Benign Recurrent Vertigo: The Course of Vertigo Attacks Compared to Patients With Menière's Disease and Vestibular Migraine.

Objective: To explore the course of vertigo attacks in patients with benign recurrent vertigo (BRV) as compared to patients with Menière's disease (MD) and vestibular migraine (VM).

Study Design: Prospective cohort study.

Setting: Tertiary referral center.

Patients: Adult patients who visited the Apeldoorn Dizziness Center between January 2015 and November 2016 and who were diagnosed with BRV, VM or MD. During 3 years participants were contacted every 6 months by telephone to complete a study-specific questionnaire.

Main Outcome Measures: Vertigo attack frequency, use of medication, and Hospital Anxiety and Depression Scale (HADS).

Results: The study population ( = 121) consisted of 44 patients with BRV, 34 with VM, and 43 with MD. For the total follow-up period no statistically significant differences between the three diagnosis groups were observed for being attack-free in the past 6 months: OR = 0.86 (95% CI 0.34-2.17; = 0.745) for VM and OR = 1.06 (95% CI 0.44-2.51; = 0.902) for MD, compared to BRV. Overall, 19 patients (43.2%) with BRV, 13 (38.2%) with VM, and 35 (81.0%) with MD used medication to prevent vertigo attacks at any point during their 3-year follow-up. Throughout the observation period patients with MD showed an average of 3.37 points (95% CI 0.68-6.07; = 0.014) higher HADS scores relative to patients with BRV.

Conclusion: The course of vertigo attacks was rather favorable in the three groups, as 67-70% of the patients were free of vertigo attacks after 3 years of follow-up. The course of disease in patients with BRV was not distinctive from patients with MD and VM. We assume that BRV is a mild or incomplete variant of VM and MD, rather than a separate disease entity with distinct pathognomonic features.
