The relationship between dizziness and sleep: a review of the literature.

Background: The relation between vestibular disorders and (quality of) sleep is underexplored scientifically and the complex interactions between vestibular and sleep disorders are far from being well understood. Some studies have been conducted on the association between patients with vestibular disorders and (the occurrence of) sleep disorders, other studies have been published on the prevalence of dizziness complaints in patients with sleep disorders. The quality of sleep in patients with vestibular disorders generally receives little attention in clinical practice. Objective: To establish what is currently known about the mutual relationship between dizziness and sleep, and to assess whether or not there is evidence of causality with regard to this relationship. Methods: After systematically searching four literature database up until 1 April 2024, selected studies were summarized and evaluated through a (critical) review. Results: Ultimately, 42 studies were selected and evaluated. Patients with dizziness in general and patients with a specific vestibular disorder like Benign Paroxysmal Positional Vertigo, Vestibular Migraine, Meniere's disease, and vestibular hypofunction were significantly more likely to have sleep disorders than control groups. A causal relationship is not supported due to the nature of the studies. In patients with obstructive sleep apnea syndrome there were significantly more vestibular complaints, and more disorders in the vestibular system were identified. Conclusion: Dizziness complaints often co-exist with a sleep disorder. To what extent this sleep disorder influences dizziness is not clear. Paying attention to the quality of sleep in patients with a vestibular disorder seems to be important. In patients with OSAS, consideration should be given to vestibular complaints and dysfunction.

Risk Factors for Recurrence of Benign Paroxysmal Positional Vertigo: A Prospective Study.

OBJECTIVES: Benign paroxysmal positional vertigo (BPPV) can be treated successfully in most cases. However, recurrences are common. We aimed to prospectively investigate demographic and clinical risk factors for BPPV recurrence. Our second aim was to investigate whether seasonality affects recurrences. METHODS: We recruited adult Dutch patients presenting at our dizziness clinic with a diagnosis of definite or possible BPPV for a prospective observational study with 1-year follow-up. Factors collected from patient history and questionnaires were age, sex, ethnicity, previous treatment for BPPV, duration of BPPV symptoms, number of treatment sessions for the initial BPPV episode, the affected canal, recent head trauma, and a history of vestibular neuritis, Menière's disease, (vestibular) migraine, gout, diabetes mellitus, and chronic renal failure. Factors derived from blood samples were uric acid, glycated hemoglobin, and 25-hydroxyvitamin D. RESULTS: We included 139 subjects with a mean age of 65 (SD, 13) years, of whom 70% was female. A total of 48 subjects (34.5%) suffered from at least one recurrence during the 1-year follow-up. Independent risk factors for recurrence of BPPV were "multiple treatment sessions for the initial BPPV episode" (incidence rate ratio, 1.74; 95% confidence interval 1.06-2.85; p = 0.027) and history of gout (incidence rate ratio, 1.90; 95% confidence interval, 1.01-3.57; p = 0.045). CONCLUSION: One-third of patients presenting in a tertiary dizziness clinic develop at least one recurrence of BPPV within 1 year. Multiple treatment sessions and a history of gout are independent risk factors for recurrence.

Assessing risk of stroke after idiopathic sudden sensorineural hearing loss using data from general practice.

The cause of sudden sensorineural hearing loss (SSNHL) remains unknown in a significant number of cases, but vascular involvement in its pathophysiology has been proposed. Our study aimed to assess the incidence of stroke following idiopathic SSNHL (iSSNHL) and to evaluate associated cardiovascular risk factors and comorbidities. We extracted electronic medical record data from iSSNHL patients aged ≥ 50 years retrospectively from 84 general practices. Patients were matched for age, sex and general practice in a 1:4 ratio to controls. Primary outcome was the 5-years stroke risk following iSSNHL diagnosis. 480 iSSNHL cases could be matched to 1911 controls. The hazard ratio for iSSNHL compared with controls was 1.25 (95%CI 0.50-3.27; P = 0.646) for CVA (cerebrovascular accident) alone and 0.92 (95% CI 0.50-1.71; P = 0.804) for CVA and TIA (transient ischemic attack) combined. The hazard ratio for the interaction term between iSSNHL and age ≥ 60 years was 4.84 (95% CI 1.02-23.05; P = 0.048) for CVA and TIA combined. Patients with iSSNHL used antihypertensives and beta-blocking agents more frequently than controls (P = 0.006 and P = 0.022, respectively). In conclusion, no overall significant difference in the risk of stroke was observed, but the hazard ratio for stroke increased in iSSNHL patients aged 60 and older, suggesting potential vascular involvement in older subjects presenting with sudden sensorineural hearing loss.

