About this Research Topic
In 1921 Robert Bàràny first described the clinical picture of a patient suffering from benign paroxysmal positional vertigo (BPPV). 30 years later, Dix and Hallpike detailed the characteristics of BBPV and developed the diagnostic maneuver for posterior canal benign paroxysmal positional vertigo.
BPPV is a common peripheral vestibular disorder caused by displaced otoconia into the semicircular canals. This leads to the mechanical stimulation of the vestibular receptors and presents as positional vertigo and positional nystagmus related to changes in head placement. BPPV has a significant social impact, especially for elderly patients who report an impaired quality of life and have an increased risk of falls. Furthermore, despite having learned much about its pathogenesis in the past decades, many of the features of BPPV remain mysterious. In the clinic, doctors should especially be wary of when the clinical features of BPPV are mimicked by more serious disorders such as tumors and stroke. However, despite the physiopathology of the BPPV remaining mainly speculative, its diagnosis and treatment are often efficient and effective.
The main aim of this Research Topic on BPPV is to provide readers with the most up-to date information regarding the current diagnostic and treatment options for patients with BPPV. The Research Topic will also emphasize what we do not know in terms of epidemiology, etiology and mechanisms of physiopathology that may led to a better understanding this disorder. New theoretical models will also be presented.
For this Research Topic we welcome articles covering all aspects of benign paroxysmal positional vertigo, including: epidemiology, etiology, physiopathology, clinical presentation, differential diagnosis with central positional nystagmus, and therapeutic options.
