Vestibular vertigo is most often caused by benign paroxysmal positional vertigo (BPPV), Meniere’s disease, vestibular neuritis, vestibular migraine or stroke. Features, diagnosis and treatment of vestibular vertigo in patients with these diseases are discussed. The authors analyze common diagnostic errors based on the data of 700 outpatients (205 men and 495 women, aged 25—88 years, mean age 55 years). It is noted that the cause of vertigo is often misdiagnosed with vertebral-basilar insufficiency, discirculatory encephalopathy, cervical spine pathology; at the same time, BPPV, Meniere’s disease, vestibular neuritis or vestibular migraine is diagnosed less often. This fact reflects the lack of awareness of physicians about these diseases. BPPV, Meniere’s disease and migraine are effectively treated and therefore their diagnosis and adequate treatment are of great importance.
