The article considers the influence of α-glycerylphosphorylcholine in the scheme of comprehensive therapy on the dynamics of functional recovery in patients with cerebral hemispheric ischemic stroke. Against the background of the progressive growth of acute cerebral infarction, the problem of timely care is relevant. Timely treatment of stroke, based on evidence-based medicine, along with early activation and rehabilitation of patients is designed to reduce mortality and subsequent disability of patients. Given that cholinergic insufficiency and structural and functional damage of neurons play an important role in the pathogenesis of post-stroke disorders, the use of medicines for their correction, in particular α-glycerylphosphorylcholine, is justified. Choline alfoscerate, a precursor of acetylcholine and phosphatidylcholine, is broken down by enzymes into choline and glycerophosphate when ingested, and the choline thus obtained is able to improve neuronal functionality in patients with neurodegenerative and vascular diseases. The study revealed a significantly better recovery of impaired motor and cognitive functions after cerebral hemispheric stroke under the influence of comprehensive therapeutic and rehabilitation measures using active rehabilitation methods in conjunction with α-glycerylphosphorylcholine. The results obtained during the study allow us to report the advantage of a combination of methods of active rehabilitation and the use of the pharmacological agent α-glycerylphosphorylcholine. The feasibility and efficacy of α-glycerylphosphorylcholine are related to its ability to reduce motor and cognitive deficits after ischemic stroke. The scheme of comprehensive treatment of patients in acute and restorative periods of cerebral hemispheric ischemic stroke with the use of α-glycerylphosphorylcholine helps to increase the effectiveness of functional recovery after an acute cerebral accident, and can be used in the use of therapeutic and rehabilitation programs for patients after cerebral hemispheric ischemic stroke to reduce the post-stroke deficit.

The aim: Was to evaluate the impact of active rehabilitation treatment in the scheme of comprehensive therapy of patients with cerebral hemispheric ischemic stroke on the dynamics of recovery of cognitive and psychoemotional disorders, as well as to study their correlations. Materials and methods: The study involved 138 patients: 30 apparently healthy individuals (control group, CG, n = 30) without acute cerebrovascular disorders (anamnestic and neuroimaging), of whom 53.33% were men (n = 16) and 46.67% women (n = 14), the average age of patients in the group was 57.9 ± 1.45 years; 108 people diagnosed with cerebral hemispheric ischemic stroke (n = 108), of whom 62.96% were men (n = 68) and 37.04% women (n = 40), the average age of patients in the group was 58.4 ± 0.76 years. The neurocognitive assessment was performed using the international standardized scales: MMSE, MoCa were used to assess the cognitive sphere, and BDI, STAI (STAI SA, STAI TA) were used to assess psychoemotional disorders. Results: Patients in the comprehensive treatment scheme were additionally prescribed and given two courses of rehabilitation treatment using active rehabilitation methods after the first and third examinations, recovery of cognitive and psychoemotional disorders was significantly faster and better than in group 1, where “classical” measures were applied with the predominance of medicinal therapy. Thus, the average score on the MoCa scale during examination on days 3-7 after cerebral hemispheric ischemic stroke in group 1 was 19.71 ± 0.62 points, in group 2 – 19.17 ± 0.54 points, and during evaluation after 6 months in group 2 – 24.72 ± 0.26 points against 22.19 ± 0.41 points (p <0.0001) in group 1. According to the MMSE scale during examination on days 3-7 after cerebral hemispheric ischemic stroke, the average indicator in group 1 was 22.56 ± 0.43 points, in group 2 – 22.47 ± 0.37 points, and when evaluated after 6 months in group 2 – 25.83 ± 0.23 points against 24.35 ± 0.27 points (p = 0.0001) in group 1. Conclusions: The use of methods for active rehabilitation in the treatment of patients in acute and recovery periods of cerebral hemispheric ischemic stroke significantly contributes to the acceleration and enhancement of the recuperation of cognitive and psychoemotional functions after the acute cerebral accident. The obtained results can find practical application in improving the effectiveness of therapeutic and rehabilitation programs in patients with cerebral hemispheric ischemic stroke to reduce their post-stroke deficit.