Prospective diagnostic accuracy study of history taking and physical examination for adults with vertigo in general practice: study protocol.

INTRODUCTION: Vertigo is a prevalent and burdensome symptom. More than 80% of patients with vertigo are primarily treated by their general practitioner (GP) and are never referred to a medical specialist. Despite this therapeutic responsibility, the GP's diagnostic toolkit has serious limitations. All recommended tests lack empirical evidence, because a diagnostic accuracy study on vestibular disorders ('How well does test x discriminate between patients with or without target condition y?') has never been performed in general practice. The VERtigo DIagnosis study aims to fill this gap. METHODS AND ANALYSIS: We will perform a diagnostic accuracy study on vertigo of primary vestibular origin in general practice to assess the discriminative ability of history taking and physical examination. We will compare all index tests with a respective reference standard. We will focus on five target conditions that account for more than 95% of vertigo diagnoses in general practice: (1) benign paroxysmal positional vertigo, (2) vestibular neuritis, (3) Ménière's disease, (4) vestibular migraine (VM) and (5) central causes other than VM. As these five target conditions have a different pathophysiology and lack one generally accepted gold standard, we will use consensus diagnosis as a construct reference standard. Data for each patient, including history, physical examination and additional tests as recommended by experts in an international Delphi procedure, will be recorded on a standardised form and independently reviewed by a neurologist and otorhinolaryngologist. For each patient, the reviewers have to decide about the presence/absence of each target condition. We will calculate sensitivity, specificity, predictive values, likelihood ratios and diagnostic ORs, followed by decision rules for each target condition. ETHICS AND DISSEMINATION: The study obtained approval from the Vrije Universiteit Medical Center Medical Ethical Review Committee (reference: 2022.0817-NL83111.029.22). We will publish our findings in peer-reviewed international journals. TRIAL REGISTRATION NUMBER: ISRCTN97250704.

Course of Duration and Trigger Factors of Vertigo Attacks in Patients with Benign Recurrent Vertigo, Menière's Disease, or Vestibular Migraine.

INTRODUCTION: Benign recurrent vertigo (BRV), Menière's disease (MD), and vestibular migraine (VM) show many similarities with regard to the course of vertigo attacks and clinical features. In this paper, we elaborate on the decreasing frequency of vertigo attacks observed in a previous study from our group by exploring changes in the duration and trigger factors of vertigo attacks in patients with BRV, MD, or VM. METHODS: For this 3-year prospective cohort study in our tertiary referral center we recruited patients with a confirmed diagnosis of BRV, MD, or VM by a neurologist and otorhinolaryngologist in our center in 2015-2016. A study-specific questionnaire was used to assess the usual duration of vertigo attacks and their potential triggers every 6 months. Main outcome measures were changes in duration and trigger factors of vertigo attacks in the subgroups of patients with persisting attacks, which were analyzed using repeated measures logistic regression models. RESULTS: 121 patients were included (BRV: n = 44; MD: n = 43; VM: n = 34) of whom 117 completed the 3-year follow-up period and 57 (48.7%) kept reporting vertigo attacks at one more follow-up measurements. None of the diagnosis groups showed statistically significant shortening of attack duration at the subsequent annual follow-up measurements compared to baseline. At baseline, stress and fatigue being reported as triggers for attacks differed significantly between the three groups (stress: BRV 40.9%, MD 62.8%, VM 76.5%, p = 0.005; fatigue: BRV 31.0%, MD 48.8%, VM 68.8%, p = 0.003). In the VM group, a consistent reduction of stress and fatigue as triggers was observed up until the 24- and the 30-month follow-up measurements, respectively, with odds ratios (ORs) ranging from 0.15 to 0.33 (all p < 0.05). In the MD group, a consistent reduction of head movements as trigger was observed from the 24-month measurement onward (ORs ranging from 0.07 to 0.11, all p < 0.05). CONCLUSION: Our study showed no reduction in vertigo attack duration over time in patients with BRV, MD, and VM who remain to have vertigo attacks. In VM and MD patients with persisting vertigo attacks stress, fatigue and head movements became less predominant triggers for vertigo attacks.

