BPPV is the most common cause of peripheral vestibular dysfunction and is typically identified and treated with positioning maneuvers. The pathophysiology of BPPV will be reviewed in detail, as will demographic features, predisposing factors, and estimated prevalence of BPPV. This course will include a thorough discussion of canalithiasis and cupulolithiasis, including specific clinical implications. Nystagmus characteristics of BPPV variants will be discussed, and subjective and secondary BPPV will be reviewed. Additionally, differentiating features of alternative (non-BPPV) causes of positional vertigo will be discussed. Video-based cases and decision-making algorithms will be shared to reinforce content. This course will also include a question-and-answer session with Michael Teixido, MD. The course is appropriate for audiologists and occupational/physical therapists and assistants.

Chapters & learning objectives

Demographic Features, Predisposing Factors, and Pathophysiology

1. Demographic Features, Predisposing Factors, and Pathophysiology

Instruction will review demographic features, predisposing factors, and estimated prevalence of BPPV. The mechanics and clinical implications of canalithiasis and cupulolithiasis will be discussed, which is helpful to properly identify and treat BPPV.

BPPV Subtypes

2. BPPV Subtypes

Nystagmus characteristics of the mechanics of common BPPV variants will be discussed, which is helpful with differential diagnosis. Subjective and secondary BPPV will also be reviewed. Video cases will be utilized to emphasize learning objectives.

Alternative Causes of Positional-Type Dizziness

3. Alternative Causes of Positional-Type Dizziness

Differentiating features of alternative (non-BPPV) causes of positional vertigo will be discussed. Recognition of non-BPPV-related dizziness is critical for appropriate patient management. This chapter will include a question-and-answer session regarding BPPV-related controversies with Michael Teixido, MD.
