risk factors

Socioeconomic factors, specifically income and education levels, and marital status, were identified as risk factors for multiple sclerosis (MS) severity in a new study in Sweden. In fact, the study found that earning a higher income and having more years of education before being diagnosed with MS are associated with…

Researchers have developed a vaccine against the Epstein-Barr virus (EBV) — a leading environmental risk factor for multiple sclerosis (MS) — that induced durable immune responses in mice. If it’s moved to the clinic, the vaccine could help prevent infections that drive MS and certain cancers, according to…

Vitamin D reduced the signs of inflammation and nerve damage in a rat model of progressive multiple sclerosis (MS), a study shows. Low levels of the vitamin have been extensively linked with a higher risk of developing relapsing forms of the disease, but studies of vitamin D supplementation in…

A new artificial intelligence (AI) algorithm could help identify people at risk of developing multiple sclerosis (MS). “Our model’s performance suggests that AI-based prediction models could identify the risk for multiple sclerosis years before neurological symptoms appear,” Raj Gopalan, MD, a scientist at Siemens Healthineers, Tarrytown, New York, said…

What a person eats in childhood can influence their future risk of developing multiple sclerosis (MS) and its clinical course, according to a recent Dutch study. A poor diet with more fast food, snacks, and candy as a child tended to be associated with a higher risk of developing…

Relapsing-remitting multiple sclerosis (RRMS) patients with elevated levels of chloride in their cerebrospinal fluid (CSF), the fluid that bathes the central nervous system, may be at a higher risk of relapse, according to a study from China. Researchers propose that CSF chloride levels equal to or higher than 123.2…

Cigarette smoking significantly slows recovery time from a relapse for people with relapsing-remitting multiple sclerosis (RRMS), according to a pilot study in Iran. Similar links with relapse recovery were not seen for tobacco use with water pipes or exposure through second-hand smoke, also known as passive smoking. Findings add…

The protein DDX39B is a master regulator of immune tolerance, or the immune system’s ability to distinguish self from potentially harmful nonself molecules, and helps to control the development of immune cells that are key for this process, a new study shows. Findings suggest that activating DDX39B with small molecules…

Physical disability, not whether patients are depressed, when they’re diagnosed with multiple sclerosis significantly influences their future disability progression, according to a recent U.K. registry study. Although patients who were depressed at the time of their diagnosis were more likely to accumulate significant disability and require an aid to…

People with multiple sclerosis and a history of chronic opioid use are nearly 200 times more likely to use prescription opioids persistently, according to a study involving nearly 15,000 U.S. military veterans living with the neurodegenerative condition. A history of pain, paralysis, post-traumatic stress disorder, or living in a…

Welcome to “MS News Notes,” a Monday morning column where I comment on multiple sclerosis (MS) news stories that caught my eye last week. Here’s a look at what’s been happening: Yoga vs. physical therapy The MS News Today article “Yoga better than physical therapy at improving…

Sensoria Health and Padula Rehabilitation Technologies (PRT) have launched a wearable system crafted for optometry practices to improve balance, gait, and coordination, and to help reduce the risk of falls, particularly among older people. The system, NeurOpTrek powered by Sensoria, is designed to assess a person’s fall risk…

Women with multiple sclerosis (MS) may have a higher risk of giving birth to premature or smaller babies, but it’s unclear if using MS medications during pregnancy has an effect on the baby’s health, according to a systematic review. The long-term health outcomes of children whose mothers have…

Smoking and exposure to secondhand smoke are both associated with significantly faster disease progression in people with multiple sclerosis (MS), but snuff, a smokeless tobacco product placed behind the upper lip, seems to slow MS progression, a study in Sweden suggests. Findings also linked smoking and secondhand exposure, also…

People who drink black and green tea, coffee, and nonalcoholic beer may be significantly less likely to develop multiple sclerosis (MS), a study in Iran has found. In contrast, consuming carbonated beverages, milk, and natural fruit juices seems to increase the chances of developing the neurodegenerative condition, according to…

A pair of experts are calling for genetic tests to be developed to identify people at higher risk of developing progressive multifocal leukoencephalopathy (PML), a serious brain infection that can occur as a side effect of certain multiple sclerosis (MS) treatments. “The availability of a simple, relatively inexpensive test…

A new collaboration between ModeX Therapeutics and Merck, known as MSD outside North America, is expected to advance the development of ModeX’s MDX-2201, an investigational vaccine targeting the Epstein-Barr virus (EBV). A history of infection with EBV — known for causing infectious mononucleosis, or mono, and certain…

People infected with the human immunodeficiency virus (HIV) — including HIV-positive individuals who received antiretroviral treatment at some point after infection — are significantly less likely to develop multiple sclerosis (MS), a new analysis suggests.  The decrease in MS risk was particularly pronounced…

Eating too much salt can disrupt the energy metabolism of regulatory T-cells (Tregs), which normally work to control inflammation and fight autoimmunity, prompting them to adopt an inflammatory profile similar to what’s seen in multiple sclerosis (MS) and other autoimmune diseases, a study found. Even a short-term exposure to…

Teenagers with poor sleep quality or insufficient sleep — those who sleep less than seven hours a night — are 40% to 50% more likely to develop multiple sclerosis (MS) later in life than those who get adequate rest, according to a Swedish population-based study. Differences in sleep timing…

Smoking tobacco products is associated with a higher prevalence of depression and anxiety among multiple sclerosis (MS) patients, according to a recent systematic review. Across the evaluated studies, current smoking was linked to a 1.3–2.3 times higher prevalence of depression, and about a 1.2 times higher rate of anxiety.

People with relapsing-remitting multiple sclerosis (RRMS) who are receiving oral disease-modifying therapies (DMTs) are still more likely to experience a relapse or any form of disease activity if they are smokers, a study found. Researchers also observed that former smokers had a disease…

A protein in the virus that causes COVID-19 is structurally similar to several proteins targeted by the immune system in multiple sclerosis (MS), a new study shows. The results provide a potential mechanism for how COVID-19 could trigger MS-like disease in susceptible individuals, researchers said. The 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…

Higher activity of the genes SHMT1, FAM120B, and ICA1L in the brain may increase the risk of developing multiple sclerosis (MS), a new study reports that for the first time linked two of the genes to risk for the disease. The findings may help to better understand the biological…

Genetic variations in certain genes may increase the risk of developing progressive multifocal leukoencephalopathy (PML), a serious brain infection associated with certain treatments for multiple sclerosis (MS) and other conditions, a new study shows. The findings suggest that testing for four specific genetic variant could help to predict…

Among people with type 2 diabetes, the use of anti-hyperglycemic medications is associated with a reduced risk of multiple sclerosis (MS) for younger individuals, but an increased risk for older patients, particularly women. That’s according to the study “Age and sex differences on anti-hyperglycemic medication…

Scientists have identified a number of antibodies that can bind to the Epstein-Barr virus (EBV) — a major risk factor for multiple sclerosis (MS) — and prevent its infection of human cells. The antibodies might offer new approaches to treat or prevent infection in groups of people most…
