Grey Matter Damage at the Earliest Phase of Multiple Sclerosis : a Longitudinal 7T MRI Study
Multiple SclerosisThe present study is an opportunity to assess grey matter damage at the earliest phase of Multiple Sclerosis (MS) allowing to a better understanding of its origins and its impact and disease severity. This study is a preliminary longitudinal study to precisely depict the kinetic of grey matter damage and the links with disease aggravation. Thirty MS patients without time and spatial dissemination criteria (only one symptomatic MRI lesion detected) but with oligoclonal bands detected on cerebro spinal fluid analysis will be included for a monocentric transversal MRI study at 7T to assess grey matter injury. Clinical and neuropsychological assessments will be performed in the population the same day of a multi-parametric MRI. A longitudinal clinical and MRI follow up will be performed during 2 years.

Secondary Sclerosis Cholangitis Prospective
Secondary Sclerosis Cholangitis in Critically Ill PatientsSC-CIP is increasing in patients after critical illness. Pathogenesis is still largely unclear. Gut microbiome composition, gut permeability, bacterial translocation, inflammation and/or genetic variants contribute to the pathogenesis The aim of this project is to study gut microbiome composition, gut permeability, bacterial translocation, inflammation, bile acid composition and genetic polymorphisms by conducting a prospective cohort study in patients with a high risk to develop SC-CIP.

Edinburgh Cognitive and Behavioural Amyotrophic Lateral Sclerosis Screen in Norway: A Validation...
Amyotrophic Lateral SclerosisCognitive ImpairmentCognitive impairment is present in about 30-50% of the patients with amyotrophic lateral sclerosis (ALS). Suitable screening tools are available, but none of these are evaluated in a Norwegian population.

MRI Study of the Mechanisms Underlying Irreversible Disability in Multiple Sclerosis
Multiple SclerosisMultiple sclerosis (MS) is the first non-traumatic cause of disability in young people, responsible for physical but also cognitive deficits. MS is an inflammatory demyelinating and degenerative disease of the central nervous system. Recently, MRI technics have demonstrated their sensibility to the different processes involved in MS. Particularly, MRI has evidenced that the pathological process of MS is not restricted to the macroscopic lesions of the white matter but also involves the normal appearing white and grey matter. In the normal appearing brain tissue, demyelination, neuronal suffering and neuronal loss have been evidenced. Moreover, MRI has demonstrated the existence of brain functional reorganization processes that may limit the clinical expression of pathological injuries. Despite these important findings, the pathological underpinnings of irreversible disability are largely unknown. The present project aims to depict the main determinants of physical but also cognitive disability in patients with MS. To do this, a longitudinal study including 70 patients with MS using different MRI markers known to be sensitive to the different pathological aspects of MS will be performed. The relationships between these markers and the progression of disability will be assessed. Identification of the main pathological underpinnings of irreversible disability of MS will provide the most relevant therapeutic targets.

ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD)
Frontotemporal Lobar Degeneration (FTLD)Progressive Supranuclear Palsy (PSP)12 moreARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration (ALLFTD) represents the formalized integration of ARTFL (U54 NS092089; funded through 2019) and LEFFTDS (U01 AG045390; funded through 2019) as a single North American research consortium to study FTLD for 2019 and beyond.

Postoperative Relapses in MS Patients
Multiple Sclerosis RelapseSurgery1 moreThe aim of the study is to record any relapses during one year postoperatively in patients and parturients diagnosed with MS who received general or regional anesthesia

Macromolecular Imaging of White and Gray Matter Pathology in Multiple Sclerosis
Multiple SclerosisMSThe overall purpose of this research is to determine whether new macromolecular measures optimized for whole brain (gray matter and white matter) magnetic resonance imaging (MRI), predict neuro-cognitive impairment in multiple sclerosis (MS) patients.

Biomarkers in Different Types of Amyotrophic Lateral Sclerosis (ALS) Patients Being Treated With...
Amyotrophic Lateral SclerosisThis study is being conducted to help the investigators better understand how the new FDA approved medication Edaravone (also known as Radicava) works in subsets of patients with ALS. The investigators are also trying to understand if there are specific ALS patients, with different presentations of ALS, who might benefit most from this medication. Also, the investigators are following specific biomarkers to determine the optimal treatment duration in patients with different forms of ALS There is no study medication being offered in this trial. Edaravone is prescribed as part of regular care. In this trial we are collecting blood, urine, and spinal fluid samples in ALS patients who are taking Edaravone and ALS patients who are not taking Edaravone to measure certain markers that could indicate why the drug may be working in a specific type of ALS.

Reliability and Validity of Outcome Measures for Pain in Multiple Sclerosis
PainThis project aims to provide values of test-retest reliability and insights from concurrent validity of outcome measures for pain in multiple sclerosis.

Phenotype, Genotype and Biomarkers 2
Amyotrophic Lateral SclerosisHereditary Spastic Paraplegia3 moreThe purpose of this study is to learn more about amyotrophic lateral sclerosis (ALS) and other related neurodegenerative diseases, including frontotemporal dementia (FTD), primary lateral sclerosis (PLS), hereditary spastic paraplegia (HSP), progressive muscular atrophy (PMA) and multisystem proteinopathy (MSP). More precisely, the investigator wants to identify the links that exist between the disease phenotype (phenotype refers to observable signs and symptoms) and the disease genotype (genotype refers to your genetic information). The investigator also wants to identify biomarkers of ALS and related diseases.
