We determined the level of brain neurotrophic factor BDNF in plasma of adolescents aged 12-17 with syncopal conditions. Lower BDNF levels in plasma were found in a large number of adolescents examined. Taking into account the significant role of BDNF in the modulation of neuroplastic processes, the revealed decrease in its level can probably be regarded as a metabolic marker of the risk of neurodegenerative processes appearance and presence in brain tissue of adolescents with recurrent syncope. This assumption can be confirmed by further studies. Conclusions: syncopal conditions in adolescents are associated with a lower content of brain neurotrophic factor BDNF. In adolescents with syncopal conditions, there are more individuals with slightly or significantly lower BDNF compared to the group without syncope

The prevalence of nucleotide sequence variants of genes collagen COL1A1 rs1800012 IVS1 c.2046 G> T, and receptors of calcitonin CALCR rs1801197 c.1377 T> C and the intracellular vitamin D VDR rs731236 c.1056 T> C in healthy teenagers of the Primorsky Territory was studied in correlation with physiological parameters of the musculoskeletal system status. Genetic testing made it possible to identify the prevalence of “unfavorable” alleles and their combinations in the studied genes, regulating calcium metabolism in teenagers, and to determine the relationship between genotypes and the presence of fractures and impaired posture, that allowed distinguishing a group of subjects with a high risk of developing MSS diseases

A literature review of the disease spinocerebellar ataxia type 17 (SCA 17) was carried out. The clinical observation of SCA 17 was presented considering the absence of inverse correlation between a degree of expansion and age of manifestation of SCA 17 symptoms, as well as direct relationship between the degree of expansion of repeats and the severity of clinical manifestations. We also revealed differences in the clinical picture of SCA 17 in this case and SCA 1, which is widespread in Yakutia

In the article the literature data on MSA, the clinical features are studied and modern diagnostic criteria for this disease are provided. We introduce our own observations of the patients with various forms of MSA who underwent inpatient treatment at the Center for Neurodegenerative Diseases of the Yakutsk Scientific Center for Complex Medical Problems in 2019-2020. These clinical cases have been studied with the aim to draw attention of general practitioners and neurologists to the disease onset among elderly patients and to the syndrome of autonomic insufficiency, which may be the initial manifestation of MSA, since this rare disease has a rapidly progressive course and leads to mortaltiy. In turn, the early diagnosis of the disease contributes to timely correction of autonomic and motor disorders and ultimately increases quality and lifetime

This article considers the use of microRNAs as a possible biomarker of epilepsy. The presented studies have shown that microRNAs can be involved in the process of epileptogenesis by regulating the inflammatory response, apoptosis of neurons, and transcription factors involved in cell differentiation. Biological fluids (blood and CSF) of patients with epilepsy showed differences in the number of circulating microRNAs, which may allow further use of microRNAs as a diagnostic biomarker. Recent discoveries providethe sufficient source of new microRNA targets, but there are still significant problems of studying their role in pathogenesis and the possibility of their application in clinical practice

Cerebral amyloid angiopathy (CAA) is a disease of the small cerebral vessels and it mostly affects older people. CAA is characterized by progressive deposition of amyloid-beta in small arteries and arteries of medium caliber, as well as in the capillaries. Sporadic amyloid angiopathy is a cause of recurrent cerebral hemorrhage and cognitive impairment in the elderly. The latest scientific researches and a case report of a patient who suffered from cerebral amyloid angiopathy were used in order to prepare this article. The diagnosis and treatment of CAA are considered

The article presents the results of a clinical and genetic study of a Yakut family with hereditary spastic paraplegia (HSP). Patients with clinically diagnosed HSP and healthy family members were studied. The disease is clinically characterized as a progressive spastic paraplegia of the lower extremities concomitant peripheral neuropathy in advanced case. The methods of exome sequencing of the entire genome, molecular modeling of dynamin-2 and experimental reproduction of key elements of the HSP pathogenesis have been applied. Genetic analysis revealed a novel missense c.2155C> T, p.R719W mutation in the highly conserved GTP-effector domain of the dynamin-2 gene (DNM2). In experiments on HeLa cells, it was shown that mutant dynamin-2 affected endocytosis process. In-silico modeling determined that the identified mutation is located in the DNM2 bundle-signaling element and potentially disrupts the assembly and functional properties of the protein. Testing of this mutation in other Yakut families with HSP showed a negative result, which once again confirms the genetic heterogeneity of this pathology

The purpose of research was comparison of parameters of the contents of hormones in blood of boys with different forms of epilepsy. Significant differences in contents of hormones were revealed in group of children with idiopathic and symptomatic generalized epilepsies. Findings of investigation testify that the most expressed changes in contents of hormones in blood were revealed in boys of all ages with symptomatic temporal form of epilepsy. Obtained data confirm necessity of research and evaluation of hormonal status at children with epilepsy for prevention and correction of possible endocrine disturbances

The purpose of research were the substantiation of the diagnosis and correction or change of treatment of children with the epileptic and not epileptic paroxysms, directed in St.-PbSPMA for refinement of the diagnosis, the form of an epilepsy and selection of adequate treatment. As a result of complex diagnostic study of sick children with conducting video-EEG of monitoring it is established, that more than a half of children had the diagnosis epileptic paroxysms. Correction of treatment made after refinement of the diagnosis. As a result on clinical data efficacy of treatment of children with an epilepsy has increased. We were noted martempering of cognitive functions at children with not epileptic paroxysms

The results of ischemic stroke thrombolytic therapy in the primary vascular department in Yakutia in 2019-2020 were studied. The proportion of ischemic stroke patients who received intravenous thrombolytic therapy (IVT) was 6.3% (n = 9). We investigated groups of patients with and without IVT (n = 9 and n = 62, respectively), comparable in age and sex. One third of patients had the cardioembolic ischemic stroke. 80.2% of intravenous thrombolytic therapy’s contraindications were associated with hospitalization beyond the 4.5-hour “therapeutic window”. There were no fatal outcome or symptomatic hemorrhagic complications in the IVT group. At the end of the acute period, the neurological status according to the NIHSS scale was comparable (p = 0.488), as was the degree of functional independence according to the Rankin Scale (p = 0.819) between groups with and without intravenous thrombolytic therapy. In the Yakutia, taking into account the low population density, large territory, complex transport scheme and peculiarities of climatic conditions, it is advisable to use the possibilities of telemedicine for conducting thrombolytic therapy of ischemic stroke. In the republic, for the increasing the account of intravenous thrombolytic therapy it is necessary to introduct the telethrombolysis method in regional hospitals that have computed tomography devices, as well as in primary vascular departments for the providing teleconsulting with the neuroimaging analysis in difficult clinical cases. The creation of a telethrombolysis network will increase the availability of modern methods of specialized medical care for patients with acute cerebrovascular accidents in areas with vast territories and low population density