Cardiovascular Risk Factors, Cerebral Small Vessel Disease, and Subsequent Risk of Stroke in Patients with Idiopathic Sudden Sensorineural Hearing Loss: Systematic Review and Meta-Analyses of the Current Literature.

Vascular involvement in the pathophysiology of idiopathic sudden sensorineural hearing loss (iSSNHL) has been previously proposed. The objective of this study was to perform a systematic review of the current literature and conduct meta-analyses to evaluate associations between cardiovascular risk factors, cerebral small vessel disease, and subsequent stroke after presentation with iSSNHL. Three systematic literature reviews and meta-analyses were conducted using PubMed, Embase, and CINAHL. All studies investigating associations between iSSNHL and the cardiovascular risk factors: body mass index (BMI), diabetes mellitus, hyperlipidemia, hypertension, medical history of myocardial infarction (MI), smoking, the degree of white matter hyperintensities, and incidence of stroke were included. Adhering to the PRISMA guidelines, two independent reviewers reviewed the articles and assessed risk of bias. The cardiovascular risk factors of abnormal BMI, diabetes, hypertension, total cholesterol, low-density lipoprotein cholesterol, and a medical history of MI were significantly associated with iSSNHL. The adjusted hazard ratio of a higher degree of white matter hyperintensities was 0.70 (95% CI 0.44, 1.12). Patients with iSSNHL showed a higher risk of stroke compared to controls, with hazard ratios ranging from 1.22 up to 4.08. Several cardiovascular risk factors are more frequently present in patients with iSSNHL than in the general population. The degree of white matter hyperintensities does not appear to be increased in patients with iSSNHL, while the risk of stroke following ISSNHL is increased. Prospective studies with larger study populations are needed to confirm the associations between generalized cardiovascular disease and iSSNHL and to assess whether these patients benefit from cardiovascular risk management to prevent future cardiovascular and cerebrovascular disease.

High prevalence of abdominal aortic aneurysm in older men with cerebrovascular disease: Evaluation of a local screening program.

Introduction: Patients with cerebrovascular disease may suffer from other vascular morbidities, such as abdominal aortic aneurysm (AAA). Previously, a high prevalence of AAA has been demonstrated in men 60 years of age and older who have experienced TIA or stroke. This report evaluates the results of a decade's operation of a local screening program for AAA in this selected neurologic population. Methods: Men aged ≥60 years and admitted to the neurology ward of a community-based hospital in the Netherlands from 2006 to 2017 with a diagnosis of TIA or stroke were selected for screening. The diameter of the abdominal aorta was assessed by abdominal ultrasonography. Patients with detected AAA were referred for evaluation by a vascular surgeon. Results: AAA was detected in 72 of 1,035 screened patients (6.9%). AAAs with a diameter of 3.0-3.9 cm accounted for 61.1% of the total aneurysms found; AAAs with a diameter of 4.0-5.4 cm accounted for 20.8% of the total; and large aneurysms with a diameter of ≥5.5 cm accounted for 18.1% of all aneurysms discovered. A total of 18 patients (1.7%) underwent elective aneurysm repair. Discussion: The detection rate of AAA in older men with cerebrovascular disease was roughly 5-fold the detection rate in known European screening programs in older men from the general population. The proportion of large AAAs (≥5.5 cm) was also substantially higher. These findings reveal a previously unknown co-morbidity in patients with cerebrovascular disease and may be helpful for cardiovascular management of this large group of neurologic patients. Current and future AAA screening programs may also benefit from this knowledge.

