'rehabilitation' OR 'therapy' OR 'treatment'. The Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence was utilized in evaluating the evidence level for all of the included articles, and a 10-item tool created by Medlicott and Harris was utilized in evaluating the methodological rigor for all of the included articles. Seven articles met the eligibility requirements based upon the inclusion and exclusion criteria, and these articles were qualitatively analyzed. The intervention focused on traditional vestibular rehabilitation in two of the studies and on optokinetic stimulation in the other five studies. Optokinetic stimulation is designed to induce re-adaptation of the vestibulo-ocular reflex. This systematic review found that optokinetic stimulation required a much shorter treatment duration than traditional vestibular rehabilitation to significantly improve the balance and decrease the symptoms of individuals affected with MdDS. Clinicians should consider using optokinetic stimulation when treating individuals diagnosed with MdDS, especially those with the motion-triggered subtype. [ABSTRACT FROM AUTHOR]

Background Mal de Debarquement Syndrome (MdDS) has a stereotypical presentation of symptoms including continuous rocking/swaying sensations described as feeling like one is "still on the boat," following travel, especially on water vessels. MdDS is even more notorious for the duration of symptoms that can persist months or years, and historically this condition has escaped effective treatments. Purpose This case study presents a case of classic MdDS that was effectively treated in an Audiology-Vestibular clinic. Treatment consisted of three, relatively short-lived vestibular rehabilitation sessions using the "Roll Readaptation" technique that has previously been reported in Neurology journals. Study Sample The study sample includes a 48-year-old female with a history of MdDS following two separate ocean cruises. She underwent vestibular evaluation and was treated with a treatment paradigm aimed to readapt the central vestibular system and vestibular-ocular reflex. Results This report focuses on a brief review of current symptomology and diagnostic criteria of MdDS, underlying pathophysiology and application of a relatively new treatment technique in an audiology clinic. This patient was shown full-field, omni-directional optokinetic (OPK) stimulus while rolling her head rhythmically for up to 4 minutes at a time. After three treatment sessions, the patient had a significant reduction in subjective symptoms and returned to full-time work. She had previously been off work for nearly 3 months. Conclusion Individuals with MdDS suffer large daily and work life disruptions due to the persistent nature of symptoms, and their physical manifestations. In addition, they have historically had minimal treatment options. This case demonstrates that audiologists with proper equipment may have the potential to readily offer treatment for a previously "untreatable" condition. [ABSTRACT FROM AUTHOR]

Objective: To report on the psychological, personality, and behavioral profiles of individuals with persistent Mal de Débarquement Syndrome (MdDS). Materials and methods: Individuals with MdDS who participated in neuromodulation clinical trials between May 2013 and June 2019 completed a series of standardized psychological questionnaires and underwent the Structural Clinical Interview for DSM-IV-TR (SCID) for specific psychiatric diagnoses. All data reported are from baseline assessments prior to any study interventions. Scores were compared to population norms for adult women. Results: Complete datasets were available for 55 women. Mean age of onset of MdDS was 49.0 ± 11.9 years (range 22–69 years) and median duration of illness of 22 months (6 months–20 years). SCID results were as follows: healthy (48.1%), any lifetime Major Depressive Disorder (35.2%, 7.4% current); any lifetime history of anxiety disorder (11.1%); any lifetime substance use disorders (18.5%, 0% current). Compared to population norms, the MdDS group scored significantly higher on the Patient Health Questionnaire-9 depression scale and the Generalized Anxiety Disorder 7 (GAD-7) anxiety scale, but only the GAD-7 correlated with symptom severity. The NEO-Five Factor Inventory for personality, Positive and Negative Affect Schedule, Behavioral Inhibition System/Behavioral Activation System Scale, and the Empathy Quotient metrics did not correlate with duration of illness. Disability assessed by the 12-item World Health Organization Disability Assessment Schedule 2.0 was 25.7 ± 6.7, comparable to reports for concussion. Disability correlated with severity of depression, anxiety, neuroticism, and affect but not to severity of MdDS. Conclusions: Psychological profiles of MdDS relate to disability but not to duration of illness. [ABSTRACT FROM AUTHOR]

ObjectiveMal 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 designProspective review.SettingAmbulatory setting at a tertiary care medical center.MethodsClinical history, detailed questionnaires, and audiograms were used to diagnose patients with MdDS. Those patients with the diagnosis of the MdDS were placed on our institutional vestibular migraine management protocol. Treatment response was assessed with a quality-of-life (QOL) survey and visual analog scale.ResultsFifteen patients were diagnosed with MdDS, with a predominance of females (73%) and a mean age of 50 ± 13 years. Eleven patients (73%) responded well to management with a vestibular migraine protocol, which included lifestyle changes, as well as pharmacotherapy with verapamil, nortriptyline, topiramate, or a combination thereof. In comparison, a retrospective control group of 17 patients demonstrated a lower rate of improvement when treated with vestibular rehabilitation and physical therapy.ConclusionManagement of MdDS as vestibular migraine can improve patients' symptoms and increase the QOL. Nearly all the patients suffering from MdDS had a personal or family history of migraine headaches or had signs or symptoms suggestive of atypical migraine.Level of evidence4 Laryngoscope, 127:1670-1675, 2017.

Vestibular migraine is combination of migraine and vestibular symptoms. In clinical examination it can be replaced with benign paroxysmal positional vertigo (BPPV) cupulolithiasis, but also BPPV is common comorbidity in migraine patients. There is also high association between vestibular migraine and Mal de Debarquement syndrome. Patient came to hospital with vertigo that was diagnosed as left PC-BPPV canalolithiasis. After first Epley's maneuver symptoms didn't resolved. Week after, at second Epley's maneuver performed patient developed left PC-BPPV cupulolithiasis. Month after, at third Epley's maneuver BPPV resolved but patient developed Mal de Debarquement syndrome. Laboratory testing showed hyperhomocisteinemia and homozygous MTHFR C677T and PAI, with low vitamin D. After reviewing the vestibular symptoms in the first attack which was misdiagnosed as BPPV canalolithiasis, and history of migraine, patient was diagnosed with vestibular migraine. Patient well responded to migraine diet and supplementation with B complex. Vestibular disorders are similar to each other and they can overlap. More attention in taking detailed medical history should be given to patients with vertigo or dizziness.

