Summary:
Vascular cognitive disorders (TFR) are one of the urgent problems of clinical neurology and the second most common cause of dementia. TFR cover a number of disorders in which vascular factors cause or contribute to a decrease in cognitive functions. Among the main risk factors for the development of the Investigative Committee, elderly age and vascular factors are considered, leading to endothelial dysfunction and damage, which in turn can cause neurovascular dysfunction, increased permeability of the hematoencephalic barrier and microsyuded thrombosis. One of the most important mechanisms for the development of the Investigative Committee is oxidative stress, which indicates the need to use agents with antioxidant activity. Such drugs include Mexidol (ethylmethylhydroxypyridine succinate). Mexidol has pronounced antioxidant and antihypoxic properties. The clinical effectiveness of Mexidol in relation to the Investigative Committee was established in many studies. Key words: chronic cerebrovascular failure, oxidant stress, vascular cognitive impairment, endothelial dysfunction, Mexidol.

Summary:
Purpose of the study. Assessment of the effectiveness and safety of prolonged sequential therapy with Mexidol and Mexidol Forte 250 for a functional outcome in patients with ischemic stroke (AI) in the basin of the internal carotid artery. Material and methods. The study includes 50 patients with the first AI in the carotid pool, which were hospitalized in the SOKB on the 1st day from the onset of the disease. Patients of the main group (n = 25) received Mexidol 500 mg intravenously dropped 1 time per day for 14 days, then Mexidol Forte 250 in tablets of 250 mg 3 times a day for 60 days. Patients of the comparison group (n = 25) received standard basic therapy. The reliability of intergroup differences was evaluated using the Mann-Uiite criterion, the exact criterion of Fisher, and the calculation of relative risk (OR). Statistically significant were the differences at the level of p <0.05. Results. After 14 days of therapy, both groups of patients demonstrated positive dynamics regarding the initial indicators. At the same time, patients who received Mexidol had a higher score on the MOS scale (U = 173.5, P = 0.006) showed a lower score when performing tasks for dynamic praxis (U = 214.0, P = 0.028) and optical Spatial disorders (U = 170.5, p = 0.003), the better strength of memorization (181.5, p = 0.006), and also better performed tasks for generalization (U = 200.5, p = 0.014). By the 74th day, the absence of moderate cognitive disorders (MOS> 26 points) was diagnosed in 17 (68%) patients of the main group and 14 (56%) patients of the comparison group. Differences without a statistically significant difference. At the same time, patients of the main group had a statistically lower score on the NIHSS scale (U = 124.0, p <0.001) and a lower degree of disability: the total score on the MRS 0-2 scale was reached in 19 (76%) patients of the main group and only In 12 (48%) patients of the comparison group (OR = 3.34, F = 0.07, P <0.05). Also, patients who received prolonged sequential therapy with Mexidol and Mexidol Forte 250 had more mild spatial disorders than patients of the comparison group. Conclusion. Conducting consistent therapy with Mexidol and Mexol Forte 250 in the acute and early recovery periods of AI positively affects the regression of focal neurological symptoms, increases the likelihood of independence in everyday life by 3.34 times, and helps to reduce the severity of optical, neurodynamic disorders and memory impairment. Key words: ischemic stroke, Mexidol, Mexidol Fort 250, cognitive impairment, functional outcome.

The main forms of cognitive disorders (KN) are characterized by significant variability of the connection of morphological changes and clinical manifestations. One of the promising concepts explaining these features is the modern model of the cognitive reserve. The concept of a cognitive reserve, most widely used in the context of dementia, is often used to explain the mechanisms of the stability of the functional systems of the brain to the development of neuropathological changes. The mechanisms that ensure the functioning of the cognitive reserve are normal and during the pathology of the brain are the activation of neuronal relationships of the brain. Therefore, persons with a higher efficiency of neuronal connections and the ability to form alternative neuronal networks and, accordingly, the formation of cognitive strategies in response to an increase in cognitive load are characterized by a higher level of cognitive reserve. The modern concept of a cognitive reserve opens the prospects for explaining the causes and mechanisms of the development of KN, and also justifies the possibilities of using alternative strategies for their correction.

Key words: cognitive reserve; brain reserve; Alzheimer's disease; Dementia.

Vascular depression is a very frequent and serious complication of cerebrovascular diseases. Vascular factors play an important role in the formation of affective disorders. Depression, in turn, also has a negative impact on the course of cardiovascular pathology, contributing to its progression, worsens the quality of life of patients, reduces functional activity, increases mortality, increases the risk of stroke. The diagnosis of vascular depression is confirmed by the detection of leulyoaaresis on an MRI, while the hyperinatheism of the deep parts of the white matter is important. Very important features of vascular depression are the presence of cognitive impairment and increasing the risk of dementia.

