[PMID: 38793883 PMCID: PMC11125243 DOI: 10.3390/s24103028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 05/06/2024] [Accepted: 05/07/2024] [Indexed: 05/26/2024]
Abstract
Dizziness can be a debilitating condition with various causes, with at least one episode reported in 17% to 30% of the international adult population. Given the effectiveness of rehabilitation in treating dizziness and the recent advancements in telerehabilitation, this systematic review aims to investigate the effectiveness of telerehabilitation in the treatment of this disorder. The search, conducted across Medline, Cochrane Central Register of Controlled Trials, and PEDro databases, included randomized controlled trials assessing the efficacy of telerehabilitation interventions, delivered synchronously, asynchronously, or via tele-support/monitoring. Primary outcomes focused on dizziness frequency/severity and disability, with secondary outcomes assessing anxiety and depression measures. Seven articles met the eligibility criteria, whereas five articles contributed to the meta-analysis. Significant findings were observed regarding the frequency and severity of dizziness (mean difference of 3.01, p < 0.001), disability (mean difference of -4.25, p < 0.001), and anxiety (standardized mean difference of -0.16, p = 0.02), favoring telerehabilitation. Telerehabilitation shows promise as a treatment for dizziness, aligning with the positive outcomes seen in traditional rehabilitation studies. However, the effectiveness of different telerehabilitation approaches requires further investigation, given the moderate methodological quality and the varied nature of existing methods and programs.

Etiologic distribution of dizziness/vertigo in a neurological outpatient clinic according to the criteria of the international classification of vestibular disorders: a single-center study. J Neurol 2024; 271:2446-2457. [PMID: 38231268 PMCID: PMC11055744 DOI: 10.1007/s00415-023-12166-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 12/19/2023] [Accepted: 12/20/2023] [Indexed: 01/18/2024]
Abstract
OBJECTIVE The study aimed to determine the etiological characteristics of patients with dizziness/vertigo attending a neurological clinic according to the criteria of the International Classification of Vestibular Disorders (ICVD), hoping to provide a valuable reference for clinicians to diagnose and treat dizziness/vertigo. METHOD A total of 638 consecutive patients with a chief complaint of dizziness/vertigo who attended the vertigo clinic of our neurology department from January 2019 to January 2020 were included. Clinical data of patients, including baseline data, medical history, neurological, neuro-otological, and auxiliary examination results were collected. The etiologic distribution of dizziness/vertigo was determined by analyzing the diagnoses of patients. RESULTS Of the 638 patients with dizziness/vertigo, 38.8% were males, 61.2% were females, with a male: female ratio of 1:1.58 and a mean age of 52.9 ± 16.9 years. Benign paroxysmal positional vertigo (BPPV) was the most common cause of dizziness/vertigo in both female (38.9%) and male patients (25.5%). Subgroup analysis based on sex showed that vestibular migraine (VM) and probable autoimmune inner ear disease (p-AIED) were more prevalent in female patients (10.7% and 3.8%, respectively), while vascular vertigo/dizziness was more common in male patients (10.1%). Subgroup analysis based on age showed that the most common diseases were VM in patients aged 0-30 years (27.4%), BPPV in patients aged 31-60 years (27.1%) and 61-100 years (46.0%). Episodic vestibular syndrome (EVS) was the most commonly observed, accounting for up to 60.6% (389/638) of all patients, and the most common diagnoses were BPPV (55.3%, 215/389), VM (15.2%, 59/389), primary unilateral peripheral vestibular dysfunction (p-UPVD) of unknown etiology (11.8%, 46/389), p-AIED (4.4%, 17/389), and vascular vertigo/dizziness (2.8%, 11/389) in these patients. Chronic vestibular syndrome (CVS) was found in 14.0% (90/638) of the patients, and the most common diagnoses were persistent postural-perceptual dizziness (PPPD, 35.6%, 32/90), psychogenic dizziness (18.9%, 17/90), p-UPVD of unknown etiology (15.6%, 14/90), vascular vertigo/dizziness (15.6%, 14/90), and bilateral vestibulopathy (7.8%, 7/90). Acute vestibular syndrome (AVS) was observed in 8.4% (54/638) of the patients, and the most common diagnoses were p-UPVD of unknown etiology (31.5%, 17/54), vestibular neuritis (24.1%, 13/54), probable labyrinthine apoplexy (16.7%, 9/54), stroke (13.0%, 7/54), and psychogenic dizziness (11.1%, 6/54). 16.4% (105/638) of the patients were found to have other disorders, including 15.2% (16/105) of patients with internal diseases, and 84.8% (89/105) of patients with unknown causes. In terms of localization diagnosis, 56.1%, 17.0%, 10.0%, and 16.4% of the patients were diagnosed with peripheral vestibular disorder, central vestibular disorder, psychiatric and functional vestibular disorders, and other disorders, respectively. CONCLUSION (1) Dizziness/vertigo was more common in females, which was frequently caused by damage to the vestibular system. Non-vestibular or unknown etiologies were also seen in some patients; (2) VM was more prevalent in women than in men, vascular vertigo/dizziness was more commonly observed in men; (3) EVS was more common in patients with dizziness/vertigo. The most common causes of dizziness/vertigo were peripheral vestibular disorders in patients with AVS and EVS, PPPD and psychogenic dizziness in patients with CVS. The most common causes were BPPV and p-UPVD of unknown etiology in patients with a peripheral vestibular disorder, VM and vascular vertigo/dizziness in patients with central vestibular disorder, PPPD and psychogenic dizziness in patients with psychiatric and functional vestibular disorders.

[PMID: 38395721 DOI: 10.1016/j.vaccine.2024.02.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 02/12/2024] [Accepted: 02/17/2024] [Indexed: 02/25/2024]
Abstract
INTRODUCTION Evidence regarding audiovestibular adverse events post COVID-19 vaccination to date has been inconclusive regarding a potential association. This study aimed to determine if there was an increase in audiovestibular events following COVID-19 vaccination in South-eastern Australia during January 2021-March 2023. METHODS A multi-data source approach was applied. First, a retrospective observational analysis of spontaneous reports of audiovestibular events to a statewide vaccine safety surveillance service, SAEFVIC. Second, a self-controlled case series analysis using general practice data collected via the POpulation Level Analysis and Reporting (POLAR) tool. RESULTS AND CONCLUSIONS This study is the first to demonstrate an increase in general practice presentations of vertigo following mRNA vaccines (RI = 1.40, P <.001), and tinnitus following both the Vaxzevria® adenovirus vector and mRNA vaccines (RI = 2.25, P <.001 and 1.53, P <.001 respectively). There was no increase in hearing loss following any COVID-19 vaccinations. Our study, however, was unable to account for the potential of concurrent COVID-19 infections, which literature has indicated to be associated with audiovestibular events. Healthcare providers and vaccinees should be alert to potential audiovestibular complaints after COVID-19 vaccination. Our analysis highlights the importance of using large real-world datasets to gather reliable evidence for public health decision making.

Cost-Effectiveness of CT, CTA, MRI, and Specialized MRI for Evaluation of Patients Presenting to the Emergency Department With Dizziness. AJR Am J Roentgenol 2024; 222:e2330060.

Abstract
BACKGROUND. Underlying stroke is often misdiagnosed in patients presenting with dizziness. Although such patients are usually ineligible for acute stroke treatment, accurate diagnosis may still improve outcomes through selection of patients for secondary prevention measures. OBJECTIVE. The purpose of our study was to investigate the cost-effectiveness of differing neuroimaging approaches in the evaluation of patients presenting to the emergency department (ED) with dizziness who are not candidates for acute intervention. METHODS. A Markov decision-analytic model was constructed from a health care system perspective for the evaluation of a patient presenting to the ED with dizziness. Four diagnostic strategies were compared: noncontrast head CT, head and neck CTA, conventional brain MRI, and specialized brain MRI (including multiplanar high-resolution DWI). Differing long-term costs and outcomes related to stroke detection and secondary prevention measures were compared. Cost-effectiveness was calculated in terms of lifetime expenditures in 2022 U.S. dollars for each quality-adjusted life year (QALY); deterministic and probabilistic sensitivity analyses were performed. RESULTS. Specialized MRI resulted in the highest QALYs and was the most cost-effective strategy with US$13,477 greater cost and 0.48 greater QALYs compared with noncontrast head CT. Conventional MRI had the next-highest health benefit, although was dominated by extension with incremental cost of US$6757 and 0.25 QALY; CTA was also dominated by extension, with incremental cost of US$3952 for 0.13 QALY. Non-contrast CT alone had the lowest utility among the four imaging choices. In the deterministic sensitivity analyses, specialized MRI remained the most cost-effective strategy. Conventional MRI was more cost-effective than CTA across a wide range of model parameters, with incremental cost-effectiveness remaining less than US$30,000/QALY. Probabilistic sensitivity analysis yielded similar results as found in the base-case analysis, with specialized MRI being more cost-effective than conventional MRI, which in turn was more cost-effective than CTA. CONCLUSION. The use of MRI in patients presenting to the ED with dizziness improves stroke detection and selection for subsequent preventive measures. MRI-based evaluation leads to lower long-term costs and higher cumulative QALYs. CLINICAL IMPACT. MRI, incorporating specialized protocols when available, is the preferred approach for evaluation of patients presenting to the ED with dizziness, to establish a stroke diagnosis and to select patients for secondary prevention measures.

