Abstract
AIM To evaluate the efficiency of long-term use of trospium chloride (Spazmex) for the treatment of patients with neurogenic overactive bladder due to Parkinson's disease (PD) and to determine the influence of therapy on the cognitive status of patients. MATERIALS AND METHODS 60 patients with PD and neurogenic overactive bladder with stages 2.5, 3 and 4 according to Hoehn-Yahr scale were included in the main group. The mean age was 58.2+/-5.7 years. All patients were prescribed trospium chloride at entry into the study, with doses titrated gradually according to clinical efficacy (30 to 90 mg). The comparison group included 15 patients with PD and neurogenic overactive bladder at stages 2,5 and 3, who received tibial neuromodulation according to the standard technique with skin electrodes. The mean age of patients was 56.4+/-4.6 years. At baseline, both groups were comparable in terms of gender, age and cognitive status (p=0.801). All patients received treatment for 52 weeks. The efficiency of therapy was assessed according to bladder diaries, while safety outcomes included postvoid residual, side effects, cognitive status according to the MoCA scale and quality of life according to the SF-Qualiveen questionnaire. RESULTS clinical efficacy and satisfaction were achieved in all patients who completed the study (47 patients in the main group and 15 patients in the comparison group). Good clinical efficacy was demonstrated in both groups, since there was a decrease in the number of urinations, episodes of urgency and urinary incontinence. In addition, there was an improvement in the quality of life according to the SF-Qualiveen scale. The cognitive status during the entire follow-up period remained without significant changes in both groups. CONCLUSION Trospium chloride is an effective drug in patients with PD. It does not affect cognitive functions during long-term use. Trospium chloride should be considered as first-line drug in those with urologic manifestations of PD.

Abstract
Stanford neuromodulation therapy (SNT) is the state-of-the-art magnetic stimulation protocol that has been developed for management of treatment-resistant depression (TRD). The study was aimed to assess the possibility of SNT implementation in clinical practice and to define the protocol safety and efficacy in patients with TRD being an episode of the recurrent depressive disorder or bipolar disorder at the independent center. The study involved six patients (among them three women aged 21–66) with TRD associated with recurrent depression and type 1 or 2 bipolar disorder. The patients received intermittent theta-burst stimulation in accordance with the SNT protocol for five days: applying 10 triple blocks of stimulation daily at intervals of 1 hr between the blocks to the selected stimulation site showing maximum negative functional connectivity with subgenual cingulate cortex within the left dorsolateral prefrontal cortex. The Montgomery–Asberg Depression Rating Scale (MADRS) was used for clinical assessment of the effects, the follow-up period was three months. The improvement of depressive symptoms to the levels characteristic of remission immediately after the SNT completion was observed in five patients (MADRS score ≤10). After three months, two patients still had remission, the condition of three patients met the criteria of mild depressive episode, and one female patient withdrew from the study due to logistical difficulties. No serious adverse events were reported. The findings confirm safety and potentially high efficacy of SNT, including in patients with type 1 and 2 bipolar disorders.

Abstract
Balance impairment at advanced age is a serious medical problem that often has significant implications and affects the quality of the patient’s life. Among the underlying causes are overall slowness of motor response and vestibular syndrome. Virtual reality exergames, including reaction and balance training, hold promise for managing balance dysfunction. The aim of this study was to investigate the effects of a combination rehabilitation program containing elements of virtual reality exergame on the postural and psychophysiological parameters of elderly patients with small vascular disease The study was conducted in 24 patients with small vascular disease (median age: 66 years). All patients underwent a virtual reality rehabilitation program. Psychophysiological, postural and clinical evaluations were performed at baseline and after the program was completed. Balance function measured on the Berg scale improved significantly and was 53 [52; 55] after the training program vs 50 [45; 54] at baseline (p < 0.05). The strategy of balance control also changed: the Romberg ratio was 266 [199.5; 478.5] before rehabilitation and 221 [149.25; 404] after the program was completed (p < 0.05). The most pronounced changes in the measured psychophysiological parameters occurred in the simple audiomotor reaction, which improved from 210 [174.25; 245.5] at baseline to 180.5 [170.5; 208] after rehabilitation (p < 0.05). Thus, the combination balance and reaction virtual reality training is an effective rehabilitation method for advanced-age patients with balance impairment.

