RESUMO
Vertigo and dizziness are among the most common chief complaints in the neurology and emergency departments. Benign, self-limiting peripheral causes such as benign positional paroxysmal vertigo or vestibular neuropathy, Ménière's disease are the majority, but dangerous underlying conditions such as cerebrovascular or cardiovascular diseases are still overlooked. In this paper, the anatomy of the vestibular network from peripheral to central and the classification based on "triggers and timing" rather than the analysis of patient's word (rotational versus dizzy) are presented. Based on these, I classify various causes of vertigo and dizziness into three groups, i.e. highly dangerous, less dangerous but cautionary, and benign self-limiting ones, and explain them focusing on isolated vertigo or isolated vestibular syndrome.

BACKGROUND: Correctly diagnosing dizziness in children is essential for appropriate management; nevertheless, healthcare professionals face challenges due to children's limited ability to describe their symptoms and their cooperation during physical examination. The objective of this study is to describe the first 100 patients seen at a newly established pediatric vertigo center. METHODS: This is a retrospective review of a consecutive series of 100 patients seen at our pediatric vertigo clinic in a tertiary referral center from August 2019 until June 2022. Comprehensive clinical data were collected. The diagnoses were established by 2 pediatric otolaryngologists based on validated diagnostic criteria. Trends in diagnosis, investigation, and treatment of these patients were analyzed. RESULTS: A total of 100 children were included in the study. Vestibular migraine was the most common diagnosis (20%) followed by benign paroxysmal vertigo of childhood (14%). Eleven patients had combined pathologies. Fifteen out of 70 children (21%) had abnormal audiograms, 30 out of 48 children (62.5%) had abnormal vestibular testing, and 6 out of 31 (19%) patients had abnormal imaging. Fifty-one children received medical treatment, 23 received vestibular physiotherapy, and 9 patients had particle repositioning maneuvers; moreover, 17 of these patients received multimodal treatment. CONCLUSIONS: Our analysis suggests that imaging and audiology testing have relatively low yield in the assessment of pediatric vertigo. On the other hand, vestibular testing detected a high proportion of abnormalities, such as saccadic pursuit, vertical nystagmus, central positional nystagmus, and abnormal directional preponderance, particularly associated with vestibular migraine. Given the complexity of diagnosing vertigo in children, it is critical to establish multidisciplinary specialized centers capable of providing accurate diagnosis and treatment for these children.

BACKGROUND: Fibromyalgia syndrome (FMS) is a chronic pain condition that may be associated with dysfunction in the central nervous system. OBJECTIVE: The aim of this study was to assess the vestibulo-spinal reflex (VSR) and vestibulo-ocular reflex (VOR) in FMS using the cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP) tests, respectively, and to evaluate their relation to disease severity. METHODS: This study included 30 female FMS patients and 30 well-matched healthy controls. They underwent full history taking and assessment of the severity of dizziness/vertigo using the Dizziness Handicap Inventory; assessment of the severity of FMS symptoms using the Revised Fibromyalgia Impact Questionnaire; bedside examination of the dizzy patient; videonystagmography, cVEMP, and oVEMP tests; basic audiologic evaluation; and uncomfortable loudness level (UCL) testing. RESULTS: Dizziness was reported in 46.6% and vertigo in 11.1% of patients. Abnormalities in cVEMP (50%) and oVEMP (63.3%) were mostly unilateral, irrespective of FMS severity. Disease duration affected only the oVEMP amplitude. Fibromyalgia syndrome patients had a statistically significant lower UCL and narrower dynamic range compared to controls. CONCLUSION: The VSR and VOR are commonly affected in FMS patients, and findings suggest central sensitization involving the brain stem. We recommend routine cVEMP and oVEMP testing to assess brainstem function in FMS patients.

