Due to differences in sex chromosomes, certain immune cells cause more severe disease in males than females, according to a new study in a mouse model of multiple sclerosis (MS). The findings could help to explain why biological males with MS tend to have more severe disease. The study,…

Treatment with Mavenclad (clabridine) reduces the frequency of relapses in people with relapsing-remitting multiple sclerosis (RRMS), with benefits appearing to be evident two years after patients stopped taking the treatment, new data suggest. These findings were in the study, “Analysis of frequency and severity of relapses…

A new 3D model of the human nervous system is meant to mimic key processes in the development of the myelin sheath — the fatty coating around nerve cells that is damaged in multiple sclerosis (MS) — to help with research into treatments that promote myelination. This model might also…

People with relapsing-remitting multiple sclerosis (RRMS) using approved oral disease-modifying therapies generally tolerate the treatments well, with real-world adverse event profiles similar to those seen in clinical trials, an analysis of U.S. data indicates. Results also suggest high adherence to these therapies — meaning patients are usually taking the therapies…

Using artificial intelligence (AI) on imaging data collected from multiple sclerosis (MS) patients, researchers were able to classify these people into three new disease subtypes, each distinct from the current groupings determined by symptoms. These new subtypes may allow doctors to better determine those patients more likely to have…

A gene called Mertk has important roles in the repair of myelin, the fatty substance that surrounds and protects neurons and that is lost in multiple sclerosis (MS). The findings were published in Cell Press, in the study “Multiple sclerosis risk gene Mertk is required for…

The European Commission (EC) has approved a new method to administer Tysabri (natalizumab) as a treatment for people with relapsing-remitting multiple sclerosis (RRMS). This new delivery route involves a subcutaneous injection in which Tysabri is injected under the skin. Compared with the previously approved intravenous (into the bloodstream) formulation,…

People who develop multiple sclerosis (MS) as children are more likely to attain lower education levels, earn less in the workplace, and be more reliant on disability benefits later in life, new research shows. These findings were published in JAMA Neurology, in the study, “Long-term Socioeconomic…

Treatment with the antioxidant N‐acetyl cysteine is well-tolerated, but failed to outperform a placebo at easing fatigue in people with progressive multiple sclerosis (MS), a small clinical trial found. More studies now are needed to determine if oxidative stress contributes to fatigue or clinical progression in MS patients, and…
