Dizziness is a common symptom and though most of the causes are benign yet some may be potentially life threatening. Diagnosis can be a challenge sometimes due to lack of dedicated vestibular lab and injudicious use of vestibular suppressant medications. A 2 year retrospective study of the hospital records from September 2014 to August 2016 was done to study the causes of dizziness and the limitations and challenges in the diagnosis. 75 complete records of patients presenting with dizziness were accessed and analysed...

The acute vestibular syndrome is common and usually has a benign cause. Sometimes, however, even experienced neurologists can find it difficult to determine the cause clinically. Furthermore, neuroimaging is known to be insensitive.We describe two cases of acute vestibular syndrome where conflicting clinical findings contributed to a delay in making the correct diagnosis. The first patient with symptomatic vertigo had signs consistent with horizontal benign paroxysmal positional vertigo but also had an abnormal horizontal head impulse test, superficially suggesting acute vestibular neuritis but later accounted for by the finding of a vestibular schwannoma (acoustic neuroma)...

Recent evidence has indicated that osteoporosis is a risk factor for benign paroxysmal positional vertigo (BPPV). This large population-based study demonstrated that patients with osteoporosis had a 1.82-fold higher risk of developing BPPV than those without osteoporosis through the use of the Taiwan National Health Insurance Research Database. PURPOSE: Benign paroxysmal positional vertigo (BPPV) is one of the most frequent causes of vertigo. Osteoporosis reflects a homeostatic imbalance in the rate of bone turnover, with the rate of bone resorption exceeding that of bone formation...

Paroxysmal Kinesigenic Dyskinesia (PKD) is a rare neurological disorder characterized by recurrent attacks of dyskinetic movements without alteration of consciousness that are often triggered by the initiation of voluntary movements. Whole exome sequencing has revealed a cluster of pathogenic variants in PRRT2 (proline-rich transmembrane protein), a gene with a function in synaptic regulation that remains poorly understood. Here, we report the discovery of a novel PRRT2 pathogenic variant inherited in an autosomal dominant pattern in a family with PKD and Benign Familial Infantile Seizures (BFIS)...

BACKGROUND: In clinical practice, nonepileptic paroxysmal events during infancy and childhood are common reasons for parents and caregivers to seek for medical advice. These events are mostly unrecognized and considered as an epileptic seizure because of the clinical features resembling an epileptic seizure. Paroxysmal tonic upgaze, which consists of recurrent episodes of sustained upward deviation of the eyes and incomplete downward saccades, and normal horizontal eye movements without impairment of consciousness, is a diagnostic challenge for the pediatrician and pediatric neurologist...

OBJECTIVE: To systematically review the evidence and make recommendations with regard to diagnostic utility of cervical and ocular vestibular evoked myogenic potentials (cVEMP and oVEMP, respectively). Four questions were asked: Does cVEMP accurately identify superior canal dehiscence syndrome (SCDS)? Does oVEMP accurately identify SCDS? For suspected vestibular symptoms, does cVEMP/oVEMP accurately identify vestibular dysfunction related to the saccule/utricle? For vestibular symptoms, does cVEMP/oVEMP accurately and substantively aid diagnosis of any specific vestibular disorder besides SCDS? METHODS: The guideline panel identified and classified relevant published studies (January 1980-December 2016) according to the 2004 American Academy of Neurology process...

Adults over the age of 70 are at risk of falls. Early detection of risk of falls can suggest early interventions. In this study, we attempted to determine valid clinical tests that can differentiate older individuals who are at risk of falling. Older adults from an independent-living community volunteered to participate in this descriptive, cohort study. They were administered the Berg Balance Scale (BBS), Zur Balance Scale (ZBS); Head Shaking Nystagmus Head Impulse Test, Dynamic Visual Acuity, and the Hallpike maneuver for evaluating benign paroxysmal positional vertigo (BPPV); a questionnaire including sociodemographics and a health characteristics survey...

Benign paroxysmal positional vertigo (BPPV) is the most common type of positional vertigo. A canalolithiasis-type of BPPV involving the lateral semicircular canal (LSCC) shows a characteristic direction-changing positional nystagmus (DCPN) which beats towards the lower ear (geotropic) on turning the head to either side in a supine position. Because geotropic DCPN in LSCC canalolithiasis is transient with a latency of a few seconds, the diagnosis can be challenging if geotropic DCPN is persistent without latency...

This article presents operational diagnostic criteria for benign paroxysmal positional vertigo (BPPV), formulated by the Committee for Classification of Vestibular Disorders of the Bárány Society. The classification reflects current knowledge of clinical aspects and pathomechanisms of BPPV and includes both established and emerging syndromes of BPPV. It is anticipated that growing understanding of the disease will lead to further development of this classification.