Abstract
OBJECTIVE Determine levels of catastrophizing in patients with vestibular disorders and prospectively evaluate their relationship with patient-reported outcome measures. STUDY DESIGN Prospective cohort study. SETTING Tertiary care neurotology vestibular disorders clinic. PATIENTS Adult patients with various vestibular disorders. INTERVENTIONS Patients were given the Dizziness Handicap Inventory (DHI) and the Dizziness Catastrophizing Scale (DCS) at a baseline visit and follow-up visit after treatment. MAIN OUTCOME MEASURES Correlation studies were used to determine the relationships between DHI and DCS. Multivariable linear regression was performed to determine the relationship between DCS and DHI change with treatment, accounting for demographic variables. RESULTS Forty-six subjects completed both the DHI and the DCS before and after treatment. Patients with higher baseline DCS scores had higher baseline DHI scores ( p < 0.001). There was a significant improvement in both DHI score ( p < 0.001) and DCS ( p < 0.001) at follow-up. Patients who had reduction in DCS scores during were more likely to show reduction in DHI scores ( p < 0.001). A subset of patients had a mindfulness-based stress reduction program included in their treatment. These patients had a greater reduction in both DCS and DHI scores at follow-up compared with those who received other treatments. CONCLUSIONS Catastrophizing is associated with higher pretreatment DHI scores and worse treatment outcomes. Addressing dizziness catastrophizing may help improve vestibular outcomes.

Abstract
Introduction Acute vertigo is a frequent chief complaint in the emergency departments, and its efficient management requires thorough training. The HINTS protocol is a valid method to screen patients in the emergency room, but its application in routine is hindered by the lack of training. This study aimed to evaluate the training of emergency physicians for the HINTS method based on a mannequin-based virtual reality simulator (MBVRS). Methods We conducted a monocenter, prospective, longitudinal, and randomized cohort study in an Emergency Department at a regional university hospital. We included 34 emergency physicians randomized into two equal groups matched by age and professional experience. The control group attended a theoretical lesson with video demonstrations and the test group received a simulation-based training in addition to the lecture. Results We showed that the test group had a higher diagnosis performance for the HINTS method compared to the control group as evaluated by the simulator at 1 month (89% sensitivity versus 45, and 100% specificity versus 86% respectively, p < 001, Fisher's exact test). Evaluation at 6 months showed a similar advantage to the test group. Discussion The MBVRS is a useful pedagogic tool for the HINTS protocol in the emergency department. The advantage of a unique training session can be measured up to 6 months after the lesson.

Altered functional activity of the precuneus and superior temporal gyrus in patients with residual dizziness caused by benign paroxysmal positional vertigo. Front Neurosci 2023; 17:1221579. [PMID: 37901419 PMCID: PMC10600499 DOI: 10.3389/fnins.2023.1221579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Accepted: 09/29/2023] [Indexed: 10/31/2023] Open
Abstract
Objective Benign paroxysmal positional vertigo (BPPV) is a common clinical vertigo disease, and the most effective treatment for this disease is canal repositioning procedures (CRP). Most patients return to normal after a single treatment. However, some patients still experience residual dizziness (RD) after treatment, and this disease's pathogenesis is currently unclear. The purpose of this study is to explore whether there are abnormal brain functional activities in patients with RD by using resting-state functional magnetic resonance imaging (rs-fMRI) and to provide imaging evidence for the study of the pathogenesis of RD. Materials and methods The BPPV patients in the Second Affiliated Hospital of Xuzhou Medical University had been included from December 2021 to November 2022. All patients had been received the collection of demographic and clinical characteristics (age, gender, involved semicircular canal, affected side, CRP times, BPPV course, duration of RD symptoms, and whether they had hypertension, diabetes, coronary heart disease.), scale assessment, including Dizziness Handicap Inventory (DHI), Hamilton Anxiety Inventory (HAMA), Hamilton Depression Inventory (HAMD), rs-fMRI data collection, CRP treatment, and then a one-month follow-up. According to the follow-up results, 18 patients with RD were included. At the same time, we selected 19 healthy individuals from our hospital's physical examination center who matched their age, gender as health controls (HC). First, the amplitude of low-frequency fluctuations (ALFF) analysis method was used to compare the local functional activities of the two groups of subjects. Then, the brain regions with different ALFF results were extracted as seed points. Functional connectivity (FC) analysis method based on seed points was used to explore the whole brain FC of patients with RD. Finally, a correlation analysis between clinical features and rs-fMRI data was performed. Results Compared to the HC, patients with RD showed lower ALFF value in the right precuneus and higher ALFF value in the right superior temporal gyrus (STG). When using the right STG as a seed point, it was found that the FC between the right STG, the right supramarginal gyrus (SMG), and the left precuneus was decreased in RD patients. However, no significant abnormalities in the FC were observed when using the right precuneus as a seed point. Conclusion In patients with RD, the local functional activity of the right precuneus is weakened, and the local functional activity of the right STG is enhanced. Furthermore, the FC between the right STG, the right SMG, and the left precuneus is weakened. These changes may explain the symptoms of dizziness, floating sensation, walking instability, neck tightness, and other symptoms in patients with RD to a certain extent.

Front Neurol 2023; 14:1256826. [PMID: 37808489 PMCID: PMC10557255 DOI: 10.3389/fneur.2023.1256826] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 09/05/2023] [Indexed: 10/10/2023] Open
Abstract
Background Video head impulse tests (vHITs), assessing the vestibulo-ocular reflex (VOR), may be helpful in the differential diagnosis of acute dizziness. We aimed to investigate vHITs in patients with acute posterior circulation stroke (PCS) to examine whether these findings could exhibit significant abnormalities based on lesion locations, and to evaluate diagnostic value of vHIT in differentiating dizziness between PCS and vestibular neuritis (VN). Methods We prospectively recruited consecutive 80 patients with acute PCS and analyzed vHIT findings according to the presence of dorsal brainstem stroke (DBS). We also compared vHIT findings between PCS patients with dizziness and a previously studied VN group (n = 29). Receiver operating characteristic (ROC) analysis was performed to assess the performance of VOR gain and its asymmetry in distinguishing dizziness between PCS and VN. Results Patients with PCS underwent vHIT within a median of 2 days from stroke onset. Mean horizontal VOR gain was 0.97, and there was no significant difference between PCS patients with DBS (n = 15) and without (n = 65). None exhibited pathologic overt corrective saccades. When comparing the PCS group with dizziness (n = 40) to the VN group (n = 29), patients with VN demonstrated significantly lower mean VOR gains in the ipsilesional horizontal canals (1.00 vs. 0.57, p < 0.001). VOR gain and their asymmetry effectively differentiated dizziness in the PCS from VN groups, with an area under the ROC curve of 0.86 (95% CI 0.74-0.98) and 0.91 (95% CI 0.83-0.99, p < 0.001), respectively. Conclusion Significantly abnormal vHIT results were rare in patients with acute PCS, even in the presence of DBS. Moreover, vHIT effectively differentiated dizziness between PCS and VN, highlighting its potential for aiding differential diagnosis of acute dizziness.