Abstract
Multiple sclerosis is a common cause of disability among young and middle-aged people. Despite the modern possibilities of diagnostics and therapy, over time, the disease acquires a secondary progressive character. Rehabilitation of patients at all stages of the disease plays an important role in improving well-being, improving the quality of life, adapting the patient and restoring motor skills. However, there is currently no clear recommendation for the application of specific techniques in each case. The aim of this work was to analyze the available methods of rehabilitation therapy, to highlight the most used and promising ones. Due to the progressive course of the disease, the benefits of rehabilitation measures are usually higher at the initial stages. Nevertheless, nowadays there is a large number of works devoted to rehabilitation measures in patients with moderate and high levels of disability. It has been shown that both inpatient and outpatient rehabilitation has a positive effect on the quality of life and improvement of clinical indicators. Our review describes the main techniques with recommendations for the scheme of application. A comprehensive assessment of the patient's health status, a multidisciplinary team and a personalized approach increase the quality and effectiveness of rehabilitation measures. We also describe our own experience in the treatment of spasticity in patients with a secondary progressive multiple sclerosis.

Abstract
Repetitive transcranial magnetic stimulation (rTMS) is an alternative treatment option for patients with drug-resistant trigeminal neuralgia (TN). However, the effect of rTMS is variable. The aim of this study was to find neuroimaging biomarkers of clinical efficacy of navigated rTMS. Seventeen patients with TN (14 women and 3 men, median age 56 years) received 10 sessions of high-frequency rTMS of the motor cortex contralateral to pain side. The data were analyzed for correlations between functional connectivity (FC), the grey matter (GM) volume and the reduction in pain intensity. Positive correlations were established between the reduction in average pain intensity and GM volume in caudate nuclei in both hemispheres (p(unc) = 0.03), both cerebellar hemispheres (p(unc) = 0.002) and the postcentral gyrus contralateral to pain side (p(unc) = 0.005); between the reduction in peak pain intensity and GM volume in the caudate nucleus contralateral to pain side (p(unc) = 0.04) and the cerebellar hemisphere ipsilateral to pain (p(unc) = 0.03). Significant positive correlations were discovered between the reduction in average pain intensity and FC between the thalamus contralateral to pain side, the postcentral gyrus and the insular operculum (both ipsilateral to pain side; (p(FWE) = 0.018), as well as between the cingulate cortex and the anterior cingulate cortex ipsilateral to pain (p(FWE) = 0.017), between the contralateral subcallosal gyrus and the cerebellar hemisphere ipsilateral to pain (p(FWE) = 0.018). A negative correlation was established for FC between the contralateral putamen and the occipital lobes in both hemispheres (p(FWE) = 0.001). Our findings may spur the development of individual predictors of rTMS efficacy in patients with chronic pain.

Abstract
OBJECTIVE To study diagnostic and therapeutic values of transcranial magnetic stimulation (TMS) in writing cramp (WC). MATERIAL AND METHODS Twelve right-handed patients with WC were enrolled in the study. All patients underwent low-frequency repetitive TMS (rTMS) of the premotor cortex of contralateral to affected hand hemisphere. The clinical efficacy was assessed using the Writer's Cramp Rating Scale (WCRS) and the Medical Outcomes Study-Short Form (MOS-SF-36). Before and after last rTMS session, motor mapping of Abductor pollicis brevis muscle (APB) was performed using navigated TMS (nTMS). Localization, area, and amplitude-weighted area of the APB muscle cortical representations were compared with the healthy controls. After the rTMS course, the dynamics of the studied parameters was assessed. RESULTS Ten sessions of low-frequency rTMS of premotor cortex reduced the severity of WS clinical symptoms with a duration of effect of at least 1 month (p<0.05). There was no statistically significant difference between the area and the weighted area of cortical muscle representations between patients and healthy controls or in patients before and after rTMS. When assessing the localization of cortical muscle representations, two trends were noted: in 4 patients, the localization remained stable, with a shift in the center of gravity of less than 4 mm; in the other 8 patients, a shift in the center of mass of more than 5 mm was noted. No significant correlation between the stability of the cortical muscle representations (the magnitude of the shift in the center of gravity) and the improvement on the WCRS were found. CONCLUSION The low-frequency rTMS of the premotor cortex of the contralateral to affected hand hemisphere can be used as an adjuvant therapy for WC. The TMS-motor mapping study did not show its diagnostic value.