BACKGROUND: To examine whether the self-initiated exercise in Ménière’s disease fits the characteristics of the balance problems. METHODS: This retrospective study included 539 people with Ménière’s disease belonging to the Finnish Ménière Federation. The mean age was 61.9 years with a mean history of Ménière’s disease of 15.6 years. The data were collected with an online questionnaire. RESULTS: In total, 30% of the patients did not do any training, 23% did training once a week, 22% did 2-3 times a week, and 26% did the training daily. The most common training exercises were different self-training exercises (26%) followed by walking (16%), guided training (15%), viewing plus balance training (10%), and viewing training (4%). Non-defined balance problems (18%) were associated with recent vertigo attacks. Swaying type of balance problems were present in 23% and they used all types of training programs. Rocking type of balance disorder was present in 8% and they preferred guided training exercises. Tripping off type of balance disorder was present in 25% and they preferred viewing plus balance training. CONCLUSIONS: The type of self-training used was related to the type of balance problems reported. When choosing the vestibular rehabilitation in Ménière’s disease, the type of balance disorder should be characterized and the rehabilitation program should be individually tailored.

Objective: To determine whether remotely-monitored transcranial alternating current stimulation (tACS) may be a viable and safe treatment option for Mal de Débarquement Syndrome (MdDS). Background: Mal de Débarquement Syndrome is a neurotological disorder characterized by persistent oscillating vertigo that is triggered by entrainment to passive oscillatory motion such as occurs during water-based travel. Treatment options for MdDS are limited, variably effective, and can be undone by further travel. Design and Methods: This was a remotely-monitored open-label optional extension phase of a double-blind randomized onsite study of tACS for medically refractory MdDS. The primary goal was to determine safety, feasibility, and blinded participant feedback. The secondary goal was to determine efficacy. Thirteen participants (all women), aged 22–67 years, experiencing a duration of illness of 11–72 months, were a subset of 24 individuals who participated in an on-site study of tACS. They had either not responded to the on-site protocol or had relapsed after travel home. Treatment accessories and a tablet controlled tACS stimulator (Pulvinar XCSITE-100) were mailed to participants. Three teaching sessions were performed via webcam followed by on-going remote monitoring of treatment logs and participants' reports through a daily on-line diary and weekly questionnaires. Treatment continued until an effective protocol was administered for 4 weeks and then tapered over 4 weeks. Participants completed a blinded feedback survey and a debriefing interview at the completion of the entire study. Results: Treatment duration ranged from 4 to 31 weeks followed by a 4-week taper accounting for 578 verified sessions. Of the 13 total participants, seven agreed or agreed strongly in the blinded survey that tACS treatment was beneficial; 2) Twelve were comfortable utilizing tACS on their own; 3) Eleven preferred stimulation above their individual alpha frequency; 4) Side effects were generally mild and typical of tACS. In the debriefing interview completed 2–9 months after the last stimulation, five participants reported doing "great," with no to minimal symptoms, four reported doing "good," with moderate symptoms, and four reported no change compared to pre-study baseline. Conclusion: Remotely-monitored tACS may be a safe treatment option for MdDS with the potential for lasting outcomes, increased accessibility, and reduction in travel-related treatment reversal.

- Abstract
Mal de Debarquement Syndrome (MdDS) is a debilitating neuro-otological disorder where individuals consistently feel self-motion, often triggered by motion like being on a boat (MT-MdDS). Due to the unknown pathophysiological mechanism, available treatment options for managing symptoms are limited. Our objective was to develop a virtual reality application (VRA) to simulate the full field optokinetic stimulation (OKS) booth and evaluate its efficacy compared to the standard treatment. In our randomized, open, non-inferiority clinical trial with 30 MT-MdDS patients, 15 received the OKS booth and 15 the new VRA over four consecutive days. Two 4-min treatment blocks were scheduled in the morning and afternoon, with a total of four blocks. Treatment effectiveness was evaluated through questionnaires and posturography. Our findings suggest that the choice of modality does not significantly differ in achieving an overall improvement in symptoms. We advocate that the VRA can be used as an accessible alternative to the booth method worldwide, effectively mitigating MdDS symptoms and enhancing the QoL of numerous MdDS patients., (Copyright © 2024 The Author(s).

- Abstract
Objectives/Hypothesis: Mal de débarquement syndrome (MDDS) is characterized by a persistent rocking sensation, as though on a boat. It may occur following exposure to passive motion (motion‐triggered MDDS [MT‐MDDS]), or spontaneously (spontaneous‐onset MDDS [SO‐MDDS]). This study investigated the characteristics of MDDS patients with vestibular migraine (MDDS‐VM) to those without (MDDS‐O). Study Design: Retrospective review. Methods: Retrospective, single‐center study of 62 patients with MDDS. Clinical characteristics, Dizziness Handicap Inventory (DHI), Migraine Disability Assessment Score (MIDAS), job impact, and optimal treatment(s) were studied. Results: There were 23 MDDS‐O (19 women), and 39 MDDS‐VM (35 women) patients. Comparisons between MDDS‐VM and MDDS‐O showed significant differences in age of onset (41 vs. 52 years, P =.005), interictal visually induced dizziness (89.7% vs. 30.4%, P <.001), interictal head motion‐induced dizziness (87.2% vs. 47.8%, P =.001), other vestibular sensations (59% vs. 13%, P <.001), interictal aural symptoms (25.6% vs. 0%, P =.008), number of interictal symptoms (4.3 vs. 2.3, P <.001), total DHI score (54.9 vs. 38.1, P =.005), DHI‐P (physical domain) score (16.1 vs. 10, P =.004), DHI‐F (functional domain) score (20.9 vs. 15.7, P =.016 MIDAS (4.6 vs. 32, P =.002), and job resignations (23.2% vs. 5%, P =.016). On the other hand, between‐group comparisons for MT‐MDDS and SO‐MDDS did not reveal any significant differences whatsoever. For optimal treatment, venlafaxine was the most used (27.3%) in all groups. For MDDS‐VM, antiepileptic drugs and migraine preventive vitamins were also useful in relieving symptoms. Conclusions: MDDS‐VM patients appear to be more disabled than MDDS‐O, in terms of severity of dizziness, job impact, and number of symptoms, but have good potential for improvement, particularly with migraine prophylactic treatment.

