[Cognitive impairment and tactics of using the drug Cerebrolysin. Resolution of the International Council of Experts (May 12, 2023)]. / Kognitivnye narusheniya i taktika primeneniya preparata Tserebrolizin. Rezolyutsiya mezhdunarodnogo soveta ekspertov (12 maya 2023 g.).

The aging of the population and the associated increase in the share of cognitive impairments in the structure of a wide range of diseases are a serious challenge for modern healthcare. Difficulties in the treatment of cognitive disorders are determined by many factors, including the age of patients, comorbidity, forced polypragmasia and the adequacy of the dosage of drugs that restore cognitive activity. The experts discussed information about the therapeutic potential of the drug Cerebrolysin in the treatment of cognitive disorders of various origins, stated significant experience of its effective and safe use in many clinical studies in mild and moderate forms of dementia. At the same time, there was a lack of consistent and systematic data on the dosage regimen, frequency, and duration of use of the drug in different forms of cognitive impairment and the degree of their severity. The aim of the international council of experts was to determine the optimal dosage regimens of the drug Cerebrolysin in patients with various etiologies and severity of cognitive impairment. The result of the work was the approval of a unified scheme for the use of the drug Cerebrolysin, considering the severity of the disease and its duration.

[Experience of using rhythmic transcranial magnetic stimulation, extracorporeal shock wave therapy and botulinotherapy in individual motor recovery programs in patients with spastic paresis of the lower limb]. / Opyt ispol'zovaniya v individual'nykh programmakh dvigatel'nogo vosstanovleniya ritmicheskoi transkranial'noi magnitnoi stimulyatsii, ekstrakorporal'noi udarno-volnovoi terapii i botulinoterapii u patsientov so spasticheskim parezom nizhnei konechnosti.

Walking disorder is one of the most frequent consequences of stroke and traumatic brain injury, occurring in 80% of cases. Spastic paresis of the muscles of the lower extremity is the cause formed in 20-40% of patients within a few weeks after brain damage. In this case, a complex of symptoms occurs: motor deficiency (muscle paresis), increased muscle tone (spasticity), biomechanical changes in muscles, joints and surrounding tissues, contractures. Recovery of walking is a difficult task due to the peculiarities of its organization in the norm. At the same time, changes occurring in the muscles of the lower limb after a stroke, their modular reorganization, the formation of various pathological patterns, violation of the regulation of movements by the central nervous system, rapidly occurring changes in muscles, ligaments, complicate this process. Improving walking is one of the most important priorities of rehabilitation. Already at the second (stationary) stage of rehabilitation, patients have a lack of proper support on the lower limb, which inevitably leads to excessive load on the second limb, a change in the body scheme, incorrect foot placement, violation of the mechanics of walking (moving from heel to toe) due to plantar flexion / turn of the foot, etc. All this makes patients dependent on outside help, and walking unsafe, increases the risk of falls and complications (arthropathy, contracture, etc.). In this regard, it is important to timely diagnose the totality of changes in the lower limb and create optimal comprehensive rehabilitation programs using highly effective treatment methods aimed at reducing the severity of the motor defect, reducing spasticity and preventing complications. The article discusses the place of rhythmic transcranial magnetic stimulation, extracorporeal shock wave therapy and botulinum therapy during rehabilitation in patients with spastic paresis of the lower limb after a stroke. The results of the protocol of clinical approbation «Complex rehabilitation of patients with lower limb spasticity after focal brain damage at the second stage of medical rehabilitation¼ are presented.

The review discusses the data on efficacy and safety of reperfusion therapy and neuroprotective therapy in ischemic stroke (IS) and during the rehabilitation. The authors recommend using an individual approach to the treatment of patients with acute IS and identify patients in whom neurotrophic therapy will bring the greatest effect. In addition, it is concluded that pharmacological support is an integral part of the rehabilitation of patients after a stroke, along with the correct assessment of neurological deficits, the timely start of rehabilitation measures, the complexity and continuity at all stages.

[Safety and efficacy of the Relatox in the treatment of patients with cervical dystonia (results of a multicenter simple blind comparative randomized study)]. / Bezopasnost' i effektivnost' preparata Relatoks v lechenii patsientov s tservikal'noi distoniei (rezul'taty mul'titsentrovogo prostogo slepogo sravnitel'nogo randomizirovannogo issledovaniya).

OBJECTIVE: The analysis of evaluation of the efficacy and safety of Relatox in patients with cervical dystonia (CD). MATERIAL AND METHODS: Russian multicenter simple comparative randomized clinical trial. The study involved 180 patients of both sexes aged 18-65 years from 3 research centers of the Russian Federation. All patients had previously established diagnosis of CD and were randomized to one of two groups at 1 visit after the inclusion procedure and signing of informed consent. Patients in group 1 (n=90) got injections of Relatox, in group 2 (n=90) - injections of Botox for the first time or no earlier than 4 months after the previous injection of Dysport 500 units, Botox 200 units or Xeomin 200 units. The assessment of changes in cervical dystonia followed, including of determination of changes in the severity of CD, assessed on the TWSTRS scale by the total score and by the defining values of the blocks, as well as on the scales: the Patient Global Impression of Improvement (PGI-I) and of adverse events (local and systemic reactions). Based on the form of cervical dystonia (torticollis, laterocollis, etc.), the drug was injected under electromyographic control into the target muscles: sternocleidomastoid, belt, trapezoidal, shoulder-lifting muscle. RESULTS: Equal efficacy, good tolerability and safety comparable to the comparison drug Botox was demonstrated in 12 weeks after injection of Relatox. The number of registered local and systemic reactions in both groups was insignificant and did not differ significantly (p>0.05). There were no significant differences in the results of laboratory parameters in patients of both groups (p>0.05). Serious adverse events were also not detected during the study. CONCLUSION: Obtained results indicate the safety, good tolerability and efficacy of Relatox in patients with CD comparable to Botox and can be recomemded for using by practitioners.

