Dizziness Symptom Type Prevalence and Overlap: A US Nationally Representative Survey

Substantial overlap of dizziness types exists among US adults with dizziness. People otherwise having features of traditionally vertigo-based disorders also typically report multiple dizziness types and do not typically report vertigo as the primary type. Symptom types correlate more strongly with each other than with other clinical or demographic variables. These findings suggest that the traditional emphasis on dizziness types is likely of limited clinical utility.
