Benign paroxysmal positional vertigo

Background and Aim: Benign paroxysmal positional vertigo (BPPV) is most common type of vertigo in general population. Epley maneuver is the most effective treatment technique. However, there is no clinically valid test to verify effectiveness of maneuver quickly after treatment in the same session. Modified clinical test of sensory interaction on balance (mCTSIB) is considered as a quick and simple test. This study aimed to use mCTSIB for assessing effectiveness of Epley maneuver in BPPV patients. Methods: The study was carried out on 44 patients (36 female and 8 male, mean age of 53.11 (SD=7.09) diagnosed with posterior semi-circular canals BPPV in Dix-Hallpike test and no other vestibular disorders. mCTSIB in four conditions was assessed, before and after Epley maneuver. Balance time, lateral and anterior-posterior sway were recorded. mCTSIB repeated after three weeks to assess reliability. Results: The time for balance control in mCTSIB after maneuver did not change significantly relative to before maneuver (p>0.05). Lateral sway changes in conditions 2, 3 and 4 in mCTSIB significantly reduced after maneuver

Patients with severe major depression most commonly undergo electroconvulsive therapy (ECT). Although this procedure is usually safe and the complication rates are very low, some side-effects and medical complications are observed. The reported adverse effects are generally minor in severity, and vertigo is one of these complications. We presented a case of benign paroxysmal positional vertigo (BPPV) occurring after ECT and aimed to discuss the pathophysiological mechanism of this condition. To the best of our knowledge, there are no other case reports regarding the co-occurrence.

The vestibulo-ocular reflex was studied at high frequencies of active head rotation (2 to 6 Hz) in twenty-three patients with benign positional vertigo (BPPV). Gain and phase measurements were obtained in the vertical and horizontal planes, and the results were compared to those of a control group consisting of 19 asymptomatic age-matched subjects. In the horizontal plane, the phase lead was significantly smaller in patients with BPPV as compared to controls (p < 0.01 at all frequencies). Vertical results did not differ from normals. These findings challenge "cupulolithiasis" as an explanation of the mechanism of BPPV's symptoms.

This is the first case to our knowledge of a serious adverse event following the Epley maneuver, which is the treatment of choice for benign paroxysmal positional vertigo (BPPV), the most common vestibular disorder in adults. A 77 year old female presented for outpatient evaluation of vertigo at a tertiary otolaryngology clinic. She was found to have BPPV clinically, and elected to have a particle repositioning maneuver (Epley maneuver) performed in clinic. Immediately following Epley maneuver, she had severe nausea and vomiting, with evolving visual changes. A CT angiogram of the brain was performed urgently through the emergency department and demonstrated an acute intraparenchymal hemorrhage in the occipital lobe. After medical stabilization and rehabilitation, the patient continues to have a permanent visual field deficit. The Epley maneuver is safe and effective, and there are no prior reports of serious adverse events associated with its use. This case, in which a patient expe...

This retrospective study was conducted to determine the relationship between variable factors and the recurrence rate of post-semicircular canal benign paroxysmal positional vertigo (PSC-BPPV) after canalith repositioning procedure (CRP). Patients with PSC-BPPV were diagnosed by history and the presence of a positive Dix-Hallpike maneuver between 2008 and 2010. In total, 243 patients (47 males and 196 females, average age = 57.5 years) treated with Epley's maneuver or canalith repositioning procedure (CRP) were included in the study. The demographic factors studied were age, sex, sleep disorders, inner ear diseases, head trauma history, and cardiovascular diseases. Multivariate statistics using SPSS version 15, Pearson's Chi-squared test (χ (2)), Kaplan-Meier analysis, log-rank test, and Cox proportional hazards regression model were used for the analysis. The success rate of vertigo control after the initial CRP was 83.1 %. Pearson's χ (2) test results showed that femal...

AIM To determine the importance of accurate topological diagnostics of the otolith and the differentiation of certain clinical forms of benign paroxysmal positional vertigo (BPPV). METHODS A prospective study was conducted at the County General Hospital Vukovar in the period from January 2011 till January 2012. A total of 81 patients with BPPV, 59 females (72.84%) and 22 (27.16%) males (p less than 0.001), mean age 60.1 (± 12.1) were examined. The diagnosis was confirmed and documented by videonystagmography (VNG). The disability due to disease and risk of falling were monitored by filling in the Dizziness Handicap Inventory (DHI) and Activities-specific Balance Confidence Scale (ABC) questionnaires at the beginning and at the end of the repositioning treatment. RESULTS In 79 (97.3%) patients posterior semicircular canal was affected, and in a small number of patients, two (2.47%) the lateral one. After the repositioning procedures were performed, there was a significant reduction o...

