BACKGROUND Benign paroxysmal positional vertigo (BPPV) is one of the most common and most successfully treated vestibular disorders. However, there is a lack of predictive factors for BPPV in clinical practice. We aimed to explore several possible predictive factors for BPPV in the Chinese population. MATERIAL AND METHODS We enrolled 240 patients with BPPV from Beijing Chaoyang Hospital between July 2013 and July 2016. Biochemical and hematological markers were obtained along with the history of cardiovascular and cerebrovascular diseases...

OBJECTIVE: Benign paroxysmal positional vertigo (BPPV) is characterized by recurrent episodes of positional vertigo due to dislodged otoconia debris within the semicircular canals. Many studies have proposed a correlation between Vitamin-D deficiency and recurrent BPPV. In the UK, serum Vitamin-D falls during the winter, reaching its lowest level in May and it is highest level in September. We hypothesize that if there is a relationship between BPPV and Vitamin-D levels, one would expect to see a seasonal variation in the incidence of BPPV among UK residents...

An immune attack by anti-glutamic acid decarboxylase (GAD) antibodies is believed to cause a deficiency in gamma-aminobutyric acid-mediated neurotransmission in the cerebellum. This, in turn, leads to several eye movement disorders, including spontaneous downbeat (DBN) and periodic alternating nystagmus. We describe a 68-year-old diabetic woman with disabling paroxysmal positioning upbeat nystagmus (UBN) exclusively in the supine position, associated with asymptomatic spontaneous DBN, alternating skew deviation and hyperactive vestibulo-ocular reflex responses on head impulse testing, in whom high titers of anti-GAD antibodies were detected...

OBJECTIVE: The non-criteria neuropsychiatric manifestations of antiphospholipid syndrome include headache, dizziness, vertigo, seizure, depression and psychosis. There were still no objective methods qualified to detect the early central nervous system involvement in non-criteria antiphospholipid syndrome. We evaluated the effectiveness of Tc-99m ECD SPECT in assessing circulatory insufficiency in the brains of patients with antiphospholipid antibodies and neuropsychiatric symptoms but without thromboembolism...

The objectives of this study is to compare the efficacy between repetition of Epley maneuver and switch to alternate Semont maneuver in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV) that does not respond to the initial Epley maneuver. In the nationwide, seven dizziness clinics of Korea, 506 consecutive patients (303 women, age range 22-87, mean age ± SD = 64 ± 12, median = 61) with idiopathic PC-BPPV were initially treated with a single Epley maneuver. Of those, 144 (28.5%) patients, who did not respond to the therapy, were randomized to the repetition of Epley maneuver (n = 70) or switch to Semont maneuver (n = 74)...

Psychogenic (functional) vertigo is in second place by frequency after benign positional paroxysmal vertigo. It is often difficult to make the diagnosis, diagnostic program is expensive and traditional treatment often is not effective. This literature review covers current concepts on the terminology, clinical signs, pathogenesis and treatment approaches with regard to functional vertigo. Special attention is given to cerebral mechanisms of the pathogenesis including cognitive aspects.

A 33-year-old male professional football player suffered from acute-onset dizziness following a lower limb soft tissue treatment in prone lying. Symptoms included spinning vertigo lasting for 30's, headache, visual vertigo and disorientation. Clinical examination of balance and vestibular systems confirmed a left posterior canalithiasis benign paroxysmal positional vertigo (BPPV) and excluded other central and peripheral causes of dizziness. Two cycles of a left Epley manoeuvre were performed. An Epley manoeuvre abolished the BPPV and negated the need for medication...

BACKGROUND: The traditional approach to dizziness encourages providers to emphasize the type of dizziness. However, symptom types might substantially overlap in individual patients, thus limiting the clinical value of this approach. We aimed to describe the overlap of types of dizziness using a United States nationally representative sample. METHODS: The 2008 US National Health Interview Survey was examined for prevalence and overlap of types of dizziness. The data was also separately examined among people who otherwise had typical features of traditionally vertigo-based disorders (i...

Benign paroxysmal positional vertigo (BPPV) is the most frequent type of vertigo. The treatment of canalithiasis of the posterior semicircular canal consists in performing a particle-repositioning maneuver, such as the Epley maneuver (EM). However, the EM is not effective in all cases. The objective of this study is to identify risk factors, which predict the EM failure, among the clinical variables recorded in anamnesis and patient examination. This is an observational prospective multicentric study. All patients presenting with BPPV were recruited and applied the EM and appointed for a follow-up visit 7 days later...

Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vestibular disorder, accounting for 20% of all vertigo cases. Idiopathic BPPV is most common between the ages of 50 and 70, although the condition is found in all age groups. This study was conducted in our institute on 90 patients who presented to the outpatient department with history of vertigo and were diagnosed with BPPV via a positive Dix Hallpike test. Patients were randomnly placed in three groups of 30 each. Patients in Group A were treated with Epleys manoeuvre alone, in Group B were treated with Epleys Manouvre followed by oral Betahistine and patients in Group C were treated with Betahistine alone...

OBJECTIVES: The clinical approach to acute vestibular syndromes is often complex for the physician. Neurosonology offers a noninvasive method to study the cervicocephalic circulation when a vascular etiology is suspected. We aim to evaluate the diagnostic accuracy of a vascular neurosonological exam in isolated acute vestibular syndrome. METHODS: All patients submitted to cerebrovascular ultrasound and magnetic resonance imaging during the period between 2011 and 2015 with acute isolated vestibular syndrome...

Anterior semicircular canal Benign Paroxysmal Positional Vertigo (antBPPV) is the rarest form of semicircular canalolithiasis, corresponding to about 1-2 % of the BPPV. The diagnosis is obtained by either the Dix-Hallpike maneuver or the straight head hanging positioning maneuver, which provoke a characteristic positional down-beating nystagmus. This vertical nystagmus can be associated with a torsional component that helps in localizing the affected side. The differential diagnosis of antBPPV includes the various central lesions that produce vertical down beating nystagmus (posterior fossa)...

Although several researchers have tried various canalith repositioning procedures for lateral canalolithiasis, a standard treatment has not been established. We adopt 120° rotation, which is anatomically appropriate because the principle of cure may be the fixing of pathological debris to the dark cells of the utricle. The aims of this study were to clarify the efficacy rate of the affected-ear-up 120° maneuver and to elucidate the appearance rate of lying-down nystagmus in patients with lateral canalolithiasis...
