Vertigo is a common clinical symptom and is closely related to many diseases, and because of this, misdiagnosis and underdiagnosis often occur. The reason for this is that most of them are due to the misunderstanding of patients, and it is difficult to associate vertigo with ear diseases. In fact, the balance organ of human body is located in the inner ear, and 60-70% of vertigo is caused by diseases of the vestibular system of the inner ear. Clinically, the diseases that cause vertigo mainly include the following two major disciplines. Otolaryngological diseases: otoliths, Meniere’s disease, vestibular neuritis, sudden deafness with vertigo, delayed membranous vagal effusion, vaginitis, Tullio’s syndrome, Dandy’s syndrome, LVAS syndrome, Hunt’s syndrome, vestibular paroxysms, etc. Neurological diseases: cerebrovascular disease, vestibular migraine, demyelinating lesions, epileptic vertigo, psychogenic vertigo, brain tumors, etc. In addition, certain somatic diseases can also trigger vertigo, such as hypertension, upright hypotension, hypoglycemia, anemia, etc. Therefore, patients with vertigo should first choose a vertigo specialist clinic or vertigo treatment center for consultation. If there is no such specialized institution, the first consultation can be made in otorhinolaryngology or neurology.