The issuing of International Classification of Vestibular Disordersï¼ICVDï¼ by Bî¤rî¤ny societyï¼2015ï¼ greatly facilitates the progress of vestibular medicine. The syndromic classification of vestibular disorders by ICVD enable the physician to narrow the spectrum of differential diagnosis for the vestibular disorder in clinical practice. However, the division of vestibular pathway, especially the central vestibular system, has not be classified yet in the ICVDï¼2015ï¼. Central vertigo, being a group of heterogeneous disorders, may present diverse clinical spectrums. The misdiagnosis of central vestibular as well as peripheral vestibular disorders have been reported in the clinic practice. Therefore, the author by review study proposes a structural classification of vestibular disorders combined the Vestibular System Functional Anatomy Division with Syndromesï¼VeSFADSï¼. The VeSFADS classification of vestibular disorders could help the physician in clinical practice to narrow the spectrum of vestibular disorders, in addition to the syndromic classification, by the clinical feature of vestibular disorders from different division of vestibular system. And the VeSFADS classification of vestibular disorders may facilitate to clarify the clinical features of vestibular disorders at different Division of vestibular pathway.

Vertigo, an unexpected feeling of self-motion, is no longer characterized simply by symptom quality but by using triggers and timing. Evaluating vertigo by triggers and timing not only distinguishes serious central causes from benign peripheral causes, but also narrows the differential diagnosis by further classifying vertigo as spontaneous episodic vestibular syndrome, triggered episodic vestibular syndrome, or acute vestibular syndrome. A targeted physical examination can then be used to further delineate the cause within each of these three vestibular categories. Neuroimaging and vestibular testing are not routinely recommended. In the management of vertigo, vestibular hypofunction can be treated with vestibular rehabilitation, which can be self-administered or directed by a physical therapist. Pharmacotherapy sometimes is indicated for vertigo based on triggers, timing, and the specific condition, but it is not always beneficial and is used more often for symptom reduction than as a cure. Transtympanic corticosteroid or gentamicin injections are recommended for patients who do not benefit from nonablative therapy. Surgical ablative therapy is reserved for patients who have not benefited from less definitive therapy and have nonusable hearing.

BACKGROUND: To improve diagnostic precision in pediatric vertigo, particularly in Vestibular Migraine of Childhood (VMC), probable VMC (pVMC), Recurrent Vertigo of Childhood (RVC), and unspecified categories, by delineating clinical characteristics and prevalence to refine diagnostics and treatments. METHODS: Retrospective analysis of 102 pediatric patients (five to 18 years; 46 females, 56 males) at the Dizziness Center of the Otolaryngology Department in a tertiary-level hospital from January 2019 to December 2023. Patients were classified into VMC, pVMC, RVC, and indeterminate groups. Evaluations included audiometry and vestibular tests (video head impulse test [vHIT] or caloric testing), conducted in the audiology unit and vestibular testing laboratory. Data were analyzed using IBM SPSS 20.0. RESULTS: Diagnoses were 8.8% VMC, 31.4% pVMC, 51.0% RVC, and 8.8% indeterminate. Nausea and vomiting were common in VMC and pVMC; cochlear symptoms like tinnitus and hearing loss predominated in VMC. Although vestibular testing showed no significant group differences, VMC had more vHIT abnormalities and RVC had more caloric test anomalies. CONCLUSIONS: This study highlights the need for comprehensive diagnostics in pediatric vestibular disorders, revealing unique and overlapping traits across VMC, pVMC, and RVC. Insights call for further research to refine diagnostic criteria and improve treatment methods.