Mal de débarquement syndrome (MdDS) is a motion-induced disorder of oscillating vertigo that persists after the motion has ceased. The neuroimaging characteristics of the MdDS brain state have been investigated with studies on brain metabolism, structure, functional connectivity, and measurements of synchronicity. Baseline metabolism and resting-state functional connectivity studies indicate that a limbic focus in the left entorhinal cortex and amygdala may be important in the pathology of MdDS, as these structures are hypermetabolic in MdDS and exhibit increased functional connectivity to posterior sensory processing areas and reduced connectivity to the frontal and temporal cortices. Both structures are tunable with periodic stimulation, with neurons in the entorhinal cortex required for spatial navigation, acting as a critical efferent pathway to the hippocampus, and sending and receiving projections from much of the neocortex. Voxel-based morphometry measurements have revealed volume differences between MdDS and healthy controls in hubs of multiple resting-state networks including the default mode, salience, and executive control networks. In particular, volume in the bilateral anterior cingulate cortices decreases and volume in the bilateral inferior frontal gyri/anterior insulas increases with longer duration of illness. Paired with noninvasive neuromodulation interventions, functional neuroimaging with functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and simultaneous fMRI-EEG have shown changes in resting-state functional connectivity that correlate with symptom modulation, particularly in the posterior default mode network. Reduced parieto-occipital connectivity with the entorhinal cortex and reduced long-range fronto-parieto-occipital connectivity correlate with symptom improvement. Though there is a general theme of desynchronization correlating with reduced MdDS symptoms, the prediction of optimal stimulation parameters for noninvasive brain stimulation in individuals with MdDS remains a challenge due to the large parameter space. However, the pairing of functional neuroimaging and noninvasive brain stimulation can serve as a probe into the biological underpinnings of MdDS and iteratively lead to optimal parameter space identification.

Baseline metabolism and resting-state functional connectivity studies indicate that a limbic focus in the left entorhinal cortex and amygdala may be important in the pathology of MdDS, as these structures are hypermetabolic in MdDS and exhibit increased functional connectivity to posterior sensory processing areas and reduced connectivity to the frontal and temporal cortices. Both structures are tunable with periodic stimulation, with neurons in the entorhinal cortex required for spatial navigation, acting as a critical efferent pathway to the hippocampus, and sending and receiving projections from much of the neocortex. Voxel-based morphometry measurements have revealed volume differences between MdDS and healthy controls in hubs of multiple resting-state networks including the default mode, salience, and executive control networks. In particular, volume in the bilateral anterior cingulate cortices decreases and volume in the bilateral inferior frontal gyri/anterior insulas increases with longer duration of illness. Paired with noninvasive neuromodulation interventions, functional neuroimaging with functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and simultaneous fMRI-EEG have shown changes in resting-state functional connectivity that correlate with symptom modulation, particularly in the posterior default mode network. Reduced parieto-occipital connectivity with the entorhinal cortex and reduced long-range fronto-parieto-occipital connectivity correlate with symptom improvement. Though there is a general theme of desynchronization correlating with reduced MdDS symptoms, the prediction of optimal stimulation parameters for noninvasive brain stimulation in individuals with MdDS remains a challenge due to the large parameter space. However, the pairing of functional neuroimaging and noninvasive brain stimulation can serve as a probe into the biological underpinnings of MdDS and iteratively lead to optimal parameter space identification.

Introduction: Mal de Debarquement Syndrome (MdDS) is a poorly understood neurological disorder affecting mostly perimenopausal women. MdDS has been hypothesized to be a maladaptation of the vestibulo-ocular reflex, a neuroplasticity disorder, and a consequence of neurochemical imbalances and hormonal changes. Our hypothesis considers elements from these theories, but presents a novel approach based on the analysis of functional loops, according to Systems and Control Theory.Hypothesis: MdDS is characterized by a persistent sensation of self-motion, usually occurring after sea travels. We assume the existence of a neuronal mechanism acting as an oscillator, i.e., an adaptive internal model, that may be able to cancel a sinusoidal disturbance of posture experienced aboard, due to wave motion. Thereafter, we identify this mechanism as a multi-loop neural network that spans between vestibular nuclei and the flocculonodular lobe of the cerebellum. We demonstrate that this loop system has a tendency to oscillate, which increases with increasing strength of neuronal connections. Therefore, we hypothesize that synaptic plasticity, specifically long-term potentiation, may play a role in making these oscillations poorly damped. Finally, we assume that the neuromodulator Calcitonin Gene-Related Peptide, which is modulated in perimenopausal women, exacerbates this process thus rendering the transition irreversible and consequently leading to MdDS.Conclusion and Validation: The concept of an oscillator that becomes noxiously permanent can be used as a model for MdDS, given a high correlation between patients with MdDS and sea travels involving undulating passive motion, and an alleviation of symptoms when patients are re-exposed to similar passive motion. The mechanism could be further investigated utilizing posturography tests to evaluate if subjective perception of motion matches with objective postural instability. Neurochemical imbalances that would render individuals more susceptible to developing MdDS could be investigated through hormonal profile screening. Alterations in the connections between vestibular nuclei and cerebellum, notably GABAergic fibers, could be explored by neuroimaging techniques as well as transcranial magnetic stimulation. If our hypothesis were tested and verified, optimal targets for MdDS treatment could be found within both the neural networks and biochemical factors that are deemed to play a fundamental role in loop functioning and synaptic plasticity.