Tsunoda R, Fushiki H, Tanaka R, Endo M. A new portable Fresnel magnifying loupe for nystagmus observation: a clinical education and clinical practice setting study. BMC MEDICAL EDUCATION 2023; 23:472. [PMID: 37355593 DOI: 10.1186/s12909-023-04466-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 06/20/2023] [Indexed: 06/26/2023]
Abstract
BACKGROUND Dizziness is a common complaint of patients treated by primary care physicians. It is predominantly caused by peripheral vestibular disorders; however, central nervous system disorders should be excluded. Examination of the eye movements and nystagmus can help differentiate the disorders of the central nervous system from the peripheral vestibular disorders; however, it is often not performed appropriately. In medical education practice, nystagmus observation may facilitate an understanding of vestibular function and nystagmus characteristics. Thus, we proposed a medical education practice to master nystagmus observation using a recently developed portable Fresnel magnifying loupe that could be shielded by one eye. METHODS Thirty-three students from the Department of Physical Therapy and the Department of Speech, Language, and Hearing Therapy of the Mejiro University participated in this study. Postrotatory nystagmus was measured and compared using the new loupe and control methods, namely the naked eye and Frenzel goggles; we rated the ease of visibility using a five-point scale. RESULTS The number of detected cases of nystagmus was significantly higher with the new loupe than with the naked eye (p = 0.001). In addition, there were no significant differences in the nystagmus counts between the observations using the new loupe and Frenzel goggles (p = 0.087). No significant difference was observed in the visibility of eye movements between the loupe and naked eye (p = 1.00). The Frenzel goggles provided better visibility compared to that by the loupe (p = 0.034); however, none of the participants reported poor visibility using any of these methods. CONCLUSIONS Our newly developed Fresnel loupe allows for the observation of nystagmus counts a level of reduction in fixation suppression similar to that of Frenzel goggles in an educational practice setting. Furthermore, it enables the detection of significantly more nystagmus counts compared to that by the naked eye. It offers several advantages over Frenzel goggles, including its lightweight, thin, durable, and portable design. Additionally, the loupe does not rely on a power source and can be used under normal room lighting conditions. TRIAL REGISTRATION This study was approved by the Medical Research Ethics Committee of Mejiro University (approval number: 21medicine-021).

Abstract
Vertigo, a symptom of illusory movement, is caused by asymmetry of the vestibular system. The vestibular system consists of the vestibular labyrinth, cranial nerve VIII, brainstem vestibular nuclei, cerebellum, ocular motor nuclei, spinal cord, and less well-defined cerebral projections. In this day and age of artificial intelligence, machine learning, advanced imaging, and cutting-edge research in the field of neurology, the exact cortical control of vestibular function is still uncharted. A 45-year-old woman with a past medical history of labyrinthitis about 4.5 years ago (resolved) presented to hospital due to severe dizziness, emesis, and mild vertical diplopia for the past few days. Her symptom of dizziness i.e. room spinning was continuous without any postural component. MRI of the brain revealed a small stroke in the left hippocampal area, more specifically alveus of hippocampus. The patient was started on dual antiplatelet therapy and atorvastatin for secondary stroke prevention. Follow-up visit as an outpatient at one-month post hospital discharge was unremarkable without any recurrence of vertigo symptoms. We believe this may indicate that the limbic lobe has a much larger role in vestibular functioning than previously thought, and may control more vestibular operations than any other central nervous system area.

Eur J Med Res 2023; 28:170. [PMID: 37179360 PMCID: PMC10181921 DOI: 10.1186/s40001-023-01123-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 04/18/2023] [Indexed: 05/15/2023] Open
Abstract
BACKGROUND AND OBJECTIVES The treatment of elderly patients is an increasing challenge and the long-term sequelae often affect activities of daily living and quality of life in those patients. Handgrip strength (HGS) appears as a promising value to predict the outcome after trauma in elderly patients and to assess the overall muscle strength. Besides the possible role of psychological and hormonal factors, vitamin D may have a positive influence. Furthermore, some data suggest that Vitamin D is beneficial regarding muscle strength and possibly prevents further falls and injuries in orthogeriatric patients. The purpose of this study was to identify if Vitamin D is an influencing factor for HGSin elderly trauma patients. MATERIALS AND METHODS 94 elderly patients in a Level I Trauma Center aged 60 years or older were prospectively enrolled and HGS as well as serum 25-OH Vitamin D concentration (VDC) were measured. In addition, the standardized questionnaires Barthel Index (BI), Parker Mobility Score (PMS), Short Physical Performance Battery (SPPB), Strength, Assistance with walking, Rise from a chair, Climb stairs and Falls (SARC-F) and European Quality of Life 5 Dimensions 5 Levels Questionnaire (EQ-5D-5L), were used to record mental health status and demographic data. RESULTS HGS is mainly related to age and sex in elderly trauma patients. HGS was higher in men (meanmale = 27.31 kg (± 8.11), meanfemale = 15.62 kg (± 5.63), p < 0.001 and decreased with age (βage = - 0.58, p < 0.001). A significant negative correlation between HGS and VDC exists in the overall sample (βVDC = - 0.27, pVDC < 0.008), which still remains after adjusting for age (pVDC < 0.004), but is not significant after adjustment for both main confounders, age and sex (pVDC < 0.08). Furthermore, the HGS was lower in pateints who reported frequent falls, stumbling, dizziness or a late onset of menopause, and decreased if patients felt anxious or depressed during measurements (βanxiety+depression = - 0.26, panxiety+depression < 0.01). CONCLUSIONS These results do not support the hypothesis that Vitamin D has a positive influence on muscle strength measured by HGS. Nevertheless, this study could confirm the usefulness of HGS as a tool to detect the risk for frequent falls or stumbling. Furthermore, HGS seems to be associated with dizziness and age at onset of menopause. A significant decrease of HGS could also be shown in patients with anxiety and depression. This underlines the importance of interdisciplinary treatment of elderly trauma patients and needs to be taken into account for further studies, as especially the psychological motivation seems to have a significant influence and is sometimes not considered enough in elderly musculo-skeletal patients.

Abstract
COVID-19 has infected millions of people worldwide causing millions of deaths. COVID-19 has many serious effects on organs of the body especially the respiratory system causing pneumonia and acute respiratory distress syndrome (ARDS). The disease also has severe complications on other different organs; kidneys and liver which may end in multi-organ failure. Most common symptoms that have been detected in large section of patients were fever, cough and loss of taste or smell and less commonly sore throat, headache and muscle pain. The incidence of vertigo or dizziness is a rare symptom of COVID-19. In this case report, we introduce a 59-year-old male patient suffering from acute vertigo attack after COVID-19 infection. The patient had negative medical history of vertigo and any ear diseases. The patient received REGEN-COV (casirivimab and imdevimab) for COVID-19 and meclizine for vertigo. Vertigo attacks lasted for the two weeks follow up after disappearance of COVID-19 symptoms despite receiving vertigo medication. In conclusion, vertigo may be the sole neurological manifestation of COVID-19. More observational studies should address this symptom and researchers should also focus on identifying the origin of developing vertigo and the direct or indirect mechanisms that SARS-CoV-2 triggers to develop dizziness in general. This research should deliver a clear message, especially to ER physicians to consider proper referral of these patients without underestimating the risk of developing more serious COVID-19 symptoms as ARDS and multi-organ failure if no proper testing and follow-up are provided.

Abstract
INTRODUCTION Vertigo/dizziness is defined as disturbed postural awareness and could range from a feeling of sensation of spinning of self or surrounding. Dizziness or disturbed postural awareness is a common presentation in varying age groups. Vertigo has varied clinical presentations. Classically, there are four vertigo syndromes: vertigo, imbalance/disequilibrium, presyncope/lightheadedness, and psychogenic dizziness. The present study was conducted to examine the various etiologies involved in these syndromes and to help unmask the overlaps between them. This study also aimed to further classify the etiologies underlying these vertigo syndromes and overlaps into peripheral or vestibular, central, and non-vestibular. This would help develop a comprehensive management protocol for vertigo of any origin. METHODS A prospective observational cross-sectional study was undertaken in a rural hospital in Central India. We studied patients with giddiness and categorized them into vertigo syndromes according to the site of origin of vertigo. We also compared overlaps in the presentation of vertigo. RESULTS Out of the 80 patients that were studied, vertigo with disequilibrium was observed in 72.50% of the patients. Non-vestibular vertigo of cervicogenic origin was the common cause of vertigo seen in 36.25% of the patients occurring alone or in association with vestibular vertigo. Among patients with overlaps, vestibular vertigo with non-vestibular vertigo was the most common etiology observed in 89.65% of the patients with overlaps. CONCLUSION The syndrome of "vertigo with disequilibrium" was the commonest presentation in the patients studied, followed by "vertigo syndrome" as an isolated symptom, not associated with "disequilibrium." Ours is probably the first study to report this observation of overlaps of two syndromes, with diagnostic implications.