Objective: To investigate the disease composition, clinical features, diagnosis, and treatment characteristics of vertigo in children. Methods: A total of 120 children with vertigo diagnosed and treated in the Department of Otorhinolaryngology, Children's Hospital, Capital Institute of Pediatrics in Beijing from February 2018 to February 2022 were retrospectively analyzed to explore the clinical characteristics of common peripheral vertigo in children and to summarize the experience of diagnosis and treatment. Results: The etiological composition of 120 cases of vertigo in children are as follows: 63 (52.5%) cases of vestibular migraine of childhood (VMC), 19 (15.8%) of recurrent vertigo of childhood (RVC), 11 (9.2%) of probable vestibular migraine of childhood (PVMC), 10 (8.3%) of secretory otitis media (SOM), 6 (5.0%) of persistent postural-perceptual dizziness (PPPD), 4 (3.3%) of benign paroxysmal positional vertigo (BPPV), 2 (1.7%) of vestibular neuritis (VN), 2 (1.7%) of Meniere's disease (MD), 2 (1.7%) of inner ear malformation (IEM), and 1 (0.8%) of vestibular paroxysmal syndrome (VP).The major cause of vertigo in children of different ages was different. SOM was the most important cause in preschool children, followed by RVC and VMC; VMC was the most important cause in school-age children, followed by RVC; and MD and BPPV were exclusive found in adolescents. The incidence rate of PPPD was higher in adolescents than in preschool and school-age children. Children with vertigo had good prognosis in general. Conclusions: VMC, RVC and SOM are the most common causes in vertigo in children, and their proportion was different in different aged children. Transforming abstract feelings into specific information is the skill required for collecting medical history of children with vertigo. Considering the age and cooperation of children, appropriate hearing and vestibular examination techniques are recommended. We should pay more attention to the mental health of children with vertigo and their parents.

OBJECTIVE: The purpose of this study was to evaluate the value of asymmetry values, gain, and pathological saccades of the video head impulse test (vHIT) in sudden sensorineural hearing loss (SSNHL). STUDY DESIGN: Retrospective study. SETTING: Tertiary referral center. PATIENTS: A total of 226 individuals diagnosed with unilateral definite SSNHL were hospitalized. The assessment included a comprehensive evaluation of medical history, pure-tone test, acoustic impedance, positional test, video nystagmography (VNG), vHIT, vestibular evoked myogenic potentials (VEMPs) and magnetic resonance. INTERVENTIONS: vHIT, VNG, cVEMP, oVEMP. Statistical analysis was performed with SPSS version 22.0 for Windows. MAIN OUTCOME MEASURES: The asymmetry values, gain, and pathological saccades of the vHIT. RESULTS: The abnormal gain of vHIT in anterior, horizontal, and posterior canal in SSNHL patients with vertigo were revealed in 20 of 112 (17.9%), 24 of 112 (21.4%), and 60 of 112 (53.6%), respectively. The vHIT pathological saccades (overt + covert) of anterior, horizontal, and posterior canal in SSNHL patients with vertigo were observed in 5 of 112 (4.6%), 52 of 112 (46.4%), and 58 of 112 (51.8%), respectively. Multivariate analysis indicated that the prognosis of patients with vertigo was correlated with vHIT gain of posterior canal, pathological saccade in horizontal canal, asymmetric ratio of horizontal canal gain, asymmetric ratio of posterior canal gain, Canal paresis (%) on caloric test and spontaneous nystagmus. CONCLUSION: In the vHIT of patients with SSNHL with vertigo, the posterior canal is most easily affected. Reduced gain of posterior canal, pathological saccade of horizontal canal, and larger asymmetric gain of posterior canal and horizontal canal may be negative prognostic factors.

OBJECTIVE: We used simple variables to construct prognostic prediction ensemble learning models for patients with sudden sensorineural hearing loss (SSNHL). STUDY DESIGN: Retrospectively study. SETTING: Tertiary medical center. PATIENTS: 1,572 patients with SSNHL. INTERVENTION: Prognostic. MAIN OUTCOME MEASURES: We selected four variables, namely, age, days after onset of hearing loss, vertigo, and type of hearing loss. We also compared the accuracy between different ensemble learning models based on the boosting, bagging, AdaBoost, and stacking algorithms. RESULTS: We enrolled 1,572 patients with SSNHL; 73.5% of them showed improving and 26.5% did not. Significant between-group differences were noted in terms of age ( p = 0.011), days after onset of hearing loss ( p < 0.001), and concurrent vertigo ( p < 0.001), indicating that the patients who showed improving to treatment were younger and had fewer days after onset and fewer vertigo symptoms. Among ensemble learning models, the AdaBoost algorithm, compared with the other algorithms, achieved higher accuracy (82.89%), higher precision (86.66%), a higher F1 score (89.20), and a larger area under the receiver operating characteristics curve (0.79), as indicated by test results of a dataset with 10 independent runs. Furthermore, Gini scores indicated that age and days after onset are two key parameters of the predictive model. CONCLUSIONS: The AdaBoost model is an effective model for predicting SSNHL. The use of simple parameters can increase its practicality and applicability in remote medical care. Moreover, age may be a key factor influencing prognosis.