The aim of the descriptive study is to determine the factors affecting the postoperative sleep quality and Mal de debarquement is a sickness of disembarkation in which habituation to background rhythmic motion becomes resistant to readjustment to stable conditions, resulting in an illusory perception of self-movement typically described as rocking, bobbing, and swaying. It is commonly seen in the female gender. This condition, experienced by most sailors, usually resolves within 24 hours. However, in some people, this illusion of movement persists for weeks, months, or even years. Neuroimaging studies on individuals with this syndrome have seen changes in brain metabolism and functional brain connections, suggesting that the problem is in the brain, not the inner ear. As a result of these changes in the brain, the brain can adapt to an unusual move, but after the movement stops, the individual cannot adapt to the new situation. The history of the patient is very important as there is no specific test for the diagnosis of the disease. Vestibular tests and radiological imaging methods are used to exclude other causes of symptoms. There is no single highly effective approach to the treatment of the disease. Some drugs prescribed as standard are noted to have a weak effect in reducing symptoms. Some promising treatment methods with small sample sizes include the use of neuromodulation methods such as vestibular rehabilitation, optokinetic stimulation, use of benzodiazepines, and repetitive transcranial magnetic stimulation. The aim of this study is to review mal debarquement syndrome, its causes, and current evidence-based treatment approaches., Mal de debarquement kelimesinin tam karşılığı karaya çıkma hastalığıdır. Bu terim başlangıçta su üzerinde gemi veya tekne ile yapılan seyahatin bir yan etkisi olarak hissedilen hareket yanılsaması şeklinde belirtilse de günümüzde uçak, otomobil, tren gibi ulaşım araçlarından sonra da görülebildiği bildirilmiştir. Çoğu denizcinin yaşadığı bu durum genellikle 24 saat içerisinde düzelir. Bununla birlikte, MdDS’de bu hareket yanılsaması haftalar, aylar, hatta yıllar boyunca devam eder. Sıklıkla kadın cinsiyette görülen bu sendroma sahip bireyler üzerinde yapılan nörogörüntüleme çalışmalarında bireylerin beyin metabolizmasında ve fonksiyonel beyin bağlantılarında değişiklikler meydana gelmiştir bu da sorunun iç kulakta değil beyinde olduğunu göstermektedir. Bu değişiklikler sonucunda beyin alışılmadık bir harekete uyum sağlayabilir ancak hareket durduktan sonra yeni duruma uyum gösteremez. Bunun sonucunda da sallantı hissiyle gelen baş dönmesi, denge kaybı, yorgunluk, ışığa karşı hassasiyet, anksiyete ve depresyon gibi semptomlar meydana gelebilir. Sendromun tanısı için özel bir test bulunmadığından hastanın hikayesi çok önemlidir. Semptomların diğer nedenlerini dışlamak için de vestibüler testler ve radyolojik görüntüleme yöntemleri kullanılmaktadır. Mal de debarquement sendromunun tedavisinde güçlü bir etkiye sahip tek bir yaklaşım bulunmamaktadır. Standart olarak reçete edilen bazı ilaçların semptomları azaltmada zayıf bir etkiye sahip olduğu belirtilmektedir. Küçük örneklem boyutlarıyla yapılan ancak umut vadeden bazı tedavi yöntemleri arasında, vestibüler rehabilitasyon, optokinetik stimülasyon, benzodiazepin kullanımı, tekrarlı transkraniyal manyetik stimülasyon gibi nöromodülasyon yöntemlerinin kullanımı yer almaktadır. Bu derlemenin amacı mal de debarquement sendromunu, sendromun oluşum mekanizmasını ve kanıta dayalı güncel tedavi yaklaşımlarını incelemektir.

Mal de Debarquement syndrome (MdDS) is composed of constant phantom sensations of motion, which are frequently accompanied by increased sensitivity to light, inability to walk on a patterned floor, the sensation of ear fullness, head pressure, anxiety, and depression. This disabling condition generally occurs in premenopausal women within 2 days after prolonged passive motion (e.g., travel on a cruise ship, plane, or in a car). It has been previously hypothesized that MdDS is the result of maladaptive changes in the polysynaptic vestibulo-ocular reflex (VOR) pathway called velocity storage. Past research indicates that full-field optokinetic stimulation is an optimal way to activate velocity storage. Unfortunately, such devices are typically bulky and not commonly available. We questioned whether virtual reality (VR) goggles with a restricted visual field could effectively simulate a laboratory environment for MdDS treatment. A stripes program for optokinetic stimulation was implemented using Google Daydream Viewer. Five female patients (42 ± 10 years; range 26–50), whose average MdDS symptom duration was 2 months, participated in this study. Four patients had symptoms triggered by prolonged passive motion, and in one, symptoms spontaneously occurred. Symptom severity was self-scored by patients on a scale of 0–10, where 0 is no symptoms at all and 10 is the strongest symptoms that the patient could imagine. Static posturography was obtained to determine objective changes in body motion. The treatment was considered effective if the patient's subjective score improved by at least 50%. All five patients reported immediate improvement. On 2-month follow-ups, symptoms returned only in one patient. These data provide proof of concept for the limited-visual-field goggles potentially having clinical utility as a substitute for full-field optokinetic stimulation in treating patients with MdDS in clinics or via telemedicine.

Mal de debarquement syndrome (MdDS) is a disorder of persistent vertigo characterized by a feeling of oscillation such as rocking, bobbing, or swaying. It is triggered by passive motion, typically by exposure to water, air, or land transportation. This syndrome affects middle-aged individuals who are predominantly women. MdDS presents as a balance disorder that carries significant risk of morbidity due to both the direct effects of balance impairment and associated symptoms of fatigue, cognitive slowing, and visual motion intolerance. The Barany Society will be publishing criteria for diagnosing persistent MdDS. In addition, more insight has been gained into the pathophysiology of MdDS, with current hypotheses pointing to a cerebral and cerebellar basis. Treatments have expanded beyond medication trials, and now include the use of noninvasive brain stimulation and readaptation of the vestibulo-ocular reflex. [ABSTRACT FROM AUTHOR]

Background. Mal de Debarquement syndrome (MdDS) is a rare neuro-otologic disorder that mainly appears for middle-aged women and occurs after long-term passive motion (flight by plane, cruise). The syndrome symptoms can be persistent dizziness, sensation of rocking, unsteadiness, and disequilibrium. The syndrome diagnostics is complicated because there is no instrumental examination that could help to diagnose disorder thus neuro-otological examination is non-informative. The diagnosis is based on anamnesis, therefore, MdDS is often undiagnosed or inappropriate diagnosis is determined. To the knowledge of the authors, there are no publications on this syndrome in the Lithuanian language. Therefore, the aim of this article is to introduce this syndrome to Lithuanian doctors by presenting cases diagnosed in Lithuania and diagnostic criteria as well as by reviewing information published in the literature. Methods. Two clinical cases are described. Mal de Debarquement syndrome was diagnosed for two middle-aged women after air travel. Both women complained of sudden dizziness after the trip, however, neuro-otological examination had not revealed any pathology. In the literature review, 21 articles are overviewed describing the Mal de Debarquement syndrome. Results. Diagnostic criteria that helped to diagnose the Mal de Debarquement syndrome in 2016 are presented. A diagnostically significant feature of MdDS is a reduction in symptoms after the patient returns to passive motion. MdDS is often accompanied by anxiety and depression. Research shows that stress-reducing therapy, medications for migraine prophylactic, and lifestyle changes are effective in reducing symptoms and improving the quality of life. Conclusions. MdDS is still a rarely diagnosed disorder in many countries. Clinical symptoms and history of long-term passive motion is especially important for the diagnosis. Neurootological examination is required for differential diagnosis from other clinically similar diseases.

