Active clinical trials for "Multiple Sclerosis"

Cognitive impairment is nowadays more and more recognized as an important feature of the multiple sclerosis (MS) disease. Cognitive disorders frequency in MS is estimated between 40 and 60%. Cognitive impairment affects quality of life and vocational status in MS patients. Until recently, little information was available on the cognitive dysfunction and their evolution that occur in primary progressive multiple sclerosis (PPMS) as compared with relapsing-remitting MS (RRMS). In PPMS pathological studies have shown the importance of cortical demyelination and meningeal inflammation suggesting that the GM alteration could play a major role in the cognitive impairment in this phenotype. The cognitive evolution and the brain tissue alteration at the origin of these difficulties remain poorly understood in PPMS. The use of new techniques for morphological and functional MRI can study the contribution of diffuse White Matter (WM) alteration (probably through disconnexion of relevant network) and diffuse Grey matter (GM) alterations in the cerebral cortex and other structures (the hippocampi, the cerebellum, and the thalami) in cognitive impairment in PPMS patients and on their evolution.

Multiple sclerosis (MS) is a chronic, immune-mediated, demyelinating disease of the central nervous system. Typical brain lesions of the disease may be partially repaired by an endogenous remyelination process which is limited and tends to deplete over the course of the disease. Cladribine tablets are an approved treatment that promotes selective lymphocyte depletion, reducing the inflammatory activity of the disease. The present study is based on the hypothesis that improved inflammatory control through cladribine tablets provides a tissue microenvironment more favorable for remyelination of brain lesions in MS. This hypothesis will be evaluated by a single-arm, open-label, phase IV, single-center, proof-of-concept clinical trial in which 10 participants with relapsing-remitting, highly active MS, relatively early in the course of the disease, will receive conventional treatment with cladribine tablets and will be followed-up for 48 months. Neurological, neuropsychological and magnetic resonance imaging (MRI) parameters will be measured. Remyelination will be assessed by a novel MRI technique called the q-Space myelin map. Additionally, the peripheral blood lymphocyte and cytokine profiles will be evaluated in order to understand the immunological aspects that influence the remyelination capacity in patients treated with cladribine tablets. The study will be conducted in accordance with current regulations governing clinical research in Brazil.

This study will explore the expression of PARP-1 in optic neuritis of multiple sclerosis patients. The data will be collected from Sohag University hospital in the period from the start of August 2021 to the end of December 2021. The study protocol will be approved by the Scientific Research Ethical Committee, Faculty of Medicine, Sohag University.

The focus of this work is the evaluation of a measure of cognitive functioning- intra-individual variability (IIV) - derived from a computer-based continuous reaction time (RT) task (Cogstate) as an early marker of prodromal MS.

Many patients with multiple sclerosis (MS) experience "relapses" of disease activity during which they have increased numbness, weakness, visual problems, or other symptoms. If a person with MS has new symptoms that are concerning to them, their doctor may want to see them in the office in order to confirm that these symptoms are due to a true "relapse" of activity before starting relapse treatment. This requirement can be frustrating for patients, who may have to take time off from work or travel long distances for such unexpected doctors' visits. In this study, the investigators will use input from patients with MS and MS physicians to create a relapse questionnaire that can be used to confirm a relapse has occurred. The investigators will also evaluate if having a more direct line of communication with the provider's office improves overall patient care and satisfaction.

This study aim to ensure that the implementation of a paramedical screening program and counseling in sexual health of patients with neurological pathologies (low-grade gliomas and Multiple Sclerosis) improves their sexual health.

The main gold of this study is to lead a multicentric, prospective study, to evaluate the diagnostic quality of tears in children with clinically isolated syndrome (CIS) and radiologically isolated syndrome (RIS) during a longitudinal follow-up.

We will tailor a telehealth obesity intervention for obese patients with MS (figure 2). Half of the patients will be randomly assigned to 24 weekly hour-long group weight loss sessions and 6 monthly individual sessions; half will be assigned to a brief education/Treatment as Usual (TAU) control condition. Participants assigned to the control condition will also receive the active treatment 6 months following their enrollment. As such, we will have feasibility, acceptability, and outcome data for all patients who enroll and complete the intervention. During outpatient recruitment, clinicians will ask obese patients (WHtR >.57, BMI >29) if they would be willing to be contacted about a study investigating a weight loss intervention for patients with MS. Patients who express interest and respond to advertisements will be screened by telephone and via review of medical records. Patients who meet initial eligibility criteria will be invited for a baseline evaluation where they will be formally consented, complete questionnaires and behavioral tasks, and undergo a standardized physical exam. They will be monitored using actigraphy for 10 days. They will then be randomized to the group telehealth obesity intervention or TAU. At 6 months, all participants will undergo a second in-person follow-up assessment and TAU participants will begin the telehealth intervention. At 12 months, participants will undergo a third in-person assessment, providing treatment outcome data for all study participants and long-term weight maintenance data for patients initially assigned to the telehealth obesity intervention. At 18 months, participants initially assigned to the TAU control condition will undergo a 4th assessment, providing weight maintenance data for all enrolled participants.

Background: Multiple sclerosis (MS) is an autoimmune disease that has no cure. MRI is the main tool used in the study and treatment of people with MS. A tracer has been developed for cyclooxygenase-2 (COX-2), an enzyme found in the brain during inflammation. Researchers want to explore the role inflammation plays in MS and see if COX-2 is measurable in the brains of people with the disease. Objective: To see if COX-2 is detectable in the brains of individuals with MS. Eligibility: People ages 18 and older with MS who are otherwise healthy. Design: Participants will be screened with their medical history and a physical exam. They will have an EKG to check the electrical activity of the heart. Participants study involvement requires 2 to 3 visits and will last between 1 week and 4 months. Participants will have 2 PET scans of the brain. These might occur on the same day or on separate days. A small amount of a radioactive chemical will be injected through an intravenous catheter. A needle will be used to guide a thin plastic tube into an arm vein. The needle will be removed. Only the catheter will be left in the vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. They will wear a plastic mask molded to fit the head. The scan will last about 90 minutes. Participants will receive the medication celecoxib orally about 2 hours before the second scan. Participants will have blood tests. Participants must avoid certain medications a month prior to the PET scans. ...

Through this study, a group composed of multiple sclerosis patients will be compared to a healthy volunteers group to determine if the positive emotions recognitions is preserved in the first group.
