[Features of pharmacotherapy of vascular cognitive impairment in the elderly]

The problem of pharmacotherapy of elderly and senile people is currently extremely relevant due to the aging of the population and the increase in the prevalence of cardiovascular diseases. One of the most serious problems of the elderly is the development of cognitive decline due to cerebrovascular pathology. However, elderly patients often have a large number of comorbid diseases, which leads to difficulties in diagnosing and managing these patients, and often to the development of polypharmacy, which can lead to deterioration in functional status, cognitive impairment, adverse reactions and drug interactions. In addition, in elderly patients, there may be changes in pharmacokinetics and pharmacodynamics due to anatomical and physiological involutive processes. At the same time, the number of drugs whose clinical efficacy and tolerability were evaluated specifically in elderly and senile patients is relatively small. In a randomized clinical trial of sequential parenteral and oral therapy with Mexidol in patients with mild vascular cognitive impairment syndrome, a positive effect of this therapy on various domains (cognitive, emotional, autonomic, motor) of chronic cerebrovascular disease was confirmed compared with placebo, which allows us to recommend it for use in elderly and senile patients.

[Cerebrovascular disease with neurocognitive impairment]

In the International Classification of Diseases 11th revision in the section «Diseases of the nervous system», it is proposed to distinguish «Cerebrovascular disorder with neurocognitive impairment», which corresponds to both discirculatory encephalopathy (DEP) or chronic cerebral ischemia (CCI) accepted in our country, and also vascular cognitive impairments. The terminology, prevalence, risk factors and pathological basis of the disease are discussed, in particular multiple infarctions, strategic infarctions, cerebral small vessel disease, specific microangiopathies, intracerebral hemorrhage and global hypoperfusion. Post-stroke cognitive impairments are discussed in detail. The article presents relevant data on the pathogenesis of the disease, highlights the issues of clinical and neuroimaging diagnostics. Based on the data presented in the article, we can conclude that the diagnosis of DEP, CCI should be based on the presence of cerebrovascular disease with neurocognitive impairment, which implies the verification of vascular cognitive impairments and reliable neuroimaging signs of cerebrovascular pathology while excluding other causes. Early diagnosis and effective treatment of cerebrovascular disease with neurocognitive impairment (DEP, CCI) is becoming increasingly important, since treatment can slow the progression of the disease and lead to a decrease in the incidence of stroke and dementia.

[Cerebrovascular disease in patients with type 2 diabetes mellitus]

The article discusses the current trends in the spread of carbohydrate disorders, discusses in more detail the problem of type 2 diabetes mellitus and associated cerebrovascular diseases. The spectrum of the therapeutic effect of the drugs neurox and neupilept is considered in relation to this category of patients.