Abstract
The key factor promoting post-stroke gait disturbances is motor impairment of the ankle joint (AJ) which results in pathological synergies. Robotic devices used for gait training are equipped with hip and knee joint actuators. However, there is no consensus in the literature on their effect on AJ movements. The aim of this study was to investigate the effect of robot-assisted gait training on AJ movements in patients with post-stroke paresis. The study recruited 22 hemispheric stroke survivors. They motor function was assessed using clinical scales and motion capture analysis. All patients received 11 robot-assisted gait training session. After rehabilitation, the total score on the Fugl-Meyer Assessment scale increased from 146.5 to 152 points (p < 0.05); for the lower limb, the score increased from 18 to 20.5 points (p < 0.05). The muscle tone of ankle extensors decreased from 2.5 to 2.0 points on the modified Ashworth scale (p < 0.05). The duration of the stance phase increased from 28.0 to 33.5% relative to the total gait cycle (GC). The main difference in the GC structure before and after rehabilitation is the presence of 3 GC parts instead of 5, suggesting consolidation of patients’ goniograms at 1-61% of GC. Comparison of joint angles before and after rehabilitation revealed that only the interquartile ranges (IR) were different (р < 0.05). The authors conclude that robot-assisted training with knee and hip joint actuators indirectly affects the kinematic parameters of AJ by promoting a shift towards the average gait kinematics.

Abstract
Transcranial magnetic stimulation (TMS) is one of rehabilitation approaches for patients with chronic disorders of consciousness (DOC). The aim of our study was to assess neurotrophic factors and the changes of those after TMS course in patients with chronic DOC. We enrolled 26 patients with chronic DOC of various etiology and 21 heathy volunteers. Blood serum and cerebrospinal fluid (CSF) were collected from all patients before and after the TMS course, the levels of BDNF, NSE, NGF, РDGF, GDNF and NT3 were assessed in the biomaterial. The blood BDNF, NSE, PDGF, GDNF and NT3 in patients with chronic DOC were higher compared to healthy volunteers (p < 0.05). We found no correlations between the type of DOC and neurotrophic factors concentrations in blood and CSF. The CSF level of BDNF in patients after traumatic brain injury (TBI) was higher compared to patients with non-traumatic chronic DOC (p < 0.05). We also found the increase of CSF BDNF after the TMS course in patients after TBI (p < 0.05). No other significant differences between groups and another blood and cerebrospinal fluid biomarker levels were detected. Thus, the serum BDNF, NSE, PDGF, GDNF and NT3 levels in patients with chronic DOC were higher compared to healthy volunteers. The BDNF level in CSF was higher in patients with traumatic DOC, and it also increased after the course of high-frequency TMS in this group. This fact may indicate the long-term neuronal plasticity processes in patients after TBI, as well as more favorable rehabilitation prognosis.

