Persistent Postural-Perceptual Dizziness, or "PPPD", is one of the newest vestibular conditions to receive its official diagnostic criteria. Thought to originate from within the vestibular system and brain, PPPD typically generates chronic dizziness, vertigo, and/or unsteadiness that is worsened when patients are in an upright position. Despite these symptoms, vestibular tests are often found to be normal which ends up leaving patients with no real answers as to the cause of their ongoing dizziness. PPPD - A Patient's Guide to Understanding Persistent Perceptual-Postural Dizziness was written for the PPPD patient in order to summarize the available research specific to what PPPD is, who it affects, and how it can be treated. In addition, chapters are included that describe the structure and function of the vestibular system along with summarizing several other related vestibular conditions that are capable of producing symptoms similar to what is experienced with PPPD. This book is designed to be a comprehensive source of information for PPPD patients that can educate and empower them in their battle against PPPD. Over 110 research papers are cited throughout the book, helping patients to be armed with the latest and most relevant information that will allow them to have informed and productive discussions with their medical provider.
