Background and Objectives It is being increasing recognized that the morbidities of migraine and balance disorders are interrelated. In fact, migrainous vertigo (MV) is one of frequent causes of recurrent vertigo in patients presenting to specialized dizziness clinics. Nevertheless, not many studies have reported clinical manifestations and treatment. Therefore, the aim of study was designed to assess clinical features and treatment patterns by a nationwide multicenter study. Materials and Methods Patients between 9 and 74 years of age who visited 17 Korean tertiary referral centers and 1 clinic from February to March 2009 were investigated using two forms of questionnaires. Results Overall, 318 patients with MV were enrolled. MV was responsible for ~8.45% of visits to the specialized dizziness clinics. One hundred seventy-five of these patients had definite MV and were included in assessing the clinical features. Vertigo characteristics of patients with definite MV were various. Vertigo was regularly as-sociated with headache in 87% of the patients. The duration of vertigo ranged from seconds to days. For the treatment patterns, an acute and prophylactic therapies were carried in most clinics. There were no differences in either acute or prophylactic therapies between department of neurology and otorhinolaryngology. Conclusions The results of this study suggest that MV the clinical features of MV also varies in Korea. In addition, most clinics provide similar patterns of practice in treatment for MV. The syndrome of MV deserves further research activity as it is relatively common and clinically relevant.
