Smoking Linked to Worse Outcomes in RRMS Patients After 10 Years

Smoking is associated with lower brain volume, more brain lesions, and greater disability and attention deficits among people with relapsing-remitting multiple sclerosis (RRMS) after 10 years,Ā according to a study in Norway. “The findings imply that patients should be advised and offered aid in smoking cessation shortly after diagnosis, to…

Researchers Distinguish Remyelinated Brain Lesions Via MRI

An MRI technique called quantitative susceptibility mapping (QSM) can be used to accurately identify remyelinated brain lesions in people with multiple sclerosis (MS), a research team has discovered. Remyelinated lesions are those in which the myelin sheath ā€” the protective coating around nerve fibers that is progressively lost…

Nerve Tissue Scarring May Explain MS Progression

Nerve tissue scars associated with multiple sclerosis (MS) show marked differences from those of similar neurodegenerative disorders, according to a recent study. MS-associated inflammation causes brain and spinal cord lesions (nerve tissue scarring) that often are bigger and last longer than those of two other demyelinating diseases: myelin oligodendrocyte…

New Spinal Cord Lesions Can Be Evident in Stable MS Patients

Asymptomatic damage to spinal nerves occurs even in clinically stable cases of multiple sclerosis (MS) and carries an increased risk for further lesions, a recent study suggests. Although a firm link between the asymptomatic loss of myelin in the spine and worsening disability remains to be found, this work…

Biogen Presents Update on its MS Therapeutic Portfolio

Biogen has released new data on several of its therapies for multiple sclerosis (MS), including Vumerity (diroximel fumarate), Tecfidera (dimethyl fumarate), and Tysabri (natalizumab). The data ā€” six presentations ā€” originally were to be presented at the 2020 annual conference of the American…

7T MRI Reveals New Insights into Some RRMS Features

With the help of 7 Tesla magnetic resonance imaging (MRI), investigators discovered that leptomeningeal enhancement ā€” a radiographic finding indicative of brain inflammation ā€” is more common than previously thought in people with relapsing-remitting multiple sclerosisĀ (RRMS), and is tied to lesions in specific regions of the brain.
