We assume that the reversal of nystagmus in this case is due to second-phase endolymphatic flow due to reversal of clot movement. The mechanism of spontaneous inversion of nystagmus in a patient with left-sided PC-BPPV (dark arrow indicates the direction of the rotation). The upbeating spontaneous nystagmus and CPN have been associated with central disorders such as tumor, stroke, and multiple sclerosis affecting brachium conjunctivum or the ventral tegmental tract.4 Many of these patients also had findings of abnormal smooth pursuit.

In the head-hanging position, positional down-beating nystagmus (p-DBN) generally occurs in patients with a cerebellar nodulus lesion [].Several authors have recently reported that nystagmus of benign paroxysmal positional vertigo of the anterior semicircular canal (A-BPPV) is observed as a down-beating component with or without a torsional component in the head-hanging .

Therefore, we speculated that positional nystagmus in our patient was due to the light cupula of the posterior semicircular canal and diagnosed that the right ear was affected. Benign paroxysmal positional vertigo: mechanism and management. The condition of this light cupula, characterized by a lower specific gravity than the endolymph, reportedly explains direction-changing characteristics of the first phase of positional alcohol-induced nystagmus with changes in head positions [5, 6].

The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). During all the steps of the maneuver, the nystagmus remains the same, because the otoconia and the endolymphatic flow follows the same direction and therefore the same response (ampullofugal/excitatory in AC-BPPV or ampullopetal/inhibitory in APC-BPPV).

Typical posterior canal BPPV, the most frequent form of BPPV, is characterised by a paroxysmal nystagmus evoked through the Dix-Hallpike test; the nystagmus is torsional clockwise for the left side, counter-clockwise for the right side, with a vertical up-beating component. In patients with benign paroxysmal positional vertigo, BPPV; a torsional-vertical down beating positioning nystagmus can be elicited in the supine straight head-hanging position test or in the Dix-Hallpike test to either side.

Then, a burst of endolymphatic reflux in the opposite direction dragging the clot away from the cupula will result in clockwise upbeating nystagmus when maintaining the head rotation to the pathological left side. Posterior canal is most commonly affected, but anterior and horizontal canals can also be affected and are associated with slightly different clinical manifestations.

Besides, we do not prefer to use the term apogeotropic for patients with downbeating nystagmus which may lead to confusion in the nomenclature since apogeotropic nystagmus of the lateral canal describes the otoliths located close to the cupula and apogeotropic nystagmus of the posterior canal describes the otoliths located away from the cupula.

Diagnosis of posterior canal benign paroxysmal positional vertigo (PC-BPPV) is based on a transient upbeating clockwise or counterclockwise rotational nystagmus in the presence of latency, adaptation, and habilitation associated with a brief and intense sense of vertigo during head-hanging maneuver. Reversal of initial positioning nystagmus in benign paroxysmal positional vertigo during maintaining the head position is quite unusual and an interesting finding.

Results: This seems most likely to be due to retinal disease. The goal of this appendix is to help the clinician identify the signs and symptoms of positional nystagmus and positional vertigo that are not consistent with BPPV and are suggestive of other disorders.
