Mal De Debarquement Syndrome: An Often Unrecognized and Unreported Condition.
Cureus
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.

Visually-induced dizziness is associated with sensitivity and avoidance across all senses.
Journal of neurology
BACKGROUND:Persistent postural perceptual dizziness (PPPD) is a common chronic condition presenting in neurology and neuro-otology clinics. Symptoms lie on a spectrum in the general population. The cause is unknown and thought to involve interactions between visual and vestibular systems, but symptoms also correlate with anxiety and migraine. OBJECTIVE:To test whether PDDD symptoms are associated with reported differences in other senses (touch, hearing, smell and taste); to investigate possible mediation via anxiety or migraine; to discover the proportion of variance accountable to these non-vestibular factors. METHODS:We measured self-report multisensory sensitivity, anxiety, visual difficulties, visual discomfort and migraine in patients with PPPD (N = 29) and a large general population cohort (N > 1100). We used structural equation modelling to examine relationships between the factors using a step-wise approach. RESULTS:We found increased self-reported over-sensitivity in sensory domains beyond vision and balance in both patients with PPPD and non-clinical participants with more PPPD symptoms. SEM analysis revealed that anxiety partly, but not wholly, mediated this relationship. Adding visual difficulties and visual discomfort to the model allowed it to explain 50% of PPPD symptom variance. Most of the path coefficients and mediation effects in our model were unchanged between participants with and without migraine. CONCLUSIONS:Our findings support the idea that PPPD is a complex neurological condition that includes broad perceptual factors, and may suggest that some brains are predisposed to generalised cross-modal sensory-overload. This may give rise to vulnerability to severe PPPD should a vestibular insult occur.

[Vertigo, a Driver's Licence with and without Permission to Drive: Are the Current Guidelines Justified?]
Huppert Doreen,Brandt Thomas
Laryngo- rhino- otologie
This article critically discusses the current assessment guidelines valid since 2014 which must be applied to determine the driving aptitude of patients with dizziness and balance disorders (in the official document called "disorders of the sense of balance"). With all due respect for the meticulous work of the expert commission who established the guidelines - the likes of which are not known anywhere else - we consider their revision imperative. On the basis of our many years of experience in the German Center for Dizziness and Balance Disorders of the LMU Munich it is our opinion that these restrictions are too strict and the required dizziness-free intervals are too long.The guidelines now stipulate the following for drivers with a group 1 driving licence ("private"):1) Patients with Meniere's disease (attacks without prodromes) must have had no attacks for 2 years before it is possible to drive a car again.2) Patients with vestibular migraine without prodromes must not have had any attacks for 3 years.The following stipulations hold for drivers with a group 1 and group 2 driving licence ("professional driver"):3) Patients with bilateral vestibulopathy as a rule are considered to have a driving disability, likewise4) Patients with central vestibular forms of vertigo, e. g., oculomotor disorders like downbeat and upbeat nystagmus syndromes are also as a rule regarded as having a driving disability.5) Patients with functional (psychogenic) forms of dizziness (e. g., phobic postural vertigo) who have a group 1 driving licence are considered to have a driving disability if dizziness occurs while driving. Those with a group 2 driving licence are in general considered to have a driving disability. However, many patients with episodic or chronic dizziness have such minor symptoms that their driving fitness is not relevantly impaired or if they do have an attack, they are able to stop driving in a controlled manner. In contrast, the restrictions on other illnesses that are accompanied by attack-like disorders of cognition and consciousness like the epilepsies are less strict. Depending on the type of attack or its trigger, the attack-free interval for such patients with a group 1 driving licence amounts to 3 months up to 1 year, although they clearly are not fit to drive during an attack.