Cerebral stroke is a «global epidemic», which occupies the leading place in the structure of the causes of disability of the adult population in most countries, having great medical, social, and economic significance. Therefore, this problem is urgent worldwide, being a priority area of the research, which is constantly explored. The earliest possible start of rehabilitation measures improves functional output and reduces the risk of recurrent stroke. Activation and rehabilitation of patients with stroke should begin from the first days of the patient’s stay at the stroke department, immediately after stabilization of the basic vital functions (breath and hemodynamics). The use of international standardized scales is recommended to assess the functional status of the patient, screening, and dynamic diagnosis of motor disorders. The purpose of the study was to evaluate the impact of active rehabilitation treatment in the scheme of comprehensive therapy of patients with cerebral hemispheric ischemic stroke on the dynamics of recovery of motor disorders, and to study their correlations. Materials and methods. The study enrolled 138 patients: 30 healthy individuals (n = 30) and 108 people with cerebral hemispheric ischemic stroke (n = 108), who were divided into two groups: the first group (n = 48), whose treatment generally followed the «classical» measures with the use of medicinal therapy in accordance with the current clinical protocol of medical care for patients with ischemic stroke and the second group (n = 60), in which patients were additionally prescribed and given two courses of rehabilitation using active rehabilitation methods after the first and the third examinations. Results and discussion. The screening was performed using standardized diagnostic scales to determine: stroke severity (National Institutes of Health Stroke Scale), post-stroke functional capacity (Modified Rankin Scale), index of daily activity and self-care ability (Barthel Activities of Daily Living Index), balance impairment (Berg Balance Scale), clinical assessment of spasticity (Modified Ashworth Scale) after acute ischemic cerebrovascular accident. Verification of indicators was performed on days 3-7, day 30, day 90, day 180 after cerebral hemispheric ischemic stroke. In the course of the research, we used modern statistical methods and analyzed the structure of motor disorders before and after treatment, determined the reliability of changes in indicators that demonstrate the dynamics of functional recovery under the influence of active rehabilitation, examined the correlations of motor disorders in the study groups. Conclusion. The obtained results show that the use of active rehabilitation methods in the scheme of comprehensive treatment of patients in acute and recovery periods of cerebral hemispheric ischemic stroke significantly increases the efficiency of recovery of motor functions after the acute cerebral accident

Ischemic stroke is still a very common disease with quite serious consequences. Modern medicine considers in this regard its main task in the curation of such patients, the maximum possible restoration of the functions of the affected brain and the volume of its control over the body. Due to the rapid development of medicine associated with the emergence of innovative technologies in the field of rehabilitation, hardware methods of rehabilitation today have gone far ahead and have in their arsenal a lot of high-tech tools. For this purpose, a search is being made for means of increasing the activity of brain cells located in the affected area. Of particular importance in this regard are the methods of rehabilitation in the early recovery period after ischemic stroke using robotic methods of mechanotherapy, one of which is the use of the Lokomat system. Among them, a prominent place is occupied by the walking training system - Lokomat, consisting of robotic orthoses and a body support device, which are combined with a treadmill. Information about the successful use of Lokomat during the rehabilitation of patients with movement disorders is still scattered, and this required their generalization and understanding. The main advantage of this system is the ability to effectively control and ensure high intensity, repeatability (reproducibility) and purposefulness of the trained movements. The convincing advantages of automated training on the Lokomat system compared to traditional rehabilitation in terms of various clinical indicators in patients with post-stroke hemiparesis have been identified. It was shown that in patients trained on the Lokomat system, a single support on the paretic leg intensified, which contributed to a more symmetrical gait. This system is more than other devices and technologies designed for learning to walk, in line with the modern approach to the restoration of impaired motor functions. The inclusion of training sessions on the Lokomat robotic system in the comprehensive treatment of patients with post-stroke hemiparesis leads to a marked improvement in movement skills. This is associated with a pronounced restructuring against the background of its use of the motor stereotype of walking, which makes it possible to increase the effectiveness of recreational activities in post-stroke patients.

