Note: This story was updated April 4, 2025, to clarify the specific disability measures and that tolebrutinib is believed to target smoldering neuroinflammation. The U.S. Food and Drug Administration (FDA) has granted priority review to an application from Sanofi seeking the approval of its BTK inhibitor…

Treatment with Tysabri (natalizumab) may help delay disability progression in people with secondary progressive multiple sclerosis (SPMS) over Rebif (interferon beta-1a), an analysis of data from two clinical trials suggests. While the trials initially failed to demonstrate slowing disease progression, a significant benefit was observed when accounting…

Artificial intelligence (AI) platforms did better than most neurologists at answering a 20-question assessment about multiple sclerosis (MS) in a recent study, suggesting that AI may be a helpful tool for MS care. Neurologists with an MS specialty scored as well, on average, as the AI platforms, while neurology…

Antibodies that target proteins from the Epstein-Barr virus (EBV) also can inadvertently attack proteins in the brain, which may help to explain the link between EBV and multiple sclerosis (MS), a new study shows. Findings also indicate that antibodies targeting EBV as well as a person’s genetics both…

In the lymph nodes of the neck of people with multiple sclerosis (MS), certain immune cells show abnormalities in activity and signs of reactions against the Epstein-Barr virus (EBV), a new study reports. The findings may help to explain the connection between MS and EBV, researchers said. The study,…

In people with multiple sclerosis (MS), lesions that get slowly bigger over time, potentially due to chronic inflammation, are associated with more myelin loss throughout the brain, a study found. Loss of myelin was observed in these slowly expanding lesions, in other types of lesions, and also in regions…

A statistical model that takes clinical and demographic factors into account could help guide treatment decisions in people with relapsing-remitting multiple sclerosis (RRMS) who haven’t yet started on a multiple sclerosis (MS) therapy, a study reports. “Our study offers a predictive tool that fulfills an unmet need for…

Antibodies against a protein found in neurons and in nerve supporting cells, may play a role in driving multiple sclerosis (MS), a study indicates. Researchers examined immune responses against more than 23,000 human proteins, and the MLC1 protein emerged as one of the top hit proteins targeted by immune…

Interactions between the body’s immune system and bacteria that live in the digestive tract — essentially, a person’s gut — become disrupted in multiple sclerosis (MS), a new study by U.S. researchers found. The human intestines are home to billions of bacteria and other microorganisms, collectively known as the…

Using an implantable scaffold to collect immune cells in mice, researchers have gained insights into the immunological mechanisms driving primary progressive multiple sclerosis (PPMS). Based on the findings, the scientists developed a treatment strategy to block specific inflammatory molecules, which eased MS severity in the mouse model. The study,…

Navigating the uncertainty of living with relapsing-remitting multiple sclerosis (RRMS) brings a number of challenges, a study shows. That uncertainty is best described as the intangible, difficult to define space between hope — the sense that things might get better or at least not turn out so badly —…

Children with multiple sclerosis (MS) who were exposed to sunlight for at least half an hour per day during the first summer of life tend to have less disease relapses than those who received less sun exposure during that period, a study found. The risk of relapse was also…

Experts in Australia and New Zealand have published the first consensus guidelines for the care of adults with multiple sclerosis (MS) in those countries, a step designed to help general practitioners and neurologists navigate the new MS treatment landscape. “Through these guidelines, we aim to support safe, timely and…

The rate of relapses in children with pediatric-onset multiple sclerosis (POMS) tends to increase around the time that menstruation begins, a new study reports. The findings suggest hormonal changes at the onset of puberty may trigger higher disease activity. The use of oral and infusion disease-modifying therapies (DMT)…

Smoking and obesity are both independently associated with faster disease progression in multiple sclerosis (MS), but when both risk factors are present together, a synergistic effect results in faster disease progression than can be explained by either alone. “Smoking and obesity significantly interacted to increase the risk of disability…