Abstract
OBJECTIVE To evaluate therapeutic effects of navigational dual-target high-frequency rTMS over the primary motor (M1, bilateral) and the left dorsolateral prefrontal cortex (DLPFC) on clinical dynamics of Parkinson's disease (PD) symptoms in a parallel placebo-controlled study. MATERIAL AND METHODS The study included 46 patients randomized into equal therapeutic and placebo rTMS groups. Navigational therapeutic and placebo10 Hz rTMS was applied over the M1 and DLPFC areas (20 daily sessions, for 3 weeks). Assessment of the dynamics of clinical symptoms was performed using the MDS UPDRS scale (Parts I-IV) before the first session, immediately after 20 sessions, and 4-6 weeks after the rTMS course. Non-motor and mental symptoms were assessed using the Hamilton Depression Rating Scale (HDRS-17), Beck depression inventory (BDI-II), Depression, Anxiety and Stress (DASS-21) scales and the Mini Mental State Examination (MMSE). RESULTS Significant therapeutic effects of rTMS compared to placebo were established: a greater decrease in overall score on the MDS-UPDRS scale (parts I-IV), a decrease in the severity of non-motor (part I) and motor symptoms (part III, with a large therapeutic effect for the symptoms of rigidity, bradykinesia and postural instability), as well as the severity of motor complications of dopamine replacement therapy (part IV). The effects of rTMS on motor symptoms persisted 4 weeks after the end of the stimulation course. It is also important to note significant positive dynamics in both rTMS and placebo groups in the form of comparable reduction in the severity of everyday motor symptoms (MDS-UPDRS part II), improvement of the total scores on MMSE, HDRS, BDI-II, DASS-21. CONCLUSIONS The dual-target high-frequency rTMS over the primary motor cortex (bilateral) and the left dorsolateral prefrontal cortex has positive therapeutic effects on the motor and affective symptoms of Parkinson's disease, which are significantly stronger than that of the placebo stimulation.

Abstract
High-frequency repetitive transcranial magnetic stimulation (rTMS) is approved by the Food and Drug Administration (FDA) for the treatment of pharmacotherapy-resistant depressive disorders (DD). Individual target determination for stimulation can be one of the approaches that can increase the efficiency of the technique. Objective: to compare of the effectiveness and tolerability of standard and personalized rTMS protocols.Patients and methods. The investigation enrolled 30 patients with pharmacotherapy-resistant DD who were pseudo-randomized into two groups matched for age, gender, and episode severity. In the study group, the target was located at a point within the left dorsolateral prefrontal cortex (DLPFC) with maximum negative functional connectivity of the subgenual cingulate cortex. In the control group, the stimulation point was 5 cm anterior to the primary motor cortex (hand area). All the patients underwent 20 sessions of high-frequency rTMS DLPFC. For clinical evaluation, the investigators used the Beck Depression Inventory (BDI) and the 36-item Short Form Health Survey (SF-36) questionnaire before and after 10 and 20 rTMS sessions, respectively. Tolerability was assessed using the standardized questionnaires during and within 24 hours after each session. Results and discussion. The study group showed a significant reduction in BDI scores and an increase in the SF-36 (“Mental Health” section) scores after both 10 and 20 rTMS sessions; the control group had those only after 20 sessions. The two groups exhibited no significant differences in the reduction of BDI scores before and after 10 and 20 sessions, respectively. The investigation can be considered to be pilot in searching for algorithms to enhance the efficiency of rTMS DLPFC in pharmacotherapy-resistant depression using the algorithm for personification of target selection. It demonstrated the more rapid onset of a clinical effect in the study group patients. No serious adverse events were reported. The patients had dizziness, headache, and contraction of the facial muscles during the session; headache and mood changes within 24 hours after it. Conclusion. In both groups, rTMS was satisfactorily tolerated and effective; however, personalized target selection accelerated the onset of a clinical effect.