OBJECTIVE: This study aimed to identify the potential subgroups of migraines based on the patterns of migraine associated symptoms, vestibular and auditory symptoms using latent class analysis and to explore their characteristics. METHOD: A total of 555 patients with migraine participated in the study. Symptoms such as nausea, vomiting, photophobia, phonophobia, osmophobia, visual symptoms, vestibular symptoms (dizziness, vertigo), and auditory symptoms (tinnitus, hearing loss, aural fullness) were assessed. Latent class analysis was performed to identify subgroups of migraines. Covariates such as gender, age of migraine onset, frequency of migraine attacks per month, and family history were also considered. RESULTS: The analysis revealed four latent classes: the Prominent Vestibular; Prominent Nausea; Presenting Symptoms but not prominent or dominant; and Sensory Hypersensitivity groups. Various covariates, such as gender, age of migraine onset, and frequency of migraine attacks, demonstrated significant differences among the four groups. The Sensory Hypersensitivity group showed the presence of multiple sensory symptoms, earlier age of migraine onset, and higher proportion of females. The Prominent Vestibular group had the highest probability of dizziness or vertigo but lacked the presence of auditory symptoms. The Prominent Nausea group exhibited prominent nausea. The Presenting Symptoms but not prominent or dominant group comprised individuals with the highest migraine attacks per month and proportion of chronic migraine. CONCLUSION: This study identifies four subgroups of migraines based on the patterns of symptoms. The findings suggest potential different but overlapped mechanisms behind the vestibular and auditory symptoms of migraine. Considering the different patterns of migraine-related symptoms may provide deeper insights for patients' prognosis and clinical decision-making.

INTRODUCTION: This study aimed to evaluate the prevalence and psychometric properties of vertigo and dizziness in an obstructive sleep apnoea (OSA) population. METHODS: Five hundred and twelve OSA patients and 53 controls were enroled. All eligible subjects were asked to complete the basic information questionnaire, the Chinese version of Vestibular Disorders Activities of Daily Living (VADL-C), the Dizziness Handicap Inventory (DHI) and the Activities-Specific Balance Confidence (ABC) scale. RESULTS: Among 512 enroled OSA patients, a 22.46% (115) prevalence of vertigo and dizziness was found. The scores of the VADL-C, DHI and ABC of the study group were significantly worse (p < .001) than those of the control group, while the abnormal rates of the three scales in the study group were higher than those of the control group. In the study group, the results of the VADL-C were correlated with those of the DHI (r = .55, p < .001) and inversely correlated with those of the ABC (r = -.50, p < .001), and the results of the DHI were inversely correlated with those of the ABC (r = -.60, p < .001). CONCLUSIONS: A high prevalence of vertigo and dizziness in the OSA population was detected. Psychometric results showed that vertigo and dizziness in OSA patients led to changes in activities of daily living, increased frequency of somatic symptoms, and reduced balance confidence. In the diagnosis and treatment of OSA patients, the occurrence of vertigo and dizziness is worth clinicians' attention.

PURPOSE: To review the vestibular, aural, and perceptual symptoms of vestibular migraine (VM) that may present alongside vertigo. RECENT FINDINGS: Increased research attention to the wide spectrum of symptoms presenting in VM patients has improved understanding of this disorder, with recent identification of five different VM phenotypes. Research into the clinical overlap between VM and other chronic vestibular syndromes such as persistent postural-perceptual dizziness and mal-de-debarquement syndrome reveals a range of vestibular symptoms and hints at pathophysiological connections between migraine and vestibular dysfunction. Studies of migraine treatment for hearing loss suggest patients presenting with aural symptoms may have an underlying diagnosis of migraine and deserve a trial of migraine preventives. Research into the neurologic basis of the perceptual disorder Alice in Wonderland syndrome has revealed brain areas that are likely involved and may help explain its prevalence in VM patients. VM is a sensory processing disorder that presents with more than just vertigo. Understanding the range of potential symptoms improves diagnosis and treatment for migraine patients whose diagnosis may be missed when only the symptoms identified in the diagnostic criteria are considered.

