Abstract W P293: Opportunities For Interventions In Stroke-Dizziness Presentations: A Prospective Single Center Surveillance Study
2015
Objective: Ischemic stroke can be a diagnostic dilemma in presentations of acute dizziness and increased resources will likely be required to reduce instances of misdiagnosis. To inform the potential value of the deployment of increased resources, we sought to describe opportunities for therapeutic interventions from a series of acute dizziness-stroke patients who had diagnostic uncertainty (i.e., only mild or no general neurologic deficits) on presentation. Methods: Active and passive surveillance methods were used at a tertiary care center to identify acute dizziness patients with nystagmus or imbalance, excluding those with benign paroxysmal positional vertigo, medical causes, or moderate-to-severe neurologic deficits. Stroke was defined as any acute infarction on a clinical or research MRI performed within 14 days of dizziness onset. Results: From November 21, 2009, to March 29, 2013, we identified 26 patients with acute ischemic stroke presenting with dizziness and either mild or no general neurologi...