Abstract
AIM To evaluate the clinical efficacy of BCI-supported mental practice and to reveal specific cognitive impairment which determine mental practice ineffectiveness and inability to perform MI. MATERIAL AND METHODS Fifty-five hemiplegic patients after first-time stroke (median age 54. 0 [44.0; 61.0], time from onset 6.0 [3.0; 13.0] month) were randomized into two groups - BCI and sham-controlled. Severity of arm paresis was measured by Fugl-Meyer Assessment of Motor Recovery after Stroke (FMA) and Action Research Arm Test (ARAT). Twelve patients from the BCI group were examined using neuropsychological testing. After assessment, patients were trained to imagine kinesthetically a movement under control of BCI with the feedback presented via an exoskeleton. Patients underwent 12 training sessions lasting up to 30 min. In the end of the study, the scores on movement scales, electroencephalographic results obtained during training sessions were analyzed and compared to the results of neuropsychological testing. RESULTS Evaluation of the UL clinical assessments indicated that both groups improved on ARAT and FMA (sections A-D, H, I) but only the BCI group showed an improvement in the ARAT's grasp score (p=0.012), pinch score (p=0.012), gross movement score (p=0,002). The significant correlation was revealed between particular neuropsychological tests (Taylor Figure test, choice reaction test, Head test) and online accuracy rate. CONCLUSION These results suggest that adding BCI control to exoskeleton-assisted physical therapy can improve post-stroke rehabilitation outcomes. Neuropsychological testing can be used for screening before mental practice admission and promote personalized rehabilitation.

Abstract
OBJECTIVE To perform an in-depth prospective analysis of the prevalence, risk factors, specific characteristics of venous thromboembolism (VTE) and the dynamics of venous thrombosis during the treatment with low-molecular-weight heparin (LMWH) in patients with different forms and severity of Guillain-Barre syndrome (GBS) admitted to an intensive care unit (ICU). MATERIAL AND METHODS Prevalence, risk factors and course of VTE were analyzed for the first time in 65 ICU inpatients with various forms and severity of GBS. Neurological status was evaluated at baseline and in dynamics, duplex scanning of veins of the legsin the system of inferior vena cava was performed. RESULTS AND CONCLUSION Despite the preventive using of LMWH, a half of patients with GBS, regardless of the form of the disease during the progression of neurological symptoms, have VTE (deep vein thrombosis--52%, pulmonary embolism--15%). Significant risk factors include: severe disease course requiring artificial ventilation, bed rest for more than 3 days, infectious complications, the presence of the catheter in the central vein, age over 40 years. Venous thrombosis in the system of inferior vena cava in patients with GBS does not differ from that in other critical illnesses suggesting that this pathological process is universal. Preventive measures for this category of patients is insufficient and requires a search for other prevention strategies.

Abstract
BACKGROUND the relevance of this study arises from the high prevalence of upper limb motor impairment and pathological synergy in the post-stroke patients; these conditions are very difficult to correct with the use of the traditional rehabilitation methods. A promising but insufficiently studied approaches are the virtual reality (VR) technology as well as its combination with other techniques. AIM The objective of the present study was to evaluate the influence of the training making use of the mechanotherapeutic system on the motor function of the paretic hand. MATERIAL AND METHODS A total of 30 patients were enrolled in this study. The main group comprised 20 of them who completed the training course on the mechanotherapeutic system allowing for separate adjustment of weight support for the shoulder and the forearm, VR feedback with individual setting of the active working space, and augmented functional exercises. The control group consisted of the patients (n=10) who performed the task-oriented motor training course of an equal duration with arm weight support and visual feedback. RESULTS AND DISCUSSION The assessment based on the Fugl-Meyer scale (FMA) showed the statistically significant changes in the passive motion range in the patients of both groups, but only those comprising the main group were found to experience the improvement of the major movements of the arm, wrist, and hand as well as movements outside synergy (p<0.005). Fine motor skills estimated from the results of the Action Research Arm test (ARAT) improved only in the main group due to the cylindrical and pinch grip (p<0.005). Also, only patients of the main group, improved daily living skills evaluated based on the Frenchay Arm test (FAT) (p<0.005). CONCLUSION The results of the present study give evidence that the use of combined training with arm weight support and VR feedback contributes to a more complete recovery of motor and daily living skills in the upper limb of post-stroke patients, compared to the classical task-oriented training with visual feedback.