Introduction: Mal de Debarquement Syndrome (MdDS) is a neurological disorder which affects the vestibular system pathways, manifesting as a constant sensation of movement in the form of rocking, bobbing, or swaying. The mechanism of MdDS is poorly understood and there is a lack of awareness amongst medical professionals about the condition. This study aimed to examine treatments and symptom management strategies used by MdDS patients and evaluate their self-reported effectiveness.Method: Motion-Triggered and Spontaneous/Other onset MdDS patients responded to a set of comprehensive questions as a retrospective survey regarding epidemiological details, diagnostic procedures, onset, and symptom triggers, hormonal influences as well as treatments and symptom management strategies used to reduce symptoms. The Motion-Triggered questionnaire was made available through Survey Monkey and the Spontaneous/Other Onset questionnaire through Qualtrics. The link for each questionnaire was made available on online MdDS support groups and on various research websites. Descriptive statistics were used for epidemiological data and Pearson's Chi Square tests were used for comparisons between and within both subtype groups.Results: A total of 370 patients participated in the surveys, with 287 valid responses collected for the section regarding treatment and symptom management strategies. The success of the treatments and symptom management strategies did not vary between subtypes Benzodiazepines/Antidepressants were reported as being most beneficial in reducing symptoms in both groups.Conclusion: This was the first attempt to evaluate the reported success of treatments and symptom management strategies in MdDS patients by assessing the patients' perceived helpfulness. The treatments and symptom management strategies reported to be the most helpful in managing and/or reducing symptoms are proposed to be effective due to their stress-reducing capacities. We hope this study will broaden MdDS awareness and that this study will increase patient knowledge regarding treatments and symptom management strategies that other patients found helpful.

Introduction: Mal de Debarquement Syndrome (MdDS) is a condition characterized by a perception of self-motion in the absence of a stimulus, with two onset types: Motion-Triggered and Spontaneous. Currently, the pathophysiology is unknown and consequently, the therapeutic options are limited. One proposed treatment protocol, developed by Dai and colleagues is based on optokinetic stimulation, which aims to re-adapt the vestibular ocular reflex. This study aimed to reproduce the treatment protocol developed by Dai and colleagues and to assess if a placebo effect is present in the treatment protocol and lastly, aimed to further investigate the treatment on MdDS patient outcomes.Method: Twenty-five MdDS patients (13 Motion-Triggered and 12 Spontaneous) were exposed to 5 consecutive days of optokinetic treatment (consisting of exposure to optokinetic stimuli with head movements). Eleven of these 25 patients were also exposed to 2 days of a sham treatment prior to the OKN treatment. Posturography measurements and reported symptoms [e.g., using the visual analog scale (VAS)] of patients were assessed throughout the treatment. Posturography data of the patients was compared with the data of 20 healthy controls.Results: No placebo effect was recorded with any changes in postural data and VAS scale. After the optokinetic treatment, a significant improvement in postural control was observed in 48% of patients, of whom 70% were of the Motion-Triggered subtype (p-values: Area under the Curve—Anterior Posterior < 0.001; Area under the Curve—Medio Lateral p < 0.001, Confidence Ellipse Area (CEA) < 0.001, Velocity < 0.001).Conclusion: The protocol was effective in approximately half of the MdDS patients that took part in the study, with no placebo effect recorded. The Motion-Triggered group responded better to treatment than the Spontaneous group. In addition to this, this study indicates that the greatest postural changes occur within the first 3 days of treatment, suggesting that a shorter protocol is possible. Overall, these findings support what was previously observed in Dai's studies, that optokinetic stimulation can reduce and ease self-motion perception in those with MdDS. Thus, validating the reproducibility of this protocol, suggesting that a consistent and uncomplicated implementation across treatment centers is possible.

Introduction: Mal de Debarquement Syndrome (MdDS) is the rare condition of enduring rocking sensations and subjective unsteadiness following a lengthy exposure to passive motion. The pathogenesis of MdDS is unknown and the available treatment is limited. Here, we developed an experimental model of MdDS that may facilitate systematic inquiry of MdDS pathophysiology and the development of prevention or treatment strategies for this condition. Methods: In an initial series of pilot experiments, suitable stimulation devices and conditions were evaluated. The final paradigm consisted of a low-frequency oscillatory motion stimulation, simultaneously deployed as roll and pitch rotation as well as heave on a six-degrees-of-freedom motion platform. Twelve healthy participants were stimulated under this condition for 30 min during free stance. Aftereffects with respect to rocking sensations and posturographic sway were monitored up to 60 min post-stimulation and compared to an initial pre-stimulation assessment as well as to posturographic recordings of spontaneous sway in ten patients with MdDS. Results: Motion stimulation consistently evoked MdDS-like rocking sensations and postural alterations that lasted up to 45 min after cessation of passive motion exposure. Body sway alterations were most pronounced in anterior–posterior dimension during standing with eyes closed and primarily characterized by a distinct peak in the low-frequency sway spectrum close to stimulation frequency. These postural aftereffects further closely resembled spontaneous oscillatory low-frequency sway observed in patients with MdDS. Conclusion: Subsequent neurophysiological and imaging examinations are required to investigate whether the model of transient, experimental MdDS actually shares a common substrate with the enduring pathological condition of MdDS.

