Abstract

Objective: To study the demographics, vertigo profiles, and outcomes of adult patients with benign recurrent vertigo (BRV).

Patients and methods: This prospective study included patients with BRV who were admitted to a tertiary neurology clinic between June 2013 and June 2017. All patients underwent detailed clinical interviews and related examinations. A follow-up was then conducted through an outpatient or telephone interview.

Results: A total of 66 patients (48 females) were enrolled, and the mean age at the onset of vertigo was 35.2 years. Spontaneous vertigo was the most common type (77.8%), followed by positional vertigo (16.7%). The duration of vertigo attacks varied from minutes to 72 hours. A family history of migraine and/or recurrent vertigo was reported in 51.5% of patients. The overall response rate was 80.3%(53/66)after a median follow-up time of 32.5 months (range: 18-60 months). Forty (75.5%, of 53) patients still reported having vertigo attacks at the follow-up. The frequency of vertigo attacks was reduced in 32 (60.4%) patients and was unchanged in 8 (15.1%). Four (7.5%) cases developed into vestibular migraine, but none developed into Meniere's disease.

Conclusion: The outcomes of patients with BRV were benign, and the frequency of vertigo is significantly reduced. Few cases developed into vestibular migraine.

Keywords: benign recurrent vertigo; clinical features; follow-up study.
