The clinical significance of Virchow Robin spaces (VRS) in inflammatory brain disorders, especially in multiple sclerosis (MS), is still undefined. We analysed enlarged VRS (eVRS) by means of phase sensitive inversion recovery (PSIR) MRI sequence and investigated their association with inflammation or brain atrophy, and to clinical or physical disability. Forty-three MS patients (21 clinically isolated syndrome suggestive of MS [CIS], 15 RRMS, 7 progressive [PMS]) and 10 healthy controls (HC) were studied. 3DT1, 3DFLAIR and 2DPSIR images were obtained with a 3T MRI scanner...

Accumulating data suggests that miRNAs might play a major role in neuroinflammatory processes. Therefore, our study aimed to first estimate the levels of miR-155, miR-326, and miR-301a in serum of RR-MS patients in the remission phase and then compare the levels of the examined miRNAs at different times after relapse. In this study, 36 RR-MS patients in the remission phase took part. We analyzed two subgroups of RR-MS: one, 1 to 2 months after completing steroid treatment during relapse (post-acute; n = 13) and the other, over 2 years without any relapse (stable; n = 23)...

Treatment options for progressive multiple sclerosis remain the main unmet need of the field. As the understanding of multiple sclerosis (MS) pathogenesis improves, new pathways and molecules will be tested for potential reparative, remyelinating, or neuroprotective effects. The clinical outcomes used will determine successful demonstration of beneficial treatment effects to regulatory agencies, clinicians, and persons with MS. This review focuses on clinical outcome measures including the Expanded Disability Status Scale, Multiple Sclerosis Functional Composite, and novel composite measures of disability...

OBJECTIVES: Amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease, restricts patients' communication capacity a few years after onset. A proof-of-concept of brain-computer interface (BCI) has shown promise in ALS and "locked-in" patients, mostly in pre-clinical studies or with only a few patients, but performance was estimated not high enough to support adoption by people with physical limitation of speech. Here, we evaluated a visual BCI device in a clinical study to determine whether disabled people with multiple deficiencies related to ALS would be able to use BCI to communicate in a daily environment...

OBJECTIVE: Quantitative and semi-quantitative MRI (qMRI) metrics provide complementary specificity and differential sensitivity to pathological brain changes compatible with brain inflammation, degeneration, and repair. Moreover, advanced magnetic resonance imaging (MRI) metrics with overlapping elements amplify the true tissue-related information and limit measurement noise. In this work, we combined multiple advanced MRI parameters to assess focal and diffuse brain changes over 2 years in a group of early-stage relapsing-remitting MS patients...

BACKGROUND: Cognitive Behavioural Therapy (CBT) reduces distress in multiple sclerosis, and helps manage adjustment, but cost-effectiveness evidence is lacking. METHODS: An economic evaluation was conducted within a multi-centre trial. 94 patients were randomised to either eight sessions of nurse-led CBT or supportive listening (SL). Costs were calculated from the health, social and indirect care perspectives, and combined with additional quality-adjusted life years (QALY) or improvement on the GHQ-12 score, to explore cost-effectiveness at 12 months...

Cognitive impairment is a significant clinical problem both in multiple sclerosis (MS) and systemic lupus erythematosus (SLE) patients. In MS cognitive dysfunction has been associated with brain atrophy and total demyelinating lesion volume. In SLE cognitive impairment is much less understood, and its link to structural brain damage remains to be established. The aim of this study was to identify the relationship between subcortical gray matter volume and cognitive impairment in MS and SLE. We recruited 37 MS and 38 SLE patients matched by age, disease duration and educational level...

OBJECTIVE: Cognitive impairment (CI) is common in multiple sclerosis (MS). An international consensus committee developed the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) to screen for CI commonly seen in MS. BICAMS cut scores would allow clinicians to, efficiently and effectively, identify patients with possible CI and could aid in clinical decision-making. The aim of this study was to establish cut scores for the neuropsychological tests of the BICAMS. METHODS: This study utilized data collected from MS Centers in the United States...

BACKGROUND: Careful consideration of intervention fidelity is critical to establishing the validity and reliability of research findings, yet such reports are often lacking in the research literature. It is imperative that intervention fidelity be methodically evaluated and reported to promote the translation of effective interventions into sound evidence-based practice. PURPOSE: The purpose of this article is to explore strategies used to promote intervention fidelity, incorporating examples from a multisite clinical trial, that illustrate the National Institutes of Health Behavior Change Consortium's 5 domains for recommended treatment practices: (1) study design, (2) facilitator training, (3) intervention delivery, (4) intervention receipt, and (5) intervention enactment...

Caffeine is one of the most consumed stimulant of the central nervous system. Similar to those of other stimulants, its effects are to improve brain activity and stimulate cognition learning and memory. Caffeine affects the brain by acting mainly as a non-selective blocker of the adenosine receptors (A1, A2A, A2B, and A3). The purpose of this review article is to provide an overview on the neurobiochemical impact of caffeine, focusing on the ability of the drug to effectively counteract several neurodegenerative disorders such as Alzheimer's, Parkinson's, Huntington's diseases, Multiple sclerosis and Amyotrophic lateral sclerosis and Epilepsy...

Patients with multiple sclerosis (MS) often suffer from psychological distress and cognitive dysfunctioning. These factors negatively impact the health-related quality of life. Only recently behavioral therapeutic approaches are being used to treat psychological distress in MS. The aim of the present pilot study was not only to investigate the effectiveness of mindfulness-based stress reduction (MBSR) on psychological distress but also to explore whether it can improve cognitive functioning among patients with MS...

BACKGROUND: Multiple sclerosis (MS) is commonly associated with psychological complications. Previous research by Hayter and colleagues (2016) found that in patients with MS, health anxiety (HA) can account for part of the variance in quality of life (QoL) independent of physical and cognitive impairment caused by the disease. MS patients with HA perceived their intact physical and cognitive performance as impaired relative to those without HA and attributed the impairment to MS. These misperceptions might be useful targets in the treatment of HA in MS using cognitive behaviour therapy (CBT)...

OBJECTIVE: Functional connectivity is known to increase as well as decrease throughout the brain in multiple sclerosis (MS), which could represent different stages of the disease. In addition, functional connectivity changes could follow the atrophy pattern observed with disease progression, that is, moving from the deep grey matter towards the cortex. This study investigated when and where connectivity changes develop and explored their clinical and cognitive relevance across different MS stages...

REVIEW
Sandra Vanotti, Fernando J Caceres
Cognitive and neuropsychiatric disorders in patients with multiple sclerosis have been extensively documented. The focus of this review will be on cognitive and neuropsychiatric disorders in multiple sclerosis patients from Latin America, in the context of international literature. Multicentre studies carried out in Latin America have shown that 43% of the patients have cognitive impairment and 34.5% in early stages of the disease, 29% depression and 20.9% neuropsychiatric disorders. The profile of cognitive impairment corresponds to alterations in visual and verbal memory, in attention, in information processing speed and in verbal fluency...
