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 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...
متن کاملDatabase of benign positional paroxysmal nystagmus.
Classification of various manifestations of benign positional paroxysmal nystagmus, due to canalolithiasis or to cupulolithiasis, as a reaction to movements and to the site of detritus, is now possible due to the integration of theoretical knowledge (relationships between the semicircular canals and/or ampullae and the vestibulo-ocular pathways) with the forms of nystagmus induced when the head...
متن کاملX-linked adrenoleukodystrophy presenting with positional downbeat nystagmus.
A 20-year-old man presented with dizziness and gait disturbance for approximately 2 months. Neurologic examination revealed spontaneous downbeat nystagmus (DBN), limb ataxia, and abnormal tandem gait (video on the Neurology® Web site at Neurology.org). Video-oculography showed augmented DBN during position change (figure 1). MRI revealed diffuse atrophy and signal changes in the brainstem and c...