Abstract
The mechanisms underlying the locomotion recovery in poststroke patients remain unknown. Navigated transcranial magnetic stimulation (nTMS) is a new method to evaluate the functional state of the motor system. Using of the exoskeleton complex (EC) allow to correct walking pattern significantly. The aim of this study was to evaluate the capability of nTMS to assess changes in gait cortical control using EC in poststroke patients. 14 patients suffered subcortical stroke, mean age was 53.0 years [49, 62], mean duration of a stroke of 14.2 [7.0; 23.0] months were included. All patients trained with EC for 10 times and also received standardized physical therapy. All patients underwent nTMS, as well as clinical assessment using a Fugl-Meyer Scale lower extremity section and 10 m walking test before and after trains. A significant decrease of time to walk 10 meter was observed, while Fugl-Meyer Score remained unchanged. Patients showed the significant reduction of the average latency of motor responses from the affected hemisphere and different patterns of size and localization changes in both legs' cortical motor areas. Navigates TMS may demonstrate individual patterns of changes in cortical representation of leg muscles in post-stroke patients with damage of various motor system elements, while using exoskeleton complex. Thus, navigated TMS may be used not only for verification of neuroplasticity process, but it may also provide its detailed description.

Abstract
The article discusses the effect of a course of treatment with the use of multimodal complex exoskeleton (MCE) "Regent" on the reorganization of cortical locomotor zones in 14 patients with post-stroke hemiparesis, mainly atthe chronic stage of the disease. Before the course of treatment, we identified specific areas of activation in the primary sensorimotor and supplementary motor areas and the inferior parietal lobules in both affected and healthy hemispheres by means of functional MRI (fMRI) with the use of special passive sensorimotor paradigms. After the course of treatment with MCE, we observed an improvement of temporal characteristics of walking; it was accompanied by a decrease in the activation zones of inferior parietal lobules, especially in the healthy hemisphere, and by a significant increase in the activation zone of primary sensorimotor and supplementary motor areas. The analysis of the functional connectivity of studied zones before and after the course of treatment with MCE showed significant changes in intra- and interhemispheric interactions.

Abstract
UNLABELLED Spasticity is considered to be a common manifestation of multiple sclerosis. Muscle relaxants are not sufficiently effective; more than that, some of them often cause a variety of adverse reactions. Transcranial magnetic stimulation (TMS) can be a promising new tool for the treatment of spasticity. The objective of the present study was to compare the effectiveness of the two TMS protocols: rhythmic (high-frequency) TMS (rTMS) and stimulation with the theta bursts (iTBS) in terms of their ability to reduce spasticity in the patients presenting with multiple sclerosis. PATIENTS AND METHODS Twenty two patients with secondary-progressive multiple sclerosis were pseudo-randomized into two groups: those in the first (high-frequency) group received the treatment with the use of rTMS therapy at a frequency of 10 Hz; the patients of the second group, underwent stimulation with the theta bursts (iTBS). All the patients received 10 sessions of either stimulation applied to the primary motor area (M1) of both legs. The effectiveness of TMS protocols was evaluated before therapy and after 10 sessions of stimulation based on the Modified Ashworth scale (MAS), the expanded disability status scale (EDSS), and the Kurtzke functional scale (Kfs). In addition, the patients were interviewed before treatment, after 10 rTMS sessions, immediately after and within 2 and 12 weeks after the completion of the treatment using questionnaires for the evaluation of spasticity (SESS) , fatigue, and dysfunction of the pelvic organs (severity of defecation and urination disorders), fatigue. RESULTS The study has demonstrated a significant reduction in spasticity in the patients of both groups at the end of the TMS protocol based on the MAS scale. There was no significant difference between the outcomes of the two protocols. Both had positive effect on the concomitant «non-motor» symptoms (fatigue, dysfunction of the pelvic organs). CONCLUSION High-frequency transcranial magnetic stimulation (10 sessions of rTMS therapy at a frequency of 10 Hz) and stimulation with the theta-bursts applied to the M1 area in both legs can be an effective alternative treatment of spasticity in the patients with secondary-progressive multiple sclerosis. Further research is needed to detect more accurately the differences between the outcomes of the two stimulation protocols and the development of indications for their application on an individual basis.

