BACKGROUND AND PURPOSE: Cognitive deficits affect≤ 30% of patients with PPMS. We
investigated the functional correlates of cognitive network dysfunction in patients with PPMS …

Brain magnetic resonance imaging (MRI) and an extensive battery of neuropsychological
tests exploring frontal functions, short and long-term memory, visuo-spatial skills, attention …

Background and purpose The differences in cognitive function between primary progressive
and secondary progressive multiple sclerosis (MS) remain unclear. We compared cognitive …

Objectives To characterize cognitive impairment in primary progressive multiple sclerosis
(PPMS) and to correlate the pattern of cognitive deficits with brain magnetic resonance …

Although cognitive dysfunction is known to occur in multiple sclerosis (MS), only few studies
have reported cognitive performance in patients with primary progressive MS (PPMS). To …

Cerebral reorganization may limit the effects of central nervous system tissue damage on
cognition in patients with multiple sclerosis (MS). This study investigated fMRI activation …

Objectives: To identify associations between cognitive impairment and imaging measures in
a cross-sectional study of patients with primary progressive multiple sclerosis (PPMS) …

Background Heterogeneous processes may contribute to cognitive impairment in multiple
sclerosis (MS). Objective To apply a longitudinal multiparametric MRI approach to identify …

Functional magnetic resonance imaging (fMRI) data on motor function have shown adaptive
functional changes related to brain injury in multiple sclerosis (MS). We investigated whether …

In this multicenter study, we applied functional magnetic resonance imaging (fMRI) to define
the functional correlates of cognitive dysfunction in patients with multiple sclerosis (MS) …
