This article presents a review of Russian and foreign literature about the impact of arterial hypertension (AH) on the risk of cognitive impairment and dementia. Large studies have demonstrated the effect of blood pressure (BP) on the risk of vascular dementia and Alzheimer’s disease (AD) in elderly and oldest old people as well as a role of antihypertensive therapy. There is evidence of a negative effect of hypertension in middle age on cognitive functions in late-life. Observational studies as a whole have shown the positive effect of antihypertensive therapy on the prevention of cognitive function and dementia. However, there are a number of limitations that dictate the need for further research on this issue. The importance of the interdisciplinary approach to treatment of cognitive impairment by cardiologists and/or therapists, together with neurologists, as well as complex treatment regimens, including correction of risk factors and neuroprotective therapy, is highlighted.

There are multiple common mechanisms in chronic pain and cognitive impairment. However, the presence, prevalence and clinical burden of such impairment are frequently underestimated. Objective: to evaluate subjective and objective cognitive deficits in patients with chronic migraine (CM). Materials and methods. We recruited 53 subjects with CM and 22 gender- and age-matched controls with low-frequency episodic migraine (a maximum of 4 headache days per month) aged 18-59. All patients filled in the HADS (Hospital Anxiety and Depression Scale) anxiety and depression scale and Pittsburg Sleep Quality Inventory (PSQI). Cognitive function was assessed with Montreal Cognitive Assessment (MoCA), Digital Symbol Substitution Test (DSST), Rey Auditory Verbal Learning Test (RAVLT) and the Perceived Deficits Questionnaire (PDQ-20). Results. 56 % of patients with CM complained of memory problems. Decreased cognitive function was also observed during self-assessment using the PDQ-20 questionnaire. Objectively, we found a significant decrease in 90-second DSST results and RAVLT total recall and learn ing rates. 44 % of subjects with CM scored lower than 26 points on MoCA. Most frequently we found impairments in attention (75 %), memory/delayed recall (50 %), language (50 %) and executive function (37 %). Depression and sleep quality correlated with only several parameters of cognitive tests. Conclusion. Subjective and objective cognitive deficits are prevalent in the CM population. Most often memory and attention are impaired. Cognitive complaints need to be carefully assessed, and treatment of such impairment may improve quality of life and decrease disability in CM.

However, the role of the mechanisms of inflammation and angiogenesis in the origin of CI is unclear, as is its relationship to the number and localization of foci during a neuroimaging examination. Objective: to investigate the relationship between the presence of CI, focal brain tissue changes, and the plasma and serum levels of vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1) in patients with CCI. Patients and methods. Examinations were made in 59 patients with CCI and in 20 apparently healthy individuals. The investigators evaluated the cognitive status using the Mini-Mental State Examination (MMSE) and the clock drawing test), performed brain magnetic resonance imaging (MRI), duplex scanning of cerebral vessels, and determined laboratory indicators: the serum levels of MCP-1 and C-reactive protein, and the serum and plasma concentrations of VEGF. Results. The patients with CI were found to have higher values of inflammatory markers, lower serum and plasma concentrations of angiogenic factors, and a greater number of focal changes on MRI than those without CI (5.06±0.23 and 2.36±0.3 scores, respectively; p(0.05). Imbalance of angiogenic and antiangiogenic factors can cause disease progression and moderate vascular CI in patients with CCI.

Anxiety disorders are an important biomedical problem due to the high prevalence and significant negative impact on the quality of life and the course of concomitant somatic and neurological diseases. Cognitive impairment (CI) is one of the most intensively studied aspects of pathological anxiety. Impairments in attention, executive functions, memory, cognitive deficit, as well as abnormal cognitions and metacognitions are identified in anxiety disorders. Moreover, the treatment of the latter with the most frequently used drugs (antidepressants, atypical antipsychotics, anticonvulsants, tranquilizers) does not lead to a significant improvement in cognitive functions, and often contributes to their worsening. In this connection, in addition to psychotherapy, cognitive function-improving agents play a large role in treating anxiety diseases associated with cognitive dysfunction. Ginkgo Biloba extract (EGb 761, Tanakan®) that positively affects cognitive functions, especially in the domains of memory, concentration and attention deserves special attention.

The paper presents the proceedings of the Round Table with the participation of leading neurologists, which is devoted to chronic cerebrovascular diseases. It is noted that chronic cerebral ischemia (CCI), or dyscirculatory encephalopathy (DEP), is one of the most common neurological diagnoses in our country. The pathogenesis, clinical presentations, diagnosis and treatment of CCI (DEP) and its matching with vascular cognitive impairment (CI), which is regarded in foreign literature as the main manifestation of chronic cerebrovascular disease (CVD) were considered. The authors analyze clinical trials evaluating the efficacy of vinpocetine (Cavinton) in chronic CVD, dizziness, Cl, as well as the use of new vinpocetine formulations, such as Cavinton Comforte, in various neurological diseases, dysphagia in particular, in poststroke patients.

© Team of authors, 2018. Objective. To investigate the efficacy of divaza in outpatients with cognitive disorders and chronic brain ischemia (CBI). Material and methods. The non-interventional observational program included the data of 2583 outpatients with CBI from 30 cities (8 federal okrugs of the Russian Federation) who were on outpatient neurological treatment and received divaza in a dose of 2 tablets three times a day from Oct 2016 to Jan 2017. Cognitive functions were evaluated using the MoCA scale before and after 3 months of treatment. Results and conclusion. Cognitive disorders were identified in 90.7% of patients (<26 МоСА scores). After treatment, the mean MoCA score increased from 19.58 ± 5.13 to 23.99 ± 4.21 (p<0.0001), the number of patients with normal cognitive functions rate (≥26 scores) increased from 9.3 to 41.3%, the number of patients with marked cognitive impairment decreased. The drug was well-tolerated by old and very old patients, adverse events were observed rarely (0.6% of cases). The majority of doctors (88.4%) noticed the effect of divaza as significant improvement or improvement, and 89.6% of patients valued the effect to be excellent or good. The use of divaza, the drug with endothelioprotective and nootropic effects, is pathogenetically justified and promising in patients with cognitive disorders of vascular etiology.