[Current issues of treatment and rehabilitation of patients with neurological disorders and the consequences of COVID-19. Resolution of Advisory Board]. / Osnovnye napravleniya lecheniya i reabilitatsii nevrologicheskikh proyavlenii COVID-19. Rezolyutsiya soveta ekspertov.

Last year the global medical community faced the pandemic of the new coronavirus infection caused by SARS-CoV-2. To date, there is considerable expert experience, which indicates that the brain, along with the corresponding respiratory system, is a target organ for a new coronavirus infection. Moreover, a number of symptoms from the central and peripheral nervous system can persist for several weeks, months, and even tens of months. To designate such protracted clinical conditions, a new definition was introduced: «Post-COVID-19 Condition¼. Advisory Board of Neurologists and Rehabilitation Therapists met to, discuss of practical experience and taking into account scientific information about COVID-19, which was available at the time of the meeting, to develop unified approaches for the management of patients with neurological complications and the consequences of a new coronavirus infection. The Advisory Board worked out a resolution in which formulated the tactics of managing patients with neurological manifestations of COVID-19. The substantiation of the importance and expediency of the development and implementation of a special program of clinical examination of patients who have undergone COVID-19, which would include a clinical examination with a detailed assessment of cognitive functions to early identification and diagnosis of neurodegeneration and subsequent therapy, is given.

[Current issues in the rehabilitation of stroke patients against the background of a new coronavirus infection (COVID-19). Resolution of the Council of Experts]. / Aktual'nye voprosy reabilitatsii patsientov s insul'tom na fone novoi koronavirusnoi infektsii (COVID-19). Rezolyutsiya Soveta ekspertov.

The pandemic of the new coronavirus infection caused by SARS-CoV-2 has forced to reconsider the methods of rehabilitation of patients with emergency conditions, including neurology. The Council of Experts of Neurologists and Rehabilitation Therapists gathered to develop unified approaches to manage stroke patients based on a discussion of practical experience and, taking into account the scientific information on COVID-19 that was available by the time of the meeting. Stroke is a serious disabling condition that requires maximum rehabilitation efforts at all stages of medical care. In the context of the SARS-CoV-2 coronavirus epidemic, the process of medical rehabilitation and the routing of patients with stroke is undergoing major changes. Combining COVID-19 and stroke requires new approaches to rehabilitation and patient management. During the meeting, a resolution was developed in which the experts formulated the tactics of medical rehabilitation of patients with stroke and COVID-19 at the first and second stages. The arguments of the importance and practicability of carrying out measures of medical rehabilitation at the third stage is given and the need to continue consultations on the indicated topic is revealed.

[Modern aspects of the pathophysiology of walking disorders and their rehabilitation in post-stroke patients]. / Sovremennye aspekty patofiziologii narushenii khod'by u patsientov posle insul'ta i osobennosti ikh reabilitatsii.

The problem of rehabilitation of post-stroke patients with motor deficit remains relevant with growing prevalence of disability and decreasing mortality, despite all measures aimed at stroke prevention and morbidity reduction. One of the most common consequences of stroke is gait impairment as a result of spastic paresis of the lower limb (decreased gait velocity, shortened step, excessive loading of intact limb etc.), which leads to significant maladaptation, increased risk of falls, decrease in quality of life. The article presents a detailed review of motor action in normal and pathologic conditions, analysis of neuronal structures involved into a movement act in healthy individuals and in stroke patients, current aspects of gait pathophysiology, characteristics of post-stroke gait (speed and asymmetry of gain, balance control impairment). A separate paragraph is devoted to gait recovery after stroke with analysis of existing and developing strategies of rehabilitation, aimed at the improvement of vertical posture, balance control and movement, condition, tone and functioning of skeletal muscles. Authors also analyze new research information on the efficacy of botulinum toxin preparations and programs of Guided Self-Rehabilitation Contracts (GSC), present the results of clinical trials demonstrating the efficacy of combination of these two methods.

[Conversion ratio between different botulinum neuroprotein product in neurological practice]. / Sootnoshenie edinits deistviia razlichnykh preparatov botulinicheskogo neiroproteina pri ispol'zovanii v nevrologicheskoi praktike.

Despite nearly 30 years of experience in the application of botulinum toxin type A (BTA) in clinical practice, many fundamental questions of therapy remain valid. There are 5 botulinum toxin type A used for neurological indications in the Russian Federation in 2017. They contain different number of active neuroprotein (150 kDa) in a therapeutic dose of the drug that may have a potential impact on the efficacy and duration of action. The current SmPC of each BTA stated that the unit of activity is unique and can not be compared with any other BTA. In scientific publications one can find many details concerning the equivalence doses of onabotulinumtoxin A (botox) and abobotulinumtoxin A (dysport) and the ratio of units varies from 1:1 to 1:11. However, according to clinical guidelines, systematic reviews and high quality research evidence of recent years, the ratio of units of abobotulinumtoxin A (dysport) and onabotulinumtoxin A (botox) is 3(2,5):1. Use of a fixed ratio of units is possible only when switching from one drug to another or in case of limiting access to specific drug. Botulinum toxin type A is the first line of therapy in the treatment of several neurological diseases. The most commonly used drugs of botulinum toxin type A (botox, dysport, xeomin) have a significant evidence base that confirms their efficacy and optimal safety profile. The main difference between botulinum toxin type A is their potential activity of action, i.e., activity units and total therapeutic dose.
