MS lesions

People with multiple sclerosis (MS) visited doctors, were admitted to the hospital, and used emergency care more often than other people more than two decades before their diagnosis, a large study finds. The use of these services peaked in the year before a diagnosis, but visits to a primary…

Mesenchymal stem cell (MSC) therapy is safe and well tolerated, and leads to improvements in disability and a reduction in lesion burden in people with multiple sclerosis (MS), according to a review of published studies. MSC treatments also reduced levels of biomarkers associated with nerve damage and inflammation,…

Treatment with neural stem cells, which have the ability to differentiate into neurons and other supportive cells of the nervous system, was safe and significantly boosted myelin repair in spinal cord lesions in a mouse model of multiple sclerosis (MS), a study showed. The stem cells were able to…

In healthy adults, a single low dose of Immutep’s immunosuppressive candidate IMP761 continues to be safe and appears to reduce the activity of T-cells — immune cells that become overactive in multiple sclerosis (MS) and other autoimmune diseases. This is according to data from an ongoing Phase…

A new imaging technology may help detect early signs of brain damage in people with multiple sclerosis (MS) that aren’t visible on conventional MRI scans, a recent study shows. The technology detects specific metabolic alterations in the brain by tracking certain metabolites and neurotransmitters — molecules that nerve…

The first person with multiple sclerosis (MS) has been successfully imaged in a clinical trial evaluating a new positron emission tomography (PET) tracer designed to detect changes in myelin loss, or demyelination. The Phase 1 study (NCT04699747), a joint effort between Quantum Biopharma and Massachusetts…

Gum disease caused by the bacterium Porphyromonas gingivalis (Pg) is associated with worse multiple sclerosis (MS) in a mouse model of the disease, a study shows. Infection with Pg directly or indirectly boosted pro-inflammatory pathways in immune cells in the spleen, where they’re produced, thereby aggravating MS. These effects…

Pro-inflammatory signaling molecules that have been implicated in multiple sclerosis (MS) cause problems with the growth and development of myelin-making cells in the brain, according to a study done in cell models. The findings may have implications for treating MS, as promoting the growth of myelin-making cells could be…

While subtle symptoms of multiple sclerosis (MS) — like muscle weakness, fatigue, and numbness or unusual sensations — are often overlooked in individuals with minimal disability, more detailed clinical tools can help detect these early signs, according to a new study from Italy. Moreover, such tools — including wearable…

A particular finding on an MRI scan, called the central vein sign (CVS), is sufficient to support a multiple sclerosis (MS) diagnosis without the need for an invasive lumbar puncture, a new U.K. study suggests. The presence of six lesions with a CVS, where a vein is found…

The Epstein-Barr virus (EBV) — a well-established risk factor for multiple sclerosis (MS) — is able to alter the movements of infected immune cells, a new study reveals. The findings shed new light on how EBV may set the stage for MS to develop, and could potentially form…

Of all of the cognitive functions that multiple sclerosis (MS) can affect, memory and processing issues have been my primary burdens. I’ve found them difficult to navigate and manage, especially when others don’t fully understand the extent to which they affect me. My MS-related cognitive impairments have resulted…

Treatment with masitinib, an experimental therapy being developed by AB Science for progressive forms of multiple sclerosis (MS), reduced markers of nerve damage and inflammation and slowed disease progression in a mouse model of MS. “This study is the first to demonstrate that masitinib can lower serum NfL…

People with multiple sclerosis (MS) who experience progression independent of relapse activity (PIRA) tend to have greater damage to major white matter tracts, or bundles of nerve fibers that connect different regions of the brain, a new study reports. The findings offer some insights into the biological processes that…

Certain lesions in the spinal cords of people with multiple sclerosis (MS) show damage to nerve fibers despite having normal myelin, according to a study done on postmortem samples using powerful MRI scans paired with detailed tissue analyses. The identification of these lesions “provides a novel opportunity to detect…

Wider rims of immune cells surrounding multiple sclerosis (MS) lesions in the brain and spinal cord are associated with faster disease progression, a new study shows. Monitoring this type of lesion may help track MS disease progression and measure how the disease is responding to treatment, and the…

Octave Bioscience’s Multiple Sclerosis Disease Activity (MSDA) test, which uses data from blood biomarkers to assess multiple sclerosis (MS) disease activity, is now available across all 50 U.S. states to help guide clinicians’ decisions about care. Octave said the test received certification from the New York State Clinical…

Well, it’s that time of year again, and I’m not referring to allergy season or baseball. It’s time for my MRI to evaluate my multiple sclerosis (MS). For the last three years, I was getting an MRI every 18 months. But at my last visit I saw a…

Early treatment with Ocrevus (ocrelizumab) may help protect the cerebellum, a region of the brain that plays a key role in motor coordination, cognitive function, and emotional regulation, from damage in people with multiple sclerosis (MS), a study suggested. Data from the clinical studies that supported Ocrevus’ approval…

Assessing multiple sclerosis (MS) disease activity using Octave Bioscience’s MS Disease Activity (MSDA) blood biomarker test can help guide clinicians’ decisions about care, a study showed. “Our goal is to empower both providers and patients with precision tools that transform MS care,” Doug Biehn, CEO of Octave, said…