Results: 42 patients (61%) were referred through the conventional route (primary healthcare or non-hospital ENT); 17 patients (25%) came from the emergency room (one third of them were admitted); the remainder were patients hospitalized for some other problem (5%) or ...

Introduction Benign paroxysmal positional vertigo (BPPV) is the most common type of vertigo. It is frequently seen in elderly patients, and the course of the attack may easily mimic cerebrovascular disease. A BPPV attack after a radiologic examination has not been reported previously. We report the cases of two patients who had BPPV attacks after radiologic imaging. Case presentation The first patient with headache and tremor was admitted to the radiology department for cranial computed tomography (CT) imaging. During scanning, she was asked to lie in the supine position with no other head movements for approximately 10 minutes. After the cranial CT imaging, she stood up rapidly, and suddenly experienced a vertigo attack and nausea. The second patient was admitted to the radiology department for evaluation of his renal arteries. During the renal magnetic resonance angiography, he was in the supine position for 20 minutes and asked not to move. After the examination, he stood up rapi...

Objective To determine the rate of symptom resolution in patients with posttraumatic benign paroxysmal positional vertigo (BPPV) and to determine if it differs from resolution rates in patients with BPPV and without a history of head trauma. Data Sources Systematic review of the literature was performed using Medline, EMBASE, and Cochrane databases. English and French articles meeting inclusion criteria and published between 1946 and October 2014 were included. Review Methods Data were independently extracted from the articles by 2 reviewers using data collection forms developed a priori. Inclusion and exclusion criteria were decided a priori. Studies were included if they reported on at least 1 case of posttraumatic BPPV (t-BPPV), reported on outcomes of all patients with t-BPPV, had a clearly defined inception point, and provided a clear diagnosis of BPPV (defined a priori by reviewers). Results A total of 3017 titles, 362 abstracts, and 67 articles were reviewed, from which 16 ar...

There is evidence suggesting that migraine may be associated with vertigo. The aim of this study was to assess the risk of benign paroxysmal positional vertigo (BPPV), the most common form of vertigo, in patients with migraine using a population-based dataset. The National Health Insurance Research Database in Taiwan was searched for migraine patients and was also used to select an age- and sex-matched cohort of subjects without migraine. The analyses included 8266 migraine patients and 8266 controls. The incidence rates of BPPV in the two cohorts were compared. Cox proportional hazard models were used to identify risk factors for BPPV in migraine patients. In the migraine cohort, 1.11 % of the patients developed BPPV compared to 0.5 % of the controls. The incidence rate ratio was 2.03 (95 % CI 1.41-2.97; p <0.001). Cox proportional hazards analysis showed that age ≥40 years (HR 2.20; 95 % CI 1.40-3.45; p = 0.001), coronary artery disease (HR 4.62; 95 % CI 1.12-19.01; p = 0.034),...

Benign paroxysmal positional vertigo (BPPV) is one of the most common balance disorders of the peripheral vestibular system. Diagnosis is made from patient history and the manifestation of specific symptoms. Treatment differs for the individual patient and may include pharmacological, surgical, dietary, and/or therapeutic modalities. Various versions of Modified Liberatory Maneuvers (MLM), and other, similar rehabilitation therapy treatments have been shown to be very effective in the management of the BPPV patient.

In this study the relationship of serum homocysteine, vitamin B12, folic acid levels and peripheral vestibular dysfunction (PVD) was investigated. Forty-one patients (31 females, 10 males; mean age 57.34±14.3 years; range 12 to 80 years) who admitted to Baskent University Hospital Ear Nose and Throat Department between the dates of April 2005 - December 2007 with complaint of vertigo were prospectively analyzed and diagnosed using audio-vestibular test, at the same time serum homocysteine, vitamin B12, folic acid measurements was done from the blood samples of patients. The patients were divided into three groups as Meniere's disease, vestibular neurinitis, and benign paroxismal positional vertigo (BPPV) according to the diagnoses and serum homocysteine, vitamin B12, folic acid levels of patients were compared to normal values in and between groups. Of the patients, 29.3% (n=12) were diagnosed with Meniere's disease, 36.6% (n=15) with vestibular neurinitis, and 34.1% (n=14) ...

