SOPHISTICATION OF IDEAS ABOUT CHRONIC INSUFFICIENCY OF CEREBRAL CIRCULATION FROM THE POSITION OF AWARENESS OF THE PHENOMENON OF" RESISTANCE" OF THE BRAIN
The core of the clinical picture of chronic cerebrovascular insufficiency (CNMC) is a combination of 3 clinical syndromes: cognitive decline, balance disorders, and affective disorders, with varying degrees of severity observed in specific individuals. Identification of organic changes in the brain of patients with CNMC has become one of the most important achievements of the magnetic resonance imaging (MRI) technique after its introduction into wide clinical practice. For example, age-related memory loss for current events was associated with hippocampal atrophy, while Executive function disorders were associated with a phenomenon called "small vessel disease" (BMS). However, it should be noted that often in clinical practice there is a striking discrepancy between the degree of brain atrophy or the severity of BMS manifestations in individual patients with a similar pattern of cognitive disorders. Or, even more surprisingly, the absence of any significant clinical manifestations in patients with pronounced changes in the brain according to MRI data.
