The benefits of early specialist input are early identification of central positional nystagmus, a decrease in symptom duration, reduced number of therapeutic maneuvers required for symptom resolution, and lower rates of iatrogenic multi-canal BPPV.

Comparative Study of Clinical Features of Patients with Different Types of Benign Paroxysmal Positional Vertigo

A diagnostic pattern useful in patients admitted due to vertigo is established, based on the most common clinical characteristics of patients suffered from posterior canal BPPV, horizontal canal BPPV with geotropic (HCG-BPPV) and apogeotropic nystagmus (HCA-BPPV).

Epley’s Influence on Horizontal Canal BPPV Variants

Dr. Epley has been instrumental in defining the mechanisms and treatment of BPPV variants, including those of the horizontal canals, and was the first to propose mechanistic theories which better match the most recent evidence.

Diagnostic Errors in the Acutely Dizzy Patient—Lessons Learned

Diagnostic errors identified in the evaluation and treatment of the acutely dizzy patient are reviewed and moderate training of non-experts allows for significant improvement in diagnostic accuracy in the acutely dizzy patient and thus should be prioritized.

Acute positional vertigo in the emergency department—peripheral vs. central positional nystagmus

Positional vertigo should be assessed with positional maneuvers such as Dix-Hallpike and Roll tests in the ED to identify peripheral and central nystagmus features.

Episodic Vertigo: A Narrative Review Based on a Single-Center Clinical Experience

A precise and in-depth research of the patient’s clinical history is the key to suspect or make a diagnosis together with the search for some instrumental or clinical hallmark, especially in cases where the clinical picture does not fully meet the international diagnostic criteria.

Transient Response to Liberation Maneuvers in Central Positional Nystagmus Due to Cerebral Metastases Mimicking Benign Paroxysmal Positional Vertigo– A Case Report

A patient with isolated positional vertigo and central PN which mimicked a lateral-canal cupulithiasis with short-lasting responses to liberation maneuvers may also be seen in CPN, mimicking the response-pattern expected in BPPV cases.

Usefulness of Nystagmus Patterns in Distinguishing Peripheral From Central Acute Vestibular Syndromes at the Bedside: A Critical Review

The usefulness of nystagmus patterns in discriminating peripheral and central causes strongly depends on the pattern seen and the type of testing performed, being highly predictive of a central cause for torsional and vertical spontaneous nystagmus, downbeat, or apogeotropic horizontal and treatment-refractory positional nystagmus.

Clinical Practice Update Part II: Considerations for Treatment and Management of Benign Paroxysmal Positional Vertigo

This manuscript is to simplify education that is related to BPPV, outside of diagnosis and treatment maneuvers, and increase awareness to supplemental information related to BPPV for all healthcare providers.

Benign Paroxysmal Positional Vertigo: Comparison of Idiopathic BPPV and BPPV Secondary to Vestibular Neuritis

The findings of the study showed that the patients with secondary BPPV due to VN are much younger, have symptoms of only posterior semicircular canal involvement, and require more treatments compared to patients with idiopathic B PPV.

The Canalith Repositioning Procedure: For Treatment of Benign Paroxysmal Positional Vertigo

The results of the Canalith Repositioning Procedure support an alternative theory that the densities that impart gravity-sensitivity to a semicircular canal in BPPV are free in the canal, rather than attached to the cupula.

Localizing signs in positional vertigo due to lateral canal cupulolithiasis

From the behavior of lateral nystagmus in different head positions, the lateral canal system of the inner ear is shown to be gravity-sensitive and the side on which the cupula is affected can be determined.

Apogeotropic Horizontal Canal Benign Paroxysmal Positional Vertigo: Zuma e Maia Maneuver versus Appiani Variant of Gufoni

For HSC cupulolithiasis, ZeM is more effective than App in those cases in which there is a history of previous episodes of BPPV, and the presence of symptoms and/or nystagmus at the first follow up was studied.

Management of Lateral Semicircular Canal Benign Paroxysmal Positional Vertigo

Using a single maneuver and its modification may facilitate daily neurotological practice in patients with peripheral vestibular vertigo using both apogeotropic and geotropic variants of lateral canal BPPV.

Another maneuver has been developed and is described, similar to the Semont maneuver, moving the patient from a seated position to a position on the right or left side, depending the pathology and type of vertigo (geotropic/apogeotropic).

Central Positional Nystagmus: A Systematic Literature Review

There is a lack of robust data on the clinical and radiological characteristics of CPN highlighting the need for better phenotyping of CPM to help differentiate this entity from peripheral causes of PN.