Cerebral Small Vessel Disease in Elderly Patients with Sudden Sensorineural Hearing Loss.

BACKGROUND: The cause of sudden sensorineural hearing loss (SSNHL) is uncertain in a significant number of patients. A vascular etiology has been proposed because SSNHL increases the risk of developing a stroke. Cardiovascular risk factors can cause cerebral small vessel disease (CSVD). The presence of CSVD in turn raises the risk of stroke. AIM: The aim of this study was to compare the presence of CSVD and cardiovascular risk factors in elderly patients with idiopathic SSNHL (iSSNHL) to a control cohort. METHOD: Patients with iSSNHL of 50 years and older were compared with a control cohort with patients suspected of trigeminal neuralgia or vestibular paroxysmia. The primary outcome was the difference in the number of white matter hyperintensities using the ordinal Fazekas scale. Secondary outcomes were the presence of brain infarctions on MRI and the difference in cardiovascular risk factors. RESULTS: In the SSNHL cohort, Fazekas score 2 was most frequently seen compared with Fazekas 1 in the control cohort. The distribution of Fazekas scores did not differ significantly. The sum of the Fazekas scores were 13,925 and 14,042 for iSSNHL and controls, respectively ( p = 0.908). Brain infarctions were seen in 8 patients with iSSNHL (n = 118) and in 13 patients in the control cohort (n = 118) ( p = 0.361). None of the cardiovascular risk factors were more frequently seen in the iSSNHL cohort. CONCLUSION: Patients with iSSNHL did not exhibit more CSVD on MRI than controls. This result is in contrast with previous literature demonstrating a higher risk of stroke in patients with iSSNHL than in controls. A prospective analysis with a larger study population is therefore warranted.

Cerebral Small Vessel Disease in Elderly Patients With Menière's Disease.

Background: Menière's disease (MD) is an inner ear disease characterized by vertigo attacks, progressive hearing loss, tinnitus, and the sensation of aural fullness. Although the exact pathophysiology of MD is unknown, endolymphatic hydrops is considered to be its histopathological hallmark. It has been suggested that endolymphatic hydrops results from lowered perfusion pressure due to cardiovascular comorbidity. Cardiovascular risk factors can cause cerebral small vessel disease (CSVD), visible on MRI. The presence of CSVD in turn raises the risk of developing a stroke. Objectives: This study aimed to compare the presence of CSVD and cardiovascular risk factors in elderly patients with MD to a control cohort. Methods: Patients diagnosed with MD, aged 50 years and older, were retrospectively reviewed and compared with a control cohort. The primary outcome was the difference in CSVD on MRI imaging, which was assessed by the number of white matter hyperintensities using the ordinal Fazekas scale. The secondary outcome was the presence of brain infarctions on MRI. Results: A total of 111 patients with MD were compared with a control cohort of 111 patients. No difference in the degree of white matter hyperintensities (P = 0.890) was found between the MD and control cohort. Brain infarctions were seen in 8 of 111 patients with MD and 14 of 111 patients from the control cohort (P = 0.261). Conclusion: CSVD is not more frequently visible on MRI in elderly patients with MD than in controls. This result does not support hypoperfusion-induced ischemia in the pathophysiology of MD.

Dizziness is a frequently occurring problem with a negative influence on quality of life. In this article, the most common causes of dizziness are discussed on the basis of practical questions from clinical practice. The importance of a structured anamnesis is reviewed. The clinical syndrome of benign paroxysmal positional vertigo and its treatment are covered extensively. Red flag symptoms of acute vestibular syndrome are specified, as well as symptoms that justify referral from primary to secondary care.

Cerebral Small Vessel Disease in Elderly Patients With Vestibular Neuritis.