Introduction: To identify the type of referrals received by vestibular physiotherapists for vertigo and assess whether medical review for these patients would be appropriate. Materials and Methods: We performed a retrospective review of referral forms, vestibular assessment forms, and vertigo clinic letters of patients referred for vertigo or vestibular physiotherapy input between Results: We studied 29 patients with a median age of 63 years. A diagnosis was provided in 65.5% of the referrals. Of 14 patients with possible benign paroxysmal positional vertigo (BPPV), Dix-Hallpike had been performed only for 4 patients. Almost half were seen for the medical review in the Vertigo Clinic due to the concerns of possible alternative non-vestibular diagnosis, medication issues, or syncope. Alternative diagnoses identified medically included orthostatic hypotension, stroke, vestibular migraine, medication-induced bradycardia, and phobic postural vertigo. Medication changes in vertigo clinic included treatment for heart failure, migraine, and medication optimization. Conclusion: Medical review is appropriate for some patients referred for vestibular physiotherapy. A medical opinion should be sought by vestibular physiotherapists if there is uncertainty or concerns that the referred patients did not have straightforward vestibular problems, or there were possible alternative diagnoses, concerns with medications, or syncope.

To clarify the pathophysiological basis of persistent geotropic positional nystagmus (PGN) in patients with the horizontal canal type of benign paroxysmal positional vertigo (H-BPPV), the time constant (TC) of nystagmus and the relationship between its slow phase eye velocity (SPV) and the angle of head rotation in supine were defined. Geotropic or apogeotropic positional nystagmus was recorded by video-oculography and analysed three-dimensionally. Geotropic positional nystagmuses in patients with H-BPPV were classified as transient geotropic positional nystagmus with a TC of ≤35 s or PGN with a TC of >35 s. Alternatively, the TC of persistent apogeotropic positional nystagmus (AN) in patients with H-BPPV was >35 s. The direction of the SPV of patients with PGN was opposite to that of patients with AN at each head position across the range of neutral head positions. The relationship between the SPV of patients with PGN and the angle of head rotation was linearly symmetrical ag...

The aim of this study was to adapt the Vertigo Symptom Scale (VSS) and the Vertigo Dizziness Imbalance (VDI) Questionnaires to the Turkish population and investigate the reliability and validity of the Turkish version. One hundred and three patients with Benign Paroxysmal Positional Vertigo (BPPV) were included in the study. The patients were evaluated with the VSS and the VDI twice, at recruitment and 24 hours later. To perform concurrent validity study study, patients were also assessed by the Beck Depression Inventory (BDI) and the Medical Outcomes Survey Short Form 36 (SF-36) which were formerly proved to be valid and reliable for use in Turkish population. The internal consistency of the VSS, VDI-symptom scale, and VDI-health-related quality of life scale were good with Cronbach's alpha of 0.91, 0.85, and 0.93 respectively which showed high reliability for the Turkish versions. Test-retest reliability was also good, with a high intraclass correlation coefficent (ICC) betwee...

BACKGROUND More than 50% of the patients with peripheral vestibular disorders are suffering from Benign Paroxysmal Positional Vertigo (BPPV). Diagnosis is established by positive Dix-Halpike test and/or roll test. Objective of this study was to analyse the delay in diagnosis and treatment of BPPV in current practice and to suggest measures to avoid this delay. METHODS One hundred and fifty two consecutive patients who were diagnosed and treated for BPPV in ENT department CMH Rawalpindi from Jan 2009 to Sep 2011 were selected for this study. All these patients were interviewed in detail regarding duration of vertigo, associated symptoms, visits to hospitals, investigations, treatment taken, cost of treatment and last or referral diagnosis before coming to our department. RESULTS Out of 458 patients who presented with vertigo, 152 (33.2%) fulfilled the diagnostic criteria of BPPV. Male to female ratio was 1:1.17. Age range was 13-80 years and mean age 58.2 +/- 12.6. Posterior canal wa...

In this paper, the treatment by medication together with two maneuvers-the particle repositioning maneuver (PRM) reported by Parnes and Price-Jones and the liberatory maneuver (LM) reported by Semont et al.-were compared with treatment by medication alone. Fourteen of 15 cases (93.3%) treated with the PRM and 11 of 14 cases (78.6%) treated with the LM showed improvement after 2 weeks. These results were better than that obtained by medication alone, in which 8 of 26 cases (30.8%) showed improvement after 2 weeks. The most important benefit of these maneuvers seemed to be the speedier recovery than with medication alone, as there was no significant difference in the late success rate after 3 months between the maneuvers and medication alone.

