A novel tracer designed to detect myelin loss in PET scans — imaging tests that use a radioactive substance, called a tracer, to look for disease in the body — showed a good safety profile in a small first-in-human study. Scientists say this new tracer could potentially help in evaluating…

Electrical stimulation of the brain through electrodes placed on the scalp may ease some measures of spasticity for people with relapsing-remitting multiple sclerosis (RRMS), according to results from a small clinical trial. Using this novel route of brain stimulation was shown to impact muscle contractions in patients with spasticity…

Autologous hematopoietic stem cell transplant (aHSCT) reduces markers of nerve fiber and myelin damage in people with relapsing-remitting MS (RRMS), according to a small study done in Sweden. “We investigated if therapeutic intervention with aHSCT could halt the injurious process leading to tissue damage in MS,” researchers wrote.

Guar gum, a type of dietary fiber that can be taken as a supplement, lessened inflammation and disease severity in a mouse model of multiple sclerosis (MS), a new study reports. While fiber-rich diets have long been recommended to improve overall health, these findings help pinpoint which fibers have…

A quick MRI-based method called SyMRI may be useful in future clinical trials to test experimental myelin-repairing therapies in diseases like multiple sclerosis (MS), a new study shows. The study, “Quantification of individual remyelination during short-term disease course by synthetic magnetic resonance imaging,” was published in Brain…

The Overall Disability Response Score, a combination of three different assessments of disability, could be used to more accurately evaluate the effectiveness of treatments in multiple sclerosis (MS) clinical trials, a new study illustrates. The score is composed of three measures commonly used to assess disability in MS, which…

A new machine learning tool could help make clinical trials for progressive forms of multiple sclerosis (MS) more efficient and effective, a study suggests. Its scientists propose that the tool, when used in initial patient studies, works to more rapidly move a potential progressive MS treatment into pivotal Phase…

Even in early stages of disease, people with multiple sclerosis (MS) commonly experience more difficulties performing cognitive and motor tasks simultaneously than do people without MS, a new study indicates. The study, “Cognitive-motor interference in people with mild to moderate multiple sclerosis, in comparison with healthy…

The rates of pregnancy complications are not higher in women with multiple sclerosis (MS) who were using disease-modifying therapies (DMTs) in the earliest stages of pregnancy, a study reported. The study, “Pregnancy outcomes after early fetal exposure to injectable first-line treatments, dimethyl fumarate or natalizumab in…

The likelihood of survival is about 7.5 times higher for people with multiple sclerosis (MS) who take their disease-modifying treatments as directed compared with those who do not, an analysis of data from U.S. veterans shows. The study, “Impact of Adherence with Disease-Modifying Therapies on All-Cause…

A robot-assisted training program that uses game-like activities to improve upper limb function was met with high satisfaction and enjoyment by people with multiple sclerosis (MS), a small study has found. Most of the participants reported the intervention improved their ability to do day-to-day activities, such as using a…

Treatment with GA Depot, an experimental long-acting form of glatiramer acetate that requires less frequent dosing than approved formulations, significantly reduced relapse rates among people with relapsing forms of multiple sclerosis (MS), according to top-line results from a Phase 3 clinical trial. “We are pleased with the topline…

In people with multiple sclerosis (MS) who show atrophy in a brain region called the thalamus, aerobic fitness is strongly correlated with standardized assessments of cognition and walking ability. However, these associations are not seen for MS patients who don’t have atrophy in the thalamus, according to a new…

The composition of bacteria in the gut is altered in multiple sclerosis (MS) patients compared with healthy people in the same household, a new study reports.
