Davis Company PP New York, NY SN 9780803639706 LK fadavispt.mhmedical.com/content.aspx?aid=1135016300 RD 2024/03/28 AB Although benign paroxysmal positioning vertigo (BPPV) is a common finding that is relatively easy to diagnose and treat, there are causes of positional nystagmus and positional vertigo that are a result of either abnormalities within the central nervous system or other peripheral vestibular conditions. These conditions will not respond to the conservative measures described for the treatment of BPPV. The goal of this appendix is to help the clinician identify the signs and symptoms of positional nystagmus and positional vertigo that are not consistent with BPPV and are suggestive of other disorders.