Abstract
OBJECTIVE To understand the videonystagmography (VNG) findings in various balance disorders in 67 patients who presented to the outpatient department of an otorhinolaryngology clinic. MATERIALS AND METHODS This cross-sectional study was conducted in the outpatient department of the otorhinolaryngology clinic of a tertiary care center. A total of 67 patients between the age group of 18 and 70 years with balance disorders were included in the study. VNG findings in different balance disorders were observed and analyzed. RESULTS A total of 67 patients were enrolled in the study. Findings like caloric inversion and optokinetic nystagmus do not always indicate a central balance disorder due to technical errors and other limitations during the test. However, abnormal saccades seem to be a more relevant finding in central disorders. Rare variants of benign paroxysmal positional vertigo (BPPV) like multiple canal BPPV were also diagnosed using VNG. CONCLUSION VNG has come out as a very useful test in our study aiding in 75% of diagnoses. The overall benefits of VNG in balance disorders are immense and necessitate their inclusion in every vertigo clinic.

Abstract
Dizziness is one of the most common symptoms encountered by physicians daily. It is divided into four categories: vertigo, disequilibrium, presyncope, and psychogenic dizziness. It is essential to distinguish these four symptoms because the causes, prognosis, and treatment differ. Vertigo constitutes a disease of the central or peripheral nervous system. Central origin vertigo may be a life-threatening situation and must be detected as soon as possible because it includes diseases such as stroke, hemorrhage, tumors, and multiple sclerosis. Peripheral origin vertigo includes benign diseases, which may be fully treatable such as vestibular migraine, benign paroxysmal positional vertigo, vestibular neuritis, Ménière’s disease, and cervical vertigo. The HINTS (head impulse, nystagmus, test of skew) examination is essential to distinguish central from peripheral causes. A detailed history including the duration of vertigo (episodic or continuous), its trigger, and a clinical examination step by step following the appropriate protocol could help to make a definite and accurate diagnosis and treatment. Due to a lack of expertise in dizziness and inappropriate treatment, many patients are admitted to dizziness clinics with long-standing dizziness. A holistic treatment combining medications, vestibular rehabilitation, physiotherapy, and psychotherapy should be initiated to improve the quality of life of these patients. So, this review aims to recommend a clinical protocol for approaching a dizzy patient with vertigo and to present in detail the epidemiology, pathophysiology, symptoms, diagnosis, and contemporary treatments of all causes of vertigo.

Abstract
BACKGROUND Bow hunter’s syndrome (BHS) is a rare but surgically treatable cause of vertebrobasilar insufficiency due to dynamic rotational occlusion of the vertebral artery. Typically, patients present with posterior circulation transient ischaemic symptoms such as presyncope, syncope, vertigo, diplopia, and horizontal nystagmus, but irreversible deficits, including medullary and cerebellar infarctions, have also been described.
CASE SUMMARY A 70-year-old patient presented an acute onset of vertigo and gait instability triggered by right head rotation. His medical history included previous episodes of unilateral left neck and occipital pain followed by light-headedness, sweating, and blurred vision when turning his head, and these episodes were associated with severe degenerative changes in the atlanto-dens and left atlanto-axial facet joints and right rotation of the C2 cervical vertebrae. Brain magnetic resonance imaging revealed the presence of acute bilateral cerebellar ischaemic lesions, while static vascular imaging did not reveal any vertebral artery abnormalities. Dynamic ultrasonography and angiography were performed and confirmed the presence of a dynamic occlusion of the vertebral artery V3-V4 segment when the head was rotated to the right secondary to left C1-C2 bone spur compression. Surgical decompression led to complete resolution of paroxysmal symptoms without neurological sequelae.
CONCLUSION BHS should be considered in cases of repeated posterior circulation transient ischaemic attack or ischaemic stroke, particularly when associated with high cervical spine abnormalities.

Abstract
The videonystagmography oculomotor test battery is considered useful method for diagnosing vertigo. However, its role in diagnosing central vestibular disorder has not been clarified due to variations in interpretation. Patients (n = 103) with vertigo or dizziness symptoms undergoing the oculomotor tests and brain MRI within 1 month were analyzed. Two otology specialists retrospectively interpreted the oculomotor tests, and three neurology and neuroradiology specialists determined whether central lesions were present on brain MRI. Multivariable logistic regression analysis was performed to determine the factors contributing to discordant interpretation between oculomotor tests and brain MRI. Oculomotor tests predicting central lesions were assessed using principal component analysis. The intra- and inter-rater reliability in oculomotor test interpretation was moderate to good. Age > 60 years and multiple comorbidities were significant predictors of a discordant interpretation between MRI and oculomotor tests. Positive neurological symptoms and a higher oculomotor index (according to saccade (vertical axis), smooth pursuit (horizontal axis), and gaze-evoked nystagmus (horizontal/vertical axes) tests) significantly predicted central vestibular disorder in vertigo patients. Caution is required when interpreting the results of the oculomotor test battery for diagnosis of central lesions in older patients, as well as in those with multiple comorbidities.

Abstract
OBJECTIVE To translate and evaluate psychometric properties of Thai version of the Dizziness Handicap Inventory (DHI-TH). STUDY DESIGN A cross-sectional study. SETTING Ambulatory. PATIENTS Fifty patients with dizziness at a vestibular clinic. MAIN OUTCOME MEASURES Translation and cross-cultural adaptation of the original English version of the DHI was performed according to published guidelines. Psychometric evaluation included internal consistency, content validity, test-retest reliability, convergent validity, discriminant ability, and responsiveness. Responsiveness was examined in 28 patients with vestibular dysfunction who received vestibular rehabilitation for 6 to 8 weeks. RESULTS There were no floor and ceiling effects. The Cronbach's alpha was good for the total score (0.87) and subscale scores (0.70 physical, 0.73 emotional, and 0.71 functional). Excellent test-retest reliability was demonstrated for the total and subscales (ICC ranged from 0.91 to 0.97, p < 0.001). The SEM was 3.50 and the MDC was 9.68. The total and subscales of DHI-TH were moderately correlated with the SF-36-TH scores (r ranged from -0.40 to -0.63). An optimal cut-off point for detection of dizziness was 21 points (98% sensitivity, 94% specificity). Responsiveness of the DHI-TH was excellent. The ES and SRM were large (1.25 and 1.59, respectively). The DHI-TH discriminated well between patients with self-perceived improved dizziness versus unchanged dizziness (AUC = 0.87). The MCID was 17 points (82.0% sensitivity, 82.0% specificity). CONCLUSION The DHI-TH demonstrated good psychometric properties for patients with dizziness. The DHI-TH is a valid and reliable instrument recommended as a measure of disability and quality of life in Thai patients with dizziness.

Immersive Virtual Reality and Vestibular Rehabilitation in Multiple Sclerosis: Case Report. JMIR Serious Games 2021; 10:e31020. [PMID: 34766551 PMCID: PMC8892276 DOI: 10.2196/31020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 09/07/2021] [Accepted: 10/12/2021] [Indexed: 02/06/2023] Open
Abstract
Background Dizziness and imbalance are common and disabling symptoms in patients with multiple sclerosis (MS) and are caused by a central, peripheral, or mixed vestibulopathy. Central vestibular disorder is the most frequently reported vestibular problem in the MS population due to demyelination. Vestibular rehabilitation ameliorates these symptoms and their repercussions and improves quality of life. Immersive virtual reality (VRi) is an emerging tool in this field; however, no previous research has been performed studying its effects in MS. Objective The aim of this study was to apply a VRi vestibular training protocol to a patient with MS and assess the effects induced by the experimental intervention. Methods This case study included a 54-year-old woman with relapsing-remitting MS. We developed a standardized VRi exercise protocol for vestibular rehabilitation based on the gold-standard Cawthorne-Cooksey vestibular training protocol. The 20-session intervention was made up of 10 initial sessions and 10 advanced sessions. Each 50-minute session was performed two to three times per week for 7 weeks. Four evaluations were carried out over the study period: at baseline (T0), between initial and advances phases (T1), postintervention (T2), and 1 month after the experimental procedure (T3). The research outcomes were dizziness, balance, gait, impact of fatigue, quality of life, repercussions in muscular tone, and usability of the head-mounted display device. Results After implementing the VRi vestibular protocol, improvements were seen in the following patient parameters: Dizziness Handicap Inventory score (62 points at T0; 4 points at T2); Berg Balance Scale score (47 points at T0; 54 points at T2); instrumented Timed Up and Go time (8.35 seconds at T0; 5.57 seconds at T2); muscular tone of the erector spinae, rectus femoris, and soleus; Modified Fatigue Impact Scale score (61 points at T0; 37 points at T2); and Multiple Sclerosis Quality of Life-54 values (67.16% in the physical health area at T2; 33.56% in the mental health area at T2). The patient rated the usability of the system as 90%, based on the System Usability Scale, and gave the system a grade of A. Conclusions Although further research is needed, this study provided initial evidence that the first VRi vestibular protocol for the MS population can improve dizziness, balance, gait, impact of fatigue, quality of life, and muscular tone through an exergame intervention. This study may help establish a standardized VRi protocol for vestibular rehabilitation.