Background: Acute audiovestibular loss is a neurotologic emergency of which the etiology is frequently unknown. In vestibular neuritis a viral genesis is expected, although there is insufficient evidence to support viruses as the only possible etiological factor. In sudden deafness, a vascular etiology has been proposed in elderly patients, since cardiovascular risk factors are more frequently present and a higher risk of developing a stroke was seen compared to the general population. So far, very little research has been carried out on vascular involvement in elderly patients with vestibular neuritis. Cardiovascular risk factors have a positive correlation with cerebral small vessel disease, visible as white matter hyperintensities, brain infarctions, microbleeds and lacunes on MRI. The presence of these characteristics indicate a higher risk of developing a stroke. Aim: We investigated whether elderly patients with vestibular neuritis have a higher prevalence of vascular lesions on MRI compared to a control cohort. Materials and Methods: Patients of 50-years and older, diagnosed with vestibular neuritis in a multidisciplinary tertiary referral hospital, were retrospectively reviewed and compared to a control cohort. The primary outcome was the difference in cerebral small vessel disease on MRI imaging, which was assessed by the number of white matter hyperintensities using the ordinal Fazekas scale. Secondary outcomes were the presence of brain infarctions on MRI and the difference in cardiovascular risk factors. Results: Patients with vestibular neuritis (N = 101) had a 1.60 higher odds of receiving a higher Fazekas score than the control cohort (N = 203) (p = 0.048), there was no difference in presence of brain infarctions (p = 1.0). Hyperlipidemia and atrial fibrillation were more common in patients experiencing vestibular neuritis. Conclusion: We found a positive correlation of white matter hyperintensities and VN which supports the hypothesis of vascular involvement in the pathophysiology of vestibular neuritis in elderly patients. Further prospective research is necessary to confirm this correlation.

Benign Recurrent Vertigo: The Course of Vertigo Attacks Compared to Patients With Menière's Disease and Vestibular Migraine.

Objective: To explore the course of vertigo attacks in patients with benign recurrent vertigo (BRV) as compared to patients with Menière's disease (MD) and vestibular migraine (VM). Study design: Prospective cohort study. Setting: Tertiary referral center. Patients: Adult patients who visited the Apeldoorn Dizziness Center between January 2015 and November 2016 and who were diagnosed with BRV, VM or MD. During 3 years participants were contacted every 6 months by telephone to complete a study-specific questionnaire. Main Outcome Measures: Vertigo attack frequency, use of medication, and Hospital Anxiety and Depression Scale (HADS). Results: The study population (n = 121) consisted of 44 patients with BRV, 34 with VM, and 43 with MD. For the total follow-up period no statistically significant differences between the three diagnosis groups were observed for being attack-free in the past 6 months: OR = 0.86 (95% CI 0.34-2.17; p = 0.745) for VM and OR = 1.06 (95% CI 0.44-2.51; p = 0.902) for MD, compared to BRV. Overall, 19 patients (43.2%) with BRV, 13 (38.2%) with VM, and 35 (81.0%) with MD used medication to prevent vertigo attacks at any point during their 3-year follow-up. Throughout the observation period patients with MD showed an average of 3.37 points (95% CI 0.68-6.07; p = 0.014) higher HADS scores relative to patients with BRV. Conclusion: The course of vertigo attacks was rather favorable in the three groups, as 67-70% of the patients were free of vertigo attacks after 3 years of follow-up. The course of disease in patients with BRV was not distinctive from patients with MD and VM. We assume that BRV is a mild or incomplete variant of VM and MD, rather than a separate disease entity with distinct pathognomonic features.

Long-term Prognosis of Vertigo Attacks and Health-related Quality of Life Limitations in Patients With Vestibular Paroxysmia.

