BPPV Pathophysiology and Differential Diagnosis of Positional Vertigo

Course overview

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.
