A timing-first framework makes dizziness less mysterious
REBOOT #505 Demystifying Dizziness with Dr. David Hale
Dizziness can signal anything from treatable BPPV to posterior circulation stroke, making symptom timing and targeted examination clinically consequential.
- 1Classifying dizziness as acute, episodic, or chronic—and identifying triggers—narrows the diagnostic field before examination begins.
- 2Dix-Hallpike testing supports BPPV diagnosis, while HINTS-Plus applies only during acute continuous symptoms and can identify central warning signs.
- 3Vestibular rehabilitation anchors recovery for neuritis, PPPD, and related disorders, while prolonged vestibular suppressants can hinder adaptation.
Don't miss
Hale explains why continuous acute vertigo with central HINTS findings should be treated as stroke, despite the limitations of early MRI.
The brief
David Hale builds the episode around a simple diagnostic reset: define what “dizziness” means, then classify it by timing, triggers, associated symptoms, and vascular risk.
For brief, head-movement-triggered spinning, Dix-Hallpike and supine roll testing can distinguish BPPV from orthostatic symptoms and more concerning episodic causes.
The sharpest safety issue arrives with continuous vertigo, vomiting, and gait instability: HINTS-Plus can help localize stroke risk, but only during an acute attack and with appropriate expertise.
The discussion then follows recovery and persistence, from vestibular neuritis and early rehabilitation to PPPD and mal de débarquement syndrome’s distinct motion-exposure history.
The durable takeaway is to match the examination to the syndrome, avoid prolonged vestibular suppressants, and treat chronic dizziness as a real, manageable condition.
