}After decades of intensive research, the pathogenesis of multiple sclerosis (MS) remains enigmatic. Neuroimaging has fueled the discovery of hitherto underestimated or unknown pathophysiologic aspects of MS, revealing, for example, widespread damage to normal-appearing white matter and cortical and

Multiple sclerosis (MS) is a chronic, progressive central nervous system disease characterized by distributed white matter injury. Particularly prevalent in Canada, MS is a leading cause of…
Morphological MRI phenotypes of multiple sclerosis differ in resting-state brain function
- Psychology, BiologyScientific Reports

The amount of focal white matter pathology but not global brain atrophy affects connectivity in the central SMN (leg area) of the SMN, consistent with the notion of a disconnection syndrome.
Resting-state Functional Network Disruptions in a Rodent Model of Mesial Temporal Lobe Epilepsy (TLE)
- Biology, Psychology
- 2015
Graph theoretical network modelling and analysis revealed significant increase in functional connectivity connectivity to the temporal lobe (hippocampus) in epileptic-rats compared to controls in the limbic, and “default mode” network, which suggests extensive disruptions in brain networks affected by TLE.
Altered Inter-Subregion Connectivity of the Default Mode Network in Relapsing Remitting Multiple Sclerosis: A Functional and Structural Connectivity Study
- Biology, PsychologyPloS one
- 2014
The relationship between MS-related structural abnormalities and clinical markers suggests that the disruption of this long-distance “inter-subregion” connectivity (white matter) may significantly impact the integrity of the network's function.
Reproducibility of Resting State Connectivity in Patients with Stable Multiple Sclerosis
- Medicine, PsychologyPloS one
- 2016
In both stable MS and HC mean functional connectivity across the entire network did not reach acceptable ICCs for several networks but a high reproducibility of ROI ICCs and of the ratio of overlap was found, which supports the utility of rfMRI to monitor functional changes related to disease progression or therapeutic interventions in MS.

It is suggested that it is unlikely to ever achieve a satisfactory level of explanation and prediction of an individual patient’s condition-based solely on morphologic information, although such insights might be better suited to define disease progression than clinical assessment.

This topical review provides an overview of fMRI research, but also highlights limitations of existing fMRI studies with cross-sectional design and offers recommendations for designing future research studies to overcome previous methodological shortcomings.

It is demonstrated that, compared with control subjects, patients with SCI showed increased functional connectivity between primary motor cortex and other motor areas, such as the supplementary motor area and basal ganglia, however, decreased functional connectivity in the sensorimotor cortex of patients withSCI.

Using a cognitive fMRI paradigm, this work was able to confirm adaptive changes of neuronal activation with progressing MS and to provide strong evidence for their compensatory nature, at least partially.

The results suggest that bilateral brain networks, beyond those normally engaged in motor tasks, are recruited during a simple hand movement in patients with benign MS, and this increased activation is probably the expression of an extensive, compensatory and tissue-damage related functional cortical reorganization.

These findings imply a complex and diverging relation of anatomical and functional connectivity in early multiple sclerosis and add an important observation for understanding how cognitive abilities and CNS integrity may be reflected in the intrinsic covariance of functional signals.
Intellectual enrichment lessens the effect of brain atrophy on learning and memory in multiple sclerosis

It is shown that greater intellectual enrichment lessened the negative effect of brain atrophy on cognitive performance in multiple sclerosis (MS) and that education-dependent cognitive compensation, as shown for cognitive compensation in RRMS, could be limited by tissue damage accumulation and disease progression.

Is Speed of Processing or Working Memory the Primary Information Processing Deficit in Multiple Sclerosis?

Deficits in Processing Speed were much more common than Working Memory in all comparisons and strongly suggest that the primary information processing deficit in persons with MS is in speed of processing.