Front Sports Act Living 2021; 3:703982. [PMID: 34447930 PMCID: PMC8384176 DOI: 10.3389/fspor.2021.703982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 07/05/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Vestibular deficit is common following concussion and may affect gait. The purpose of this study was to investigate differences in head and pelvic center of mass (COM) movement during gait in military tactical athletes with and without concussion-related central vestibular impairment. Material and Methods: 24 patients with post-concussion vestibular impairment (20 males, 4 females; age: 31.7 ± 7.9 years; BMI: 27.3 ± 3.3) and 24 matched controls (20 males, 4 females; age: 31.8 ± 6.4 years; BMI: 27.2 ± 2.6) were included in the analyses. Three-dimensional head and pelvic displacement and velocities were collected at a 1.0 m/s standardized treadmill walking speed and assessed using Statistical Parametric Mapping t-tests. Maximum differences (dmax) between groups were reported for all significant kinematic findings. Results: The Vestibular group demonstrated significantly diminished anteroposterior head excursions (dmax = 2.3 cm, p = 0.02) and slower anteroposterior (dmax = 0.37 m/s, p = 0.01), mediolateral (dmax = 0.47 m/s, p = 0.02) and vertical (dmax = 0.26 m/s, p < 0.001) velocities during terminal stance into pre-swing phases compared to the Control group. Vertical pelvic excursion was significantly increased in midstance (dmax = 2.4 cm, p = 0.03) and mediolaterally during pre- to initial-swing phases (dmax = 7.5 cm, p < 0.001) in the Vestibular group. In addition, pelvic velocities of the Vestibular group were higher mediolaterally during midstance (dmax = 0.19 m/s, p = 0.02) and vertically during post-initial contact (dmax = 0.14 m/s, p < 0.001) and pre-swing (dmax = 0.16 m/s, p < 0.001) compared to the Control group. Significance: The Vestibular group demonstrated a more constrained head movement strategy during gait compared with Controls, a finding that is likely attributed to a neurological impairment of visual-vestibular-somatosensory integration.

Abstract
In addition to the known pathophysiological sequelae of the SARS-COV-2 virus and its related respiratory symptoms, several studies have recently reported cardiovascular, gastrointestinal, and neurological symptoms of new-onset after a history of infection. Vertigo is a symptom indicating dysfunction of the vestibular system and this report of a 60-year-old female patient points out the possible association between new-onset vertigo and SARS-COV-2 infection. A 60-year-old diabetic and hypertensive female patient with a 9-days history of COVID-19 symptoms presented to the emergency department with acute vertigo attack without nausea or vomiting. A full physical examination showed no other auditory or neurological symptoms and she never experienced vertigo before. Laboratory findings confirmed a current COVID-19 infection. The patient was managed with antihypertensive, anti-vertigo medications, and COVID-19 protocol for mild cases. After discharge, the patient was advised to continue the anti-vertigo drugs and COVID-19 medications. SARS-COV-2 may lead to vestibular neuritis causing vertigo and other related symptoms, but more well-designed observational studies with a large sample size are needed to establish a definite association between COVID-19 and vertigo.

Abstract
BACKGROUND Dizziness affects 20-30%of the general population. A subgroup of dizzy patients with chronic migraine suffers vertigo implying that the migraine has a vestibular component. Vestibular migraine remains a diagnosis of exclusion based on history. OBJECTIVE A link between headaches and dizziness suggests that these individuals would demonstrate dizziness and instability in complex, dynamic visual environments as a result of an inability to correctly process conflicting visual and vestibular signals. METHODS A convenience sample of 74 patients (22 men and 52 women; average age 56.2 years) who presented with complaints of dizziness participated. Effects of Visual-Vestibular Mismatch (VVM) were measured using a modified VVM questionnaire. Visual dependence was measured as the error to subjective visual vertical using a computerized Rod and Frame test. RESULTS Forty-two participants (56.8%) tested positive for VVM. Of these, 68.9%were patients with concomitant complaints of headaches. Visual dependence was present in 41.5%of all patients but showed no significant correlation with headache. 22.2%of patients had visual dependence and complained of headaches. CONCLUSIONS These results demonstrate that sensory reweighting occurs in patients experiencing dizziness and headache, supports the role of vestibular involvement in this disorder, and provides future direction for novel interventions.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:4787.

Abstract
Vertigo is not itself a disease, but rather a symptom of various syndromes and disorders that jeopardize balance function, which is essential for daily activities. It is an abnormal sensation of motion that usually occurs in the absence of motion, or when a motion is sensed inaccurately. Due to the complexity of the etiopathogenesis of vertigo, many pharmacological treatments have been tested for efficacy on vertigo. Among these drugs, cinnarizine, usually given together with dimenhydrinate, appears to be the first-line pharmacotherapy for the management of vertigo and inner ear disorders. Based on these considerations, the present non-interventional study aimed to investigate the clinical efficacy and tolerability of a fixed combination of cinnarizine (20 mg) and dimenhydrinate (40 mg) in patients suffering from vertigo-related symptoms. To this end, we enrolled 120 adults-70 males, and 50 females-with an average age of 64 years. Before beginning pharmacological treatment, all patients were screened for the intensity of vertigo, dizziness, and concomitant symptoms through the Visual Scale of Dizziness Disorders and Dizziness Handicap Inventory scales. At the end of the anamnestic evaluation, patients received the fixed-dose combination of cinnarizine (20 mg) plus dimenhydrinate (40 mg) 3 times daily, for 60 days. The results of this study provide further insight regarding the efficacy of the fixed combination when used to reduce symptoms of vestibular vertigo of central and/or peripheral origin, after both the 15- and 60-day therapies. Independent of the type of vertigo, the fixed combination was able to reduce dizziness- and vertigo-associated symptoms in more than 75% of all patients treated, starting from 15 days of therapy, and improving 60 days after starting the therapy. Interestingly, we also found differences between male and female patients in the framework of the pharmacological effects of therapy. This study provides further details concerning the therapeutic efficacy of the fixed combination of cinnarizine and dimenhydrinate, and also focuses attention on the possibility that these drugs could act in a gender-specific manner, paving the way for further research.

Abstract
OBJECTIVES This study examines the usefulness of computed tomography (CT) scans in evaluating patients with dizziness in the emergency department (ED). METHODS Medical records of patients presented with complaints of dizziness or vertigo to the ED of a tertiary university hospital and underwent head CT scans from July 2015 to June 2018 were reviewed. The patients' demographic information, presenting symptoms, and final head CT scan and Magnetic resonance imaging (MRI) results were collected. Stepwise logistic regressions were used to analyze data. RESULTS A total of 326 dizzy patients were included in this study. The majority of the patients (83.1%) were older than 44 years. Acute vertigo pattern of dizziness was detected among 50.6% of the patients and was more common among females than males (p < 0.001). Of these 326 patients who underwent head CT scans, 49 (15%) had abnormal findings with acute ischemic stroke was the most common one. A total of 191 patients underwent follow-up studies. MRI accounted for 70% of the follow-up studies. Of the 134 patients who received MRI of the brain, 36 (27%) had abnormal findings. A significant correlation of RBCs level, presence of other symptoms, and frequency of episodes with the presence of vertigo (p < 0.001) was found. CONCLUSION The study's findings indicate low effectiveness of head CT scan compared to MRI for dizziness management. Future studies are suggested to provide more insights into the cost-effectiveness and utility of head CT scans and MRI in providing valuable findings.

Abstract
OBJECTIVE Irritability is an emotional stress symptom that causes or exacerbates dizziness. Antidepressants may be helpful for some conditions that are accompanied by irritability; however, they do not completely inhibit irritability. Yokukansan (YKS), a traditional Japanese herbal medicine, has been used for neurosis, insomnia, and children's irritability and night crying. The study investigated the efficacy of YKS in nystagmus in patients with chronic dizziness and irritability. METHODS Twenty-two cases with chronic dizziness and irritability were reviewed retrospectively. The patients were divided into two groups: control patients (0-7 days of treatment) and YKS-treated patients (YKS cases; >7 days of treatment). Dizziness before and during (after, in the controls) YKS treatment was evaluated by scoring the nystagmus intensity on a 5-point scale. The average scores were calculated within a maximum of 6 months before and during or after treatment. The normalized scores were also calculated. The optimal treatment regimen was calculated via receiver operating characteristic (ROC) curve analysis. RESULTS There were six control cases (1 male, 5 females; mean age: 59.5 years). There were 16 YKS cases (3 males, 13 females; mean age: 61.8 years). While the group mean nystagmus intensity scores significantly decreased from 1.18 to 0.73 in the YKS cases, it did not change in the control cases. The group mean of the normalized nystagmus intensity scores during treatment was 0.73 in the YKS cases. The results of the ROC curve analysis indicated the optimal cut-off period of the YKS treatment was 10 days. CONCLUSION The oral administration of YKS for more than 10 days was optimal. The treatments with YKS could be a good option for the treatments of vertigo.

