Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of dizziness in adults. BPPV is caused by displacement of otoconia from the utricle into the semi-circular canals, resulting in short-duration positional dizziness, which can have a significant impact on individuals’ activities of daily living and quality of life. While in the majority of BPPV cases, otoconia are displaced into the posterior canal, otoconial debris can migrate into the horizontal canal, anterior canal, and short arm of the canal.  Additionally, BPPV can be objective or subjective or can suggest vestibular agnosia. The purpose of this course is to review atypical BPPV presentations including anterior canal BPPV, horizontal canal BPPV, short-arm BPPV, subjective BPPV or vestibular agnosia. Appropriate treatment strategies will also be reviewed.

Learning Objectives:

• Identify the presence of BPPV and the canal involved.
• List treatment options for anterior and horizontal canal BPPV
• List patient symptoms associated with subjective BPPV and vestibular agnosia.
