Prospective Registry of Vertigo Due to Vertebrobasilar Transient Attacks.

Vertigo and dizziness are common neurological complaints in the emergency department and may represent a wide spectrum of etiologies, including vertebrobasilar transient neurological attacks (VB-TNAs). Distinguishing VB-TNAs, particularly vertebrobasilar transient ischemic attacks (VB-TIAs), from migraine-like and other non-vascular conditions is often challenging at first presentation due to the absence of specific biomarkers and overlapping clinical features. The UTRAVERA study is a multicenter, prospective, observational investigation designed to characterize the clinical features of patients presenting with acute transient vertigo or dizziness suspected to be VB-TNAs. The study will also evaluate diagnostic evolution over time, treatment responses, and prognostic factors associated with clinical outcomes.
