Objective: To investigate the diagnosis strategy of anterior canal-benign paroxysmal positional vertigo (AC-BPPV) and the therapeutic effects of the Yacovino maneuver.

Methods: The clinical data of 40 AC-BPPV patients were collected. The nystagmus characteristics induced by the Dix-Hallpike (D-H) and straight head-hanging (SHH) tests, the diagnostic methods used, and the effectiveness of the Yacovino maneuver for the treatment of AC-BPPV were all retrospectively analyzed.

Vestibular migraine probably represents the second most common cause of vertigo after benign positional vertigo, by far exceeding Ménière disease. There are still relatively few published reports on vestibular migraine management, despite its enormous importance in daily practice. In 2003 the first clinical definition of vestibular migraine was proposed. Read More

Background This study aimed to evaluate serum 25-hydroxy vitamin D (25 (OH) D) levels in Chinese patients with idiopathic benign paroxysmal positional vertigo (BPPV) and to investigate the possible relationship between the occurrence and recurrence of idiopathic BPPV and low 25 (OH) D levels. Methods Between January 1, 2017, and May 31, 2018, consecutively older patients (age, older than 50 years) with idiopathic BPPV were recruited in this study. For each patient, 2:1 sex and age matched healthy people were assigned as the control group. Read More

Background: Several studies have shown that the incidence of benign paroxysmal positional vertigo (BPPV) presents seasonal variations and there is evidence that the variation in time is dependent on the patient's amount of vitamin D.

Objectives: This is a retrospective study to verify if there is a correlation between the incidence of BPPV and the level of solar radiation, essential for the synthesis of vitamin D in the skin.

Material And Methods: This study comprised 214 patients with BPPV seen from 2012 to 2017, in a city Latitude: -30. Read More

 Benign paroxysmal positional vertigo (BPPV) is the most common form of peripheral vertigo, and, in most cases, it presents a favorable prognosis. The treatment is based on a series of specific canalicular repositioning maneuvers that offer an efficacy close to 100%. Despite this, there are cases that are refractory to treatment, with the persistence of the vertigo symptoms. Read More

Aging in vestibular structures with loss of hair cells in the inner ear starts early in life, but vestibular function usually remains relatively unimpaired up to advanced ages. However, dizziness and imbalance are common in the elderly and have substantial impact on the quality of life. Dizziness interferes with the everyday activities of 30% of persons over age 70.

Purpose of Chapter: This chapter discusses the recent progress made in understanding the pathophysiology, diagnosis, and treatment of benign paroxysmal positional vertigo (BPPV). Recent Findings: Recent evidence supports the canalolithiasis model as the pathophysiological mechanism and predominant subtype of BPPV. Scanning electron micrographs of extracted posterior semicircular canal contents show free-floating otoconia of utricular origin. Read More

Objectives: This study aimed to investigate the rate of dizziness and occurrence of benign paroxysmal positional vertigo in the elderly by physical examination in those reporting dizziness symptoms when lying down or turning over in bed.

Methods: A total of 498 people, aged 70-85 years, were asked to complete a questionnaire regarding dizziness symptoms. Subjects answering that they became dizzy in bed were asked to participate in a physical examination and diagnostic manoeuvres investigating benign paroxysmal positional vertigo. Read More

Background And Purpose: Although acute attacks of benign paroxysmal positional vertigo (BPPV) may be treated with canalith repositioning maneuvers, there have been no well-designed prospective trials to prevent this highly prevalent and recurrent disorder. This topical review explores the evidence related to the association between deficient calcium metabolism and BPPV. We also describe the development of therapeutic options to prevent recurrences of BPPV and introduce results from a recent randomized controlled trial on the effect of vitamin D and calcium supplementation in preventing BPPV recurrences.

Physical Therapy Program, Midwestern University, Downers Grove, Illinois.

Background And Purpose: Downbeat nystagmus (DBN) during the Dix-Hallpike test (DHT) suggests excitation of the anterior canal (AC) or inhibition of the posterior canal (PC) underlying benign paroxysmal positional vertigo (BPPV). This case series describes 2 individuals presenting with DBN in positional testing suggestive of a PC BPPV variant termed apogeotropic PC-BPPV and due to inhibition of the PC.

Case Descriptions: Case 1 illustrates a DBN during positional testing (PC inhibition) that changes to an upbeating nystagmus (PC excitation) representing the otoconial material changing location and direction of movement within the PC. Read More

In the horizontal canal benign paroxysmal positional vertigo (BPPV), cupulolithiasis shows apogeotropic direction changing nystagmus lasting more than 1 min, while canalolithiasis leads to geotropic direction changing nystagmus lasting < 1 min. The difference between cupulolithiasis and canalolithiasis is widely accepted to be the attachment of the displaced otoconia to the cupula of a semicircular canal. Several studies have shown a relationship between BPPV and vitamin D deficiency, but no studies have compared serum levels of vitamin D between canalolithiasis and cupulolithiasis patients.

Head trauma is the most frequent cause of benign paroxysmal positional vertigo (BPPV) in patients younger than 50 years, and finding the aetiology of post-traumatic dizziness can be challenging. This case report presents a 45-year-old male patient suffering from positional dizziness after head trauma. He was diagnosed in a reposition chair, after manual manoeuvres had failed to provide the diag-nosis. Read More

Acute vertigo is a common problem in emergency departments. However, clinical strategies of acute vertigo care vary among care providers. The aim of the study was to investigate differences in diagnosis [Dix-Hallpike test, the head impulse, nystagmus, and the test of skew (HINTS) procedure, and imaging modalities] and treatment (pharmacological treatments and the Epley maneuver) by otolaryngologists and non-otolaryngologists in emergency medicine settings.

Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo, which results from dislodged vestibular otoliths. Because the otoliths are mainly composed of calcium carbonate, it has been suggested that BPPV may be associated with osteoporosis. We aimed to assess the incidence and recurrence of BPPV in osteoporosis patients using a nationwide population-based cohort study with matched control. Read More

The objective of the present study was to meta-analyze relevant literature to gain a comprehensive understanding of the potential relationship between serum uric acid levels and risk of benign paroxysmal positional vertigo (BPPV). The databases of PubMed, Web of Science, Embase, Chinese National Knowledge Infrastructure, Wanfang, and SinoMed were systematically searched for observational case-control studies of the association between BPPV and serum uric acid levels published up to October 2018. Data from eligible studies were meta-analyzed using Stata 12. Read More

In a split victory, TMA once again prevailed in November 2018 when the Third Court of Appeals upheld a trial court's decision that chiropractors don't have the authority to perform vestibular-ocular-nystagmus testing (VONT). However, a recent change to state law caused the appeals court to find in the Texas Board of Chiropractic Examiners' favor on the use of the word "diagnosis" in the board's administrative rules - meaning chiropractors can diagnose, but only within their scope of practice.
