About a third of people with relapsing-remitting multiple sclerosis (RRMS) exhibit cognitive impairments, according to a review by Australian researchers of 50 previously published studies. The findings suggest that cognitive issues might be somewhat less common in RRMS than previous reports have indicated, with prior estimates ranging from approximately…

Treatment with modafinil, a stimulant approved in the U.S. for treating certain sleep-related disorders, significantly reduced fatigue and improved overall quality of life when used in clinical trials for people with multiple sclerosis (MS), according to a review of published study data.

These findings…

People with multiple sclerosis (MS) have a twofold higher risk of seizures compared with the general population, according to pooled data from clinical trials. Among MS patients, treatment with sphingosine-1-phosphate receptor (S1PR) modulators, a class of MS disease-modifying therapies (DMTs) that includes the oral medications Gilenya (fingolimod),…

People with multiple sclerosis (MS) engage in significantly more sedentary behaviors — activities like watching TV or using a computer or smartphone versus those requiring physical movement, such as exercise — than do individuals without the progressive disease, according to a pooled analysis of published studies. This effect was…

A noninvasive brain stimulation technique called transcranial direct current stimulation (tDCS) can significantly improve walking abilities in people with multiple sclerosis (MS), according to a pooled analysis of published studies. The technique was effective when applied to the main brain region called the primary motor cortex, which is involved…

Women with multiple sclerosis (MS) have significantly lower relapse rates after entering menopause, but disability levels increase significantly in that period, according to a pooled analysis of studies. The findings are consistent with a decrease in immune activity with age and loss of estrogen, leading to fewer disease-related relapses,…

For people with multiple sclerosis (MS), all forms of exercise are likely to be beneficial for physical fitness, but certain forms of exercise may be better than others at improving specific measures of fitness, according to a review of multiple clinical trials. Results suggest that resistance training — pushing…

Rehabilitation therapy that utilizes virtual reality can help to improve balance and reduce the fear of falling for people with multiple sclerosis (MS), a new analysis shows. “Our findings provide support to the use of [virtual reality-based therapy] to recover balance in neurological diseases such as MS,” researchers wrote.

Celiac disease, in which the ingestion of gluten causes the immune system to attack the lining of the small intestine, is not common in people with multiple sclerosis (MS), a meta-analysis found. While the diet-caused autoimmune disease  is estimated to affect between 0.2% and 0.7% of people in the…

Infection with the stomach bacterium Helicobacter pylori (H. pylori) does not appear to protect against the development of multiple sclerosis (MS), a review study has found. However, when researchers focused on studies that used microscopic assessments of tissue instead of other diagnostic methods to detect H. pylori, their data…

Aquatic exercise therapy can help to ease fatigue and improve balance in people with multiple sclerosis (MS), without notable side effects, according to a review of published studies. These findings have important implications for MS patients, as fatigue is among the main symptoms of the disease and…

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…

Robotic-assisted gait training (RAGT) may be the most effective form of physical exercise for improving mobility among people with severe multiple sclerosis (MS), according to a recent review study. Other exercise types, such as conventional walking, treadmill training, and yoga, may also be feasible and effective, however, the researchers…

Autologous hematopoietic stem cell transplant (aHSCT), a procedure that aims to “reset” the immune system, generally reduces disability and relapse rates in people with multiple sclerosis (MS), according to a new meta-analysis. “Current data encourage a broader application of AHSCT for treating patients with MS while still considering…

The risk of erectile dysfunction was about three times greater in men with multiple sclerosis (MS) compared with healthy men, according to a recent meta-analysis of published studies. It was identified in nearly half of the 2,760 adult male patients in these studies, highlighting the importance of diagnosing…

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…

Trigeminal neuralgia, a chronic pain condition characterized by shocks or burning sensations in the face, seems to be much more common among people with multiple sclerosis (MS) than in the general population, according to a review of published studies. This condition also is more prevalent in women with…

The therapeutic administration of mesenchymal stem cells can improve functional abilities and promote the restoration of lost myelin in rodent models of multiple sclerosis (MS), according to a new analysis of published studies. The findings highlight the potential of these stem cells, but also point to a need for…

Anti-CD20 antibody therapies that target B-cells are highly effective for reducing the risk of relapses in people with relapsing-remitting multiple sclerosis (RRMS), a new analysis confirms. The analysis did not find any significant differences in efficacy or safety among the anti-CD20 therapies currently approved to treat RRMS, though…

An imaging feature called a rim lesion is found in about 4 out of every 10 people with multiple sclerosis (MS), according to a review study. These rims, thought to represent areas of chronic brain inflammation in which myelin is being progressively damaged, may serve as alternate biomarkers of…

Probiotic supplements could ease disability, lessen depression, and improve overall health in people with relapsing-remitting multiple sclerosis (MS), according to an analysis of four randomized clinical trials. Physicians working with these patients might recommend “confirmed probiotic supplements” to help manage “MS concerns,” its scientists wrote, while noting that studies…
