Unlock the mysteries behind dizziness, vertigo, and lightheadedness with renowned experts Dr. Douglas Beck and Dr. Joseph Sakumura. Join us as we explore how the different sensations of movement can reveal underlying vestibular disorders. Dr. Sakumura details the critical role of nystagmus in differential diagnosis, guiding us through the nuanced process of identifying whether a vestibular disorder is peripheral or central, and how the direction of nystagmus can indicate the affected ear.
Discover the nuanced differences between vestibular neuritis and Meniere's disease. We'll unpack how herpes simplex virus contributes to vestibular neuritis, leading to sudden and severe vertigo, in contrast to the recurring episodes of Meniere's disease. Our conversation also tackles the challenge of distinguishing these conditions from migraines, which often manifest with similar symptoms. Expect to gain a comprehensive understanding of the diagnostic hurdles faced by healthcare professionals in this complex area of vestibular health.
Our final focus is on Meniere's disease and endolymphatic hydrops, exploring their shared symptoms and the diagnostic criteria from the Barany Society. Dr. Sakumura shares insights into the use of electrococleography (ECOG) for evaluating endolymphatic hydrops and discusses the intricate surgical approaches for Meniere's disease treatment. We also dive into the cautious prescription of vestibular medications like Meclizine, stressing the necessity for accurate diagnosis before treatment to ensure effective patient care. Tune in for an enlightening discussion that promises to deepen your understanding of these critical topics in vestibular health.
