Positional nystagmus of central origin.
Audiometric, electrophysiologic, and radiographic findings for a 68-year-old male with an "imbalance" concern are presented. This paper has a two-fold purpose: (1) to present an unusual electronystagmography case study and (2) to highlight the importance of test conditions in lesion localization. The specific disease pathophysiology remains obscure. Repeated hearing tests documented a known hea...
متن کاملSitting-up vertigo and trunk retropulsion in patients with benign positional vertigo but without positional nystagmus.
BACKGROUND Presently, the unambiguous diagnosis of benign paroxysmal positioning vertigo (BPPV) requires the detection of positioning or positional nystagmus provoked by Dix-Hallpike (for vertical semicircular canals) or supine roll (for horizontal semicircular canals) manoeuvres, which indicates canalo- or cupolithiasis of affected semicircular canals. There are patients, however, in whom--des...
متن کاملBenign paroxysmal positional vertigo without nystagmus: diagnosis and treatment.
UNLABELLED Nystagmus tests to diagnose BPPV are still relevant in the clinical evaluation of BPPV. However, in everyday practice, there are cases of vertigo caused by head movements, which do not follow this sign in the Dix-Hallpike maneuver and the turn test. AIM To characterize BPPV without nystagmus and treatment for it. MATERIALS AND METHODS A non-systematic review of diagnosis and trea...
متن کاملDown-beating nystagmus in anterior canal benign paroxysmal positional vertigo.
Down-beating positional nystagmus is typically associated with central nervous system disease. Anterior canal benign paroxysmal positional vertigo (AC-BPPV) can mimic down-beating positional nystagmus of central origin, particularly when it is bilateral. Factors that increase the probability of bilateral AC-BPPV include a history of bilateral multicanal BPPV, transient down-beating and torsiona...
متن کاملCentral Positional Nystagmus: A Systematic Literature Review
OBJECTIVE To provide a systematic review of the clinical and radiological features of lesion-induced central positional nystagmus (CPN) and identify salient characteristics that differentiate central from peripheral positional nystagmus (PN). METHODS Systematic literature search according to the preferred reporting items for systematic reviews and meta-analysis. RESULTS A total of 82 patien...
