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…

A group of manufactured chemicals called hydroxylated polychlorinated biphenyls, or OH-PCBs, which persist in the environment despite a ban on production, are associated with an increased risk of developing multiple sclerosis (MS), according to a new study. In turn, another family of compounds highly resistant to environmental breakdown, called…

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,…

Neurons, also called nerve cells, collected from brain lesions of people with multiple sclerosis (MS) were found to accumulate new genetic mutations at a significantly faster rate than healthy neurons did, according to a new report. The researchers also found that neurons in such lesions exhibited distinct mutation…

Black people with multiple sclerosis (MS) walk more slowly and cover shorter distances over a certain time period than white people with the disease, a study in the U.S. finds. While the differences were somewhat attenuated when other factors that may impact walking ability were considered, such as age,…

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…

Using a simple algorithm to recommend highly effective disease-modifying therapies (DMTs) for people with multiple sclerosis (MS) can help make treatment fairer for all patients, and level inequalities otherwise defined by race or ethnicity, a new study by U.S. researchers suggests. Indeed, use of the algorithm over a…

People with multiple sclerosis (MS) who switch from a high- to a moderate-efficacy disease-modifying therapy (DMT) increase their risk of disease activity, especially younger adults and those having inflammatory disease activity before a switch, a study finds. Knowing these factors “can help guide future studies on deescalation,” researchers…

Note: This story was updated March 6, 2025, to clarify the specific disability measures and results assessed in each trial.
