Objective: Amyotrophic lateral sclerosis is a neurodegenerative disease with high rates of disability and mortality. Non-invasive ventilation (NIV) is an effective method of treating patients, increasing life expectancy, but currently, predictors available to determine the best outcome of therapy in this category of patients are unknown. This systematic review aimed to determine the impact of prognostic factors on benefits from NIV application compared with non-NIV tools of treatment (invasive ventilation and standard care) in case of survival of ALS patients.

Background: Yoga originated in the territory of modern India more than 3,000 years ago uses techniques for working with the musculoskeletal system, cardiorespiratory system, and attention. Currently, the effectiveness and safety of yoga in patients with various neurological disorders, including multiple sclerosis (MS), is of interest to many scientists and clinicians.

Purpose: The main aim of this study is to examine the effect of yoga on symptoms and quality of life in patients with MS vs physical therapy (exercise therapy) and no exercise.

Objective: The aim of this study is to elaborate a valid and reliable Russian version of the ALSFRS-R.

Methods: Russian adaptation of the ALSFRS-R was applied twice in 50 ALS patients followed by the test-retest analysis with a 7-day interval between applications and internal consistency analysis.

Results: Test-retest analysis showed very strong correlation for all of the ALSFRS-R variables.

Respiratory failure, malnutrition, aspiration pneumonia, and dehydration are the precursors to mortality in ALS. Loss of natural communication is considered one of the worst aspects of ALS. This first study to test the feasibility of a music therapy protocol for bulbar and respiratory rehabilitation in ALS employs a mixed-methods case study series design with repeated measures.

Pediatric investigation plans (PIPs) describe how adult drugs can be studied in children. In 2015, PIPs for Amyotrophic Lateral Sclerosis (ALS) became mandatory for European marketing-authorization of adult treatments, unless a waiver is granted by the European Medicines Agency (EMA). To assess the feasibility of clinical studies on the effect of therapy in children (<18 years) with ALS in Europe.

Article Synopsis
  • ALS is a life-threatening neurodegenerative disease affecting 1 in 350 individuals, and there is a significant need for treatments that modify the disease's progression.
  • A large genome-wide association study (GWAS) identified 15 genetic risk loci associated with ALS by analyzing data from nearly 30,000 ALS patients compared to over 122,000 controls.
  • The study highlights genetic connections to other neurodegenerative traits and concludes that high cholesterol levels may play a causal role in ALS, emphasizing disturbances in cellular transport and autophagy as key factors in the disease’s development in glutamatergic neurons.

Background And Purpose: A few groups have suggested that activated cytokines and nitrosative stress are closely involved in the pathogenesis of different demyelinating disorders induced by the neuroinflammatory destruction of neurons. The purpose of this study was to elucidate the associations of cytokines and S-nitrosothiols (RSNO) with the severity of neurodegeneration during relapse in demyelinating disorders of the central nervous system.

Methods: We measured levels of interleukin-6 (IL-6), erythropoietin, RSNO, and phosphorylated neurofilament heavy chain (pNfh) in cerebrospinal fluid (CSF) samples obtained from patients with different demyelinating disorders: multiple sclerosis (MS, n=52), acute disseminated encephalomyelitis (ADEM, n=9), and neuromyelitis optica spectrum disorders (NMOSD) with aquaporin-4 immunoglobulin G (AQP4-IgG, n=12).

Multiple sclerosis is a chronic demyelinating disorder of the central nervous system. There are many cases of multiple sclerosis - like syndrome and demyelinating disorders in systemic lupus erythematosus, Sjogren disease, Behcet disease and other autoimmune conditions. Coexistence of ankylosing spondylitis and multiple sclerosis usually is rare but in this article we report 4 Russian patients with concomitant multiple sclerosis and ankylosing spondylitis diseases.

Multiple sclerosis (MS) is an immune-mediated disorder associated with inflammation, demyelination and axonal damage. In search of potential biomarkers of spinal cord lesions in MS related to nitric oxide metabolites, we measured total nitrite and nitrate levels, and protein-bound nitrotyrosine and S-nitrosothiol concentrations in the serum of MS patients at different stages of the disease. Sixty-eight patients and 36 healthy volunteers were included in the study.
