Background: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system with a degenerative component, leading to irreversible disability. Mesenchymal stem cells (MSC) have been shown to prevent inflammation and neurodegeneration in animal models of MS, but no large phase II clinical trials have yet assessed the exploratory efficacy of MSC for MS.

Methods/design: This is an academic, investigator-initiated, randomized, double-blind, placebo-compared phase I/II clinical trial with autologous, bone-marrow derived MSC in MS.

Magnetization transfer ratio (MTR) is a semi-quantitative measure that seems to correlate with the degree of myelin loss and generally tissue destruction in multiple sclerosis (MS). Our objective was to comprehensively assess the MTR of lesions and normal appearing (NA) tissue separately in the white matter (WM), the cortex, the thalamus and the basal ganglia (BG) and determine their relative contribution to disability. In this cross-sectional study 71 patients were included (59 with relapsing-remitting MS, 12 with secondary progressive MS).

Motion artifacts are a well-known and frequent limitation during neuroimaging workup of cognitive decline. While head motion typically deteriorates image quality, we test the hypothesis that head motion differs systematically between healthy controls (HC), amnestic mild cognitive impairment (aMCI) and Alzheimer disease (AD) and consequently might contain diagnostic information. This prospective study was approved by the local ethics committee and includes 28 HC (age 71.

Background: The development of predictors of multiple sclerosis (MS) disability is difficult due to the complex interplay of pathophysiological and adaptive processes.

Objective: The purpose of this study was to investigate whether combined evoked potential (EP)-measures allow prediction of MS disability after 20 years.

Methods: We examined 28 patients with clinically definite MS according to Poser's criteria with Expanded Disability Status Scale (EDSS) scores, combined visual and motor EPs at entry (T0), 6 (T1), 12 (T2) and 24 (T3) months, and a cranial magnetic resonance imaging (MRI) scan at T0 and T2.

Article Synopsis
  • The study aimed to investigate differences in spinal cord atrophy among multiple sclerosis (MS) subtypes and its potential as a diagnostic tool alongside other MRI markers.
  • The study involved analyzing the upper cervical cord cross-sectional area (UCCA) and correlating it with clinical disability in 440 MS patients from two centers, categorized into relapsing-remitting (RR), secondary-progressive (SP), and primary-progressive (PP) MS.
  • Results showed that patients with SP and PP MS had significantly smaller UCCA compared to RR MS, and UCCA correlated inversely with disability scores, suggesting its importance in assessing clinical status in MS.

Background: Cortical lesions (CLs) have been reported to be a better predictor for cognitive impairment than white matter (WM) lesions in relapsing-remitting multiple sclerosis (RRMS).

Objectives: The objectives of this article are to investigate the contribution of CLs and WM lesions to cognitive impairment in 91 patients with MS and clinically isolated syndrome, and to test potential associations of CLs and WM lesions with fatigue and depression.

Methods: Lesions were scored and segmented on 3D double inversion recovery sequences, according to their location (cortical, WM).

Background: Fingolimod 0·5 mg once daily is approved for treatment of relapsing multiple sclerosis (MS). In the phase 3, 2-year FREEDOMS (FTY720 Research Evaluating Effects of Daily Oral therapy in MS) study, fingolimod significantly reduced annualised relapse rates (ARRs) and the risk of confirmed disability progression compared with placebo. We aimed to investigate whether the beneficial treatment effect reported for the overall population is consistent in subgroups of patients with different baseline characteristics.

Persistent black holes (PBH) are associated with axonal loss and disability progression in multiple sclerosis (MS). The objective of this work was to determine if BHT-3009, a DNA plasmid-encoding myelin basic protein (MBP), reduces the risk of new lesions becoming PBH, compared to placebo, and to test if pre-treatment serum anti-MBP antibody levels impact on the effect of BHT-3009 treatment. In this retrospective, blinded MRI study, we reviewed MRI scans of 155 MS patients from a double-blind, randomized, phase II trial with three treatment arms (placebo, 0.

Over the past 15 years, MRI lesion activity has become the accepted surrogate primary outcome measure in proof-of-concept placebo-controlled clinical trials of new immunomodulating therapies in relapse-onset multiple sclerosis (MS). In parallel, the number of patients that are available for the placebo arm of trials has declined, and more-aggressive drugs are being developed. A critical review is warranted to ensure efficient MRI--and patient--resource utilization.

Background: Although grey matter damage in multiple sclerosis is currently recognized, determinants of grey matter volume and its relationship with disability are not yet clear.

Objectives: The objectives of the study were to measure grey and white matter volumes across different disease phenotypes; identify MRI parameters associated with grey matter volume; and study grey and white matter volume as explanatory variables for clinical impairment.

Methods: This is a cross-sectional study in which MRI data of 95 clinically isolated syndrome, 657 relapsing-remitting, 125 secondary-progressive and 50 primary-progressive multiple sclerosis patients from three centres were acquired.

Written language comprehension at the word and the sentence level was analysed by the combination of spatial and temporal analysis of functional magnetic resonance imaging (fMRI). Spatial analysis was performed via general linear modelling (GLM). Concerning the temporal analysis, local differences in neurovascular coupling may confound a direct comparison of blood oxygenation level-dependent (BOLD) response estimates between regions.

Corrective saccades are small eye movements that redirect gaze whenever the actual eye position differs from the desired eye position. In contrast to various forms of saccades including pro-saccades, recentering-saccades or memory guided saccades, corrective saccades have been widely neglected so far. The fMRI correlates of corrective saccades were studied that spontaneously occurred during fixation, pursuit or saccadic tasks.

Standard functional magnetic resonance imaging (fMRI) requires alternations between activation (ON) and baseline (OFF) periods to map the haemodynamic response to neuronal activation. Consequently, standard fMRI cannot map continuous activations in conditions like tinnitus without an ON-OFF paradigm. We present a novel approach to fMRI that allows mapping of continuous neuronal activation.
