Relapsing-Remitting Multiple SclerosisThe primary objective of the study is to determine which baseline and yearly response factors (clinical and para clinical) predict overall disease-free status at Month 12 and Month 24, and clinical disease-free status in subsequent Months 36 and 48. The secondary objectives are: To identify prognostic factors at Baseline that predict overall disease-free status at Month 12, and to assess if yearly overall disease-free response factors predict overall disease-free status at Month 24; To evaluate clinical disease-free status (relapse, Expanded Disability Status Scale [EDSS]) at each analysis time point of Months 12, 24, 36, and 48; To identify prognostic factors at Baseline that predict clinical disease-free status at Month 12, and to assess yearly clinical disease-free response factors that predict clinical disease-free status (relapse, EDSS) in subsequent years at Months 24, 36, and 48; To evaluate the impact of Tysabri at each analysis time point of Months 12, 24, 36, and 48 on the following: annualized relapse rate (ARR), sustained EDSS progression and improvement (24-week sustained); To evaluate the impact of Tysabri at each analysis time point of Months 12, 24, 36, and 48 on the following: magnetic resonance image (MRI) measures: T2, T1, T1 with Gadolinium (Gd), brain atrophy; To evaluate the impact of Tysabri at Month 24 and Month 48 on the following: optical coherence tomography (OCT), Low and High Contrast Visual Acuity Assessment; To evaluate the impact of Tysabri at each analysis time point of Months 12, 24, 36, and 48 on the following: cognitive impairment (Symbol Digit Modalities Test [SDMT]), capacity for work (Work Productivity and Activity Impairment Questionnaire [WPAI]), quality of life (QoL) (Multiple Sclerosis Impact Scale [MSIS-29])

Comparison Between Clinical and MRI Multiple Sclerosis Activity and Expression of Human Endogenous...
Multiple SclerosisMultiple sclerosis is the most common autoimmune inflammatory disease of the central nervous system. It is known that your etiology has genetic and environmental causes. Several viruses have been implicated as triggers as well as perpetrators of this disease. Several studies make the correlation between Endogenous Retrovirus Type W (HERV-W) and the family Herpesviridae and activity in the pathogenesis of multiple sclerosis. The most important characteristics of the virus implicated in the pathogenesis of the disease is the fact that they have latency periods of exacerbation and they have, as their main biological environment, the central nervous system. The HERV-W, Epstein-Barr virus (EBV), cytomegalovirus, herpes virus type 6 and type 7 herpesvirus members are the most studied as causes of multiple sclerosis. It was found that these viruses are closely involved in the pathogenesis of MS, but it is believed that aren't the only responsible for its beginning. It is likely that this disease presents numerous triggers and more studies are needed to determine these interactions. In addition, a study comparing the activity of multiple sclerosis with the presence of these viruses was never realized.

Default Mode Network in Multiple Sclerosis
Multiple SclerosisThe study will evaluate connectivity regardless whether patients present a clinical type that requires medical treatment. In this point, investigators will include patients with progressive evolution as well as initial forms of the disease (CIS) and properly established forms of multiple sclerosis (MS) in remittent-recidivant (RR) forms. The researches will not focus on medical treatment as some of these clinical forms have no indication for disease modifying drugs.
Impact of Multiple Sclerosis From the Viewpoint of the Caregivers
Multiple SclerosisHalf the MS patients require a natural (non professional) caregiver's support for daily living activities and this level of investment increases with the degree of disability. The caregiver's role is an essential key factor in the "therapeutic alliance" between the patient and heath professionals. The impact on the natural caregivers' Quality Of Life (QOL) and their expectations for the global quality of management are not documented, notably because of the lack of adapted tools. The aim of the investigators' project is to develop, from the caregivers' point of view, a standardized questionnaire evaluating 1) their QOL as related to the disease of the assisted and 2) their expectations concerning the global quality of professional management (care, coordination, information...). 1) their quality of life (QOL) as related to the disease of the assisted and 2) their expectations concerning the global quality of professional management (care, coordination, information...). The original tool validated will complete the palette of those that the investigators are developing to evaluate the quality of care of MS patients according to different dedicated organizations (formal networks or not, focused on the patients or professionals).

Patient Acceptable Symptomatic State and Minimal Clinically Important Difference of the Fatigue...
Multiple SclerosisFatigue is the most common symptom and the most disabling symptom of Multiple Sclerosis, and its inefficient management can be a source of multiple consultations (increase in health costs) and a reduction in productivity (work stoppages). Hence the need to define the most effective therapeutic strategy to reduce fatigue in Multiple Sclerosis. One of the aims of this project is to provide clinical indicators that can serve as evaluation criteria for determining the most effective fatigue management strategy in Multiple Sclerosis. The primary objective of the study is to determine the Minimal Clinically Important Difference (MCID) and the Patient Acceptable Symptomatic State (PASS) for fatigue in Multiple Sclerosis. The source population consists of all people with Multiple Sclerosis living in Lorraine and registered in the Lorraine Registry of Multiple Sclerosis (RelSEP).
Identification of Retinal Perivascular Inflammation in Patients With Multiple Sclerosis Using Adaptive...
Relapsing Remitting Multiple SclerosisProgressive Multiple Sclerosis5 moreUsing a technique called adaptive optics imaging applied on retina, investigators aim to gain access to vascular changes that could occur early in the course of Multiple Sclerosis (MS) and which could reflect vascular changes occurring along the optic nerve of the brain parenchyma. Indeed, our team has been able to develop a quantitative method to measure the perivascular infiltrate in the retina of patients with various inflammatory retinal disease. It has been observed in MS patients that this perivascular infiltrate can also be detected in the retina. However, its distribution across MS phenotypes (relapsing or progressive MS, with and without optic neuritis) is still unknown.
