In elderly and senile patients, dizziness is one of the most common symptoms: its prevalence in persons older than 65 years reaches 30%. Dizziness has a negative impact on the quality of life of the elderly, increases the risk of falling. There is no clear and unified concept of "dizziness". The term "dizziness" is a generic term used by patients to subjectively describe complaints and symptoms associated with a variety of changes in sensation, sense of movement, perception, or consciousness. Specialists often classify dizziness into systemic (true, vertigo) and non-systemic. Dizziness in the elderly is a geriatric syndrome, i.e. it can be caused by several simultaneously acting factors associated with the disruption of the functioning of many organs and systems, so in people of older age groups, the search for the cause of dizziness is difficult. 40% of elderly patients, presenting complaints of dizziness, doctors can not accurately determine the cause of the symptoms, as dizziness may initially have polietiologichesky origin. The causes of dizziness/vertigo include certain drugs, the application of which develops such an undesirable side reaction as dizziness. In this case, the term drug-induced dizziness/vertigo is used. The classes of drugs that most often lead to dizziness/vertigo include anticonvulsants, anesthetics, antihypertensive drugs, antidepressants, analgesics, hypoglycemic drugs, contraceptives, anti-inflammatory drugs, drugs for the treatment of diseases of the cardiovascular system, sedatives, tranquilizers and cytotoxics. When assessing the cause of dizziness/vertigo in persons of older age groups, it is necessary to take into account its possible causal relationship with the intake of any drug. In this case, it is necessary to reduce the dose of this drug or its complete abolition (replacement with another drug that does not cause this adverse effect). Modern diagnosis and treatment of dizziness in elderly and senile patients is impossible without the involvement of doctors of different specialties due to the polyetiology of this geriatric syndrome, with the obligatory assessment/revision of the sheet of medicinal prescriptions.
