Active clinical trials for "Sclerosis"

This study aims to assess the following research questions: Map and benchmark the gut microbiome of patients with RRMS, and PPMS versus matched healthy controls Determine whether RRMS or PPMS have a unique bias for a gut microbiome classification recently characterized. Search for relationship with inflammation, amino acid plasma levels, heart rate variability (vagus nerve tone) and hair cortisol as a biological marker of chronic stress Determine whether the gut microbiome is different in MS patients during a relapse. Determine whether the gut microbiome remains stable after 3 months

Multiple sclerosis (MS) is a chronic immune central nervous system (CNS) disease of unknown cause. Recent studies suggest that gut microbiota could be a trigger for the neuro-inflammation in MS and abnormal gut microbiota composition has been reported in MS patients. These data provided scientific rationale for microbiota-directed intervention, like stool transplant, for the treatment of MS.

The aim of this study was to determine the muscle architecture of the lower extremity muscles (pennation angle, muscle fiber length and muscle thickness) in patients with multiple sclerosis. Lower extremity muscles of patients with multiple sclerosis and healthy individuals; rectus femoris, biceps femoris, tibialis anterior, gastrosoleus and gastrocnemius muscles will be examined by ultrasound method.

Multiple sclerosis (MS) is an autoimmune disease, leading to inflammation and degeneration of neurons in the entire central nervous system (CNS). Not only does MS attack CNS white matter, the wiring of the brain, but it also affects so called grey matter, involved in communication between brain cells. Some studies have shown that grey matter damage and lesions to the outermost layer of the brain, the cortex, might serve as a better diagnostic and prognostic tool for MS patients. The issue is that cortical lesions only to a limited extent can be visualized by conventional magnetic resonance imaging (MRI) at 3 tesla. The new generation of ultra-high field MR scanners with a field strength of 7 tesla, has a higher sensitivity towards detecting these cortical lesions. We therefore wish to use the improved sensitivity of ultra-high field MRI to improve detection of cortical lesions, and to elucidate the detrimental effects of single lesions to the cortex, thereby improving both diagnosis and prognosis of the disease. By implementing newly developed ultra-high-resolution MR-sequences the amount and extent of cortical lesions to the area of the brain responsible of the sensory and motor function of the hand (sensorimotor hand area - SM1-HAND) will be investigated in patients with relapsing remitting and secondary progressive MS. We will also assess how these lesions affect manual dexterity and sensory function and how cortical lesions affect communication within brain areas. It is hypothesized that the amount and size of cortical lesions is highly involved in brain communication and manual function, a major problem in MS, and that this project will shed new light on how the disease damages this important brain area.

The objective of this study to investigate, if learning and recall of a sequence of body movements (steps that realize a pattern on the ground) can be improved by self-produced music (having particular melodic-structures in relation to the pattern), compared to the same sound (a single tone) for each pattern in persons with multiple sclerosis compared to age and gender matched controls

The aim of this survey is the evaluation of the responsiveness and the estimation of the MCID of the German and French Multiple Sclerosis Questionnaire for Physiotherapists, a self-rating Patient Reported Outcome questionnaire. This multicenter project uses a combined anchor and distribution based approach with multiple anchors to provide a range of MCID estimates or a single MCID for the reliable and valid Items, Activity and Participation group and the Total Score of the MSQPT, which should to be used as guidelines in daily practice.

This study will evaluate the effects of Aubagio on changes in the brain using MRI.

Background: - Some people have a mutation in the C9ORF72 gene that causes amyotrophic lateral sclerosis (ALS) or frontotemporal dementia (FTD). The mutation causes a small piece of DNA to repeat itself thousands of times. The C9ORF gene mutation mostly occurs in families. In those families, some persons have ALS and others have FTD. Occasionally the C9ORF gene mutation occurs in persons without a family history. Researchers want to understand how this gene causes different diseases. They will study how symptoms caused by the C9ORF gene develop and change over time. They will measure symptoms that occur in ALS and in FTD. In particular, they will measure strength, ability to move, thinking, and memory. They will also see if other tests are associated with progression of disease. These tests, called biomarkers, may help detect or measure C9ORF72 disease in the future. Objectives: - To understand how symptoms change over time in people with mutations in a gene called C9ORF72, which causes ALS and FTD. Eligibility: - Adults over age 18 who have this genetic mutation Design: Participants will have up to 4 in-person visits and 3 telephone interviews over 3 years. Each in-person visit may take place over several days. They may be either inpatient or outpatient visits. At each visit, participants will undergo a series of brain, language, and behavior tests. These will include: Magnetic resonance imaging (MRI) of the brain. This uses magnets, radio waves, and computers to produce detailed pictures of the brain. Collecting spinal fluid. The clinician will make the participant s back numb and then insert a needle to collect fluid. <TAB>- Blood samples will be taken. <TAB>- Participants will be asked to perform several language and movement tests. <TAB>- Small skin samples will be taken on one visit - Between visits, participants will answer questions about their health over the phone 3 times.

Study aims: The primary aim is to determine whether chewing efficiency, determined by a two-colour mixing ability test, and maximum bite and lip force decrease in ALS patients.

This trial seeks to investigate brain network changes following cognitive rehabilitation in MS patients. The investigators hypothesize that rehabilitation interventions improve connectivity in the brain.Novel Magnetic Resonance Imaging technique is performed to investigate changes in brain plasticity.
