A simplified approach to dizziness/vertigo with tips from international expert, Dr. David Newman-Toker, Professor of Neurology, Ophthalmology and Otolaryngology at Johns Hopkins University. We learn how to differentiate stroke from other causes of dizziness/vertigo; how to approach the differential diagnosis in dizziness/vertigo; how to perform the Dix-Hallpike test, Epley maneuver, and HINTS exam; plus, who benefits from medical therapy and vestibular rehab.
Special thanks to Dr. Cyrus Askin who found our expert, wrote the questions for this episode, and acted as our cohost.
