Severe cognitive impairment involving multiple cognitive domains can occur early during the course of multiple sclerosis (MS). We investigated resting state functional connectivity changes in large-scale brain networks and related structural damage underlying cognitive dysfunction in patients with early MS. Patients with relapsing MS (3-5 years disease(More)
BACKGROUND AND OBJECTIVE Cognitive and behavioural symptoms are common in multiple sclerosis (MS), but they are rarely the inaugural and predominant manifestation of the disease. Our objective is to characterize the clinical and radiological features of cognitive-multiple sclerosis (cog-MS), defined as MS subjects who entered into the disease with cognitive(More)
OBJECTIVE Using positron emission tomography (PET) with [(11) C]flumazenil ([(11) C]FMZ), an antagonist of the central benzodiazepine site located within the GABAA receptor, we quantified and mapped neuronal damage in the gray matter (GM) of patients with multiple sclerosis (MS) at distinct disease stages. We investigated the relationship between neuronal(More)
In all cases, the paraclinical investigations exclu-ded all potential differential diagnoses. All patients had extensive metabolic, infectious and immunological screening which was unremarkable. Neuro-myelitis optica (NMO) antibodies were negative for all patients. Visual Evoked Potentials (VEP) and Electromyography (EMG) were normal for all patients, as(More)
BACKGROUND Disabled multiple sclerosis (MS) patients often need intervention of multiple specialists, resulting in a complex organization of care. How this multidisciplinary care should be organized and structured has not been studied. OBJECTIVE The objective of this article is to address the effectiveness of an integrated multidisciplinary approach(More)
BACKGROUND Despite the high comorbidity of anxiety and depression in people with multiple sclerosis (MS), little is known about their inter-relationships. Both involve emotional perturbations and the way in which emotions are processed is likely central to both. The aim of the current study was to explore relationships between the domains of mood, emotional(More)
