Real-world Outcomes on Tecfidera (BG00012, Dimethyl Fumarate) Post-Tysabri (BG00002, Natalizumab)...
Relapsing-Remitting Multiple SclerosisThe primary objective of the study is to evaluate relapse activity, as measured by the proportion of participants relapsed at 12 months, in participants with relapsing-remitting multiple sclerosis (RRMS) who transition from Tysabri (BG00002) to Tecfidera (BG00012) in the real-world setting. The secondary objective is to further evaluate relapse activity, defined as annualized relapse rate (ARR), hospitalization and intravenous corticosteroid use, during the first year of Tecfidera treatment following transition from Tysabri treatment.

Evaluation of Coagulation in Multiple Sclerosis
Multiple SclerosisRecent research in multiple sclerosis (MS) have suggested that altered coagulation and vascular inflammation may play a role in pathophysiology of MS. Sonoclot is viscoelastic method of analyzing clot formation. This instrument will be used to compare coagulation in individuals with MS to healthy controls. A 24-hour dietary recall and food frequency questionnaire will help determine whether coagulation is modified by fish consumption.

Investigating the Relationship Between Sleep, Quality of Life,Other Disorders and Therapies in MS...
Multiple SclerosisThe study aims to investigate the relationship between sleep quality, quality of life,other disorders and therapies in Multiple Sclerosis (MS) patients treated with Betaferon.

Effectiveness of DMF and Its Impact on PROs in Suboptimal GA Responders With RMS
Relapsing Forms of Multiple SclerosisThe primary objective of the study is to estimate the annualized relapse rate (ARR) over a 12-month period in patients with relapsing forms of multiple sclerosis (MS) who are treated with dimethyl fumarate (DMF) after suboptimal response to glatiramer acetate (GA). The secondary objectives of this study in this study population are to assess the impact of DMF over a 12-month period on patient-reported outcomes (PROs) and health economic-related outcomes and to evaluate additional clinical outcomes at Month 12.

Biogen Multiple Sclerosis Pregnancy Exposure Registry
Multiple SclerosisExposure During PregnancyThe primary objective of the study is to prospectively evaluate pregnancy outcomes in women with multiple sclerosis who were exposed to a Registry-specified Biogen Multiple Sclerosis product during the eligibility window for that product. The Registry-specified Biogen MS products being studied are dimethyl fumarate, and Pegylated human interferon beta-1a. The secondary objective of the study is to prospectively evaluate pregnancy outcomes in women with MS who were unexposed to disease-modifying therapies (DMTs).

Prognosis Value of the Neuronal Damage in Early Multiple Sclerosis
Multiple SclerosisIn this study the investigators will use PET and 11C-Flumazenil to visualize and quantify neuronal injury in the cortex and the deep gray matter of Multiple Sclerosis patients at an early stage. The investigators will follow up patients to determine the prognostic value of this neuronal injury.

The Reliability, Validity, and Responsiveness of the Timed 360° Turn Test in Patients With Multiple...
Multiple SclerosisRelapsing-RemittingThe aim of the study is to investigate reliability, validity, and responsiveness of the timed 360° turn test in patients with Multiple Sclerosis.

Obstetric Anesthesia and Analgesia and Multiple Sclerosis
Multiple SclerosisAim of the retrospective study was to evaluate the influence of the labour on the clinical course of the parturients with MS in selected 6 month follow-up interval and to evaluate to possible influence of the different anesthesia/analgesia types on the course of MS.

Study to Assess OCT: RNFL and GCL in MS Patients
Multiple SclerosisThe purpose of this study is to collect preliminary data on retinal nerve fiber layer and ganglion cell layer damage in multiple sclerosis (MS) patients, using optical coherence tomography (OCT). For this study the Zeiss Cirrus OCT Imaging System will be used. The same system will be used consistently for the duration of the study.
