Abstract

Acute unilateral vestibulopathy (AUV) is the recommended term [rather than the more widely used ‘vestibular neuritis (VN)’] for all pathologies involving sudden impairment of the unilateral peripheral vestibular function regardless of the exact location of the lesion. Acute vestibular syndrome (AVS) is an upper-level entity of AUV, which is the most common cause of AVS, and includes acute central vertigo. AVS typically presents with the symptoms of new onset continuous vertigo, gait instability, and nausea/vomiting lasting several days to weeks. The video head impulse test (vHIT) was recently developed and has been widely adopted at clinics and emergency centers. In this study, we will review the differential diagnosis of AVS using vHIT. In addition, we will describe the subtypes of VN and the use of vHIT for follow-up testing in AVS.