Ischemic stroke triggers an elevation in tonic GABA inhibition that impairs the ability of the brain to form new structural and functional cortical circuits required for recovery. This stroke-induced increase in tonic inhibition is caused by impaired GABA uptake via the glial GABA transporter GAT3, highlighting GAT3 as a novel target in stroke recovery. Using a photothrombotic stroke mouse model, we show that GAT3 protein levels are decreased in peri-infarct tissue from 6 h to 42 days post-stroke. Prior studies have shown that GAT substrates can increase GAT surface expression. Therefore, we aimed to assess whether the GAT3 substrate, L-isoserine, could increase post-stroke functional recovery. L-Isoserine (38 µM or 380 µM) administered directly into the infarct from day 5 to 32 post-stroke, significantly increased motor performance in the grid-walking and cylinder tasks in a concentration-dependent manner, without affecting infarct volumes. Additionally, L-isoserine induced a lasting increase in GAT3 expression in peri-infarct regions accompanied by a small decrease in GFAP expression. This study is the first to show that a GAT3 substrate can increase GAT3 expression and functional recovery after focal ischemic stroke following a delayed long-term treatment. We propose that enhancing GAT3-mediated uptake dampens tonic inhibition and promotes functional recovery after stroke.

Background: Women are known to have worse post-stroke outcomes; however, the underlying mechanisms remain unclear. We evaluated sex-specific clinical and neuroimaging characteristics linked to cerebrovascular brain health in association with functional recovery after acute ischemic stroke (AIS). Methods: We reviewed 316 AIS patients with acute MRI (<48 hours from symptom onset) and modified Rankin scale score (mRS) assessed at 3-6 months post-stroke. Acute infarct volume on diffusion-weighted imaging (DWIv) and white matter hyperintensity volume (WMHv) on FLAIR sequences were determined using a validated semi-automated method. Mean diffusivity (MD) and fractional anisotropy (FA) of normal appearing white matter (NAWM) were derived from the contralesional hemisphere. Wilcoxon rank sum, Spearman correlation, and Fisher’s exact tests were used at p-value <0.05, as appropriate. Results: Women comprised 41.1% of this AIS cohort, and as compared to men, they were older (68 vs. 62.8 years, p = 0.002), had higher prevalence of atrial fibrillation (21.5% vs. 12.4%, p = 0.04), and less tobacco use (21.1% vs. 36.3%, p = 0.03). There was no statistically significant difference between men and women in admission stroke severity, TOAST stroke subtype distribution, DWIv or WMHv. However, women were significantly less likely to have a favorable outcome (mRS <2), as compared to men (53.7% vs. 68.5%, p = 0.01). Both FA (ρ -0.18, p=0.04) and MD (ρ 0.28, p=0.002) values in NAWM correlated with follow-up mRS in women, but only MD (ρ 0.26, p=0.0004) in men. Conclusion: Despite no differences in admission NIHSS, acute infarct size, WMH burden or stroke subtype, women with AIS had significantly worse post-stroke outcomes in our cohort. Our findings suggest that microstructural integrity, as assessed by NAWM diffusivity anisotropy measurements, may represent a neuroimaging correlate of worse outcomes in women. The correlation between markers of white matter microstructural integrity and long-term mRS provides insight into the underlying mechanisms of disease that may influence functional recovery after stroke.

