Cortical lesions (CLs) are an important component of multiple sclerosis (MS) pathology; they correlate better with physical disability and cognitive impairment than white matter lesions (WMLs). Because remyelination can be extensive in CLs, we quantified remyelination in gray matter (GM) and white matter (WM), addressing oligodendrocyte (OGD) maturation state and clinical relevance of remyelination. Brain tissue samples from 21 chronic MS patients were immunohistochemically stained for myelin proteolipid protein, Olig2, which is strongly expressed in OGD precursor cells (OPCs), but weakly expressed in mature OGDs and other OGD markers...

PURPOSE OF REVIEW: This article argues that the time is approaching for data-driven disease modelling to take centre stage in the study and management of neurodegenerative disease. The snowstorm of data now available to the clinician defies qualitative evaluation; the heterogeneity of data types complicates integration through traditional statistical methods; and the large datasets becoming available remain far from the big-data sizes necessary for fully data-driven machine-learning approaches...

Type I interferons (IFNs), IFN-α and IFN-β, represent the major effector cytokines of the host immune response against viruses and other intracellular pathogens. These cytokines are produced via activation of numerous pattern recognition receptors, including the Toll-like receptor signaling network, retinoic acid-inducible gene-1 (RIG-1), melanoma differentiation-associated protein-5 (MDA-5) and interferon gamma-inducible protein-16 (IFI-16). Whilst the contribution of type I IFNs to peripheral immunity is well documented, they can also be produced by almost every cell in the central nervous system (CNS)...

Objective: Financial capacity is a cognitively-complex activity of daily living that has been shown to decline in a number of neurocognitive disorders. Although it has been well established that cognitive decline is common in multiple sclerosis (MS), little is known about possible financial capacity impairment in people with MS. Thus, the objective of the current study is to investigate financial capacity and its neurocognitive correlates in MS. Methods: Data from 22 people with progressive MS and a healthy comparison group composed of 18 adults were analyzed...

BACKGROUND: Moderate correlation exists between the imaging quantification of brain white matter lesions and cognitive performance in people with multiple sclerosis (MS). This may reflect the greater importance of other features, including subvisible pathology, or methodological limitations of the primary literature. OBJECTIVES: To summarise the cognitive clinico-radiological paradox and explore the potential methodological factors that could influence the assessment of this relationship...

INTRODUCTION: The cerebellum has strong cortical and subcortical connectivity, but is rarely taken into account for clinical diagnosis in many neurodegenerative conditions, particularly in the absence of clinical ataxia. The current meta-analysis aims to assess patterns of cerebellar grey matter atrophy in seven neurodegenerative conditions (Alzheimer's disease (AD), Parkinson's disease (PD) and Huntington's disease (HD), frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS), multiple system atrophy (MSA), progressive supranuclear palsy (MSP))...

Objective: Multiple Sclerosis (MS) is a disease with a detrimental effect on functional status. The present study investigated the effect of a sexual therapy program on the quality of life (QOL) of women with multiple sclerosis. Method: Women with multiple sclerosis and sexual dysfunction (n = 30) were selected, and were randomly assigned into the treatment (n = 15), or the control groups (n = 15). Participants of the treatment group (n = 15) received 12 weekly sessions of sexual therapy. Participants in both groups completed the Female Sexual Function Inventory (FSFI) and the MS Quality of Life- 54 (MSQOL-54) in the onset of the program and at the end of the program...

BACKGROUND AND PURPOSE: Gadolinium-based contrast agents have been associated with lasting high T1-weighted signal intensity in the dentate nucleus and globus pallidus, with histopathologically confirmed gadolinium retention. We aimed to longitudinally investigate the relationship of multiple gadolinium-based contrast agent administrations to the Signal Intensity Index in the dentate nucleus and globus pallidus and any associations with cognitive function in multiple sclerosis. MATERIALS AND METHODS: The Signal Intensity Index in the dentate nucleus and globus pallidus was retrospectively evaluated on T1-weighted MR imaging in an 18-year longitudinal cohort study of 23 patients with MS receiving multiple gadolinium-based contrast agent administrations and 23 healthy age- and sex-matched controls...

Cognitive impairment affects more than half of all individuals living with multiple sclerosis (MS). We hypothesized that training at home with an adaptive online cognitive training program would have greater cognitive benefit than ordinary computer games in cognitively-impaired adults with MS. This was a double-blind, randomized, active-placebo-controlled trial. Participants with MS were recruited through Stony Brook Medicine and randomly assigned to either the adaptive cognitive remediation (ACR) program or active control of ordinary computer games for 60 hours over 12 weeks...

BACKGROUND: Fatigue is one of the most prevalent and burdensome symptoms for patients with inflammatory bowel disease (IBD). Although fatigue increases during periods of inflammation, for some patients it persists when disease is in remission. Compared to other long-term conditions where fatigue has been extensively researched, optimal management of fatigue in patients with IBD is unknown and fatigue has rarely been the primary outcome in intervention studies. To date, interventions for the management of IBD-fatigue are sparse, have short-term effects and have not been implemented within the existing health system...

Abnormal corticostriatal resting-state functional connectivity (rsFC) has been implicated in the neuropathology of multiple sclerosis. The striatum, a component of the basal ganglia, is involved in diverse functions including movement, cognition, emotion, and limbic information processing. However, the brain circuits of the striatal subregions contributing to the changes in rsFC in relapsing-remitting multiple sclerosis (RRMS) patients remain unknown. We used six subdivisions of the striatum in each hemisphere as seeds to investigate the rsFC of striatal subregions between RRMS patients and matched healthy controls (HCs)...

OBJECTIVE: To investigate default-mode network (DMN) and frontoparietal network (FPN) dysfunction in cognitively impaired (CI) patients with multiple sclerosis (MS) because these networks strongly relate to cognition and contain most of the hubs of the brain. METHODS: Resting-state fMRI and neuropsychological assessments were performed in 322 patients with MS and 96 healthy controls (HCs). Patients with MS were classified as CI (z score < -2.0 on at least 2 tests; n = 87), mildly cognitively impaired (z score < -1...

Disease activity in multiple sclerosis (MS) has classically been defined by the occurrence of new neurological symptoms and the rate of relapses. Definition of disease activity has become more refined with the use of clinical markers, evaluating ambulation, dexterity, and cognition. Magnetic resonance imaging (MRI) has become an important tool in the investigation of disease activity. Number of lesions as well as brain atrophy have been used as surrogate outcome markers in several clinical trials, for which a reduction in these measures is appreciated in most treatment studies...

BACKGROUND: Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system, which often causes progressive neurological disability. In addition to motor and sensory dysfunction, cognitive decline and fatigue are frequent manifestations of the disease. Fatigue is probably the most common symptom, with up to 90% of MS individuals reporting fatigue at some point. Cognitive impairment affects about 50% of patients and may be present at all MS stages. The aim of this observational study was to evaluate changes in cognition, fatigue, and disability status in 300 relapsing-remitting MS (RRMS) patients, treated with subcutaneous (sc) interferon (IFN) β-1a over 2 years...
