Using an algorithmic approach to acutely dizzy patients, physicians can often confidently make a specific diagnosis that leads to correct treatment and should reduce the misdiagnosis of cerebrovascular events. Emergency clinicians should try to become familiar with an approach that exploits timing and triggers as well as some basic "rules" of nystagmus. The gait should always be tested in all patients who might be discharged. Computed tomographic scans are unreliable to exclude posterior circulation stroke presenting as dizziness, and early MRI (within the first 72 hours) also misses 10% to 20% of these cases.

To assess the efficacy of the various therapies used for the prevention of vestibular migraine (VM). ⋯ Various treatment modalities have been evaluated for preventative treatment of VM. Physician familiarity, patient comorbidities, and the side-effect profiles of various interventions likely influence the selection of intervention. Future randomized controlled trials with restrictive inclusion criteria and generalizable standardized outcome measures will allow for more robust meta-analyses and for more evidence-based treatment of vestibular migraines.

Posterior circulation ischemic vertigo (PCIV) is one of the most complaint symptoms in clinical, and is associated with high risk of recurrence. Current studies show that acupuncture has therapeutic effect on releasing symptom as well as improving the blood flow of posterior circulation. In this review, we aim to assess the efficacy and safety of acupuncture for PCIV. ⋯ Based on current clinical studies, this systematic review and meta-analysis will provide evidence-based basis for the efficacy and safety of acupuncture in treating PCIV.

Review Meta Analysis
Can emergency physicians accurately rule out a central cause of vertigo using the HINTS exam? A systematic review and meta-analysis.
Dizziness is a common complaint presented in the emergency department (ED). A subset of these patients will present with acute vestibular syndrome (AVS). AVS is a clinical syndrome defined by the presence of vertigo, nystagmus, head motion intolerance, ataxia, and nausea/vomiting. These symptoms are most often due to benign vestibular neuritis; however, they can be a sign of a dangerous central cause, i.e., vertebrobasilar stroke. The Head Impulse test, Nystagmus, Test of Skew (HINTS) examination has been proposed as a bedside test for frontline clinicians to rule out stroke in those presenting with AVS. Our objective was to assess the diagnostic accuracy of the HINTS examination to rule out a central cause of vertigo in an adult population presenting to the ED with AVS. Our aim was to assess the diagnostic accuracy when performed by emergency physicians versus neurologists. ⋯ The HINTS examination, when used in isolation by emergency physicians, has not been shown to be sufficiently accurate to rule out a stroke in those presenting with AVS.