BPPV is generally the most common cause of vertigo, caused by a pinch-off of tiny calcium carbonate crystals (called the otoconia or the otoliths) from the macula utriculi, most frequently due to the degenerative processes or a trauma, whereby the crystals, under the action of gravity in certain head positions coinciding with its direction, arrive to some of the semicircular canals, usually the posterior one, due to the existent anatomical circumstances and relationships, thus creating an inadequate stimulus of the cupular senses while floating through the endolymph and provoking symptoms of a strong and short-term dizziness. Two main clinical forms can be distinguished: canalolythiasis, with an accommodation of otolithic debris in the semicircular canal, and cupulolythiasis, with their location immediately next to the cupular sense. The diagnosis is established by a positive positioning test, Dix-Hallpike for the posterior and the supine roll for the lateral canal. Although one can...

Introdução: A vertigem postural ou posicional paroxística benigna (VPPB) é uma síndrome muito comum na prática clínica, pode ter etiologia diversa e seu tratamento baseia-se principalmente em manobras de reposição canalicular. Entretanto, algumas doenças do sistema nervoso central mimetizam a VPPB e precisam ser descartadas antes do diagnóstico da síndrome. Forma de Estudo: Relato de caso e revisão de literatura. Objetivo: Alertar os otorrinolaringologistas para maior investigação diante de sinais suspeitos de vertigem posicional não-benigna e discutir o manejo diante de uma revisão de literatura. Relato: Paciente de 43 anos, masculino, com queixa de tonturas rotatórias há três anos com evolução em crises principalmente ao deitar em decúbito lateral esquerdo e ao virar a cabeça para a esquerda. A prova de Dix-Hallpike mostrou-se positiva para a esquerda, sugerindo canalilitíase de canal semicircular posterior. A manobra de reposição de Epley resultou em desaparecimento das vertigens...

To determine the recurrence rate of benign positional paroxysmal vertigo (BPPV) and the factors associated to such recurrences. Prospective study. Sixty-nine consecutive patients treated for first episode of BPPV. 63 months. Mean follow-up: 47 months. The recurrence rate was 27%. Fifty percent of recurrences occurred in the first 6 months. Nineteen patients had 1 or more recurrence of BPPV; 10 had 1 recurrence, 7 patients had 2, and 2 patients had 3 recurrences. There was no significant difference in the recurrence rate according to sex, age, side, cause of BPPV, or instability after successful treatment. Multi-canal BPPV (log-rank, p = 0.024) and anterior canal BPPV (log-rank, p = 0.029) showed a significantly greater tendency to recur and to do so earlier. There was a significant difference in time to recurrence related to the number of maneuvers used to resolve the initial BPPV episode (log-rank, p = 0.023). Except for cases of BPPV secondary to labyrinthitis or neurolabyrinthitis, at least 70% of the recurrences affected a different side and/or different canal than the primary BPPV. The recurrence rate of BPPV is 27%, and relapse largely occurs in the first 6 months. When BPPV recurrence is suspected, every canal on both sides must be investigated because it is the BPPV syndrome that recurs, rather than BPPV affecting a particular side or canal. Complex cases of BPPV have a greater risk of recurrence.

To study the demographic, clinical, pathogenetic, and nystagmographic features and treatment outcomes of subjective benign paroxysmal positional vertigo (BPPV). Prospective clinical trial. Tertiary referral center. Sixty-three patients were studied (mean [SD] age 55.4 [9.4] years), 27 men and 36 women, who presented with a positive history for BPPV and Dix-Hallpike or supine roll tests positive for vertigo but negative for nystagmus. A comprehensive history was obtained, followed by clinical examination of the ears, nose, and throat and a complete audiologic and neurotologic examination, including videonystagmography. All patients were treated with the appropriate canalith repositioning procedure, depending on the type of provoking positioning test. A group of 204 patients with typical BPPV were used for comparison. Forty-five patients with subjective BPPV were successfully treated. Eighteen patients, in most of whom vertigo of other causes was identified, did not respond to treatment. Comparison between patients with subjective and typical BPPV showed similar epidemiological and clinical features. Treatment failed in 13.5% of patients with subjective disease, after excluding patients with different causes of positional vertigo, as compared with 7.8% of patients with typical BPPV (odds ratio = 1.8; 95% confidence interval, 0.7-4.7; P = .32). Subjective BPPV is quite common, accounting for more than one-fourth of patients with typical BPPV and sharing common features with it, with the exception of nystagmus. No statistical difference in treatment outcomes between patients with subjective and typical BPPV was found, but study of a larger sample is needed.