RATIONALE: Bilateral vestibulopathy is an important cause of imbalance. There are multiple etiologies of bilateral vestibulopathy (BVP), but reports of BVP due to otosyphilis are rare. PATIENT CONCERNS: A 39-year-old male was referred to our medical center due to vertigo, persistent dizziness and gait disturbance for 2 months. DIAGNOSES: Bilateral vestibulopathy due to otosyphilis was considered in this case, as confirmed through analyses of vestibular function, laboratory tests, and penicillin treatment. INTERVENTIONS: The patient was was treated with a high dose of penicillin G (24â ×â 106 IU/d) for 14 days. OUTCOMES: The patient's symptoms had improved greatly following treatment, with dizziness and gait disturbance having completely resolved at 3 months following hospital discharge. LESSONS: Bilateral vestibulopathy should be considered when evaluating patients with acute or subacute persistent dizziness. Clinicians should also be aware of the potential for otosyphilis among patients who report BVP.

INTRODUCTION: Persistent postural-perceptual dizziness (PPPD) and vestibular migraine (VM) share symptoms of visual vertigo and motion sickness that can be confusing for clinicians to distinguish. We compare the severity of these symptoms and dynamic subjective visual vertical (dSVV) in these two common vestibular conditions. METHOD: Twenty-nine patients with PPPD, 37 with VM, and 29 controls were surveyed for subjective symptoms using the visual vertigo analogue scale (VVAS) and motion sickness susceptibility questionnaire during childhood (MSA) and the past 10 years (MSB). dSVV is a measure of visual dependence measures perception of verticality against a rotating background (5 deg./s). RESULTS: VVAS revealed contextual differences for dizziness between those with PPPD and VM. Ratings of visual vertigo were most severe in PPPD, less in VM, and mild in controls (VVAS PPPD 27.1, VM 11.2, control 4.6, p < 0.001). MSA was more severe in VM than in PPPD or control (12.8 vs 7.6 vs 8.5, p = 0.01). MSB was more severe in VM than controls (MSB score 12.9 VS 8.1 p = 0.009) but was not different than PPPD (MSB score 10.0, p = 0.10). dSVV alignment was similar among the three groups (p = 0.83). Both VM and PPPD groups had greater simulator sickness than controls after completing the dSVV. CONCLUSIONS: Patients with PPPD report more visual vertigo than those with VM, but a history of motion sickness as a child is more common in VM. Additionally, the environmental context that induces visual vertigo is different between PPPD and VM.

Introduction: Vitamin B1 deficiency poses a significant risk of impaired consciousness, with manifestations ranging from anorexia and fatigue to severe neurological and cardiovascular disturbances. Wernicke's encephalopathy, a neurological disorder stemming from vitamin B1 deficiency, presents as the triad of ophthalmoplegia, altered mental state, and cerebellar ataxia. However, these symptoms are not consistently present, complicating the diagnosis. In addition, subclinical vitamin B1 deficiency can progress unnoticed until severe complications arise. Studies indicate a high rate of undiagnosed cases, emphasizing the need for early detection and intervention. Case presentation: We present the case of a 65-year-old man in whom hyperlactatemia was incidentally detected, leading to the diagnosis of vitamin B1 deficiency. The patient, presenting with vertigo and vomiting, had been eating boxed lunches bought from convenience stores following the death of his wife 3 years earlier. Vertigo gradually improved with rest, but the persistence of hyperlactatemia prompted further investigation, revealing low vitamin B1 levels and high pyruvate levels. Treatment with dietary adjustments and supplements significantly improved his symptoms. Discussion: In this case, hyperlactatemia was found in a vertigo patient, revealing asymptomatic vitamin B1 deficiency. Elevated lactate is often linked with conditions like sepsis but can also stem from overlooked factors such as low vitamin B1 levels due to poor diet habits like consuming fried foods. Conclusion: This case highlights the importance of considering vitamin B1 deficiency in patients with unexplained hyperlactatemia, even in high-income countries. Early detection can prevent progression to the severe complications associated with Wernicke's encephalopathy. Proactive measurement of lactate levels in at-risk populations may facilitate early diagnosis and intervention, ultimately improving patient outcomes.

