Benign paroxysmal positional vertigo

Auris Nasus Larynx, 2022
Benign paroxysmal positional vertigo (BPPV) is characterized by positional vertigo (brief attacks of rotatory vertigo triggered by head position changes in the direction of gravity) and is the most common peripheral cause of vertigo. There are two types of BPPV pathophysiology: canalolithiasis and cupulolithiasis.

Benign Paroxysmal Positional Vertigo

The Laryngoscope, 1997
AbstractBenign paroxysmal positional vertigo (BPPV) has received renewed clinical interest. At the Johns Hopkins Otological Vestibular Laboratory, 781 patients were tested on more than one occasion between September 1976 and November 1992. Of these patients, 187 (24%) were found to have positional nystagmus consistent with a diagnosis of BPPV.

Benign Paroxysmal Positional Vertigo

Journal of Neuroscience Nursing, 1994
Benign paroxysmal positional vertigo (BPPV) is a peripheral vestibular disorder affecting the posterior semicircular canal. It is most often idiopathic in nature, though it has been known to occur in patients following head injury, Meniere's disease, acoustic neuroma and viral neuronitis.

Benign Paroxysmal Positional Vertigo

Seminars in Neurology, 2013
Benign paroxysmal positional vertigo (BPPV) is the most common and the most effectively treated vestibular disorder. The prevailing pathomechanism is canalolithiasis, which is otoconia falling in one of the semicircular canals where they move in response to changes of the head position, triggering excitation of the vestibular receptors of the affected ...

Benign Paroxysmal Positional Vertigo

2005
Purpose of Chapter: This chapter discusses the recent progress made in understanding the pathophysiology, diagnosis, and treatment of benign paroxysmal positional vertigo (BPPV). Recent Findings: Recent evidence supports the canalolithiasis model as the pathophysiological mechanism and predominant subtype of BPPV.

Benign Paroxysmal Positional Vertigo

New England Journal of Medicine, 1999
Benign paroxysmal positional vertigo is a common disorder of the inner ear that should be suspected in all patients with a history of positionally provoked vertigo. The condition appears to be caused by free-floating debris in the posterior semicircular canal.

Benigner paroxysmaler Lagerungsschwindel

Der Nervenarzt, 2001
Benign paroxysmal positional vertigo is the most common vestibular disorder, accounting for about 20% of referrals in specialized dizziness clinics. Nowadays, canalolithiasis of the posterior semicircular canal has been widely accepted as the biological basis for typical benign paroxysmal positional vertigo as it is compatible with all clinical ...

Benign paroxysmal positional vertigo

Current Neurology and Neuroscience Reports, 2001
Benign paroxysmal positional vertigo (BPPV) is the most common and most treatable cause of vertigo. In most cases, a simple maneuver that takes less than a few minutes to do resolves the problem. BPPV is caused by misplaced calcium carbonate crystals (otoconia) in the semicircular canal of the inner ear that have broken free from the utricle.
