Patients with PIRA have more damage to white matter: Study

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…

Brain damage in MS children linked to lower socioeconomic status

Children with multiple sclerosis (MS) who come from poorer families or other disadvantageous circumstances tend to have more inflammation and irreversible brain tissue loss, a new study reports. “Our findings suggest that social disadvantage in childhood can have lasting effects on MS severity,” Kimberly A. O’Neill, MD, study coauthor…

More Microscopic Brain Damage Seen in SPMS Than in RRMS

People with secondary progressive multiple sclerosis (SPMS) have more microscopic damage in normal-appearing brain tissue than do patients with relapsing-remitting multiple sclerosis (RRMS), according to a new imaging study. These patients also have a greater number of chronic active lesions than those with RRMS. “Using advanced diffusion MRI…
