BCG vaccine to prevent tuberculosis not linked to MS risk: Study

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…

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…

Alcohol Consumption Is No Protection From MS: UK Study

The risk of developing multiple sclerosis (MS) doesn’t seem to be influenced by consuming alcohol, according to a large-scale analysis in the U.K. After adjusting for known MS risk factors, including smoking, childhood obesity, socioeconomic status, or genetics, the findings remained the same. The analysis was published in Nature…

Review Gives ‘Cautious Support’ to Childhood Trauma as MS Risk Factor

Most available studies suggest a connection between childhood trauma and multiple sclerosis (MS), from earlier symptom onset to potentially poorer outcomes, but more research is needed to understand this association, a review paper highlights. While several high-quality studies have been published, the scientists noted “considerable heterogeneity [variability] in methodology, including inconsistencies…

Beer Consumption May Be Linked to MS Risk: Meta-analysis

Alcohol intake is not significantly associated with an increased risk of developing multiple sclerosis (MS), but specifically drinking beer may elevate the risk, according to a recent meta-analysis. The association, however, was limited by a small number of included studies. “Further large-scale prospective studies should be conducted to verify…

Eating Beans, Vegetables May Reduce MS Risk

Eating a lot of green leafy and other vegetables, beans, nuts and berries seems to significantly lower the likelihood of developing multiple sclerosis (MS), according to a study from Iran. The findings also suggest that the chances of developing the disease may be higher in people who eat more…

T. Gondii Parasite May Protect Against Developing MS

Toxoplasmosis, an infection by the parasite Toxoplasma gondii, has a protective effect against the development of multiple sclerosis (MS), according to a review study. Specifically, people who had been infected with the parasite were 32% less likely to develop MS than those who never had toxoplasmosis. While these findings support T. gondii…