Post-stroke neurological deficits and mortality are often associated with vascular disruption and neuronal apoptosis. Galectin-3 (Gal3) is a potent pro-survival and angiogenic factor. However, little is known about its protective role in the cerebral ischemia/reperfusion (I/R) injury. We have previously shown significant up-regulation of Gal3 in the post-stroke rat brain, and that blocking of Gal3 with neutralizing antibody decreases the cerebral blood vessel density. Our current study demonstrates that intracerebral local delivery of the Gal3 into rat brain at the time of reperfusion exerts neuroprotection. Ischemic lesion volume and neuronal cell death were significantly reduced as compared with the vehicle-treated MCAO rat brains. Gal3 increased vessel density and neuronal survival after I/R in rat brains. Importantly, Gal3-treated groups showed significant improvement in motor and sensory functional recovery. Gal3 increased neuronal cell viability under in vitro oxygen–glucose deprivation conditions in association with increased phosphorylated-Akt, decreased phosphorylated-ERK1/2, and reduced caspase-3 activity. Gene expression analysis showed down regulation of pro-apoptotic and inflammatory genes including Fas-ligand, and upregulation of pro-survival and pro-angiogenic genes including Bcl-2, PECAM, and occludin. These results indicate a key role for Gal3 in neuro-vascular protection and functional recovery following ischemic stroke through modulation of angiogenic and apoptotic pathways.

Ischemic stroke has been becoming one of the leading causes resulting in mortality and adult long-term disability worldwide. Post-stroke pneumonia is a common complication in patients with ischemic stroke and always associated with 1-year mortality. Though ambroxol therapy often serves as a supplementary treatment for post-stroke pneumonia in ischemic stroke patients, its effect on functional recovery and potential mechanism after ischemic stroke remain elusive. In the present study, the results indicated that administration of 70 mg/kg and 100 mg/kg enhanced functional recovery by virtue of decreasing infarct volume. The potential mechanism, to some extent, was due to promoting NSCs differentiation into neurons and interfering NSCs differentiation into astrocytes through increasing GCase expression to activate Wnt/β-catenin signaling pathway in penumbra after ischemic stroke, which advanced basic knowledge of ambroxol in regulating NSCs differentiation and provided a feasible therapy for ischemic stroke treatment, even in other brain disorders in clinic.

Blood-brain barrier (BBB) dysfunction after ischemic stroke exacerbates brain damage by contributing to edema and inflammation. The β1 integrin receptor family may contribute to this dysfunction via alteration of BBB-forming tight junction proteins. We hypothesize that inhibition of the β1 integrin receptor subtype α5β1, which is acutely expressed in infarct and peri-infarct vasculature after experimental stroke, reduces BBB permeability, reduces infarct volume, and improves functional recovery. A randomized and blinded trial was conducted using transient middle cerebral artery occlusion (MCAO) in mice (60 min; n=8) and rats (90 min; n=15) in two independent laboratories. ATN-161 (α5β1 inhibitor; 1 mg/kg) was administered IV immediately upon reperfusion and on post-stroke day 1 and 2. Infarct volume was determined by cresyl violet (mice) and T 2 weighted MRI (rat) at day 3 post MCAO. Steady state contrast enhanced MRI was used to assess BBB breakdown in rats at day 3. ATN-161 resulted in a significant reduction in infarct volume in both mice and rats when measured at post-stroke day 3 (p<0.001). BBB permeability was decreased upon ATN-161 treatment in vivo as determined by reduced IgG and claudin-5 immunostaining in mice and reduced extent of Gadolinium enhanced MRI signal change in rats. Behavioral tests (open field, rotorod, sticky label and 28 point neuroscore), demonstrated significantly improved functional recovery in both mice and rats following treatment with ATN-161. Finally, in vitro studies where stroke was simulated using oxygen and glucose deprivation or TNF-α, ATN-161 (10 μM) treatment demonstrated decreased barrier permeability as measured by trans-endothelial cell electrical resistance, FITC-dextran permeability, and claudin-5 immunocytochemistry. Collectively, our results demonstrate that post-stroke inhibition of α5β1 integrin with the small peptide ATN-161 profoundly reduces infarct volume, improves functional outcome and decreases BBB permeability in both mice and rats using two different ischemic stroke models. Therefore, inhibition of α5β1 by ATN-161 could represent a novel stroke therapeutic target worthy of further investigation.
