[Chronic cerebral ischemia and dizziness].

Older age is characterized by a high prevalence of dizziness/vertigo, including various variants - central and peripheral vestibular disorders, feelings of instability, balance disorders. High frequency of dizziness and chronic cerebral ischemia in the elderly age category supports traditional ideas about relationship of these pathologies. However, there is a known overestimation of Chronic cerebral ischemia as a cause dizziness of and unclear mechanisms of this process. With a high prevalence of vestibular disorders in the elderly and their verification, in some cases, the causes of dizziness cannot be identified. This has prompted the designation of this type of dizziness as «unexplained». The article cites recent studies demonstrating a relationship between «unexplained» dizziness and chronic cerebrovascular pathology. The theories explaining the mechanisms of this association are proposed. The role of choline alphoscerate in the treatment of dizziness in Chronic cerebral ischemia has been demonstrated. The mechanisms of positive effect of choline alphocerate and prospects of its using.