Abstract
OBJECTIVE To assess the usefulness of head and neck computed tomography angiogram for the investigation of isolated dizziness in the emergency department in detecting significant acute findings leading to a change in management in comparison to non-contrast computed tomography scan of the head. METHODS Patients presenting with isolated dizziness in the emergency department investigated with non-contrast computed tomography and computed tomography angiogram over the span of 36 months were included. Findings on non-contrast computed tomography were classified as related to the emergency department presentation versus unrelated/no significant abnormality. Similarly, computed tomography angiogram scans were classified as positive or negative posterior circulation findings. RESULTS One hundred and fifty-three patients were imaged as a result of emergency department presentation with isolated dizziness. Fourteen cases were diagnosed clinically as of central aetiology. Non-contrast computed tomography was positive in three patients, all with central causes with sensitivity 21.4%, specificity 100%, positive predictive value 100%, negative predictive value 92.6% and accuracy 92.8%. Computed tomography angiogram was positive for angiographic posterior circulation abnormalities in five cases, and only two of them had a central cause of dizziness, with sensitivity 14.3%, specificity 97.7%, positive predictive value 40%, negative predictive value 91.46% and accuracy 92.1%. CONCLUSION Both non-contrast computed tomography and computed tomography angiogram of the head and neck have low diagnostic yield for the detection of central causes of dizziness, However, non-contrast computed tomography has higher sensitivity and positive predictive value than computed tomography angiogram, implying a lack of diagnostic advantage from the routine use of computed tomography angiogram in the emergency department for the investigation of isolated dizziness. Further studies are required to determine the role of computed tomography angiogram in the work-up of isolated dizziness in the emergency department.

Abstract
OBJECTIVE To evaluate whether Chronic Isolated Light-headedness (CIL) commonly manifested in elderly patients is related with cerebral oxygen insufficiency. METHODS In this case-control study, 462 patients (aged 40-83 years) with CIL and 238 clinical data matched controls were enrolled consecutively from January 2011 to September 2014. The plasma levels of "phospholipids with solubility similar to that of lysophosphatidic acid" (PSS-LPA), a surrogate marker for cerebral oxygen insufficiency, were assayed for all subjects to compare the occurrence and severity of CIL with the values of PSS-LPA. RESULTS Patients with CIL had significantly higher plasma levels of PSS-LPA than controls, regardless of having or having not psychogenic abnormalities, χ2 = 448, odds ratio (95% CI) = 140 (72-260), P < 0.001; the mean plasma levels, 0.573 vs. 0.290 mmol/L respectively (P < 0.001). Receiver operator characteristic (ROC) analyses showed plasma PSS-LPA was both sensitive and specific for CIL. The area under ROC curve (AUC) was as high as 0.953 (0.938-0.968). The changes in severity of CIL between two separate assays of one month apart were correlated closely with the changes in plasma levels of PSS-LPA for the same patients, correlation coefficient (Spearman) = 0.90, p < 0.001. CONCLUSIONS CIL is a manifestation of abnormal plasma levels of phospholipids which suggests cerebral oxygen insufficiency. This new finding shows that cerebral oxygen insufficiency is not rare especially in elderly persons.

Abstract
OBJECTIVE To assess the long-term stability of caloric testing in patients. METHODS In this retrospective study, Cronbach's alpha was used to determine whether caloric testing results are stable over time (up to 7 years) in patients who have not undergone interventions. After excluding invalid records, two hundred patients who underwent repeated caloric testing in the same lab over varying periods of time were included. RESULTS Cronbach's alpha scores were 0.512 for unilateral weakness and 0.051 for the sum of caloric tests indicating that the stability of caloric tests is poor over long terms. CONCLUSION The stability of caloric testing with repeated testing over long terms is not reliable.

Abstract
Background: The treatment of benign paroxysmal positional vertigo (BPPV) has not been well studied. Many clinicians are indifferent about canalith reposition maneuvers and frequently prefer medical treatments. Objectives: We aimed to detect efficacy of Epley maneuver in relieving symptoms of benign paroxysmal positional vertigo patients diagnosed in emergency department and if medical treatments are useful in patients whose symptoms were not relieved. Methods: The study was conducted as a prospective cohort study in the emergency department of a tertiary hospital. Patients who were over 18 years of age and presented to emergency department with complaints of vertigo symptoms and nausea and had a positive Dix–Hallpike test were included in the study. Patients’ demographic data, possible etiological factors, affected ear, and benign paroxysmal positional vertigo diagnosis in the history were recorded on the study data form. The European Evaluation of Vertigo scale and the Visual Analogue Scale (VAS) score of nausea and vertigo symptoms were graded and recorded for each patient before and after treatment. Results: Ninety patients were included in the study in total. Epley maneuver was carried out to all patients. Vertigo symptoms VAS (VASd) score (p < 0.001), nausea and vomiting VAS (VASnv) score (p < 0.001), and European Evaluation of Vertigo scale score (p < 0.001) of all patients showed a statistically significant decrease after Epley maneuver. A combination of dimenhydrinate and metoclopramide helped to reduce VASd (p = 0.048), VASnv (p = 0.031), and European Evaluation of Vertigo scale scores (p = 0.001) at a statistically significant level more than dimenhydrinate treatment alone. Conclusions: Epley maneuver may be applied to every patient with benign paroxysmal positional vertigo. Dimenhydrinate and/or metoclopramide helps to control patients’ symptoms whose symptoms remain despite Epley maneuver.

Abstract
Objective: Videonystagmography (VNG) is a commonly ordered test to evaluate patients with vestibular complaints. To date, there are no evidence-based guidelines for evaluating patients presenting with vestibular symptoms. This study evaluates the cost effectiveness of VNG and the impact of VNG findings on patient management. Methods: Patient charts were reviewed from 3 institutions to collect the pre- and post-VNG ICD-9/10 diagnosis and treatment plan. VNG findings were recorded to calculate the incidence of abnormal findings and the incidence of change in diagnosis and/or treatment plan. The cost effectiveness of VNG was estimated based on these calculations. Results: A total of 120 patient charts were reviewed. 69/120 (57.5%; 95% CI: 48.2%-66.5%) patients had abnormal findings on their VNG. A change in diagnosis was noted in 24/120 (20.0%; 95% CI: 13.3%-28.3%) patients. A change in treatment plan was noted in 62/120 (51.7%; 95% CI: 42.4%-60.9%) patients, and 11/120 (9.2%; 95% CI: 4.7%-15.8%) had a change in diagnosis that led to change in treatment plan. Using the average Medicare reimbursement for VNG, the cost effectiveness analysis showed a cost of $869.57 per VNG with abnormal findings and a cost of $5454.55 per VNG that lead to a change in diagnosis and treatment plan. Conclusions: VNG findings may not result in changes in clinical diagnosis. However, VNG is impactful at influencing treatment plan changes. VNG results are beneficial for counseling patients, guiding treatment plans, and managing patient expectations. When there is a clear indication, VNG testing can be cost effective in managing patients presenting with vestibular symptoms.

Abstract
Objective Peripheral vertigo is one of the most common causes of the emergency department (ED) visits. It can impair balance and might predispose patients to injuries after discharge. The purpose of this study was to determine whether peripheral vertigo is associated with an increased risk of trauma. Methods This matched-cohort study used the nationally representative dataset of de-identified claim information of 1 million randomly sampled individuals from a real Korean population, from 2002 to 2013. The exposure cohort included patients who visited EDs for new-onset peripheral vertigo without prior or concurrent injury. Each patient was randomly matched to five unexposed individuals (also without previous injury) by incidence density sampling. The primary outcome was a new injury within 1 year. The secondary outcomes were various injury subtypes. The time-dependent effect of the exposure was modeled using the extended Cox model. Age, sex, comorbidities, and household income level were included as covariates. Results A total of 776 and 3,880 individuals were included as the exposure and comparison cohorts, respectively. The risks of trunk injury and upper extremity injury were significantly higher in the exposure cohort. Extended Cox models with multivariable adjustment showed significantly increased risk for up to 1 year, with the first 1-month; 1 month to 3 months; and 3 months to 1 year hazard ratios of 5.23 (95% confidence interval [CI], 2.83–9.64); 1.50 (95% CI, 1.02–2.20); and 1.37 (95% CI, 1.11–1.68), respectively. Conclusion Patients visiting EDs for acute peripheral vertigo are at a higher risk of a new injury for up to a year.