Summary:
one of the leading causes of mortality, disability and pronounced maladaptation of patients is an ischemic stroke, which accounts for about 80% of all types of acute cerebrovascular accident. At the same time, approximately 2/3 of patients detect residual phenomena of cerebrovascular circulation disorders of varying degrees of severity. Currently, the problem of ischemic stroke is given great attention, and one of the aspects of work in this area is the developed international and domestic recommendations for the prevention of stroke, treatment and rehabilitation of patients who have undergone stroke. The article provides an overview of the latest clinical recommendations for the early management of patients with acute ischemic stroke of the American Association on the Problems of the Heart and the American Association for the Treatment of Stroke, as well as the features of the therapy and prevention of stroke in Russia, European and the USA. Key words: ischemic stroke, clinical recommendations, therapy of ischemic stroke.

Summary:
Purpose of the study. To study in dynamics the rheological properties of blood in patients with acute ischemic stroke (AI) when Mexidol is included in complex therapy. Material and methods. 60 patients with acute AI examined. Mexidol (500 mg/day intravenously within 20 days) received 32 patients, 28 patients received magnesium sulfate (2000 mg/day intravenously for 20 days). The control group included 20 patients without a history of cardiovascular pathology. Assessment of rheological indicators of blood (whole blood viscosity, plasma viscosity, hematocrit, aggregation and deformability of red blood cells, the level of fibrinogen in plasma) was carried out in patients three times: during the first 12 hours, on the 3-5th day and on the 18-20th day and on the 18th-20th day After hospitalization. Results. All patients with a stroke observed a high viscosity syndrome. A statistically significant decrease in blood viscosity was detected in patients receiving Mexidol, by the 3-5th day of the disease at low shift speeds and by the 18-20 days at the speed of the shift from 3-100 S1. By the 18-20th day of the disease, reliable differences in the value of hematocrit (p = 0.026) and the content of fibrinogen (p = 0.017) were revealed in groups of patients receiving various therapy. A reliable increase in the erythrocyte deformability index in patients who received the therapy with Mexidol by the 3-5th day at the shift speeds of 90 and 890 S-1, by the 18-20th day at the shift speeds 90–360 S-1, was recorded. Conclusion. The study shows the effect of Mexol's drug on blood fluidity in the dynamics of acute cerebral ischemia and its effectiveness is proved in reducing blood viscosity by reducing the level of hematocrit and fibrinogen, as well as an improvement in the deformation ability of red blood cells. Keywords: acute ischemic stroke, rheological indicators of blood, blood viscosity, erythrocyte deformability, Mexidol (2-ethyl-6-methyl-3-hydroxypirinate), treatment of brain ischemia.

Changes in the cognitive sphere during aging in the Russian population are not understood enough.

The purpose of the study is to evaluate the dynamics of indicators of cognitive functions (KF) in two serial dimensions over 9 years in the city population of medium, elderly and senile age and their relationship with the level of education.

Patients and methods. The random population sample of men and women is 45–69 years old, residents of Novosibirsk (n = 9360; the Hapiee project) was examined. CF testing is performed by standard methods. A repeated examination was carried out in a random subsidiary (n = 1663) included in this analysis. The average observation period was 8.8 years (SD = 1.1).

Results and discussion. In the test on semantic fluency of speech, a dynamic decrease was revealed in all age groups, more pronounced in women than in men (p <0.001). Persons 70 years and older have a negative dynamics of memory indicators, semantic speech activity and concentration of attention (p <0.001). In persons with primary (8th and less classes of high school; 6%) and professional (26%) levels of education, a high speed of reducing indicators in the test of delayed reproduction (p = 0.011; 0.038) was revealed than in persons with higher education (35%). Conclusion. It was established that the dynamic reduction of the KF begins at the age of 55–59 years, it is more pronounced in a group of people 70 years and older. The age regression of the memory function was accelerated by participants with a low level of education.

Resume:
The purpose of the study is to assess the influence of intravenous administration of Mexidol during the “therapeutic window” on the effectiveness of intravenous thrombolytic therapy (TLT). Patients and methods. A retrospective study includes 123 patients with an ischemic stroke (AI) who conducted intravenous TLT in the conditions of the vascular centers of the Republic of Tatarstan. To assess the dynamics of neurological status, they used the scale of the severity of the National Institute of Health (National Stroke Scale (Nihss). Depending on the initial severity of the neurological deficiency, all patients were divided into three subgroups: with mild severity (Lee) and an assessment by NIHSS at admission <8 points; with moderate severity (si) - with an assessment> 8 and <16 points; With heavy AI (TI) - with an assessment> 16 points. X -ray computed tomography was performed by all patients at the time of admission, 24 hours after the TLT, as well as with a deterioration in the condition. Results. The use of Mexidol at the prehospital stage, followed by TLT in patients with AI positively affects the regression of neurological deficiency, regardless of the severity of the disease. Reliable differences in the degree of regression of the neurological deficiency according to NIHSS 24 hours and 10 days after receipt of patients with TI who were introduced by Mexidol at the prehospital stage were revealed and who did not receive this drug before the implementation of TLT. The use of Mexidol before TLT promotes greater regression of neurological deficiency. A lower frequency of development of hemorrhagic transformations has been established in patients who received Mexidol at the prehospital stage, in comparison with patients who did not use this drug. Conclusion. The data obtained demonstrate the positive effect of Mexidol on the effectiveness and safety of TLT in patients with AI.
