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…

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…

A number of genetic variations related to vitamin D metabolism were not significantly associated with the severity of multiple sclerosis (MS), according to a recent study. The study, “Role of Multiple Vitamin D-Related Polymorphisms in Multiple Sclerosis Severity: Preliminary Findings,” was published in Genes. In MS, the body’s immune…

A novel algorithm that combines genetic, environmental, and clinical data could be useful for predicting whether people with a first onset of multiple sclerosis (MS)-like disease — known as clinically isolated syndrome (CIS) — will experience relapses or a worsening of their disease over time. The…

Not drinking alcohol significantly increases the risk of developing multiple sclerosis (MS), especially if a person also is a current or former smoker, according to a new study. These findings add to the knowledge, discovered in multiple previous studies, that alcohol decreases the activity of the immune system. According…

A variation in a gene called STK11, previously shown to increase the risk for multiple sclerosis (MS) among Caucasians, is now also linked to a greater likelihood of MS in Black people. In fact, the variation was significantly more common in Black MS patients with secondary progressive MS (SPMS),…

Editor’s note: The Multiple Sclerosis News Today news team is providing in-depth and unparalleled coverage of the virtual ACTRIMS Forum 2021, Feb. 25–27. Go here to see the latest stories from the conference. While researchers make progress in pinpointing markers of disease progression in multiple sclerosis (MS), identifying those that signal…

The presence of a particular gut bacterium widely used in probiotics, called Lactobacillus reuteri (L. reuteri), was sufficient to increase disease severity in a mouse model of multiple sclerosis (MS), but only in genetically susceptible animals, a recent study shows. These findings highlight the complex interactions between…

A genetic variant may make depression more likely in certain people with multiple sclerosis (MS) than others, a genome-wide study in patients indicates. The study, “Depression in multiple sclerosis patients associated with risk variant near NEGR1,” was published in Multiple Sclerosis and Related Disorders. Depression is characterized by…

A comparison of immune cells isolated from identical twins — in which only one of each pair was diagnosed with multiple sclerosis (MS) — identified a population of immune-regulating T-cells present in those with asymptomatic brain inflammation, a study has found. …

Specific mutations in genes that provide instructions to make two proteins —  called C3 and C1q — are linked to increased severity of multiple sclerosis (MS), according to new research. The new finding will be presented by Johns Hopkins University School of Medicine researcher Peter Calabresi, MD, during…

Interaction between various Epstein-Barr virus traits and the composition of certain genes affects the risk of developing multiple sclerosis (MS), a study reports. The study, “The interaction of Multiple Sclerosis risk loci with Epstein-Barr virus phenotypes implicates the virus in pathogenesis,” was published in the journal…

An amino acid change to phenylalanine, and a specific class I HLA gene variant are associated with greater risk for multiple sclerosis (MS), according to a study in Japanese patients. Researchers also identified an HLA variant, or mutation, associated with neuromyelitis optica spectrum disorder (NMOSD), an autoimmune condition…

Scientists are zeroing in on mutations in a few genes that appear to be major risk factors for developing multiple sclerosis (MS). The results of their research suggest there are common biological pathways that cause the disease. The study, “Exome sequencing in multiple sclerosis families identifies 12…

A study found no genetic risk factors associated with vitamin D in families with a history of multiple sclerosis (MS), suggesting that the link between vitamin D deficiency and MS risk is determined by environmental factors rather than a genetic predisposition. The study “Exonic variants of genes related…

A collaboration between DNAnexus, the Sutter Health network, and the University Pittsburgh Medical Center (UPMC) aims to improve personalized medicine in multiple sclerosis (MS) through the first large-scale clinical genomic research study, the companies announced. The network has the goal of improving screening, diagnosis, and treatment of…

Risk factors often associated with multiple sclerosis (MS), such as genetic background, obesity and smoking, contribute independently to the disease’s variability and may be an early influence on progression, a study reported. The retrospective study, “Multiple sclerosis risk factors contribute to onset heterogeneity,” was published in the journal …

A person’s genes influence the development of multiple sclerosis (MS), but so does the environment — both that in which an MS patient lives, and that which a patient creates through diet and other lifestyle choices, researchers said in a Thursday session at the 34th congress of the European…

A person’s social network can have an effect on their functional disability. This is what researchers discovered when they applied an online assessment tool they developed to people at risk of developing multiple sclerosis (MS). The tool, developed by researchers from Brigham and Women’s Hospital, Broad Institute in Boston,…

The numbers of people being diagnosed with multiple sclerosis is rising worldwide, though distinct differences in factors thought to drive this rise are evident among regions, according to MS data represented by researchers on patients in Asia, Latin America, and the Australia-New Zealand. The data was part of the session “Prevalence and…

University of Southern California researchers are recruiting 400 Hispanics who have been diagnosed with multiple sclerosis in the past two years for a study about genetics’ and cultural perceptions’ effect on the severity of the disease. More specifically, the Keck School of Medicine team will look at whether the stressful process of…

The Americas Committee for the Treatment and Research in Multiple Sclerosis, otherwise known as ACTRIMS, says its third annual ACTRIMS Forum will take place Feb. 1-3, 2018, at the Hilton San Diego Bayfront in San Diego, California. These forums bolster the ACTRIMS mission, which is to foster the careers of young researchers interested in MS by promoting mentor relationships with senior scientists, and giving promising investigators a chance to present their early research findings. ACTRIMS 2017 was a record-breaking year with over 800 people attending. Organizers say 1,000 people will attend this year's conference. The 2018 forum's theme is “Therapeutic Targets in MS: The Frontier and the Future of Disease Modifying Therapy.” ACTRIMS 2018 also features continuing medical education credits for attendees, as well as participation grants for applicable young investigators.

A clinical trial of a smartphone app that helps multiple sclerosis (MS) understand and manage their disease — and to aid and speed research — is now recruiting people nationwide. Claimed to be the first of its kind, the app, called myMS, is designed to give MS patients quick and easy access to pertinent information, from clinical evaluations…

The second annual Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS), a forum for clinicians, researchers and other MS specialists to network and discuss the  latest advances in MS research and treatment is set for Feb. 23–25. This year’s meeting takes place at the Omni ChampionsGate resort hotel in Orlando, Florida. Multiple Sclerosis News…

The Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) recently announced that its second annual ACTRIMS Forum will be at the Omni ChampionsGate Feb. 23-25, 2017, in Orlando, Florida. ACTRIMS Forum 2017 promises to be of value to physicians, scientists, researchers, analysts, faculty, and allied health…
