Comparison between objective and subjective BPPV

1 March 2017 | | Benign paroxysmal positional vertigo, canalolithiasis, nystagmus, repositioning manoeuvre

BPPV presentation in ENT clinics is variable. The objective of this study was to examine differences in demographic and clinical features, as well as treatment outcomes, between classic objective BPPV (O-BPPV) and subjective BPPV (S-BPPV). Unlike classic BPPV (with nystagmus),...

Type 2 diabetes and BPPV

Previous research has shown an association between BPPV and certain medical conditions such as hypertension, hyperlipidaemia and type 1 diabetes. The authors in this retrospective observational study investigated the interaction between BPPV and type 2 diabetes by examining the ‘role...

International classification of BPPV

1 May 2016 | | Vertigo, criteria, diagnosis, nystagmus, positional

In the past few years, the Bárány Society has made great strides in defining and classifying vestibular disorders along the lines of the international classification of diseases. This article addresses the diagnostic criteria for BPPV, the commonest cause of vertigo....

Horizontal nystagmus: vestibular neuritis or lateral canal BPPV?

1 January 2016 | | BPPV, Vestibular neuritis, positional nystagmus, pseudo-spontaneous nystagmus, spontaneous nystagmus

A horizontal nystagmus due to lateral canal (LSC) BPPV that is present in the upright position, that changes direction with head turn in the horizontal plane has been termed ‘pseudo-spontaneous nystagmus’ (PSN) because it mimics that of vestibular neuritis. The...
