Dizziness accounts for 4-5% of all emergency department (ED) chief complaints and 26% of ED patients endorse dizziness in their review of systems.  Although most presentations for dizziness are benign, nearly 200,000 strokes present with dizziness each year in the United States (Edlow et al. 2008).   Misdiagnosis of vertebrobasilar strokes is common, as symptoms may be minimal and patients often change how they characterize their symptoms.  In the video below, Dr. Siket covers a systematic and evidence based approach to guide your workup of this all too common patient.