Abstract
Motor imagery is suggested to stimulate the same plastic mechanisms in the brain as a real movement. The brain-computer interface (BCI) controls motor imagery by converting EEG during this process into the commands for an external device. This article presents the results of two-stage study of the clinical use of non-invasive BCI in the rehabilitation of patients with severe hemiparesis caused by focal brain damage. It was found that the ability to control BCI did not depend on the duration of a disease, brain lesion localization and the degree of neurological deficit. The first step of the study involved 36 patients; it showed that the efficacy of rehabilitation was higher in the group with the use of BCI (the score on the Action Research Arm Test (ARAT) improved from 1 [0; 2] to 5 [0; 16] points, p = 0.012; no significant improvement was observed in control group). The second step of the study involved 19 patients; the complex BCI-exoskeleton (i.e. with the kinesthetic feedback) was used for motor imagery trainings. The improvement of the motor function of hands was proved by ARAT (the score improved from 2 [0; 37] to 4 [1; 45:5] points, p = 0.005) and Fugl-Meyer scale (from 72 [63; 110 ] to 79 [68; 115] points, p = 0.005).

Abstract
This review highlights the achievements in the field of autoimmune diseases of the nervous system over the last 15 years. It became possible to deepen the understanding of medical and social significance of these diseases, form the concept of nosologic unit heterogeneity, describe new and atypical forms ofdemyelinating diseases of the central and peripheral nervous system, autoimmune diseases of the neuromuscular synapse. Also, it is important to mention, that the new antigens were identified, the diagnostic panel of autoantibodies was developed and put into practice. Furthermore, the dinical practice guidelinesfor the diagnosis and management of patients were developed, the new drugs were tested and included in these guidelines. The scientists of the biggest Russian neurological centre, Research Centre of Neurology (Moscow), developed a <<vaccine>> for immunotherapy of multiple sclerosis, studied pathomorphosis of Guillain-Barre syndrome, specified the components of its pathogenesis, improved the programs of pathogenetic therapy, which led to the decrease in mortality from 30 to 3%, helped to decrease the A VL period by 2 times, hasten the recovery of independent walking by 2.5 times. Nowadays different biomarkers of diseases of the central and peripheral nervous system are studied and modern technologies in neurorehabilitation are applied.

Abstract
Time-of-flight MALDI mass spectrometry (MALDI-TOF-MS) profiling of blood serum of patients with Guillain-Barré syndrome (GBS, 36 samples), chronic inflammatory demyelinating polyneuropathy (CIDP, 24 samples) and practically healthy donors (HD) (35 samples) was carried out in order to identify potential biomarkers of autoimmune demyelinating polyneuropathies (ADP). To simplify the peptide-protein mixture of serum prior to MALDI-TOF-MS analysis samples were pre-fractionated on magnetic microparticles with a weak cation-exchange (MB-WCX) surface. Comparative analysis of mass spectrometric data using the classification algorithms (genetic and neural network-controlled) revealed a characteristic set of peaks, agreed change area with a high specificity and sensitivity of the differentiated mass spectrometry profiles of the blood serum of patients with DPNP and healthy donors (for GBS values of these characteristics reached 100 and 100, and for CIDP 94.1 and 100% respectively). Comparative analysis of mass spectrometric profiles of serum samples obtained from patients with GBS and CIDP, allowed to build a classification model to differentiate these diseases from each other, with a specificity of 88.9 and a sensitivity of 80%.

Abstract
Two-year experiments were performed to evaluate the neurotrophic effect of hypoxia-inducible factors (vascular endothelial growth factor and angiogenin) expressed in recombinant human adenoviruses in amyotrophic lateral sclerosis. Randomized placebo-controlled trial demonstrated safety and good tolerability of the recombinant antiviral drugs. The life span of patients under conditions of hypoxia increased after treatment with the test drug, which was probably related to improved resistance of motoneurons. The presence of virus-neutralizing antibodies decreases the effectiveness of adenoviral vectors, which necessitates differential approach to the selection of patients and continuous monitoring of gene therapy.