Abstract
Dizziness is one of the most common symptoms in medicine. For differentiation of peripheral or central origin of the vertigo, history and clinical examination with detection of a nystagmus is essential. The aim of this study was to detect horizontal vestibular nystagmus utilizing a webcam. In the feasibility study, caloric induced vestibular nystagmus was recorded with conventional video-nystagmography and webcam. Analysis of recorded data was performed with a developed software which used computer vision techniques. A designed algorithm detected nystagmus existence and their direction. The software was evaluated by an expert-rated video-nystagmography. Webcam-based vestibular nystagmus detection is possible. Currently, a clinical application is not approved. Further software improvements are necessary to increase its accuracy.

Abstract
The Benign Paroxysmal Positional Vertigo (BPPV) represents the first cause of peripheral vertigo in populations and it is determined by a displacement of otoconial fragments within the semicircular canals. Following the patient’s head movements, these fragments, moving by inertia, incorrectly stimulate the canals generating vertigo. The BPPV is diagnosable by observing the nystagmus that is generated in the patient following the Dix-Hallpike maneuver used for BPPV diagnosis of vertical semi-circular canal, and, following the supine head yaw test used for lateral semi-circular canal. Correctly identifying the origin of this specific peripheral vertigo, would mean to obtain a faster diagnosis and an immediate resolution of the problem for the patient. In this context, this study aims to identify precise training activities, aimed at the application of specific diagnostic maneuverers for algorithm decisions in support of medical personnel. The evaluations reported in this study refer to the data collected in the Emergency Department of the Cardarelli Hospital of Naples. The results obtained, over a six-month observation period, highlighted the advantages of the proposed procedures in terms of costs, time and number of BPPV diagnoses.

Abstract
Dizziness is one of the most frequent complaints encountered in the medical practice affecting 15%-20% of adults yearly, and can be challenging to assess. Most patients use dizziness as a non-specific term, and thus suffer prejudice from the physicians' end and can be disregarded frequently. Dizziness can be a symptom of various diseases, some with sinister pathologies. We present a case of garden-variety vertigo that unfurled to be not-so-simple, emphasizing the importance of a thorough history and physical examination again even in the era of technology. A 32-year-old male patient with no past medical history presented with dizziness, later clarified as gradually progressive vertigo for two years, with unstable gait, dysarthria, and occasional diplopia. Physical examination found sustained nystagmus that changed direction with horizontal gaze, vertical nystagmus with upward gaze, dysarthria, and a wide-based ataxic gait. CT head without contrast revealed indeterminate hypodense areas in the left midbrain, pons, and cerebellar hemisphere. MRI brain identified a 2.8 x 3.4 x 4.2 cm Spetzler-Martin grade IV brainstem arteriovenous malformation (AVM) involving the left midbrain, pons, and cerebellum. Feeders were mostly from the posterior circulation, with three intranidal aneurysms, all draining into the deep venous system. The AVM was deemed inoperable, and the patient was treated with onyx embolization for two/three feeding vessel aneurysms. After treatment, the symptoms persisted, and the patient was diagnosed with major depressive disorder (MDD) six months after diagnosis, and was admitted a year later with suicidal ideation and substance use disorder. Brain AVMs are rare clinical entities that present in 0.1% of the population, mostly presenting as intracranial bleeds. When they do rarely present with isolated focal neurologic deficits, it has been attributed to a vascular steal phenomenon, hemorrhage, or a mass effect. The isolated findings of vertigo and dysarthria are highly non-specific; with such presentation, clinicians should consider etiologies under the realm of vertigo of central origin. An untreatable AVM reduces patients' quality of life and has been linked to depression and anxiety, and thus patients may benefit from psychosocial therapy. Although preventing intracranial hemorrhage (ICH) is the primary concern with brain AVMs, the rest of the patient's profile should not be forgotten.

Abstract
BACKGROUND AND PURPOSE The Life Space Assessment (LSA) is a self-report measure that allows clinicians to determine how often someone moves around in his or her environment with or without assistance. Presently, there are no reliable and valid measures that capture all 3 aspects of mobility (ie, mobility frequency, distance, and assistance needed) for individuals with vestibular disorders. The purpose of this study was to describe life space and to determine the reliability and concurrent validity of the LSA as a tool to measure mobility and function in individuals with balance and vestibular disorders. METHODS One hundred twenty-eight participants (mean age of 55 ± 16.7 years) experiencing dizziness or imbalance who were seeking the care of an otoneurologist were recruited. Participants completed the LSA, Dizziness Handicap Inventory (DHI), and the 12-Item Short Form Health Survey (SF-12). RESULTS The mean LSA score of the sample was 75/120 ± 30. The LSA demonstrated excellent test-retest reliability (intraclass correlation coefficient = 0.91). The LSA was negatively correlated with the DHI total score (ρ = -0.326, P < 0.01), DHI physical subscore (ρ = -0.229, P = 0.02), DHI functional subscore (ρ = -0.406, P < 0.01), and DHI emotional subscore (ρ = -0.282, P < 0.01). The LSA was positively correlated with both the physical (ρ = 0.422, P < 0.01) and mental (ρ = 0.362, P < 0.01) composite scores of the SF-12. DISCUSSION AND CONCLUSIONS Similar to the findings in community-dwelling older adults, the LSA demonstrated excellent test-retest and internal consistency in individuals with vestibular disorders. The LSA is a valid and reliable tool for measuring mobility and function in individuals with vestibular disorders.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A317).

Abstract
Background and objectives: To date, no study has investigated the ability of optic nerve sheath diameter calculated from non-contrast brain computed tomography to predict acute cerebellar infarction in patients with acute vertigo. The aim of our study was to evaluate the predictive utility of optic nerve sheath diameter for diagnosing acute cerebellar infarction in patients with acute vertigo without computed tomography abnormalities. Methods: We retrospectively enrolled patients with acute vertigo without computed tomography abnormalities who underwent magnetic resonance imaging including diffusion-weighted imaging at our emergency department between January 2016 and December 2017. Two emergency physicians independently measured optic nerve sheath diameter at 3 mm (ONSD3) and 10 mm (ONSD10) behind the globe in each patient. Final magnetic resonance imaging reports with clinical progress notes were used as the reference standard. A multivariate logistic regression analysis, receiver operating characteristic curves, and intra-class correlation coefficients were calculated to estimate predictive value. Results: A total of 34 patients (16.1%) were diagnosed with acute infarction and 177 patients (83.9%) were diagnosed with peripheral vertigo. Mean ONSD3 ( p < 0.001) and ONSD10 ( p < 0.001) were independent predictive factors for distinguishing acute infarction and peripheral vertigo. ONSD3 (cut-off = 4.22 mm) had 100% (95% confidence interval = 89.7–100.0) sensitivity and 97.7% (95% confidence interval = 95.1–99.6) specificity with area under the receiver operating characteristic curve of 0.988 (95% confidence interval = 0.978–1.0), while ONSD10 (cut-off = 3.63 mm) had 100% (95% confidence interval = 89.7–100.0) sensitivity and 87.6% (95% confidence interval = 81.8–92.0) specificity with area under the receiver operating characteristic curve of 0.976 (95% confidence interval = 0.959–0.997). There were good inter- and intra-observer agreements for both sides of ONSD3 and ONSD10 (intra-class correlation coefficient range = 0.652–0.773). Conclusion: Optic nerve sheath diameter, in particular OSND3, is a feasible predictive marker for acute infarction in patients with acute vertigo without computed tomography abnormalities. This information can assist decision-making in ordering brain magnetic resonance imaging for the assessment of acute vertigo.