Introduction: Mal de Debarquement Syndrome (MdDS) is a condition characterized by a sensation of motion in the absence of a stimulus, which presents with two subtypes depending on the onset: Motion-Triggered, and Spontaneous or Non-Motion Triggered. MdDS predominantly affects women around 40-50 years of age and a high number of patients report associated disorders, such as migraine and depression. The pathophysiology of MdDS is unclear, as is whether there are predisposing factors that make individuals more vulnerable to developing the condition. Hormonal changes in women similarly to what observed in migraineous patients, as well as depression disorder, have been examined as potential key factors for developing MdDS. Studies on migraine and depression have revealed correlations with hormonal fluctuations in females as well as aberrant levels of some key neurotransmitters such as Gamma-Aminobutyric Acid (GABA) and inflammatory neuropeptides like Calcitonin Gene-Related Peptide (CGRP). Consequently, this manuscript aims to propose a new hypothesis on the predisposing factors for MdDS and a new concept that could contribute to the understanding of its pathophysiology.New Hypothesis: Recent findings have demonstrated a role for hormonal influences in MdDS patients, similar to previous observations in patients with depression and migraine. We hypothesize the involvement of gonadal hormones and aberrant neurotransmitter levels, including the GABAergic and serotonergic systems, in MdDS pathophysiology. Our theory is that certain individuals are more vulnerable to develop MdDS during specific gonadal hormonal phases. Furthermore, we hypothesize that it may be possible to identify these individuals by measurement of an existing imbalance of these neurotransmitters or inflammatory neuropeptides like CGRP.Further Evaluation Of the Hypothesis: According to one theory, MdDS is considered as a maladaptation of the Vestibular Ocular Reflex (VOR) and velocity storage. When considering this theory, it is essential to highlight that the brainstem nuclei involved in the VOR and the velocity storage include GABAb sensitive neurons, which appear to produce inhibitory control of velocity storage. Responses of these GABAb sensitive neurons are also modulated by CGRP. Thus an alteration of the GABAergic network by imbalances of inhibitory neurotransmitters or CGRP could influence signal integration in the velocity storage system and therefore be directly involved in MdDS pathophysiology.Consequence Of the Hypothesis and Future Studies: A hormonal and neurotransmitter imbalance may act to predispose individuals in developing MdDS. Future studies should focus on the hormonal influences on neurotransmitters (e.g. GABA) and on the trial of CGRP antagonist drugs for the treatment of MdDS patients. [ABSTRACT FROM AUTHOR]- Published

- Abstract
To determine intrinsic functional connectivity (IFC) related to symptom changes induced by rTMS in mal de debarquement syndrome (MdDS), a motion perceptual disorder induced by entrainment to oscillating motion. Twenty right-handed women (mean age: 52.9 ± 12.6 years; mean duration illness: 35.2 ± 24.2 months) with MdDS received five sessions of rTMS (1 Hz right DLPFC, 10 Hz left DLPFC) over consecutive days. High-density (128-channel) resting-state EEG were recorded prior to and following treatment sessions and analyzed using a group-level independent component (IC) analysis. IFC between 19 ICs was quantified by inter-IC phase coherence (ICPC) in six frequency bands (delta, theta, low alpha, high alpha, beta, gamma). Correlational analyses between IFCs and symptoms were performed. Symptom improvement after rTMS was significantly correlated with (1) an increase in low alpha band (8-10 Hz) IFC but a decrease of IFC in all other bands, and (2) high baseline IFC in the high alpha (11-13 Hz) and beta bands (14-30 Hz). Most treatment related IFC changes occurred between frontal and parietal regions with a linear association between the degree of symptom improvement and the number of coherent IFC changes. Frequency band and region specific IFC changes correlate with and can predict symptom changes induced by rTMS over DLPFC in MdDS. MdDS symptom response correlates with high baseline IFC in most frequency bands. Treatment induced increase in long-range low alpha IFC and decreases in IFC in other bands as well as the proportion of coherent IFC changes correlate with symptom reduction. [ABSTRACT FROM AUTHOR]

One proposed treatment protocol, developed by Dai and colleagues is based on optokinetic stimulation, which aims to re-adapt the vestibular ocular reflex. This study aimed to reproduce the treatment protocol developed by Dai and colleagues and to assess if a placebo effect is present in the treatment protocol and lastly, aimed to further investigate the treatment on MdDS patient outcomes. Method: Twenty-five MdDS patients (13 Motion-Triggered and 12 Spontaneous) were exposed to 5 consecutive days of optokinetic treatment (consisting of exposure to optokinetic stimuli with head movements). Eleven of these 25 patients were also exposed to 2 days of a sham treatment prior to the OKN treatment. Posturography measurements and reported symptoms [e.g., using the visual analog scale (VAS)] of patients were assessed throughout the treatment. Posturography data of the patients was compared with the data of 20 healthy controls. Results: No placebo effect was recorded with any changes in postural data and VAS scale. After the optokinetic treatment, a significant improvement in postural control was observed in 48% of patients, of whom 70% were of the Motion-Triggered subtype (p -values: Area under the Curve—Anterior Posterior < 0.001; Area under the Curve—Medio Lateral p < 0.001, Confidence Ellipse Area (CEA) < 0.001, Velocity < 0.001). Conclusion: The protocol was effective in approximately half of the MdDS patients that took part in the study, with no placebo effect recorded. The Motion-Triggered group responded better to treatment than the Spontaneous group. In addition to this, this study indicates that the greatest postural changes occur within the first 3 days of treatment, suggesting that a shorter protocol is possible. Overall, these findings support what was previously observed in Dai's studies, that optokinetic stimulation can reduce and ease self-motion perception in those with MdDS. Thus, validating the reproducibility of this protocol, suggesting that a consistent and uncomplicated implementation across treatment centers is possible. [ABSTRACT FROM AUTHOR]

- Abstract
Background. Mal de Debarquement syndrome (MdDS) is a rare neuro-otologic disorder that mainly appears for middle-aged women and occurs after long-term passive motion (flight by plane, cruise). The syndrome symptoms can be persistent dizziness, sensation of rocking, unsteadiness, and disequilibrium. The syndrome diagnostics is complicated because there is no instrumental examination that could help to diagnose disorder thus neuro-otological examination is non-informative. The diagnosis is based on anamnesis, therefore, MdDS is often undiagnosed or inappropriate diagnosis is determined. To the knowledge of the authors, there are no publications on this syndrome in the Lithuanian language. Therefore, the aim of this article is to introduce this syndrome to Lithuanian doctors by presenting cases diagnosed in Lithuania and diagnostic criteria as well as by reviewing information published in the literature. Methods. Two clinical cases are described. Mal de Debarquement syndrome was diagnosed for two middle-aged women after air travel. Both women complained of sudden dizziness after the trip, however, neuro-otological examination had not revealed any pathology. In the literature review, 21 articles are overviewed describing the Mal de Debarquement syndrome. Results. Diagnostic criteria that helped to diagnose the Mal de Debarquement syndrome in 2016 are presented. A diagnosti cally significant feature of MdDS is a reduction in symptoms after the patient returns to passive motion. MdDS is often accompanied by anxiety and depression. Research shows that stress-reducing therapy, medications for migraine prophylactic, and lifestyle changes are effective in reducing symptoms and improving the quality of life. Conclusions. MdDS is still a rarely diagnosed disorder in many countries. Clinical symptoms and history of long-term passive motion is especially important for the diagnosis. Neuro-otological examination is required for differential diagnosis from other clinically similar diseases. [ABSTRACT FROM AUTHOR]

