Abstract
PDF - Background and Objectives: Migrainous vertigo (MV) is one of the recurrent vestibular syndromes and may present episodic vestibular and concurrent migraine symptoms. The clinical manifestations and neuro-otological findings of MV have been delineated over the last couple of decades, however, there are still lots of uncertainties. Materials and Methods: We performed a comprehensive literature search regarding the clinical manifestations and neuro-otological findings of MV compatible with the diagnostic criteria proposed by Neuhuaser. We found the published articles that addressed the clinical and neuro-otological findings and we performed a pooled analysis. Results: Even though the duration of MV attack was variable from seconds to days, the most common durations investigated in this study was minutes (range, 5-60 minutes). During MV attack, most patients had a migraine headache, but instead the other migraine symptoms (i.e., photophobia, phonophobia) could be found. There were positional nystagmus which may not meet a stimulated canal plane and spontaneous nystagmus and, less commonly, gaze-evoked nystagmus. Regarding bithermal caloric test, unilateral canal paresis could be found in 15-20% of MV patients as well as hyperexcitability in some patients. Oculomotor tests might show impaired pursuits (mainly saccadic pursuit) and saccadic abnormalities such as delayed latency and hypometric saccade. Conclusion: From the result of the pooled analysis, we have found several clinical and neuro-otological findings. However, vital neuro-otological findings which can provide a clue for the diagnosis of MV are still lacking. So the diagnosis of MV should depend on the clinical manifestations and a process of differential diagnosis.

Abstract

- 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.