BACKGROUND: Patients presenting to the emergency department with acute vertigo pose a diagnostic challenge. While 'benign' peripheral vestibulopathy is the most common cause, the possibility of a posterior circulation stroke is paradoxically the most feared and missed diagnosis in the emergency department. OBJECTIVES: This review will attempt to cover the significant advances in the ability to diagnose acute vertigo that have occurred in the last two decades. The review discusses the role of neurological examinations, imaging and specific oculomotor examinations. The review then discusses the relative attributes of the Head Impulse-Nystagmus-Test of Skew plus hearing ('HINTS+') examination, the timing, triggers and targeted bedside eye examinations ('TiTrATE'), the associated symptoms, timing and triggers, examination signs and testing ('ATTEST') algorithm, and the spontaneous nystagmus, direction, head impulse testing and standing ('STANDING') algorithm. The most recent technological advancements in video-oculography guided care are discussed, as well as other potential advances for clinicians to look out for.

BACKGROUND: Differential diagnosis of acute vertigo syndrome is challenging given the similarities between clinical presentations of posterior circulation stroke and peripheral vestibular dysfunction. The Head Impulse, Nystagmus, Test of Skew ('HINTS') assessment is a clinical bedside test used to aid diagnosis. METHODS: Comprehensive training on use of the Head Impulse, Nystagmus, Test of Skew assessment was provided to one stroke consultant, and the effectiveness of the test in that setting was assessed. Further education was completed with more members of the stroke and emergency department multi-disciplinary team. Quality improvement measures including magnetic resonance imaging use and bed utilisation were explored. RESULTS: Following training of one stroke consultant, the Head Impulse, Nystagmus, Test of Skew assessment was found to be a feasible, accurate bedside test within this acute stroke service. Further training for the multi-disciplinary team was completed, but outcome measures were not explored because of the coronavirus disease 2019 pandemic and maternity leave. CONCLUSION: There is a role for trained members of the multi-disciplinary team to successfully use the Head Impulse, Nystagmus, Test of Skew assessment in hyperacute stroke settings, to aid diagnosis in acute vertigo syndrome.

PURPOSE OF REVIEW: To provide an update on comorbidity of vestibular symptoms and migraine. RECENT FINDINGS: Multisensory processing and integration is a key concept for understanding mixed presentation of migraine and vestibular symptoms. Here, we discuss how vestibular migraine should be distinguished from a secondary migraine phenomenon in which migraine symptoms may coincide with or triggered by another vestibular disorder. We also have some updates on the diagnostic criteria of vestibular migraine, its pathophysiology, and common approaches used for its treatment. As a common clinical presentation of migraine and vestibular symptoms, vestibular migraine should be distinguished from a secondary migraine phenomenon, in which migraine symptoms may be triggered by or coincide with another vestibular disorder. Recent experimental evidence suggests vestibular symptoms in vestibular migraine are linked to multisensory mechanisms that control body motion and orientation in space.

Refractory vertigo is a disease entity characterized by uncontrollable recurrent vertigo and/or persistent dizziness instability, which can be caused by various diseases. The main pathogenesis may be related to recurrent episodes of the primary disease and compensatory dysfunction of the vestibular system. Understanding the common causes and pathological mechanisms of refractory vertigo, and comprehensively analyzing the relevant factors that cause symptoms, can facilitate accurate diagnosis and effective differentiation, and then provide comprehensive treatment targeting various factors such as etiology, symptoms, functional status, and psychological problems, ultimately achieving the goal of controlling the occurrence and development of refractory vertigo. Based on the characteristics of symptoms, this article focuses on analyzing possible mechanisms, relative factors, diagnosis and differential diagnosis of common diseases that lead to refractory vertigo, effective coping strategies, key issues that need attention, and future prospects, in order to improve clinical diagnostic accuracy and treatment effectiveness.
