Canada has one of the highest rates of multiple sclerosis (MS). MS patients experience disabling motor, visual, and sensory symptoms, and a high risk of comorbid major depressive disorder (MDD) and severe fatigue. The lifetime prevalence of MDD in MS patients is about 50%, and nearly 90% experience severe fatigue, both of which are not responsive to typical treatments. Repetitive transcranial magnetic stimulation (rTMS) is a first line, Health Canada approved non-invasive neurostimulation treatment for MDD. rTMS induces electrical activity in the cortex using magnetic fields generated outside of the head to drive neuronal firing in the target site. However, MS is typically an exclusion criterion due to safety concerns. The goal of this clinical trial is to learn if repeated transcranial magnetic stimulation (rTMS) can be used to treat depression symptoms in adults with multiple sclerosis (MS). rTMS is a non-invasive form of brain stimulation that uses magnetic pulses to stimulate specific parts of the brain. The main questions it aims to answer are: Is rTMS safe, tolerable, and feasible to deliver as a treatment for depression and fatigue symptoms in individuals with MS? Does rTMS show preliminary effectiveness in improving depression and fatigue symptoms in this population? Researchers will determine whether rTMS treatment improves mood, fatigue, and cognition across time points (baseline, after treatment, and 4-week follow-up). Participants will: Complete screening, questionnaires, clinical assessments, cognitive tests, a brain MRI to help tailor the TMS treatment, and receive daily TMS sessions for 5 consecutive days, including: Pre-TMS brain mapping, five rTMS treatments (3 minutes) per day, separated by one hour. A safety and tolerability questionnaire will be administered daily. Complete post-treatment assessments (questionnaires, cognitive tests, psychiatric evaluation). Complete a 4-week follow-up visit, in person or virtually. Wear a fitness tracking watch during the study so researchers can collect activity data remotely. About 20 people will take part in this study through the University of Calgary.

This study compared two educational methods. Participants were assigned to participate in a 360-degree experience or a slideshow presentation. The 360-degree video group included a brain and MS program. The comparison group was given a slideshow presentation with the same information. Participants viewed the 360-degree program or the slideshow presentation only once. The online-based materials consisted of a demographic form (age, gender, race and ethnicity, and name of school), knowledge questionnaires, and an experiential learning scale. Pre-intervention, participants were asked about demographic information, whether they had previous experience with MS, the science classes they completed in high school and college, and their knowledge of the human brain and MS pathophysiology. At both pre- and post-intervention, participants completed the Multiple Sclerosis Magnetic Resonance Imaging Knowledge Questionnaire (MSMRIKQ) and the Multiple Sclerosis Knowledge Questionnaire (MSKQ). At post-intervention, participants completed a lesson experiential questionnaire about their experience viewing either the 360-degree video or the slideshow presentation. Permission to use the three instruments was obtained from their respective copyright holders.

The main purpose of this study is to assess whether hyperpolarized carbon imaging in relapsing remitting multiple sclerosis (MS) patients can be used to predict response to anti-CD20 disease modifying therapy. Study procedures will include magnetic resonance imaging (MRI) assessments with a hyperpolarized pyruvate sequence, clinical assessment as well as blood markers of disease progression. This method of imaging utilizes the Warburg effect, where innate immune cells utilize a metabolic shift to glycolysis instead of oxidative phosphorylation. In pre-clinical data, increased hyperpolarized lactate production has been found to be associated with increased microglial/macrophage infiltration in the brain. Although hyperpolarized carbon imaging in humans has been established and used in the field of oncology, this will be one of the first applications of hyperpolarized carbon the study of neuroinflammation in humans. We predict that hyperpolarized carbon imaging may have the potential to monitor and evaluate neuroinflammation in MS, and in particular the innate immune activation state that plays a role in MS progression. This imaging method may provide non-invasive monitoring of disease progression and therapy response for MS patients.

The purposes of this study are to: 1) compare baseline muscle and cardiovascular health in older individuals (\>60 years old) diagnosed with MS to age-matched people without MS, 2) determine muscle and whole body changes to an exercise training program, 3) determine if the muscle in a more affected leg in individuals diagnosed with MS is different from the muscle of a less affected leg, and 4) if or how individuals diagnosed with MS adapt differently than age-matched people without MS to exercise training. Participation in this study will average 1.5 hours per visit, 3 visits per week, for approximately 4 months.

People with neurological conditions often have difficulty walking, including problems such as foot drop. Functional electrical stimulation (FES) is a treatment that uses electrical signals to activate muscles and support walking. The L300 device is designed to help lift the foot during each step. This study will evaluate how using the L300 affects walking performance. Researchers will measure walking speed, step length, and walking symmetry using objective gait assessment tools. The study will also explore whether people with different neurological conditions respond differently to FES. The goal of this research is to improve understanding of how FES influences walking and to support more personalized rehabilitation approaches.