Abstract
Background: Balance problems can severely limit the quality of life for people with Multiple Sclerosis (pwMS) already in the early stages of the disease. PwMS are usually assessed with the Expanded Disability Status Scale (EDSS), which includes a Romberg test for assessing balance. As the EDSS assessments are subjective to the examining neurologist, the postural stability of pwMS could be objectively quantified by implementing static posturography to detect balance problems and address preventive medical care. Methods: In this cross-sectional study, we added static posturography to the neurological EDSS examination in pwMS and healthy subjects to determine how this technique could supply additional information during the evaluation of the cerebellar functional system of the neurostatus EDSS as clinical outcome already in early disease stages. Static posturography was performed with subjects standing on a force platform while outcome variables such as delineated area, average speed and average sway were obtained. Unpaired t-test as well as (Welch's) analysis of variance (ANOVA) with pairwise post-hoc comparisons according to Games-Howell were used. Spearman rank correlations were implemented to study associations of balance outcomes with EDSS-associated outcomes. Results: A total of 99 pwMS (mean age: 35.01 years; EDSS median: 2.0, 68.69% females) and 30 healthy subjects (mean age: 34.03 years; 70% females) were enrolled. PwMS had worse performances in the three evaluated balance parameters than the healthy group (all p < 0.001). Even patients without postural instability as documented in the Romberg test score of the EDSS assessment showed significantly worse outcome regarding the delineated area [+1.97 cm2, 95%-CI (0.61-3.34); p = 0.002] vs. healthy controls. Similar results were observed for the comparison between pwMS with normal cerebellar function EDSS-systems and healthy subjects. There were significant correlations with the EDSS, cerebellar function score and Romberg test for the delineated area and average speed (r's ranging from 0.330 to 0.537, p < 0.001). Conclusions: Static posturography can complement neurological assessment of EDSS as an objective and quantitative test, especially for MS patients in early stages of the disease.

Abstract
PURPOSE This study aims to evaluate the efficacy of head shake movement on three head movement planes (yaw, pitch and, roll) in patients with dizziness despite normal vestibular test results. MATERIALS AND METHODS Twenty individuals aged between 20 and 51 years with complaints of dizziness were included in the study, and their results were compared with the results from twenty age- and gender-matched controls. Participants were assessed using the Sensory Organization Test, Head Shake-Sensory Organization Test which is based on the modification of the Sensory Organization Test on the yaw, pitch, and roll planes, videonystagmography, caloric test, and Dizziness Handicap Inventory. RESULTS Significant differences were found in the yaw (p = 0.007), pitch (p < 0.001), and roll (p = 0.002) planes between the study and control groups of the Head Shake-Sensory Organization Test-5 scores. There were no statistically significant differences between the two groups of the Head Shake-Sensory Organization Test-2 scores in the yaw (p = 0.448), pitch (p = 0.213), and roll (p = 0.531) planes. When the sensitivity and specificity of Head Shake-Sensory Organization Test-5 conditions were examined, the highest specificity was observed in the pitch plane (100%), followed by the yaw (95%) and roll plane (95%). CONCLUSION Dynamic head movements are an important parameter for the evaluation of balance performance. The head shake modification could be used effectively in three-movement planes in individuals with dizziness.

Abstract
Background: Vertigo is 1 of the most prominent and frequent neurological symptom. It is estimated that about 30% of all people need medical care once in their life due to this index symptom. The neurological expertise required is usually scarce in underprivileged areas. One has to look for spontaneous nystagmus, and perform Dix–Hallpike maneuver and Head Impulse test specifically to differentiate central from peripheral vertigo. The nystagmus, that is spontaneous, involuntary to-and-fro movement of the eyeball which aids in the diagnosis, can be better elicited by Frenzel glasses, Munich glasses. These devices consist of the combination of magnifying glasses and a lighting system to detect eye movements better than routine examination. Objective: To test usefulness of modified Google cardboard as Frenzel glasses in poor resource setting. Study design: A modified Google cardboard was used in 52 consecutive cases of vertigo and compared with examination with naked eye. The device consists of 2 magnifying lenses, 1 for each eye with power of +24 dioptres. Observation: The tool was found to be better for identifying spontaneous nystagmus, in Dix–Hallpike maneuver and during head impulse test as compared with the naked eye owing to the property of magnification and inhibition of fixation. Being a cheaper alternative and handy, it could be carried by every doctor in any setting.

Abstract
AIM The aim of this study was to analyze the prevalence of dizziness- and vertigo-related diagnoses in ear, nose, and throat (ENT) practices in Germany and the associated demographic characteristics based on data from a representative nationwide practice database. METHOD The study sample included patients from 138 ENT practices in Germany who received dizziness- and vertigorelated diagnoses (ICD-10 code) between January 2012 and December 2015. Collected parameters included age, sex, insurance status, prescribed medication (anatomical therapeutic chemical [ATC] class), and referrals to other specialists and hospitals. RESULTS A total of 107,458 patients were available for analysis. Most common diagnoses were "dizziness and giddiness" (67.7%), "benign paroxysmal vertigo" (10.2%) and "disorder of vestibular function, unspecified" (7.2%). Referrals and admissions were made in 12.8%, mostly to radiologists (7.7%), followed by neurologists (3.7%), and hospitals (1.4%). Most referrals were made for unspecific diagnoses and for "vestibular neuronitis." The rate of medical prescriptions was 37.3%, with the most common prescription being for antivertigo preparations. CONCLUSIONS Dizziness- and vertigo-related disorders are frequently diagnosed in ENT practices in Germany. The majority of these diagnoses are unspecific and lead to an increased rate of referrals and hospital admissions. The medical prescription rate, especially of antivertigo preparations, was high, even among patients with benign paroxysmal positioning vertigo. This study reflects a mostly pragmatic approach to a complex diagnostic and therapeutic challenge in daily ENT practice as well as the limited ability of the ICD-10 system to classify the underlying etiology.

Abstract
Importance Catastrophizing is a maladaptive thought process that involves irrational fear and worry about anticipated or actual symptoms. Although clinically relevant, the role of catastrophizing in patients with chronic dizziness or imbalance has not yet been explored to our knowledge. Objectives To validate a measure of dizziness catastrophizing and to assess its association with dizziness-related disability compared with other negative affect constructs (eg, anxiety and depression). Design, Setting, and Participants For this retrospective medical record review, the Dizziness Catastrophizing Scale (DCS), a dizziness-specific catastrophizing assessment tool, was adapted from the previously validated Pain Catastrophizing Scale. Psychometric evaluation of the DCS was performed. In addition, the associations of dizziness catastrophizing and positive and negative affectivity with dizziness-related disability were assessed using structural equation modeling and regression analyses. Data were collected using a retrospective medical record review from April 27, 2010, to June 25, 2014. The dates of analysis were June 3 to August 15, 2017. The setting was the Multidisciplinary Neurotology Clinic at the Toronto General Hospital (Toronto, Ontario, Canada). Participants were 457 adult outpatients with dizziness or imbalance who were referred to the clinic. Main Outcomes and Measures Psychometric properties of the DCS and its association with dizziness-related disability, as measured with the Dizziness Handicap Inventory. Results Among 457 patients (mean [SD] age, 53.4 [15.4] years; 154 [33.7%] male), the DCS demonstrated good convergent (r = 0.78, P < .001) and discriminant validity (r = -0.40, P < .001) with the negative and positive affectivity, respectively; internal consistency (α = .95); and test-retest reliability (intraclass correlation coefficient, 0.92; P < .001 at the 95% CI). An exploratory dimension reduction analysis revealed a single latent component of the DCS. The results of the structural equation modeling and regression analyses revealed that dizziness catastrophizing, although associated with negative affectivity (eg, symptoms of anxiety and depression), was independently associated with dizziness-related disability (standardized β = 0.378; P < .001). Furthermore, a strong association was found between catastrophizing and dizziness-related disability across different dizziness-related diagnoses (r ≥ 0.6; P < .001). Conclusions and Relevance In this study, the DCS was a valid and reliable measure for evaluating catastrophic thinking in patients with dizziness, which was independently associated with dizziness-related disability. Future studies should investigate the influence of alleviating symptoms of catastrophizing on functional outcomes in patients with dizziness or imbalance, the results of which will help guide novel approaches to the clinical care of patients with chronic dizziness.

Abstract
The review considers the results of domestic and foreign studies of modern neurophysiological diagnosis of vestibular disorders in migraine and epilepsy. Currently, there is a large number of physiological and clinical methods to evaluate the functions of the peripheral and central parts of the vestibular sensory system. However, among the tests, the samples for the assessment of the physiological state of horizontal semicircular canals and associated stem canals predominate. In recent years, neurophysiological techniques that reflect the work of the structures of the nervous system, previously inaccessible to direct study, are being actively introduced. Modern effective neurophysiological methods of rehabilitation of patients with migraine-associated and other various vestibular disorders have been developed. Further study of neurophysiological approaches to the diagnosis of vestibular disorders in migraine and epilepsy will significantly expands the current understanding of neurophysiological mechanisms of brain functions.
