Abstract
The acute vestibular syndrome (AVS) is a label for presentations of new-onset severe
dizziness, vertigo, or imbalance, with examination findings of nystagmus or gait unsteadiness.
The prototypical AVS presentation is the acute unilateral vestibulopathy due to vestibular
neuritis. Stroke is also a serious concern in patients with AVS. Most other peripheral
vestibular disorders present as episodic or chronic syndromes. In this article, the
diagnostic considerations, exam findings, and management of AVS are reviewed.