IntroductionMal de Debarquement Syndrome (MdDS) is a condition characterized by a persistent perception of self-motion, in most cases triggered from exposure to passive motion (e.g., boat travel, a car ride, flights). Patients whose onset was triggered in this way are categorized as Motion-Triggered (MT) subtype or onset group. However, the same syndrome can occur spontaneously or after non-motion events, such as childbirth, high stress, surgery, etc. Patients who were triggered in this way are categorized as being of the Spontaneous/Other (SO) subtype or onset group. The underlying pathophysiology of MdDS is unknown and there has been some speculation that the two onset groups are separate entities. However, despite the differences in onset between the subtypes, symptoms are parallel and a significant female predominance has been shown. To date, the role of gonadal hormones in MdDS pathophysiology has not been investigated. This study aimed to evaluate the hormonal profile of MdDS patients, the presence of hormonal conditions, the influence of hormones on symptomatology and to assess possible hormonal differences between onset groups. In addition, the prevalence of migraine and motion sickness and their relation to MdDS were assessed.MethodRetrospective online surveys were performed in 370 MdDS patients from both onset groups. Data were analyzed using Fisher’s exact test or Fisher-Freeman-Hanlon exact test. When possible, data were compared with normative statistical data from the wider literature.ResultsFrom the data collected, it was evident that naturally cycling female respondents from the MT group were significantly more likely to report an aggravation of MdDS symptoms during menses and mid-cycle (p

BackgroundThere has been increasing awareness that post-motion triggered rocking self-vertigo can last for months or years, a disorder known as Mal de Debarquement Syndrome (MdDS). A similar feeling of oscillating self-motion can occur without a motion trigger in some individuals, leading to controversy about whether motion triggered (MT) and non-motion triggered (non-MT) symptoms ultimately represent the same disorder.

Sex distribution (81% female) and age of onset (mean 43.4 ± 12.2 years MT; 42.1 ± 15.2 years non-MT) were comparable between MT and non-MT MdDS (p > 0.05). Mean duration of illness was significantly longer in the non-MT group (82.8 ± 64.2 months) than the MT group (35.4 ± 46.4 months) (p 50% individuals with a positive response).

Recognizing clinical features of MdDS subtypes may allow for better tailoring of therapy and potentially serve as classification criteria for new clinical designations.

Mal de debarquement syndrome (MdDS) is a neurological condition typically characterized by a sensation of motion, which in most cases manifests after disembarking from a vehicle (e.g., boat, plane, and car). However, the same symptoms can also occur spontaneously. Two main theories of the pathophysiology of MdDS are briefly summarized here. In this perspective, we aimed to report the most recent findings on neuroimaging studies related to MdDS, as well as to suggest further potential research questions that could be addressed with the use of neuroimaging techniques. A detailed analysis of previous work on MdDS has led to five main research questions that could be addressed in new neuroimaging studies. Furthermore, in this perspective, we propose new stepping-stones to addressing critical research questions related to MdDS and its pathophysiology. We propose considerations for new studies, as well as a detailed analysis of the current limitations and challenges present when studying MdDS patients. We hope that our examination of the nuances of MdDS as a neurological disorder will contribute to more directed research on this topic.

Data were analyzed using Fisher's exact test or Fisher-Freeman-Hanlon exact test. When possible, data were compared with normative statistical data from the wider literature. Results: From the data collected, it was evident that naturally cycling female respondents from the MT group were significantly more likely to report an aggravation of MdDS symptoms during menses and mid-cycle (p < 0.001). A few preliminary differences between the onset groups were highlighted such as in regular menstrual cycling (p = 0.028), reporting menses during onset (p < 0.016), and migraine susceptibility after onset (p = 0.044). Conclusion: These results demonstrate a potential relation between hormone fluctuations and symptom aggravation in the MT group. This study is an important first step to suggest a hormonal involvement in the pathophysiology of MdDS and provides a base for further hormonal investigation. Future prospective studies should expand upon these results and explore the implications for treatment. [ABSTRACT FROM AUTHOR]

Mean duration of illness was significantly longer in the non-MT group (82.8 ± 64.2 months) than the MT group (35.4 ± 46.4 months) (p < 0.001). There was no correlation between trigger type and age of onset or duration of illness for MT MdDS. Improvement with re-exposure to motion (driving) was typical for both (MT = 89%, non-MT = 64%), but non-MT individuals more frequently had symptoms exacerbated with motion (MT = 0%; non-MT = 10%). Peri-menstrual and menstrual worsening of symptoms was typical in both MT and non-MT MdDS (each 71%). Both MT and non-MT MdDS exhibited a higher population baseline prevalence of migraine (23% and 38%, respectively). Benzodiazepines and SSRI/SNRIs were helpful in both subtypes of MdDS (>50% individuals with a positive response). Physical therapy was modestly helpful in the MT (56%) subtype but not in non-MT (15%). Vestibular therapy made as many individuals worse as better in MT and none improved in the non-MT group.

