We examined relationships between the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) General Ability Index (GAI) and Cognitive Proficiency Index (CPI) in two clinical samples. The mean pattern produced by 42 individuals with multiple sclerosis (MS) and 47 with traumatic brain injury (TBI) was the same, GAI > CPI. This pattern occurred in 61.9% and 78.7% of the protocols of patients with MS or TBI, respectively. The MS sample earned a significantly larger CPI mean than did patients with TBI...

Sleep disturbances are common in multiple sclerosis (MS), but its impact on cognition and functional connectivity (FC) of the hippocampus and thalamus is unknown. Therefore, we investigated the relationship between sleep disturbances, cognitive functioning and resting-state (RS) FC of the hippocampus and thalamus in MS. 71 MS patients and 40 healthy controls underwent neuropsychological testing and filled out self-report questionnaires (anxiety, depression, fatigue, and subjective cognitive problems). Sleep disturbances were assed with the five-item version of the Athens Insomnia Scale...

Mobility and cognitive impairments are common in persons with multiple sclerosis (MS), and are expected to worsen with increasing age. However, no studies, to date, in part due to limitations of conventional neuroimaging methods, have examined changes in brain activation patterns during active locomotion in older patients with MS. This study used functional Near Infrared Spectroscopy (fNIRS) to evaluate real-time neural activation differences in the pre-frontal cortex (PFC) between middle-aged to older adults with MS and healthy controls during single (Normal Walk; NW) and dual-task (Walking While Talking; WWT) locomotion tasks...

BACKGROUND: Recent studies suggest that cortical lesions in multiple sclerosis (MS) substantially contribute to clinical disease severity. The present study aimed at investigating clinical, neuroanatomical, and cognitive correlates of these cortical lesions with a novel approach, i.e. by comparing two samples of relapsing-remitting multiple sclerosis (RRMS) patients, one group with and the other without cortical lesions. METHODS: High-resolution structural MRI was acquired from 42 RRMS patients and 43 controls (HC)...

Multiple sclerosis (MS) and working status have recently arisen great interest. Fatigue, physical disability, cognition, and psychological disturbances have been linked to unemployment, as well to accidents during daily activities. The aim of our study was to determine frequency of different types of accidents at workplace (AWE) and possible clinical differences among employed (MSe) and unemployed (MSu) MS patients. Sixty MS patients (31 employed, 29 unemployed) and twenty healthy control subjects were recruited...

OBJECTIVE: To investigate the role of cerebellar sub-regions on motor and cognitive performance in multiple sclerosis (MS) patients. METHODS: Whole and sub-regional cerebellar volumes, brain volumes, T2 hyperintense lesion volumes (LV), and motor performance scores were obtained from 95 relapse-onset MS patients and 32 healthy controls (HC). MS patients also underwent an evaluation of working memory and processing speed functions. Cerebellar anterior and posterior lobes were segmented using the Spatially Unbiased Infratentorial Toolbox (SUIT) from Statistical Parametric Mapping (SPM12)...

Multiple sclerosis (MS) is a socially significant immune-mediated disease, characterized by demyelination, axonal transection and oligodendropathy in the central nervous system. Inflammatory demyelination and neurodegeneration lead to brain atrophy and cognitive deficit in up to 75% of the patients. Cognitive dysfunctions impact significantly patients' quality of life, independently from the course and phase of the disease. The relationship between pathological brain findings and cognitive impairment is a subject of intensive research...

BACKGROUND: Slowness of information processing has been suggested as a fundamental factor modulating cognitive impairment in multiple sclerosis (MS). However, the contribution of depressive symptoms (DS) to slowness remains unclear. One of the most accepted hypotheses on the impact of depression on the general population suggests that depression interferes only with tasks requiring high cognitive demands. However, no studies have investigated if the same pattern occurs in MS. OBJECTIVE: The aim of this study was to determine the profile of the contribution of DS to slowness...

BACKGROUND: Clinical studies have suggested beneficial effects of exercise on cognitive function in ageing adults and neurodegenerative diseases such as dementia. Recent work indicates the same for progressive multiple sclerosis (MS), an inflammatory and degenerative disease of the central nervous system (CNS). The biological pathways associated with these effects are however not well understood. OBJECTIVE: In this randomized controlled study, we explored serum levels of the myokine Irisin, the neurotrophin brain-derived neurotrophic factor (BDNF) and Interleukin-6 (IL-6) during acute endurance exercise and over the course of a 9-weeks endurance exercise training period in n=42 patients with progressive MS...

AIMS: Interpreting change scores is challenging when patients' global rating of change (GRC) scores contradict their observed change scores. We examine appraisal processes associated with having GRC-observed change contradictions. METHODS: This secondary analysis of longitudinal multiple sclerosis (MS) registry data examined predictors of GRC scores in the whole sample (n = 858). Logistic modeling then examined predictors of membership in one of two paradoxical subgroups (n = 525): (a) Worsened GRC with unchanged observed Rand-12 Mental Component scores (MCS) (Symptom-Maximizers, n = 171) versus no change GRC among stable MCS subsample; and (b) same GRC with declined observed MCS scores (Symptom-Minimizers, n = 84) versus declining GRC among declining MCS subsample...