OBJECTIVE: To explore the long-term course of outcomes in vestibular paroxysmia (VP). STUDY DESIGN: Cross-sectional observational study with a retrospective collection of baseline data. SETTING: Tertiary referral center. PATIENTS: Adult patients who visited the Apeldoorn Dizziness Center between 2010 and 2020 and were diagnosed with definite or probable VP according to the Bárány Society criteria were contacted by telephone to complete a study-specific questionnaire. Baseline data were retrospectively collected from patients electronic medical records to allow comparison between baseline and follow-up data. MAIN OUTCOME MEASURES: Vertigo attack frequency, use of carbamazepine and health-related quality of life (HRQoL) limitations were the primary outcomes. Secondary outcomes were the number of attack-free years and perceived effect of medication for VP. RESULTS: Seventy three patients were included, 61 (84%) of whom agreed to participate in the follow-up study. Mean age was 55.0 (SD 13.1) years, 49.2% were females. Mean follow-up was 3.4 years (range 0.4-11.3). At follow-up, 44 responders (72%) still experienced vertigo attacks. Average attack frequency in the past 6 months was 307 (SD 451) at baseline and 153 (SD 279) at follow-up (p = 0.050). At follow-up, 19.7% (n = 12) of the responders reported to use or have used carbamazepine, 58% of patients who (had) used this medication reported a positive perceived effect. Overall, 71% (n = 31) of the responders reported to have limitations in one or more HRQoL items due to their VP. CONCLUSION: Our study shows a rather unfavorable prognosis in patients with VP in terms of vertigo attacks and HRQoL limitations. After the initial diagnosis follow-up is warranted to monitor clinical outcomes in these patients.

From Discipline to Quality of Care: How Neurologists Can Learn from Decisions of Disciplinary Tribunals.

BACKGROUND: One of the primary aims of medical disciplinary law is to improve the quality of care. However, the decisions of disciplinary tribunals are not sufficiently analysed to identify the learning elements. AIM: This study aimed to investigate the frequency and nature of complaints for the specialty neurology which were upheld by the disciplinary tribunals and to learn from disciplinary law through an analysis of which factors contributed to complaints being upheld. DESIGN: This is a retrospective, observational study. METHODS: All upheld complaints in the field of neurology were collected for the period of January 1, 2010, to January 1, 2020. A qualitative analysis of the decisions was conducted using the usual characteristics set out by disciplinary tribunals in their annual reports. The relevant factors which potentially played a role in the complaint being upheld were identified for more detailed analysis. RESULTS: In the 10-year period, a complaint was submitted to the disciplinary tribunals against 299 neurologists. Forty-four complaints were upheld (15%). The most common sanction was a warning (70%). A large majority of cases were directly related to patient care, such as decisions about the patient's diagnosis and the treatment. Recordkeeping (50%), interpretation and discussion of imaging (30%), and involvement of several consultants of one or more specialties (34%) frequently played a role in the successful complaints. CONCLUSION: Medical disciplinary cases in the field of neurology are usually about diagnosis- and treatment-related aspects. Recordkeeping, interpretation of neuroimaging, and involvement of several consultants frequently play a role in a complaint being upheld. It is important that specialties evaluate disciplinary decisions on a structural and continuous basis.

Treatment Results of Geotropic and Apogeotropic Horizontal Canal Benign Paroxysmal Positional Vertigo in a Tertiary Dizziness Clinic.

Purpose: To determine the effectiveness of our treatment protocol for geotropic and apogeotropic horizontal canal benign paroxysmal positional vertigo (h-BPPV). Methods: We retrospectively evaluated patients with newly diagnosed geotropic and apogeotropic h-BPPV who visited our clinic between July 2017 and December 2019. Patients were treated according to our treatment protocol, which was implemented in 2017. Patients with geotropic h-BPPV were preferably treated with the Gufoni maneuver. In patients with apogeotropic h-BPPV we executed the modified Gufoni maneuver to achieve conversion to the geotropic type. We looked at the number of successful treatments and the number of recurrences within 1 year. Results: We included 102 patients with h-BPPV, 62 (61%) of whom were treated for geotropic h-BPPV. The ratio of apogeotropic to geotropic h-BPPV was 0.65. After the first visit, we observed resolution of horizontal canal BPPV in 71 and 63% of the geotropic and the apogeotropic group, respectively. After the second visit, this percentage increased to 92% for geotropic h-BPPV and 78% for apogeotropic h-BPPV. After 1 year of follow-up we determined a recurrence rate of 32 and 24% for the geotropic and apogeotropic group, respectively. Conclusion: With our treatment protocol we managed to achieve high rates of symptom resolution in the geotropic and apogeotropic type of h-BPPV with acceptable recurrence rates. We observed a relatively high ratio of apogeotropic h-BPPV to geotropic h-BPPV.

