In this paper, we introduce the activities of the vertigo/dizziness center at Nara Medical University. During a 24-month period between May 2014 and April 2016, we saw 837 cases complaining of vertigo/dizziness (males: 370; females: 467). The ratios of patients with central vertigo were 1.2%. After triaging the diagnoses, we decided to focus on benign paroxysmal positional vertigo (BPPV), which accounted for 43.5% of the patients overall and 66.2% of the female patients over the age of 60 years. The ratios of vertigo/dizziness patients with unknown origins were 10.2% overall, 15.5% in the female patients over the age of 60 years. We could reduce the ratios of vertigo/dizziness patients with unknown origins less than 1.0% through the system of one-week-hospitalization for vertigo/dizziness examinations. During the 22-month period between July 2014 and April 2016, we hospitalized 106 cases with vertigo/dizziness. The highest abnormal ratios were seen as 36.4% in subjective visual vertical (SVV) tests among all vertigo/dizziness examinations except for endolymphatic hydrops tests. SVV deterioration was seen not only in patients with Meniere's disease, but also in those with BPPV.
