<b>Introduction:</b> Migrainous vertigo (MV) is one of the most common causes of episodic vertigo. Diagnostic criteria for MV are described in the appendix to the third edition of the International Classification of Headache Disorders (Beta Version). The dysfunction exerts its impact on certain peripheral and central structures within the vestibular system. </br></br> <b>Aim:</b> The aim of the study was to assess the function of the central and peripheral vestibular system in patients with MV based on the results of objective clinical tests including videonystagmography (VNG) and cervical vestibular evoked myogenic potentials (cVEMP) depending on the duration of the disease. </br></br> <b>Material and methods:</b> A query of the medical records of patients receiving vertigo treatment at the Department of Otolaryngo-logy of the Centre of Postgraduate Medical Education over the last four years returned a total of 84 cases of patients diagnosed with MV; the patients were assigned to either of the following two groups: study group I (SG1) – 42 patients with MV in whom the symp-tom onset had occurred within one year prior to hospital admission, and study group II (SG2) – 42 patients who had been suffering from vertigo for about 10 years. </br></br> <b>Results:</b> Patients in both groups (SG1 and SG2) were diagnosed with all three types of vestibular dysfunction (central, peri-pheral and mixed), with peripheral vestibular dysfunction being the predominant finding. A thorough analysis of the dura-tion of vestibular attacks revealed that the patients suffering from MV for a longer period of time (SG2) suffered from vertigo attacks which were longer than those in the patients with the shorter lasting-disorder (SG1). The duration of vertigo episodes was also estimated to be prolonged in peripheral and mixed types of vestibular disorders. The percentage of individuals with peripheral and mixed vestibular disorders increased significantly with increasing MV episode durations.