Dizziness and Driving From a Patient Perspective.

Background: People with dizziness may experience driving-related limitations. Few data are available about the impact of dizziness on driving. Aim: 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. Methods: 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. Results: 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. Conclusion: 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.

The relation between dizziness and suspected obstructive sleep apnoea.

PURPOSE: (1) To determine the prevalence of a high risk of obstructive sleep apnoea (OSA) in patients with dizziness. (2) To assess a relation between the risk of OSA and dizziness-related impairment. (3) To determine whether a high risk of OSA is associated with unexplained dizziness or with hyperventilation/anxiety disorders. METHODS: In this cross-sectional study, we included Dutch adult patients with dizziness. Patients suffering from dementia were excluded. We asked patients to complete the Dizziness Handicap Inventory (DHI) and STOP-Bang questionnaire (SBQ). Based on the SBQ, patients were subdivided into groups with a low, intermediate, and high risks of OSA. All patients were subjected to our standard examinations for the workup for dizziness. RESULTS: Among 704 included patients with a mean age of 59 years (± 17 years), 258 (37%) were male. A high risk of OSA was present in 144 (20%) of our patients of whom 120 (83%) were male. Male patients with a high risk of OSA reported an on average 9-point higher score on the DHI than male patients with a low risk of OSA (p = 0.018). We determined an independent relation between the risk of OSA and dizziness-related impairment. We observed no relation between a high risk of OSA and unexplained dizziness or hyperventilation/anxiety disorders. CONCLUSION: The prevalence of a high risk of OSA in male patients with dizziness is high and a higher risk of OSA is associated with more dizziness-related impairments. A high risk of OSA is not associated with unexplained dizziness or with hyperventilation/anxiety disorders.

Physical and Emotional Burden of the Epley Maneuver in the Elderly.

OBJECTIVE: To analyze and compare experiences of anxiety and discomfort caused by the Epley maneuver and the willingness for a potential retreatment between younger (≤70 yr) and older (>70 yr) patients. STUDY DESIGN: Prospective, observational cohort study. SETTING: Tertiary referral center. METHODS: Dutch adults, diagnosed with posterior canal benign paroxysmal positional vertigo, were included. Patients with dementia or subjected to an Epley maneuver ≤4 months before the hospital visit were excluded. Patients were asked about their experiences with the Epley maneuver directly after the maneuver, after 2 weeks and after 2 months. Differences in experiences between the age groups were tested with the Fisher's exact test and subgroup analyses were performed using multivariable logistic regression. RESULTS: Out of 179 included patients, 115 (64%) were aged ≤70 and 134 (75%) were female. In both groups, 25% reported anxiety directly after the Epley maneuver. Two weeks later, 19 and 27%, respectively (p = 0.26) reported anxiety. In the young group, 30% expressed discomfort directly after treatment compared with 45% in the elderly (OR 1.98, 95% CI 1.05-3.75, p = 0.04). Two weeks later, this was 36 and 38%, respectively (p = 0.87). This decreased to 24 and 33%, respectively (p = 0.37), after 2 months. There was no significant difference in willingness for potential retreatment between both groups after 2 weeks (93 and 95%, respectively, p = 0.75) nor after 2 months (97 and 92%, respectively, p = 0.13). CONCLUSION: The Epley maneuver results in little anxiety and discomfort both in young and in elderly patients. Most patients show willingness for potential retreatment in case symptoms recur.
