1/3 video — The Stroke Hiding as Vertigo

Video 1 of 3 — LR03 Acute Vertigo: Identifying Stroke Risk — GP Clinician Video Series.

In this video:
• Why posterior circulation stroke is misdiagnosed in 30–50% of initial encounters — and why isolated vertigo is the most dangerous presentation.
• Defining acute vestibular syndrome (AVS): continuous vertigo over 24 h with nystagmus, nausea, and gait unsteadiness.
• Why ABCD2 fails in acute vertigo: sensitivity ~61% — do not use it in isolation.
• Pre-test probability of stroke by setting — primary care under 5%, ED with risk factors 20–25%, age over 50 with risk factors 30–40%.
• Why history alone cannot distinguish peripheral from central AVS — and what replaces it.
