A model based on genetic factors could help predict the risk of developing multiple sclerosis (MS) in people with optic neuritis, an eye disorder that can be an early sign of MS, according to new research. “As a doctor caring for many patients with optic neuritis, I’m excited by…

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…

The risk of developing multiple sclerosis (MS) was similar between first- and second-degree family members of people with relapsing-remitting MS (RRMS) and primary progressive MS (PPMS). The findings, which were consistent with previous studies suggesting that genetics and environment are relatively equal contributors to disease risk, also…

People with multiple sclerosis (MS) are significantly more likely to have antibodies against the Epstein-Barr virus (EBV) — the strongest risk factor for the disease — than healthy individuals, as well as higher levels of these antibodies, according to a Spanish study. All MS patients were positive for anti-EBV…

People with a higher genetic risk for multiple sclerosis (MS) are significantly more likely to develop the disease at an earlier age, a large study found. Specifically, those with the highest genetic risk were on average five years younger at the time their symptoms started than those with the…

Skin Reactions ‘Frequent’ With Mavenclad, Real-world Study Finds I regularly see people posting on social media about having a rash or itchy skin, or losing hair while taking Mavenclad. Researchers in this study say these side effects aren’t mentioned in the risk management plans for this disease-modifying therapy. Therefore,…

Genetic variations that increase body mass index (BMI) in childhood are associated with a higher risk of multiple sclerosis (MS) regardless of a person’s vitamin D levels, a study found. The study, “BMI and low vitamin D are causal factors for multiple sclerosis,” was published in…

Researchers Discover How Key Genetic Risk Factor for MS Operates A genetic link to MS is something that some scientists have suspected for years. Now, there’s new research that targets a variation of a specific gene as possibly being that link. Scientists have uncovered the molecular mechanism…

A combination of mutations in two genes makes members of a Canadian family a 7-in-10 chance of developing multiple sclerosis (MS) — a radical increase from the 1-in-1,000 risk among the general population, according to a study that illustrates the huge impact certain genes can have on disease development. Interestingly, the…
