Exercise improves mental health, life quality for MS patients: Analysis

Getting physical exercise can improve subjective well-being and health-related quality of life for people with multiple sclerosis (MS), a new meta-analysis shows. “Exercise interventions, especially aerobic or combined aerobic and resistance training, should be implemented in clinical practice to promote mental health” and health-related quality of life in people…

ACTRIMS 2024: Progressive MS patients show gains in NG-01 OLE

Repeated treatment with the mesenchymal stem cell therapy NG-01 led to gains in mobility and cognition, along with patient-reported quality of life, for most people with progressive multiple sclerosis (MS) in an extension study. Markers of nerve damage were also reduced, indicating significant nerve-protecting effects. Dimitrios Karussis, MD,…

ACTRIMS 2024: Molecule made by gut bacteria seen to ease MS in mice

Supplements of indole 3-lactate (ILA), a molecule made by gut bacteria, significantly reduced disease severity and promoted myelin repair in mouse models of multiple sclerosis (MS). That’s according to new findings presented by Larissa Jank, PhD, a postdoctoral researcher at Johns Hopkins University, at the Americas Committee for Treatment…

Dark rim on MS lesions seen with standard MRI may mark activity

An imaging feature called the T1-dark rim, which is visible on standard MRI scans of people with multiple sclerosis (MS), could help to identify paramagnetic rim lesions (PRLs), a study suggests. PRLs are regions of chronic active inflammation that cause ongoing nerve damage. They’re associated with disease activity and…

Treatment of progressive MS hits milestones in recent years: Review

Treatment options for progressive types of multiple sclerosis (MS) have expanded dramatically over the past decade, and several promising experimental therapies are in late stages of clinical development, a new review paper highlights. The study, “Clinical trials for progressive multiple sclerosis: progress, new lessons learned, and…

Online therapy platform found to boost mental health of patients

COMPASS, a digital tool that provides support for managing the daily challenges of living with a long-term health condition such as multiple sclerosis (MS), significantly reduces psychological distress and improves mental health in these patients, data from a randomized clinical trial show. The intervention consists of multiple online modules…

Researchers call for more pragmatic clinical trials in MS

Few multiple sclerosis (MS) clinical trials have used a so-called pragmatic design, which evaluates the effectiveness of interventions in real-life routine practice, a study has found. Because such trials are better able to emulate conditions in real-world clinical practice and provide solid and more actionable evidence to inform treatment…

Real-world data can be used to compare efficacy of MS treatments

Real-world data collected from a registry can be used to reliably compare the effectiveness of different multiple sclerosis (MS) treatments, so long as appropriate methodologies are employed to account for the messiness — what researchers call confounding bias — of real-world data, according to a new study. While registries…

Myelin repair early in MS may protect against disability worsening

People in the early stages of multiple sclerosis (MS) who have more spontaneous myelin repair in the cortex — the outermost layer of the brain that’s critical for higher cognitive abilities — are less likely to experience worsening disability, a new analysis suggests. These findings have important implications for…

Ancient DNA reveal how MS risk genes arose, spread across Europe

Genetic changes that predispose people to developing multiple sclerosis (MS) first emerged among herding populations who migrated to Eastern Europe thousands of years ago and then spread across the continent, new research has found. Researchers think these genetic variations may have helped turbocharge the immune system, making it easier…
