People who had infectious mononucleosis — a contagious disease for which the Epstein-Barr virus (EBV) is the leading cause — had a higher incidence of multiple sclerosis (MS) in the 10 years following diagnosis compared with individuals not diagnosed with the virus, a study found. This link was particularly…

The risk of developing multiple sclerosis (MS) is lower in women with a history of pregnancy and is not affected by the use of oral contraceptives, according to a recent meta-analysis of four published studies. However, the four studies, conducted in the U.S. and Iran, showed considerable variability in…

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…

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…

Genetic variants that contribute to a high body mass index (BMI) during childhood are associated with an increased risk of developing multiple sclerosis (MS), a study found. The relationship is likely influenced by the fact that a higher BMI in childhood is linked to obesity in adulthood and a “longer…

Infection with the herpes simplex virus does not increase the risk of multiple sclerosis (MS), according to a new analysis based on genetic data. The study, “Mendelian Randomization Analysis Suggests No Associations of Herpes Simplex Virus Infections With Multiple Sclerosis,” was published in Frontiers in…

While people who smoke cigarettes are more likely to be diagnosed with multiple sclerosis, MS patients who are daily alcohol drinkers are more likely to show signs of faster neurodegeneration, a new study highlights. The findings suggest that quitting smoking and cutting back on alcohol would be beneficial for people…

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…

People who contract infectious mononucleosis — colloquially known as “mono” — during childhood or adolescence are at a roughly two to three times greater risk of developing multiple sclerosis (MS) as adults, a large population-based study suggests. Notably, the study points to mono itself — independent of other factors…

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…

Two genetic variants have been identified by researchers within a genome region previously reported to drive a 1.44-times increased risk of multiple sclerosis (MS) in a group of African Americans with European ancestry. Located in genes involved in immune responses, the variants fully explain the reported European ancestry-associated increased…

Young men, ages 16 to 20, with a higher the body mass index (BMI) are at greater their risk of being diagnosed with multiple sclerosis (MS) later in life, regardless of physical fitness, according to a Swedish study. Risk rose across “the entire BMI range,” its researchers reported,…

People exposed to secondhand cigarette smoke during adolescence may be more likely to develop multiple sclerosis (MS) later in life, a study suggests. The study, “Exposure to passive smoking during adolescence is associated with an increased risk of developing multiple sclerosis,” was published in the Multiple…

Getting plenty of sun, eating fresh fruits regularly and drinking coffee daily are associated with a lower risk for multiple sclerosis (MS) among adults in Saudi Arabia — while eating a lot of fast-food raises that risk, researchers report. Their study, “Environmental exposures and the risk of…

Multiple sclerosis (MS) is thought to be caused by genetic factors, but environmental cues are increasingly recognized to have an impact on disease onset and development. One environmental factor suggested to play a role in MS is infectious agents, such as viruses. Now, different teams of scientists have explored the…

The risk of developing multiple sclerosis (MS) later in life may be higher for babies born with low levels of vitamin D, according to a new study in the journal Neurology. The study, “Neonatal Vitamin D Status And Risk Of Multiple Sclerosis – A Population-Based Case-Control Study,” was…

A new research study published online in the Journal of Neurology, Neurosurgery & Psychiatry suggests that drinking six cups of coffee a day could lower the risk of developing multiple sclerosis (MS). The researchers said the neuroprotective and anti-inflammatory properties of caffeine in coffee may explain why drinking a…
