Cognitive impairment (CI) affects 40-65% of patients with multiple sclerosis (MS). CI can have a negative impact on a patient's everyday activities, such as engaging in conversations. Speech production planning ability is crucial for successful verbal interactions and thus for preserving social and occupational skills. This study investigates the effect of cognitive-linguistic demand and CI on speech production planning in MS, as reflected in speech prosody. A secondary aim is to explore the clinical potential of prosodic features for the prediction of an individual's cognitive status in MS...

BACKGROUND AND PURPOSE: Many patients with multiple sclerosis (MS) report a worsening of symptoms due to high ambient temperatures, but objective data about this association are rare and contradictory. The aim of this study was to investigate the influence of ambient temperature on standard clinical tests. METHODS: We extracted the Symbol Digit Modality Test, Nine Hole Peg Test, Timed 25 Foot Walk (T25FW), Timed Tandem Walk, Expanded Disability Status Scale (EDSS) and quality-of-life items on cognition, fatigue and depression from our clinical database and matched them to historical temperatures...

PURPOSE: To investigate how psychotherapists experience using individual, face-to-face cognitive behavioural therapy (CBT) aimed at alleviating depressive symptoms in persons with multiple sclerosis (MS). METHOD: Semi-structured interviews with three psychotherapists were conducted after CBT with 12 participants with MS, and analysed using qualitative content analysis. RESULTS: Two main themes emerged: Trusting their expertise as psychotherapists whilst lacking MS-specific knowledge, and The process of exploring the participants' readiness for CBT with modifications of content and delivery...

Driving errors that predict on-road outcomes for persons with multiple sclerosis (PwMS) are not well studied. The objective of this study was to determine whether adjustment-to-stimuli and gap acceptance errors significantly predict passing/failing a standardized on-road assessment of PwMS. Thirty-seven participants completed visual ability and visual attention assessments, and participated in an on-road assessment, where seven types of driving errors and pass/fail outcomes were determined. Adjustment-to-stimuli (No...

BACKGROUND: Damage of different brain structures has been related to fatigue. Alternatively, functional alterations of central nervous system (CNS) cells by the inflammatory milieu within the CNS may be responsible for the development of fatigue. AIM: To investigate the effect of structural brain damage and inflammatory cerebrospinal fluid (CSF) changes on fatigue in multiple sclerosis (MS). METHODS: We determined the association of different clinical, CSF and magnetic resonance imaging (MRI) parameters with prevalence and severity of fatigue, as measured by the Fatigue Scale for Motor and Cognitive Functions in 68 early MS patients (discovery cohort)...

BACKGROUND: Reduced information-processing speed (IPS) is a primary cognitive deficit of multiple sclerosis (MS) patients. The neural efficiency hypothesis describes an inverse relationship between cognitive performance in a task and the amount of cognitive resources devoted to it. Previous studies have shown that the neural efficiency hypothesis provides an appropriate framework to explore cognitive dysfunction in neurological patients. OBJECTIVE: The aim of this study was to explore the neural efficiency hypothesis regarding IPS capabilities in cognitively preserved MS patients...

BACKGROUND: Commonalities in the core symptoms of fatigue and cognitive dysfunction experienced by chronic fatigue syndrome (CFS, also known as ME) and multiple sclerosis (MS) patients have been described. Many CFS and MS patients also experience chronic pain, which has been attributed to central sensitization in both groups of patients. However, the characteristics of pain in CFS and MS patients have not been compared. OBJECTIVES: To compare experimental pain measurements in patients with CFS or MS and healthy controls...

The Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) was developed to provide valid assessment of cognitive impairment in multiple sclerosis (MS). The relationship between clinical and social variables and cognitive disorders has been extensively studied, but primarily in developed countries with a focus on other cognitive measures or batteries. The objectives of this study were to analyze the relationship between the BICAMS data and key clinical and sociodemographic variables in the Argentine MS population...

While some autoimmune disorders remain extremely rare, others largely predominate the epidemiology of human autoimmunity. Notably, these include psoriasis, diabetes, vitiligo, thyroiditis, rheumatoid arthritis and multiple sclerosis. Thus, despite the quasi-infinite number of "self" antigens that could theoretically trigger autoimmune responses, only a limited set of antigens, referred here as superautoantigens, induce pathogenic adaptive responses. Several lines of evidence reviewed in this paper indicate that, irrespective of the targeted organ (e...

BACKGROUND: Fatigue is a common symptom in multiple sclerosis (MS) and often restricts societal participation. Cognitive behavioral therapy (CBT) may alleviate MS-related fatigue, but evidence in literature is inconclusive. OBJECTIVE: To evaluate the effectiveness of CBT to improve MS-related fatigue and participation. METHODS: In a multi-center, assessor-masked, randomized controlled trial, participants with severe MS-related fatigue were assigned to CBT or control treatment...

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...

REVIEW
Thomas Blank, Marco Prinz
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...

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...