The Influence of Migraine on Driving: Current Understanding, Future Directions, and Potential Implications of Findings.
Headache
OBJECTIVE:To review the published findings relevant to migraine and driving performance, with an intent to encourage discussion on research which may broaden understanding in this area and help educate healthcare providers and their patients. BACKGROUND:Motor vehicle crashes result in more than 35,000 deaths and more than 2 million injuries annually in the United States. Migraine is one of the most prevalent diseases in the world, and many symptoms associated with migraine attacks have the potential to negatively influence driving ability. METHODS:We reviewed the published findings related to migraine and driving performance. Study findings relevant to symptoms of migraine and their potential effect on driving were also reviewed. This required a more expansive exploration of the literature beyond migraine, for example, review of the literature relating to the effect of pain, sleepiness, visual disturbances, or vertigo on driving. Finally, the potential effects of treatment for migraine on driving were reviewed. RESULTS:Literature on the effect of migraine on driving performance is sparse and, in general published studies on the topic have a number of limitations. Based on review of the literature pertaining to other disorders, it seems feasible that some symptoms occurring as part of the migraine attack could impact driving performance, although formal study in this area is lacking. Many of the approved treatments for migraine have the potential to impact driving, yet this has not been specifically studied, and the extent to which these risks are communicated to patients is not clear. CONCLUSION:The impact of migraine on driving performance has been largely neglected, with few studies specifically designed to address the topic, and relevant studies were generally small with limited control of confounders. This area requires more focus, given a potential for impact on road safety.

Vestibular Physical Therapy and Fall Risk Assessment.
Carender Wendy J,Grzesiak Melissa,Telian Steven A
Otolaryngologic clinics of North America
Vestibular physical therapy (VPT) is a specialized form of evidence-based therapy designed to alleviate primary (vertigo, dizziness, imbalance, gait instability, falls) and secondary (deconditioning, cervical muscle tension, anxiety, poor quality of life, fear of falling/fear avoidance behavior) symptoms related to vestibular disorders. This article provides an overview of VPT, highlighting various exercise modalities used to treat a variety of vestibular disorders. Patient safety and fall prevention are paramount; therefore, fall risk assessment and treatment are also addressed.

Medical record prompts improve the frequency and documentation of dizziness and driving conversations in the ENT balance clinic.
The Journal of laryngology and otology
BACKGROUND:Driving capacity is affected by vestibular disorders and the medications used to treat them. Driving is not considered during medical consultations, with 92 per cent of patients attending a centre for dizziness not discussing it with the doctor. OBJECTIVE:To investigate if medical record prompts facilitate dizziness and driving conversations in ENT balance clinics. METHODS:A questionnaire was designed to reflect the current standards of practice and advice given regarding driving and dizziness during balance clinic consultations. RESULTS:Medical record prompts facilitated the improved frequency and recording of shared decision-making conversations about driving and dizziness in 98 per cent of consultations. CONCLUSION:This study highlights the benefits of medical record prompts for documented and accurate shared decision-making conversations surrounding dizziness, vertigo, vestibular conditions and driving. This potentially improves safety for all road users, and protects the patient and clinician in the event of road traffic accidents and medico-legal investigations.

Dizziness and Driving From a Patient Perspective.
van Leeuwen Roeland B,Schermer Tjard R,Colijn Carla,Bruintjes Tjasse D
Frontiers in neurology
People with dizziness may experience driving-related limitations. Few data are available about the impact of dizziness on driving. The aim of this study is to investigate the impact of dizziness on driving, factors related to impairment (age, gender, and type of diagnosis), and the potential consequences for patients' ability to work. We also investigated whether the patients expected and actually received information about their dizziness-related fitness to drive from their physician. A cross-sectional, observational study was conducted in the Apeldoorn Dizziness Centre, a tertiary care referral centre for patients with dizziness. A consecutive cohort of patients was asked to complete a study-specific questionnaire about driving. Between January 1, 2020, and December 20, 2020, 432 patients were included. Fifty-six percent of the patients in this group were female. The average age of patients was 58.3 years (SD 16). Overall, 191 of the 432 patients (44%) experienced limitations related to driving, and 40% of the patients who experienced limitations also experienced limitations to work related to their inability to drive. The subject of fitness to drive had not been discussed with their physician in 92% of the patients, and 24% of the whole patient group indicated that they would have liked to discuss this topic. The following factors, independently from each other, increased the chance of experiencing driving-related limitations: younger age, female sex, and the diagnosis of Meniere's disease. Dizzy patients, especially younger patients, women, and patients with Meniere's disease, regularly experience limitations related to driving, and this often means that they are unable to work. Driving is hardly ever discussed during a medical consultation. In our opinion, the topic of driving and dizziness should always be addressed during medical consultations in dizzy patients.
