前庭性片頭痛・メニエール病重複症候群 (Vestibular migraine/Meniere's disease overlapping syndrome) 例

抄録

　Migraine and dizziness/vertigo are closely related. Recently, the diagnostic criteria for vestibular migraine have been reported. Patients with Meniere's disease often complain of migraine. Moreover, some patients complain of migraine and recurrent vertigo attacks with hearing symptoms, which are clinical characteristics of Meniere's disease. In these cases, distinguishing between Meniere's disease and vestibular migraine can be difficult. Thus, these patients can be reasonably assumed to have vestibular migraine/Meniere's disease Overlapping Syndrome (VMOS). In this report, we present the case of a 28-year-old woman with VMOS. The patient had been complaining of migraine, right-side hearing loss, and recurrent vertigo attacks since the age of 15 years. She reported having two different types of vertigo: intense vertigo lasting for several hours, and continuous dizziness lasting for several days. She was referred to our hospital to control her vertigo. Based on her symptoms, the patient was diagnosed as having VMOS. Subsequently, conventional prophylactic pharmacotherapy for migraine was prescribed, and vestibular rehabilitation was introduced. As a result of this treatment, her symptoms gradually improved. The presence or absence of hearing loss and the duration of vertigo attacks are key symptoms for the discrimination between vestibular migraine and Meniere's disease.
