Management of Acute Vertigo with Head Movement Provocation

Diagnosis and Clinical Presentation

The American Academy of Otolaryngology-Head and Neck Surgery recommends considering benign paroxysmal positional vertigo (BPPV) in patients with dizziness recreated with turning of the head, short-duration vertigo episodes, no hearing loss, tinnitus, or aural fullness, and a normal neurologic examination 2, 3
Patients with BPPV typically experience short-duration vertigo episodes, described as intense spinning, and no hearing loss, tinnitus, or aural fullness 2, 3
A normal neurologic examination rules out central causes like stroke, and the absence of hearing loss, tinnitus, or aural fullness distinguishes BPPV from Ménière's disease 2, 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends the Epley maneuver (canalith repositioning procedure) as first-line therapy for BPPV, achieving 80% vertigo resolution with only 1-3 treatments, compared to 30.8% improvement with medication alone 1, 4
The Epley maneuver should be performed immediately, as it has high success rates and can resolve symptoms quickly 1, 4

The American Academy of Otolaryngology-Head and Neck Surgery explicitly recommends against routine treatment of BPPV with meclizine or other vestibular suppressants, as there is no evidence that they are effective as definitive treatment for BPPV, and they can interfere with central compensation and prolong recovery 1, 4, 5
Meclizine causes drowsiness and cognitive deficits, and its use can delay definitive therapy and prolong symptoms 1, 4

Patients with BPPV should be reassessed within 1 month to document symptom resolution or persistence, and counseled that BPPV recurrence rates are 10-18% at 1 year and may reach 36% over time 1, 4, 5
If symptoms recur, the Epley maneuver can be repeated with similar success rates, and if symptoms persist despite 2-3 repositioning attempts, consider vestibular rehabilitation therapy 4