The goal of this clinical trial is to treat male and female participants with two types of Multiple Sclerosis (MS) called primary progressive or secondary progressive MS. The main questions the trial aims to answer are the following: * Is TRX319 safe when administered to patients with progressive forms of MS? * At what dose does TRX319 work the best to treat participants with primary and or secondary progressive MS? * Is pre-conditioning (with Bendamustine) needed to allow TRX319 to better treat participants with primary and/or secondary progressive MS? Participants will be asked to be on study for up 1 year and may receive up to 3 total administrations of TRX319. While on study, participants will have blood tests and other assessments (MRI scans and lumbar punctures) done to understand the safety of TRX319 and how it may benefit their multiple sclerosis.

The goal of this clinical trial is to learn if the time an individual eats each day impacts neurological health in people with multiple sclerosis. The main questions the investigators are asking are: 1. Does meal timing affect biomarkers of neuronal health (neurofilament light chain \[NfL\] and BDNF) and inflammation (IL-6, IL-17, TNF-ɑ) in adults with MS. 2. Does meal timing affect expression of circadian clock genes and genes associated with autophagy in adults with MS. Participants will be instructed to start and stop eating at specific times each day based on their group assignment and their personal schedule. They will respond to prompts sent to them on their smartphone to record the times they start and stop eating each day. As a secondary goal, the study will also explore the feasibility of including translocator protein (TSPO)-PET imaging of neuroinflammation in future clinical trials of TRE in people with MS. To accomplish this, imaging will be completed in a subset of 8 participants at the beginning and end of the study.

The purpose of this study is to assess and compare how well multiple sclerosis (MS) patients tolerate cetirizine versus diphenhydramine as a pre-medication before receiving anti-CD20 infusion therapy of ocrelizumab, ublituximab or rituximab. The study will also compare the safety of cetirizine versus diphenhydramine as a pre-medication for preventing infusion reactions in MS patients receiving anti-CD20 infusion therapy.

Multiple sclerosis (MS) is a common disease of the central nervous system that affects almost 1 million people in the United States. However, diagnosing MS can be difficult and often leads to misdiagnosis. More sensitive and specific biomarkers are needed to help with the diagnosis, prognosis, and evaluation of treatment response for MS. The central vein sign (CVS) and the paramagnetic rim lesion (PRL) are two biomarkers that have shown promise in improving diagnostic accuracy for MS. The goal of this study is to provide pilot information on the long-term performance of the CVS and PRL to help diagnose and follow people with MS. The study will follow 40 participants over 48 months to determine if the CVS and PRL help make a diagnosis of MS and how they can be used to follow people with MS. The study will also examine how PRL and CVS change over 48 months. The results of this pilot study will inform the development of a grant application to extend 5-year follow-up for all 420 participants of the CAVS-MS study. The study will use high-resolution T2\*-weighted MRI to detect the CVS and PRLs. An MRI of the brain with contrast will be used to examine CVS, PRL and longitudinal analysis of lesions that slowly grow over time (slowly expanding lesions \[SELs\]). The results of this study have the potential to improve the accuracy of diagnosing and treating MS.

The proposed study is a pilot study of ublituximab involving people with multiple sclerosis (MS) who are experiencing a "wearing off" phenomenon (return or worsening of MS-related symptoms) while being treated with ocrelizumab, and exploring whether switching to ublituzimab can resolve, improve or delay this phenomenon.

The study involves a two-arm, Phase 1, randomized controlled clinical trial designed to establish the feasibility and effects of a Functional Balance Intervention (FBI) on physical and cognitive function, as well as measures of daily living among persons with multiple sclerosis (PwMS). Combined Specific Aims: Aim 1: Examine the effect of the FBI (Intervention Group) on physical function in PwMS compared to a stretching program (Control Group). Hypothesis 1: After four months of training, the FBI group will show significantly greater improvements in physical function compared to the stretching group. Aim 2: Examine the effect of the multicomponent FBI on cognitive function in PwMS compared to the stretching program. Hypothesis 2: After four months of training, the FBI group will show significantly greater improvements in cognitive function compared to the stretching group. Aim 3: Examine the effects of the multicomponent FBI compared to the Control Group among PwMS on measures of daily living (dual-task performance, balance confidence, community mobility, and quality of life). Hypothesis 3: After four months of training, the FBI group will show significantly greater improvements in measures of daily living compared to the stretching group. All assessment sessions will be conducted virtually via Zoom. All measures collected during the initial screening, pre-training assessment, training progression, and mid- and post-training assessment sessions will be administered either via Zoom with a Helper Buddy present or through survey links sent to participants via the UIC REDCap system. The training sessions will be performed independently by the participants in the presence of a Helper Buddy. The investigators will recruit 75 people with multiple sclerosis (PwMS) for this study. Eligible participants will be randomized to either the FBI (Intervention) or stretching (Control) group, followed by an onboarding session with a designated Helper Buddy. Training will occur twice weekly for four months. Based on the anticipated attrition rate, the investigators aim for 40 PwMS to complete the post-training assessments and finish the study.