Introduction: Mal de Debarquement Syndrome (MdDS) is a neurological condition typically characterized by a sensation of motion, that persists longer than a month following exposure to passive motion (e.g., cruise, flight, etc.). The most common form of MdDS is motion triggered (MT). However, recently it has been acknowledged that some patients develop typical MdDS symptoms without an apparent motion trigger. These cases are identified here as spontaneous or other onset (SO) MdDS. This study aimed to address similarities and differences between the MdDS subtypes. Diagnostic procedures were compared and extensive diagnostic guidelines were proposed. Second, potential triggers and associated psychological components of MdDS were revealed.Methods: This was a retrospective online survey study for MT and SO MdDS patients. Participants were required to respond to a set of comprehensive questions regarding epidemiological details, as well as the diagnostic procedures and onset triggers.Results: There were 370 patients who participated in the surveys. It is indicated that MdDS is often misdiagnosed; more so for the SO group. In addition to the apparent self-motion, both groups reported associated levels of stress, anxiety and depression.Discussion: It appears at present that both MdDS subtypes are still poorly recognised. This was the first attempt to evaluate the diagnostic differences between MdDS subtypes and to propose a set of comprehensive diagnostic guidelines for both MdDS subtypes. In addition, the current research addressed that associated symptoms such as stress, anxiety and depression should also be considered when treating patients. We hope this study will help the medical community to broaden their awareness and diagnostic knowledge of this condition. [ABSTRACT FROM AUTHOR]

Mal de Debarquement syndrome (MdDS), also known as disembarkment syndrome, is a benign neurological condition characterized by a feeling of rocking, bobbing, or swaying, usually presenting after an individual has been exposed to passive motion as from being on a cruise, long drive, turbulent air travel, or train. Clinical awareness about this condition is limited, as is research; thus, many patients go undiagnosed. In this case report, the authors describe a case of a severe headache as a major presenting symptom of MdDS in a 46-year-old woman who eventually attained full resolution of symptoms. This report aims to highlight this unique presentation and make practitioners more aware of the cardinal clinical features, to assist in prompt diagnosis of this disorder.

Individuals with mal de debarquement syndrome (MdDS) describe symptoms of swaying, rocking, and/or bobbing after sea or air travel. These symptoms may be because of maladaptation of the vestibulo-ocular reflex (VOR) to roll of the head during rotation. Dai and colleagues have developed a treatment paradigm that involves passive roll of the patient’s head while watching optokinetic stripes, resulting in adaption of the VOR and improvement of MdDS. The purpose of this case report is to describe replication of this treatment paradigm in a virtual reality environment with successful resolution of symptoms in two visits. A 39-year-old female reported swaying and rocking after returning from a 7-day cruise. The patient was treated with two sessions in a computer-assisted rehabilitation environment (CAREN). The patient canceled her third visit because of complete resolution of her symptoms. Her Global Rating of Change was +7 (on a 15-point scale of −7 to +7). She had returned to her prior level of function. This case report is the first to describe use of the CAREN for effective treatment of MdDS by replicating the treatment paradigm developed by Dai and colleagues.

We present diagnostic criteria for mal de débarquement syndrome (MdDS) for inclusion into the International Classification of Vestibular Disorders. The criteria include the following: 1] Non-spinning vertigo characterized by an oscillatory perception (‘rocking,’ ‘bobbing,’ or ‘swaying’) present continuously or for most of the day; 2] Onset occurs within 48 hours after the end of exposure to passive motion, 3] Symptoms temporarily reduce with exposure to passive motion (e.g. driving), and 4] Symptoms persist for >48 hours. MdDS may be designated as “in evolution,” if symptoms are ongoing but the observation period has been less than 1 month; “transient,” if symptoms resolve at or before 1 month and the observation period extends at least to the resolution point; or “persistent” if symptoms last for more than 1 month. Individuals with MdDS may develop co-existing symptoms of spatial disorientation, visual motion intolerance, fatigue, and exacerbation of headaches or anxiety. Features that distinguish MdDS from vestibular migraine, motion sickness, and persistent postural perceptual dizziness (PPPD) are reviewed. Motion-moderated oscillatory vertigo can also occur without a motion trigger, typically following another vestibular disorder, a medical illness, heightened psychological stress, or metabolic disturbance. Terminology for this non-motion triggered presentation has been varied as it has features of both MdDS and PPPD. Further research is needed into its phenomenological and biological relationship to MdDS, PPPD, and other vestibular disorders.

Absztrakt: A mal de débarquement szindróma ritka, vestibularis kórkép; legfőbb jellegzetessége az utazás, mozgó járművön (hajón, repülőn) tartózkodás után vagy spontán kialakuló tartós, hintázó, billegő egyensúlyzavar. A tünetek átmenetileg megszűnnek ismételt járműre szállás, például autóval utazás során. A krónikus fáradtság, szorongás, depresszió gyakran társuló panaszok. A diagnózis felállítása kihívást jelent, sokszor a páciensek maguk ismerik fel a betegséget. A pontos patofiziológia és definitív kezelési mód nem ismert, az optokineticus stimulációval végzett kezelés és a transcranialis mágneses stimuláció új terápiás perspektívát kínál. Tanulmányunkban 5 beteget mutatunk be, akiknél tartós, hónapokon át fennálló, folyamatos, imbolygó jellegű egyensúlyzavar alakult ki. Vizsgálatuk során normál belsőfül-funkciót vagy nem specifikus eltéréseket, továbbá negatív koponya mágneses rezonanciás vizsgálati leletet regisztráltunk. A kórlefolyás bemutatásán keresztül feltárjuk azokat a differenciáldiagnosztikai kérdéseket, amelyek segítségül szolgálnak a kórkép felismerésében. Ismertetjük az etiológiai háttérre vonatkozó elméleteket, a különböző kezelési módokkal elért nemzetközi eredményeket, továbbá a saját beteganyagunkon alkalmazott terápiás próbálkozásokat. A mal de débarquement szindróma diagnózisa kizáráson alapul, gyakran nem kerül felismerésre. Típusos kórtörténet, negatív vagy nem specifikus vizsgálati eredmények mellett érdemes megfontolni e kórkép diagnózisát. A korai diagnózis csökkentheti az orvosi vizitek és a nélkülözhető vizsgálatok számát. A gyakori diagnosztikus tévedés tovább fokozhatja a betegséggel társuló romló életminőséget, szorongást, depressziót. Orv Hetil. 2020; 161(20): 846–851.

Mal de debarquement syndrome (MdDS) is a disorder of persistent vertigo characterized by a feeling of oscillation such as rocking, bobbing, or swaying. It is triggered by passive motion, typically by exposure to water, air, or land transportation. This syndrome affects middle-aged individuals who are predominantly women. MdDS presents as a balance disorder that carries significant risk of morbidity due to both the direct effects of balance impairment and associated symptoms of fatigue, cognitive slowing, and visual motion intolerance. The Barany Society will be publishing criteria for diagnosing persistent MdDS. In addition, more insight has been gained into the pathophysiology of MdDS, with current hypotheses pointing to a cerebral and cerebellar basis. Treatments have expanded beyond medication trials, and now include the use of noninvasive brain stimulation and readaptation of the vestibulo-ocular reflex.
