An interplay between genetic and environmental risk factors, including tobacco smoke exposure, affects brain development in early childhood, which could increase the likelihood a person will develop multiple sclerosis (MS), according to a recent study. Among young children in the Netherlands, being at a high genetic risk for MS,…
Vaccination does not increase the risk of multiple sclerosis (MS) in children and adolescents within five years, a study found. Instead, there was a trend toward a lower risk of pediatric-onset MS in vaccinated children. This in line with earlier findings that vaccination is not a risk factor for…
Children with multiple sclerosis (MS) who come from poorer families or other disadvantageous circumstances tend to have more inflammation and irreversible brain tissue loss, a new study reports. “Our findings suggest that social disadvantage in childhood can have lasting effects on MS severity,” Kimberly A. O’Neill, MD, study coauthor…
Hospitalization for severe COVID-19 is significantly associated with a twofold higher risk of developing multiple sclerosis (MS), according to a study involving nearly the entire population of Sweden. No increased risk of MS was found among those who tested positive for SARS-CoV-2, the virus that causes COVID-19, or received…
Two enzymes in brain cells are responsible for mediating the toxic effects of certain fat molecules in multiple sclerosis (MS), a new study in a mouse model of the disease suggests. According to the researchers, these enzymes may serve as potential targets for easing neurodegeneration in people with MS.
Abnormal activity of ancient viral genes may play a role in the development of multiple sclerosis (MS) and other neurological disorders, a study found. “Future functional studies are essential to elucidate the molecular and cellular mechanisms underlying their involvement in these conditions,” the researchers wrote. The study, “…
People with multiple sclerosis (MS) who have multiple comorbidities, or co-occurring health problems, are more likely to experience disease activity and disability progression, according to a new analysis. Results indicate the risk of MS disease activity rises in patients who have at least one psychiatric diagnosis, as well as…
People with multiple sclerosis (MS) may have a slightly higher cancer risk than the general population, according to a recent study in France that reviewed a decade of data from more than 140,000 MS patients. The risk of bladder, brain, cervical, and kidney cancer was significantly increased in MS…
Having antibodies against the rubella virus is associated with an increased risk of developing multiple sclerosis (MS) in unvaccinated people, a Swedish study suggests. The findings show a rubella infection may be a risk factor for MS, reinforcing the hypothesis that certain viral infections may trigger the misleading immune…
Rituximab, which is sometimes used off-label for multiple sclerosis (MS), doubles the risk of hospital-treated infections, but may prevent worsening disability better than some approved disease-modifying therapies (DMTs), a Swedish study finds. Hospital-treated infections were significantly associated with a higher risk of relapse-independent disability worsening among relapsing-remitting…
Obesity promotes molecular signatures associated with more inflammation and multiple sclerosis (MS) signaling pathways specifically in females, which may explain the link between obesity and a higher risk of MS in women. These are the findings of a new study analyzing data not only from obese and non-obese women…
People with relapsing-remitting multiple sclerosis (RRMS) who drink low to moderate amounts of alcohol have significantly less disability progression in the years following diagnosis than non-drinkers, a study found. The trend was especially pronounced among women. Although the findings suggest that drinking alcohol may have beneficial effects in some…
A higher intake of whole grain food is significantly associated with a lower likelihood of developing pediatric-onset multiple sclerosis (MS), according to a study led by researchers in Canada. Conversely, an overall more pro-inflammatory diet — one containing higher amounts of fats and proteins — was linked to increased…
Among immigrants to Canada, the risk of multiple sclerosis (MS) is higher for those who have spent a greater portion of their life in Canada, a new study reports. The study, “Proportion of Life Spent in Canada and the Incidence of Multiple Sclerosis in Permanent Immigrants,”…
When I was initially evaluated for multiple sclerosis (MS), I was asked if I had a family history of the disease. To my knowledge, I did not. Once I received my diagnosis, one of the first things that crossed my mind, after recovering from the initial shock…
There’s no evidence to suggest that multiple sclerosis (MS) directly causes most cancers, but having the condition may marginally increase the likelihood of developing cervical cancer, according to a new study from China. That study found “no causal relationship between MS and 15 types of cancers except cervical cancer,”…
The risk of having a stroke, that is, a blockage in blood flow to the brain that can cause lasting damage, is about 2.5 times higher in people with multiple sclerosis (MS) than the general population, a review of multiple studies finds. The researchers called for further studies to…
People with multiple sclerosis (MS) in England had a seven times greater risk of hospitalization and a fourfold increased risk of death from COVID-19 in 2022 than did the general population, according to a study of almost 12 million people in the European nation. The elevated risk of both…
Scientists have created an assay that can measure immune cells’ inflammatory attack against the Epstein-Barr virus (EBV), a known risk factor for multiple sclerosis (MS). Researchers found preliminary evidence that some MS treatments, but not others, may alter the immune system’s response to EBV. The scientists said the…
The use of obesity medications — approved drugs for treating diabetes and promoting weight loss — is associated with a reduced chance of developing multiple sclerosis (MS), according to real-world data from the U.S. Food and Drug Administration (FDA), a study found. In particular, medicines that activate a receptor…
Obesity in childhood is associated with a more than double the risk of developing multiple sclerosis (MS) in adulthood, although the overall risk is low, according to a new study. “Our study adds to the evidence that obesity in early life increases the risk for a plethora of diseases…
Getting the Bacillus Calmette-Guerin (BCG) vaccine to protect against tuberculosis (TB) or having latent (inactive) TB in young adulthood aren’t linked to the risk of developing multiple sclerosis (MS), a Norwegian study found. The study, “BCG vaccination and multiple sclerosis risk: A Norwegian cohort study,” was published in…
Two types of chemicals in household disinfectants and furniture can disrupt the development of oligodendrocytes, the brain cells chiefly responsible for making myelin, a new study shows. The finding suggests that exposure to these chemicals may be a risk factor for disorders related to myelin such as…
