This article presents operational diagnostic criteria for benign paroxysmal positional vertigo (BPPV), formulated by the Committee for Classification of Vestibular Disorders of the Barany Society. The classification reflects current knowledge of clinical aspects and pathomechanisms of BPPV and includes both established and emerging syndromes of BPPV. It is anticipated that growing understanding of the disease will lead to further development of this classification.

Benign paroxysmal positional vertigo: Diagnostic criteria

Manuscript History: Benign paroxysmal positional vertigo is the most common cause of recurrent vertigo which last for a few seconds usually managed head positioning maneuvers. The most common form of BPPV occurs when otoliths from the macula of the utricle fall into the lumen of the posterior semicircular canal responding to the effect of gravity. BPPV appeared to be associated with previous trauma (6.7% of all patients), ipsilateral Meniere"s disease (6.5%/), ipsilateral vestibular neuritis(5.6%),history of BPPV affecting the same ear(5.2%),a severe systemic disease(4.6%) and history otologic surgery(1%). The effectiveness of the maneuvers depending on correct diagnosis of canal affected, cupula involved or not, single or multiple canal affected and sidedness of structures. The important question of whether repeated maneuvers during one session are more effective than just one remains to be examined systematically. confidence while walking 4 . Other charaterstic of BPPV include rotational vertigo(in 86%),oscilloscopia(31%),nausea(33%),vomiting(14%),imbalance(49%),fear of falling(36%), and falls(1%). 5 Benign paroxysmal positional vertigo can occur through the lifespan from childhood to elders 6 The prevalence of BPPV in this young adult population was a surprising 9% 7 . It can affect the quality of life of elderly patients and is associated with reduced activities of daily living, falls, and depression. Patients with BPPV experience delays in diagnosis and treatment, the mean delay being 92 weeks, and they frequently are inappropriately treated with vestibular suppressant medications 7 . BPPV is more prevalent in women (2 times more) as compared to men. Patients with BPPV are 5 times more likely to have relations with BPPV compared to other dizzy patients suggesting a familial tendency. 5 BPPV is found in isolation and termed primary or idiopathic BPPV in approximately 50% to 70% of all cases. The most common cause of ""secondary"" BPPV is head trauma, representing 7% to 17% of all cases. Other causes of
