smoldering lesions

Nearly one year of treatment with tolebrutinib, an oral small molecule being developed by Sanofi, failed to eliminate iron rim lesions in adults with multiple sclerosis (MS), according to data from a small Phase 2 clinical trial. Researchers are continuing to examine study results to determine…

An imaging feature called the T1-dark rim, which is visible on standard MRI scans of people with multiple sclerosis (MS), could help to identify paramagnetic rim lesions (PRLs), a study suggests. PRLs are regions of chronic active inflammation that cause ongoing nerve damage. They’re associated with disease activity and…

The presence of iron rim lesions (IRLs), which are regions of chronic nervous system damage with ongoing inflammation, visible on MRI scans, is linked with more substantial disability in people with multiple sclerosis (MS), according to a new study. However, the connection between these lesions and worse disability does not…

Raised serum neurofilament light chain (sNfL) levels may indicate the presence of brain lesions with chronically active inflammation that are linked with more aggressive forms of multiple sclerosis (MS), a new study suggests. People with high sNfL levels, the study revealed, had greater numbers of chronic inflammation lesions and…

Editor’s note: “Need to Know” is a series inspired by common forum questions and comments from readers. Have a comment or question about MS? Visit our forum. This week’s question is inspired by two forum topics about silent inflammation from August 2019. Have an experience you want…

Brain lesions appearing as dark rimmed, “smoldering” spots on imaging scans, representing active inflammation, may be a hallmark of more aggressive and disabling forms of multiple sclerosis (MS), researchers at the National Institutes of Health (NIH) report. Using a powerful MRI brain scanner and a 3D printer, the…
