Using information from the MSBase registry, the GLIMPSE (Generating Learnings In MultiPle SclErosis) study looked at real-life outcomes in 3475 people living with MS who were treated with cladribine tablets (Mavenclad® ) compared with other oral treatments...

Aim: This study investigates perspectives on computer-based assessments among elderly individuals with Parkinson's disease (PD) in India for more efficient usability of digital assessments for this population. Materials & methods: Content analysis was conducted on 30 participants diagnosed with PD, who were interviewed for their preferences and perspectives on integrating technology in healthcare assessments. Results: Elderly individuals with PD in India favored paper-pencil assessments over computer-based alternatives due to limited technological familiarity, resistance to change, lack of trust in healthcare technology and PD related motor challenges...

Aim: This study aimed to explore the impact of caring for an individual with neurogenic orthostatic hypotension (nOH). Methods: Informal caregivers of individuals with nOH and either Parkinson's disease, multiple system atrophy, pure autonomic failure or dementia with Lewy bodies completed semi-structured interviews. Data were analyzed using thematic analysis; the identified concepts were used to develop a conceptual model. Results: Twenty informal caregivers were interviewed. Analysis identified several areas of caregiver impact due to nOH including impact on their time, particularly a need to supervise the patient to prevent falls as well as a lack of freedom and negative physical, work and social impacts...

Levodopa is the most effective agent for treating the symptoms of Parkinson's disease (PD). However, levodopa-induced dyskinesia remains a significant complication that manifests after few years of treatment, for which therapeutic options remain limited. Several agonists of the serotonin type 1A (5-HT1A ) receptor with varying levels of efficacy and interaction at other sites, have been tested in the clinic. Clinical trials testing 5-HT1A agonists have yielded inconsistent results in alleviating dyskinesia, especially that the antidyskinetic benefit observed was often accompanied by an adverse effect on motor function...

Aim: The goal of this study was to analyze the effects of external rhythmic auditory stimulation (RAS) on gait variability in older adults and people with Parkinson's disease (PD). Methods: Academic databases searched included PubMed, Web of Science, PEDro and Cochrane, from inception to September 2021. Eligible articles scored a minimum of 4 on the PEDro scale. Results: Twenty-three papers were included. People with PD show varied responses in gait variability to RAS during cued walking trials. Healthy older adults tended to increase variability during cued trials...

Introduction: Living with a neuromuscular disease often leads to a need for specialized rehabilitation due to the complexity and progression of the diseases. Aim: To investigate cross-sectoral collaboration on rehabilitation for patients with neuromuscular diseases among hospital professionals to inform future targeted rehabilitation services. Patients & methods: The design was qualitative using the interpretive description methodology and the theoretical lens of symbolic interactionism. Ethnographic fieldwork was conducted, and 50 hospital professionals included, 19 of whom were interviewed...

WHAT IS THIS SUMMARY ABOUT?: This plain language summary of an article published in Molecular Psychiatry , reviews the evidence supporting the role of the amyloid-β (Aβ) pathway and its dysregulation in Alzheimer's disease (AD), and highlights the rationale for drugs targeting the Aβ pathway in the early stages of the disease. WHY IS THIS IMPORTANT?: Aβ is a protein fragment (or peptide) that exists in several forms distinguished by their size, shape/structure, degree of solubility and disease relevance...

Aim: To quantify and provide an overview on the scientific productivity made by Moroccan academics in the research on Parkinson's disease (PD) and parkinsonism. Materials & methods: Scientific articles, in either English or French, were gathered from published literature in three recognized databases: PubMed, ScienceDirect and Scopus. Results: We identified 95 published papers from which 39 articles have been extracted after removing inadequate publications and duplications between databases. All articles were published between 2006 and 2021...

Introduction: Patient-reported outcomes (PROs) are valuable measures for routine clinical care of people with multiple sclerosis (pwMS). Materials: 646 pwMS treated with interferon-β-1a (IFN-β-1a) were retrospectively included from the New York State Multiple Sclerosis Consortium. Clinical and PRO data at enrollment and 3 year follow-up were collected. PwMS with stable disease and disability worsening were matched (1:1) based on age, Expanded Disability Status Scale (EDSS) scores and disease duration...

WHAT IS THIS SUMMARY ABOUT?: This is a summary of an article originally published in the Multiple Sclerosis Journal . Cladribine tablets (MAVENCLAD® ) are an oral (taken by mouth) medication, approved for the treatment of people with relapsing forms of multiple sclerosis (MS, with episodes of new or worsening symptoms). They are administered for a maximum of 10 days per year, over a period of 2 years. Cladribine tablets work by temporarily reducing the number of lymphocytes, which are immune cells that help to fight off infections...

Aim: This study explores the burden of caring for an individual with neurogenic orthostatic hypotension (nOH) and an underlying neurodegenerative disease (Parkinson's disease, multiple system atrophy, pure autonomic failure or dementia with Lewy bodies). Materials & methods: A survey including several validated instruments was conducted with informal caregivers of individuals with Parkinson's disease, multiple system atrophy, pure autonomic failure or dementia with Lewy bodies. Results: Caregivers of patients with nOH (n = 60) reported greater burden across all outcomes compared with those without nOH (n = 60)...

Aim: To investigate whether the estimation of cerebrospinal fluid (CSF) and brain YKL-40 levels may be used as an efficient biomarker for Parkinson's disease (PD). Methods: Lipopolysaccharides (LPS) was injected into the right substantia nigra pars compacta (SNpc). Rats were divided into: control group, early LPS-induced PD group (14 days), and advanced LPS-induced PD group (28 days). YKL-40 and other related factors were detected in CSF and brain tissue. Results: Increased expression of YKL-40 was observed in brain tissue and CSF of PD-induced rats associated with triggered inflammatory cytokine release...

Aim: Evaluate timing of motor improvement with carbidopa/levodopa (CD/LD) and apomorphine sublingual film (SL-APO) in patients with Parkinson's disease and OFF episodes. Methods: A post hoc pooled analysis from two studies assessed Movement Disorder Society Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS-III) scores and investigator-rated FULL ON. Results: At 15 and 30 min following the prescribed first daily CD/LD dose, mean improvements in MDS-UPDRS-III scores were -6.7 and -16.3, respectively, and FULL ON was achieved by 6...

Aim: To evaluate glatiramer acetate (GA) or IFN-β effects on quality of life (QoL) in people with relapsing/remitting multiple sclerosis (PwRRMS) in Greece. Methods: A prospective, practice-based study. QoL/function/symptoms were assessed by seven questionnaires/scales. Results: Significant increases in Short Form-36 (SF-36) health survey scores occurred with GA in four of the eight domains and three of the eight domains at 6 and 12 months, respectively, versus baseline. Similar and significant SF-36 score improvements occurred with GA in treatment-naive PwRRMS...
