MdD


Presentation

  • This article, the second in a 3-part series, presents information about Mal de Debarquement syndrome (MDD, also known as disembarkment sickness) and presents a case study of a patient who was relieved of MDD symptoms.[hearingreview.com]

Fatigue
  • The feeling of being in motion and dealing with the associated nausea, disorientation and fatigue that comes with MdDS can be debilitating for sufferers.[myphiladelphiadisabilitylawyer.com]
  • Manifestations begin shortly after the stimulus, persist for 6 months to years and may be associated with anxiety, fatigue and impaired cognition.[orpha.net]
  • Secondary symptoms of MdDS may include: Depression Feeling confused or having anxiety Fatigue Difficulty focusing Symptoms may subside when riding in a car or a train, but they may come back when you stop moving.[mercy.com]
  • Other common symptoms include fatigue, confusion, memory problems and a decrease in cognitive function.[kolblegal.com]
Swelling
  • One blustery, winter night I lay awake as my raft bounced up and down on colossal swells. Gripping the bed, I tried to stop resisting the motion, telling myself over and over again I wasn’t really in danger. Not an easy task.[liferaftmdds.com]

Nystagmus
  • Oscillating Vertical Nystagmus Weak oscillating vertical-nystagmus was present in 7 out of 16 subjects (Table 1 ).A typical example is shown in Figure 3. Head roll of 20 at 0.2 Hz elicited the nystagmus in darkness.[doi.org]

  • Rotation of the drum elicited optokinetic nystagmus, and it also produced a sense of self-rotation (circular vection). The direction of the sensed rotation was opposite to that of the direction of rotation of the visual field.[fauquierent.blogspot.com]
  • The trouble is I have never been on a cruise and my condition started with an acute spinning vertigo attack that left me with nystagmus which as far as I know is not associated with this particular condition.[dizzinessandvertigo.weebly.com]

Pendular Nystagmus
  • While the appearance of a rocking sensation as a result of adaptation might seem implausible, as it implies the initiation of an oscillating pattern, experimentally a pendular nystagmus lasting up to 60 minutes can be induced in rabbits by 24 hours of[doi.org]
Seizure

Workup

  • Overview The author explains the clinical presentation, pathophysiology, diagnostic workup, and management of mal de debarquement syndrome.[medlink.com]
  • An extensive workup, consisting of magnetic resonance imaging (MRI) brain (Figure 1 ), video-nystagmography (VNG), oculomotor testing, positional testing, and audiogram were all normal.[cureus.com]
  • Many had completed neurologic and otologic workups including MRIs. These studies were generally normal. Treatment Procedure The clinical treatment has been detailed in our previous study ( 1 ).[frontiersin.org]

Treatment

  • We will provide you with specific instructions if the home treatment is necessary when you return home. The home treatment is individually tailored based on the results of lab treatments.[labs.icahn.mssm.edu]
  • After treatment, the rhythmic oscillations present before the treatment disappeared.[doi.org]
  • The underlying neural mechanisms are unknown, and to date there have been no effective treatments for this condition.[ncbi.nlm.nih.gov]
  • Our treatment may not be effective if you do not stop benzo-medication three weeks prior to your treatment.[mdds.nyc]
  • Though not measured, the patient noted during treatment she was symptom free for the duration of every 4 min treatment session, including the initial trial of counterclockwise treatments.[academic.oup.com]

Prognosis

  • Prognosis Many people do feel unsteady for a few minutes but the symptoms of mal de debarquement syndrome can persist for more than thirty days and sometimes for years.[mddk.com]

Etiology

  • Objectives: To better define real de debarquement ('sickness of disembarkment') syndrome, to understand the etiology or mechanism of this disorder, and to seek better prevention and treatment options for this disorder.[scholars.northwestern.edu]
  • We undertook a patient survey to better define MDD, to understand the etiology or mechanism of this disorder, and to seek better prevention and treatment options.[doi.org]
  • These tests are important in excluding other etiologies for the patient’s symptoms. Standard Therapies Treatment MDD is very difficult to treat, with little effectiveness of most treatments.[rarediseases.org]

Epidemiology

  • The epidemiology of vestibular dysfunction in women with perimenopausal period. Crimean J Exp Clin Med (2013) 3 N(1–2):14–7. Google Scholar 18. Lempert T, Neuhauser H. Epidemiology of vertigo, migraine and vestibular migraine.[frontiersin.org]
  • Epidemiology The condition is thought to be under-reported in the medical literature. A study of 27 cases, conducted by Timothy C Hain in 1999, noted all but one patient to be female.[ipfs.io]
  • This could be due to the epidemiological characteristics of MdDS patients, as the average age of onset is in most cases occurring in the late 40s [ 10, 20 ].[future-science.com]

Pathophysiology

  • A new recent hypothesis has been formulated considering the two pathophysiological theories previously described [ 13, 19, 21, 25 ].[future-science.com]
  • Finally, we will discuss a differential diagnosis for the syndrome, insights into the possible pathophysiology, current treatments, and future directions in management. 2015 American Academy of Neurology View Full Text AAN Members: Sign in with your AAN[cp.neurology.org]
  • However, more research is needed to evaluate the actual effect of estrogen on MdDS pathophysiology.[frontiersin.org]

Prevention

  • Hence, preventing MDDS is also an area of active concern. Once again, possible prevention is largely speculative, but medications which diminish the response of the vestibular system may be useful.[checkorphan.org]
  • Preventing Occurrences of MDDS While MDDS usually eventually disappears, it also more often than not seems to return once a former MDDS sufferer takes another long boat or plane trip. Hence, preventing MDDS is also an area of active concern.[etete.com]
  • Objectives: To better define real de debarquement ('sickness of disembarkment') syndrome, to understand the etiology or mechanism of this disorder, and to seek better prevention and treatment options for this disorder.[scholars.northwestern.edu]
  • Prevention of MdDS Medications taken prior and during boat travel might prevent development of MdDS. According to Cha and others (2009), having migraine increases the probability of recurrent MdDS.[dizziness-and-balance.com]
  • In general, one might consider treatments aimed at preventing MDD and treatments aimed at ameliorating the effects of MDD once it has occurred. We know of no studies to date regarding prevention of MDD through medication.[doi.org]
